Take a look at our list of the financial terms associated with trading and the markets. From beginners starting their trading journey to experts with decades of experience, all traders need to clearly understand a huge number of terms.
Crude Oil, also known as West Texas Intermediate (WTI), is a light, sweet crude that acts as benchmark for oil prices in the US.
Crude Oil is priced in USD per barrel. It reached a historic high of $145.31 in July 2008 and saw a record low of $1.17 in February 1946.
WTI contains less sulphur than Brent Crude (which acts as a benchmark for oil prices in Europe and the Middle East), which means it demands a premium price. Both WTI and Brent are light, sweet oils that are ideal for refining into gasoline.
It is produced, refined and consumed in North America, and is mostly sourced in Texas - which is where the name originates - as well as in Louisiana and North Dakota.
WTI price is sensitive to factors that impact the general price of oil, as well as geopolitical and economic events and natural disasters in the Midwest and Gulf Coast regions.
Heating Oil is a low-viscosity petroleum product derived from crude oil. Around 25% of the yield of crude oil is devoted to heating oil, the second most after gasoline products. As a result, prices often closely follow those of WTI crude.
It is priced in USD per gallon, and has a historic high of $3.32 in April 2011. The record low was $0.87 in January 2016.
Heating oil is used as a fuel for furnaces and boilers to heat homes and businesses. It is especially popular in the British Isles and the North-eastern US. As a result, demand fluctuates seasonally, peaking in the colder months between October and March.
Price is, as a result, also affected by cold weather. Other factors affecting price include the price of alternative heating options, energy efficiency and insulation, refining costs and government regulations.
Heating Oil futures allow you to speculate on, or hedge against, changes in the price of Heating Oil. Futures rollover on the third Friday of every month.
The United States Oil Fund (USO) is an ETF that aims to track the daily price movements of WTI Crude Oil. USO's Benchmark is the near-month crude oil futures contract traded on the NYMEX. The Crude Oil contract is WTI light, sweet crude delivered to Cushing Oklahoma.
This ETF is a good way to get commodity exposure without using a futures account and offers more options for traders such as intraday pricing and limit/stop orders.
ProShares Ultra Bloomberg Crude Oil ETF (UCO) is a leveraged asset that seeks to deliver twice the daily investment results of the Bloomberg WTI Crude Oil Subindex. This is a single-day bet and is not suitable for buy-and-hold investors. Results can vary significantly if held for periods longer than one day. This is a leveraged ETF so traders take on more risk than with an unleveraged product.
ProShares UltraShort Bloomberg Crude Oil (SCO), aims to deliver results that are twice the inverse daily performance of the Bloomberg WTI Crude Oil Subindex. It is an ETF product for traders looking to short crude oil in a single day bet. Trades that last for more than a day are not expected to see the same returns.
The subindex reflects WTI Crude Oil prices and only consists of futures contracts on WTI Crude Oil. This is a leveraged product, all leveraged products carry more risk than unleveraged products.
A commodity is a raw material asset such as oil, gas, gold, or wheat. Commodities can be categorised into either hard commodities or soft commodities.
What are Soft Commodities?
Soft commodities typically refer to raw materials that are grown rather than mined such as coffee beans or sugar.
What Are Hard Commodities?
Whereas hard commodities must be extracted such as natural gas or crude oil.
A commodity is often exchangeable for other commodities of the same type and can be purchased through either the spot market using cash, or through derivatives like futures.
Energy Select Sector SPDR Fund (XLE) tracks US energy companies within the S&P 500. This asset uses the Energy Select Sector Index as its tracking benchmark. The ETF is offers concentrated exposure to oil and gas industry giants, as the S&P500 favours large-caps. Nevertheless, it is fairly representative of the whole energy market.
Just a few holdings make up a big part of the portfolio, and there are only 31 holdings in total. Top holdings for the benchmark index include Exxon Mobil Corp, Chevron Corp and ConocoPhillips.
DBC, also known as the PowerShares DB Commodity Tracking ETF, tracks 14 commodities based on the futures curve. It aims to limit the effect of contango and maximise the effect of backwardation so that investors improve their returns. The commodities included in the ETF are gasoline, heating oil, Brent crude oil, WTI crude oil, gold, wheat, corn, soybeans, sugar, natural gas, zinc, copper, aluminium and silver.
Unlike other commodity ETFs, DBC rolls future contracts based on the shape of the future curve, rather than following a schedule. This allows the ETF to generate the best roll yield by minimising losses and maximising backwardation.
NZD/CAD is the abbreviation for the New Zealand dollar to Canadian dollar exchange rate. The New Zealand dollar is the 10th most-traded currency, accounting for 2.1% of daily transactions. US$104 billion worth of NZD is traded daily. The Canadian dollar is the 6th most-traded currency, involved in 5.1% of all daily transactions.
The New Zealand dollar is highly-sensitive to commodity prices. Dairy is the country's main industry; when dairy prices fall, the outlook for the New Zealand economy weakens, pushing the NZD/CAD rate lower. When dairy prices rise, the opposite happens.
The Canadian dollar is heavily-exposed to changes in the price of crude oil - Canada's primary export. Both currencies are inversely correlated with the US Dollar, so even in times of risk movement in the NZD/CAD is more driven by fundamental factors.
The Canadian dollar is more exposed because the USA is Canada's largest trading partner by far.
The US Dollar to Indian rupee exchange rate is an exotic currency pair known by the abbreviation USD/INR. The US Dollar is by far the world's most-traded currency, accounting for 87% of all over-the-counter FX each day - $4.4 trillion. The rupee is the 18th most-active currency, accounting for 1.1% of daily transactions.
The US Dollar is not only the most ubiquitous currency on the globe, but also a safe-haven asset. As an emerging market currency, the rupee is popular in times of confidence and is sold when volatility increases. As a result of rising global trade tensions, INR weakened to record lows in the second half of 2018.
India is a net oil importer, so rising crude prices increase import costs, widening the current account deficit. Foreign direct investment (FDI) is key for the Indian economy, which benefits from overseas businesses looking to take advantage of the tax exemptions and lower labour costs.
Natural gas is a found deep underground, alongside coal and other fossil fuel deposits. It is extensively used in the US, accounting for 25% of US energy consumption. The gas primarily consists of methane.
It is priced in USD per British thermal units (mmBtu). The highest price recorded for Natural gas was $15.30 in December 2005, a record low of $1.02 was seen in January 1992.
Natural gas is used as a source of energy generation, especially for heating and cooling systems. It is often preferred to goal or oil as it produces less greenhouse gases than other fossil fuels.
Just ten countries account for close to 80% of the proven natural gas supplies in the world, with Russia sitting on 25% of total reserves. The Middle East is home to several the remaining top producers, excluding the US.
Gas futures allow you to speculate on, or hedge against, changes in the price of gas.
The AEX Index, known also as the Amsterdam 25, is a free float-adjusted and market capitalisation-weighted index of the 25 biggest and most actively traded companies trading in Amsterdam. It was created on January 3rd, 1983, but its base value of 538.36 is taken from 4th January 1999 to account for conversion to the euro.
The index recorded an all-time high in September 2000 of 701.56. It is the most widely-used bellwether of the Dutch stock market's performance.
The biggest sector in the index is Oil & Gas, which accounts for 17% of the total weighting. Personal & Household Goods, and Technology, are the second and third biggest sectors in the index respectively, each making up around 14% of the AEX.
Amsterdam 25 futures allow you to speculate on, or hedge against, changes in the price of stocks in the Netherlands market. The instrument is priced in euros and rolled over on the second Friday of every month.
CAD/CHF is the abbreviation for the Canadian dollar to Swiss franc exchange rate. US$260 billion worth of Canadian dollars and US$243 billion worth of francs is traded each day. The Canadian dollar is the 6th most-traded currency, and makes up one side in 5.1% of all daily trades. The Swiss franc is the 7th most-popular trading currency in the world and is involved in nearly 5% of all forex transactions each day.
The pair is sensitive to changes in market risk appetite, as the Canadian dollar is a commodity-correlated currency and the franc is a safe-haven currency.
The producing and exporting of crude oil is vital to the Canadian economy, so changes in price can push CAD/CHF higher or lower. Oil is sensitive to changes in risk appetite, creating further volatility for the Canadian dollar.
Compounding the effect of market uncertainty upon CAD/CHF is the Swiss franc's reputation as a safe-haven, thanks to Switzerland's strong economy and developed financial sector.
The Canadian dollar to Japanese yen exchange rate is identified by the abbreviation CAD/JPY. The Canadian dollar is the 6th most-popular currency, making up one side in 5.1% of daily trades. The Japanese yen is the 3rd most-traded currency, accounting for 22%.
The pair is highly sensitive to changes in market risk-appetite, as the Canadian dollar is a commodity-correlated currency and the Japanese yen is a safe-haven currency.
The Canadian dollar is highly sensitive to changes in the price of crude oil - Canada's primary export. In turn, crude prices often respond to market appetite for risk, so the strength of the CAD/JPY exchange rate is largely dictated by whether traders are feeling optimistic or pessimistic over global conditions.
In times of market uncertainty, appetite for the safe-haven Japanese yen can increase sharply. However, the yen is often softened by the Bank of Japan's ultra-loose monetary stimulus package, which includes quantitative easing and negative interest rates.
The US Dollar to Mexican peso exchange rate is identified by the abbreviation USD/MXN. The US Dollar is by far the world's most-traded currency, accounting for 87% of all over-the-counter FX each day - $4.4 trillion.
The Mexican peso is the 11th most-traded currency, accounting for 1.9% of daily transactions.
The US Dollar is not only the most ubiquitous currency on the globe, but also a safe-haven asset. In times of market uncertainty traders withdraw from riskier assets into stable USD. It is the most popular reserve currency
MXN is tied to the price of crude oil because of Mexico's high reserves, which the government uses as collateral when borrowing to fund spending. 10% of Mexico's GDP comes from oil production, so when prices fall it not only pushes up borrowing costs, but also weakens the outlook for growth.
Cross-border trade with the US also generates strong demand for pesos. The currency therefore weakens when trade comes under threat.
The pound Sterling to Canadian dollar exchange rate is identified by the abbreviation GBP/CAD. GBP is the 4th most-traded currency, accounting for 13% of all daily trades; US$649 billion worth.
Recently, political factors have seen their influence over the pound grow. This is because the Brexit referendum, which resulted in the UK voting to leave the EU, has created significant uncertainty regarding the UK economic outlook. Signs of upheaval in government as Downing Street tries to negotiate a Brexit deal that pleases all sides of the debate, as well as fears that the UK will crash out of the EU with no deal in place, weigh heavily on Sterling.
The Canadian dollar is highly-sensitive to changes in the US Dollar, as well as the price of crude oil, as this is Canada's main export. When oil prices fall, the outlook for the Canadian economy weakens, pushing the GBP/CAD exchange rate higher. When oil prices rise, the opposite happens.
West Texas Intermediate or WTI is a benchmark type of oil that is central to commodities trading. These benchmarks indicate quality and also the source of the oil. The three dominant benchmarks for oil are WTI, Brent Crude and Dubai/Oman. These are similar indicators as Scottish and Norwegian might be for smoked salmon, for example.
What is the difference between West Texas Intermediate and Brent crude?
The different benchmarks for oil come from different regions and have different chemical compositions. They have what are called 'quality spreads' and 'location spreads' which affect price differences.
What is West Texas Intermediate Used For?
West Texas Intermediate is a high-quality oil that is easily refined. The price of WTI is often reported on in news reports on the oil industry and oil commodities, together with Brent Crude Oil which originates from the North Sea. Oil futures contracts on the New York Mercantile Exchange (NYMEX) use West Texas Intermediate as an underlying commodity.
The Australian dollar to Canadian dollar exchange rate has the abbreviation CAD. The Australian dollar is often known as the “Aussie”, while the Canadian dollar has been nicknamed the “Loonie” after the bird depicted on the C$1 coin. The Australian dollar is the 5th most-traded currency in the world, and is involved in 6.9% of all daily forex trades. The Canadian dollar is the 6th most popular currency, and makes up one side in 5.1% of all daily trades.
Both the Australian dollar and Canadian dollar are commodity-correlated currencies, and along with the New Zealand dollar make up the commodity trio, or commodity bloc.
The movement of particular commodity prices can have a significant impact upon the pairing. The Australian economy is heavily reliant upon iron ore exports, so changes in the price of this can push AUD/CAD higher or lower. Canada is one of the world's largest oil exporters, so changes in the crude market can also drive price action.
USD/CAD is the abbreviation for the US Dollar to Canadian dollar exchange rate. The pair accounts for 4.3% - $218 billion - of all daily forex trades. The US Dollar is the most popular currency to trade, while the Canadian dollar is the 6th most popular. CAD, also known as the “Loonie”, after the bird depicted upon the C$1 coin, accounts for 4.6% of daily forex activity.
The majority of Canadian dollars are exchanged for US Dollars. Canada is the second-largest trade partner for the US; in 2017 the US exported $341.2 billion worth of goods to Canada and imported $332.8 billion. The two nations and Mexico are bound by the North American Free Trade Agreement (NAFTA), although its future is uncertain.
Canada is one of the world's largest oil producers, so the price of crude on the international market has a significant impact upon the USD/CAD exchange rate. In times of high risk-appetite USD/CAD weakens, while low risk-appetite pushes the pairing higher.
EUR/CAD is the abbreviation for the euro to Canadian dollar exchange rate. The pairing accounts for around 0.3% of daily forex trading across the globe; the equivalent of US$14 billion.
The euro is the currency of the 19-nation Eurozone, which is overseen by the European Central Bank. The euro, also known as the common currency, the single currency, or the single unit, has an inverse correlation with the US Dollar. However, the impact of this upon the euro is lessened when trading against the Canadian dollar, which also often moves inversely to the dollar.
The Canadian dollar is highly-sensitive to the price of crude oil, as this is Canada's main export. When oil prices fall, the outlook for the Canadian economy weakens, pushing the EUR/CAD exchange rate higher. When oil prices rise, the opposite happens.
Euro strength is influenced by the economic health of the Eurozone, which experienced a debt crisis in 2012 that saw several of its member states requiring bailouts.
The UK 100 is a blue-chip index of the largest 100 companies on the London Stock Exchange in terms of market capitalisation. Companies are only included if they meet relevant size and liquidity requirements.
The index was launched on 3rd January 1984, with a base date of 30th December 1983 and a base level of 1,000 points.
In terms of weighting, the three largest sectors of the UK 100 as of H2 2018 are Oil & Gas (16.56%), Banks (12.70%), and Personal & Household Goods (12.37%).
Traditionally the index has lagged its peers, such as the larger FTSE 250 and the US S&P 500. The index fluctuates in response to market risk sentiment and the strength of the pound Sterling. The UK 100 contains many international companies who report their earnings in other currencies, so a stronger pound weakens company profits.
Because of this, the UK 100 is also considered to be an unreliable indicator of the health of the UK economy because of its large international component.
Copper is found in ore deposits around the world and top producers include Chile, China, Peru and the US. It was the first metal to be used by humans and remains essential for a variety of uses: it is the world's third most widely used metal, after iron and aluminium.
Copper is priced in USD per lb. it's all-time high was $4.58, which it reached in February 2011. Copper hit a record low of $1.94 in January 2016.
Like silver and gold, it is malleable and a good conductor of electricity, however it is also relatively inexpensive which makes it ideal for industrial applications such as wiring, plumbing and circuitry.
The price of copper is influenced by a number of factors including the strength of the US Dollar, demand from China and extraction costs. However, the energy-intensive refining process mean it is also susceptible to changes in oil prices.
Instability in the political climate of key countries where copper is mined can also affect the price.

Rice is priced in USD per hundredweight (CWT). In April 2008 prices of the grain peaked at $24.46/CWT, while in February 1982 they hit a low of $0.75/CWT.
China produces the bulk of the world's rice. India, Indonesia, Bangladesh, Vietnam, and Thailand are also big producers.
Rice prices are affected by many factors, including stock levels, the pace of demand growth, and changes in government spending on agriculture. One of the biggest drivers of volatility is crude oil prices - rising prices push up the cost of production and transportation.
Rice futures allow you to speculate on, or hedge against, changes in the price of rice. Futures rollover on the fourth Friday of February, April, June, August, October, and December.
Soybeans are a “soft” commodity - referring to those that are grown and not mined. It is one of the world's most important legumes and is an essential source of protein. It is used extensively in cooking, both soybeans and soy oil, and is also used for animal feed in the form of soy meal.
Soybean is priced in USD per bushel. In July 2012, Soybeans reached an all-time high of $1790, while it reached a low of $208 in September 1959.
The US are the biggest producers of Soybeans, followed by Brazil, Argentina and Paraguay. Together they account for 85% of total production, and 94% of total exports. China is the biggest importer of soybeans.

Coffee is a “soft” commodity - referring to those that are grown rather than mined. It is the world's second-most popular commodity, behind only crude oil. The market is worth around $100 billion.
Over 50 countries worldwide grow coffee, with around two-thirds of the global supply produced in the Americas. Brazil, Vietnam, and Colombia are the three largest producers.
Coffee is priced in USD per lb. It hit a record high of $339.86/lb during April 1977, while the lowest price on record is $42.50/lb in October 2001.
Coffee is a highly-traded commodity that is often bought by speculators, so risk appetite has a strong effect on prices. Around half of the coffee produced on the globe is bought by just four companies: Kraft, P&G, Sara Lee, and Nestle, so changes in the fortunes of these companies can also impact prices.
Coffee futures allow you to speculate on, or hedge against, changes in the price of coffee. Futures rollover on the second Friday of February, April, June, August, and November.
USD/NOK is the symbol for the US Dollar to Norwegian krone exchange rate. The US Dollar is by far the world's most-traded currency, accounting for 87% of all over-the-counter FX each day - $4.4 trillion.
The krone is the 13th most-trade currency, accounting for 1.7% of all daily forex activity. Around $US48 billion worth of USD/NOK - 0.9% of the total daily volume - is traded each day.
The US Dollar is not only the most ubiquitous currency on the globe, but also a safe-haven asset. In times of market uncertainty traders withdraw from riskier assets into stable USD.
The Norwegian economy is strongly-reliant upon crude oil and natural gas; the nation is one of the 5 top exporters of gas and oil, with the sector accounting for 22% of Norwegian GDP and 67% of the country's exports. USD/NOK therefore benefits doubly in times of low risk-appetite.
The EU is an important trade partner for Norway, accounting for 72% of its trade. Eurozone economic data can therefore have an impact upon NOK.
The euro to Norwegian krone exchange rate has the acronym EUR/NOK. The euro is the 2nd most-traded currency on the planet, making up one side of 31% of daily trades. The krone is the 13th most-trade currency, accounting for 1.7% of all daily forex activity. Around $US28 billion worth of EUR/NOK - 0.6% of the total daily FX volume - is traded each day.

Brent Crude is a physically and financially traded oil market based around the North Sea of Northwest Europe. In finance and trading the term refers to the price of the ICE (Intercontinental Exchange) or Brent Crude Oil futures contracts. The original Brent Crude referred only to a trading classification of sweet light crude oil extracted from the Brent oilfield in the North Sea.

The current Brent Crude blend consists of crude oil produced from the Forties, Oseberg, Ekofisk, and Troll oil fields.
Why is Brent crude so important?
Brent Crude is important to the financial and trading domains as it is a leading global price benchmark for Atlantic basin crude oils. It is used to set the price of two-thirds of the world's internationally traded crude oil supplies. It is one of the two main benchmark prices for purchases of oil worldwide, the other being West Texas Intermediate (WTI).
The Brent Crude oil marker is also known as Brent Blend, London Brent, and Brent petroleum.

The pair is highly sensitive to changes in market risk-appetite, as the Canadian dollar is a commodity-correlated currency and the Japanese yen is a safe-haven currency.
The Canadian dollar is highly sensitive to changes in the price of crude oil - Canada's primary export. In turn, crude prices often respond to market appetite for risk, so the strength of the CAD/JPY exchange rate is largely dictated by whether traders are feeling optimistic or pessimistic over global conditions.
In times of market uncertainty, appetite for the safe-haven Japanese yen can increase sharply. However, the yen is often softened by the Bank of Japan's ultra-loose monetary stimulus package, which includes quantitative easing and negative interest rates.
The Australian dollar to Canadian dollar exchange rate has the abbreviation CAD. The Australian dollar is often known as the “Aussie”, while the Canadian dollar has been nicknamed the “Loonie” after the bird depicted on the C$1 coin. The Australian dollar is the 5th most-traded currency in the world, and is involved in 6.9% of all daily forex trades. The Canadian dollar is the 6th most popular currency, and makes up one side in 5.1% of all daily trades.
Both the Australian dollar and Canadian dollar are commodity-correlated currencies, and along with the New Zealand dollar make up the commodity trio, or commodity bloc.
The movement of particular commodity prices can have a significant impact upon the pairing. The Australian economy is heavily reliant upon iron ore exports, so changes in the price of this can push AUD/CAD higher or lower. Canada is one of the world's largest oil exporters, so changes in the crude market can also drive price action.
Copper is found in ore deposits around the world and top producers include Chile, China, Peru and the US. It was the first metal to be used by humans and remains essential for a variety of uses: it is the world's third most widely used metal, after iron and aluminium.
Copper is priced in USD per lb. it's all-time high was $4.58, which it reached in February 2011. Copper hit a record low of $1.94 in January 2016.
Like silver and gold, it is malleable and a good conductor of electricity, however it is also relatively inexpensive which makes it ideal for industrial applications such as wiring, plumbing and circuitry.
The price of copper is influenced by a number of factors including the strength of the US Dollar, demand from China and extraction costs. However, the energy-intensive refining process mean it is also susceptible to changes in oil prices.
Instability in the political climate of key countries where copper is mined can also affect the price.
Coffee is a “soft” commodity - referring to those that are grown rather than mined. It is the world's second-most popular commodity, behind only crude oil. The market is worth around $100 billion.
Over 50 countries worldwide grow coffee, with around two-thirds of the global supply produced in the Americas. Brazil, Vietnam, and Colombia are the three largest producers.
Coffee is priced in USD per lb. It hit a record high of $339.86/lb during April 1977, while the lowest price on record is $42.50/lb in October 2001.
Coffee is a highly-traded commodity that is often bought by speculators, so risk appetite has a strong effect on prices. Around half of the coffee produced on the globe is bought by just four companies: Kraft, P&G, Sara Lee, and Nestle, so changes in the fortunes of these companies can also impact prices.
Coffee futures allow you to speculate on, or hedge against, changes in the price of coffee. Futures rollover on the second Friday of February, April, June, August, and November.
Brent Crude is a physically and financially traded oil market based around the North Sea of Northwest Europe. In finance and trading the term refers to the price of the ICE (Intercontinental Exchange) or Brent Crude Oil futures contracts. The original Brent Crude referred only to a trading classification of sweet light crude oil extracted from the Brent oilfield in the North Sea. Additional oil blends from other oil fields have been added to the trade classification as time went by. The current Brent Crude blend consists of crude oil produced from the Forties, Oseberg, Ekofisk, and Troll oil fields.
Why is Brent crude so important?
Brent Crude is important to the financial and trading domains as it is a leading global price benchmark for Atlantic basin crude oils. It is used to set the price of two-thirds of the world's internationally traded crude oil supplies. It is one of the two main benchmark prices for purchases of oil worldwide, the other being West Texas Intermediate (WTI).
The Brent Crude oil marker is also known as Brent Blend, London Brent, and Brent petroleum.
Heating Oil is a low-viscosity petroleum product derived from crude oil. Around 25% of the yield of crude oil is devoted to heating oil, the second most after gasoline products. As a result, prices often closely follow those of WTI crude.
It is priced in USD per gallon, and has a historic high of $3.32 in April 2011. The record low was $0.87 in January 2016.
Heating oil is used as a fuel for furnaces and boilers to heat homes and businesses. It is especially popular in the British Isles and the North-eastern US. As a result, demand fluctuates seasonally, peaking in the colder months between October and March.
Price is, as a result, also affected by cold weather. Other factors affecting price include the price of alternative heating options, energy efficiency and insulation, refining costs and government regulations.
Heating Oil futures allow you to speculate on, or hedge against, changes in the price of Heating Oil. Futures rollover on the third Friday of every month.
Energy Select Sector SPDR Fund (XLE) tracks US energy companies within the S&P 500. This asset uses the Energy Select Sector Index as its tracking benchmark. The ETF is offers concentrated exposure to oil and gas industry giants, as the S&P500 favours large-caps. Nevertheless, it is fairly representative of the whole energy market.
Just a few holdings make up a big part of the portfolio, and there are only 31 holdings in total. Top holdings for the benchmark index include Exxon Mobil Corp, Chevron Corp and ConocoPhillips.
The pound Sterling to Canadian dollar exchange rate is identified by the abbreviation GBP/CAD. GBP is the 4th most-traded currency, accounting for 13% of all daily trades; US$649 billion worth.
Recently, political factors have seen their influence over the pound grow. This is because the Brexit referendum, which resulted in the UK voting to leave the EU, has created significant uncertainty regarding the UK economic outlook. Signs of upheaval in government as Downing Street tries to negotiate a Brexit deal that pleases all sides of the debate, as well as fears that the UK will crash out of the EU with no deal in place, weigh heavily on Sterling.
The Canadian dollar is highly-sensitive to changes in the US Dollar, as well as the price of crude oil, as this is Canada's main export. When oil prices fall, the outlook for the Canadian economy weakens, pushing the GBP/CAD exchange rate higher. When oil prices rise, the opposite happens.
EUR/CAD is the abbreviation for the euro to Canadian dollar exchange rate. The pairing accounts for around 0.3% of daily forex trading across the globe; the equivalent of US$14 billion.
The euro is the currency of the 19-nation Eurozone, which is overseen by the European Central Bank. The euro, also known as the common currency, the single currency, or the single unit, has an inverse correlation with the US Dollar. However, the impact of this upon the euro is lessened when trading against the Canadian dollar, which also often moves inversely to the dollar.
The Canadian dollar is highly-sensitive to the price of crude oil, as this is Canada's main export. When oil prices fall, the outlook for the Canadian economy weakens, pushing the EUR/CAD exchange rate higher. When oil prices rise, the opposite happens.
Euro strength is influenced by the economic health of the Eurozone, which experienced a debt crisis in 2012 that saw several of its member states requiring bailouts.
The CAC 40, also known as the France 40, is a blue-chip index and stock market barometer comprising of the 40 companies listed in Paris with the highest liquidity and free-float market capitalisation. It is the most-traded index administered by Euronext.

Oil & Gas is the third-biggest sector, with a weighting of just under 12%. Healthcare and Banks are the fourth and fifth largest sectors respectively. Companies are limited to a 15% weighting.
CAC 40 index futures allow you to speculate on, or hedge against, changes in the price of major French stocks. Futures rollover on the second Friday of each month.
The euro to Norwegian krone exchange rate has the acronym EUR/NOK. The euro is the 2nd most-traded currency on the planet, making up one side of 31% of daily trades. The krone is the 13th most-trade currency, accounting for 1.7% of all daily forex activity. Around $US28 billion worth of EUR/NOK - 0.6% of the total daily FX volume - is traded each day.
The euro is the currency of the Eurozone, which is overseen by the European Central Bank. The euro, also known as the common currency, the single currency, or the single unit, has an inverse correlation with the US Dollar.
The Norwegian economy is strongly-reliant upon crude oil and natural gas; the nation is one of the 5 top exporters of gas and oil, with the sector accounting for 22% of Norwegian GDP and 67% of the country's exports. The EU is an important trade partner for Norway, accounting for 72% of its trade. Eurozone economic data can therefore have an impact upon NOK as well as EUR.
The STOXX Europe 50 Index, also known simply as the Europe 50, is Europe's blue-chip index, comprising of 50 stocks from 17 countries; Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

A 15% weighting cap is in operation to ensure that no single component can dominate the index.
Italy 40 futures allow you to speculate on, or hedge against, changes in the price of major stocks on the Italian stock market. Futures rollover on the 2nd Friday of March, June, September, and December.
Crude Oil, also known as West Texas Intermediate (WTI), is a light, sweet crude that acts as benchmark for oil prices in the US.
Crude Oil is priced in USD per barrel. It reached a historic high of $145.31 in July 2008 and saw a record low of $1.17 in February 1946.
WTI contains less sulphur than Brent Crude (which acts as a benchmark for oil prices in Europe and the Middle East), which means it demands a premium price. Both WTI and Brent are light, sweet oils that are ideal for refining into gasoline.
It is produced, refined and consumed in North America, and is mostly sourced in Texas - which is where the name originates - as well as in Louisiana and North Dakota.
WTI price is sensitive to factors that impact the general price of oil, as well as geopolitical and economic events and natural disasters in the Midwest and Gulf Coast regions.
NZD/CAD is the abbreviation for the New Zealand dollar to Canadian dollar exchange rate. The New Zealand dollar is the 10th most-traded currency, accounting for 2.1% of daily transactions. US$104 billion worth of NZD is traded daily. The Canadian dollar is the 6th most-traded currency, involved in 5.1% of all daily transactions.
The New Zealand dollar is highly-sensitive to commodity prices. Dairy is the country's main industry; when dairy prices fall, the outlook for the New Zealand economy weakens, pushing the NZD/CAD rate lower. When dairy prices rise, the opposite happens.
The Canadian dollar is heavily-exposed to changes in the price of crude oil - Canada's primary export. Both currencies are inversely correlated with the US Dollar, so even in times of risk movement in the NZD/CAD is more driven by fundamental factors.
The Canadian dollar is more exposed because the USA is Canada's largest trading partner by far.
Natural gas is a found deep underground, alongside coal and other fossil fuel deposits. It is extensively used in the US, accounting for 25% of US energy consumption. The gas primarily consists of methane.
It is priced in USD per British thermal units (mmBtu). The highest price recorded for Natural gas was $15.30 in December 2005, a record low of $1.02 was seen in January 1992.
Natural gas is used as a source of energy generation, especially for heating and cooling systems. It is often preferred to goal or oil as it produces less greenhouse gases than other fossil fuels.
Just ten countries account for close to 80% of the proven natural gas supplies in the world, with Russia sitting on 25% of total reserves. The Middle East is home to several the remaining top producers, excluding the US.
Gas futures allow you to speculate on, or hedge against, changes in the price of gas.

Rice is a “soft” commodity - referring to those that are grown and not mined - and is the third most-farmed grain in the world, behind cotton and wheat. It is a food staple for billions of people, spread throughout Asia, the Middle East, and Latin America.
Rice is priced in USD per hundredweight (CWT). In April 2008 prices of the grain peaked at $24.46/CWT, while in February 1982 they hit a low of $0.75/CWT.
China produces the bulk of the world's rice. India, Indonesia, Bangladesh, Vietnam, and Thailand are also big producers.
Rice prices are affected by many factors, including stock levels, the pace of demand growth, and changes in government spending on agriculture. One of the biggest drivers of volatility is crude oil prices - rising prices push up the cost of production and transportation.
Rice futures allow you to speculate on, or hedge against, changes in the price of rice. Futures rollover on the fourth Friday of February, April, June, August, October, and December.
Soybeans are a “soft” commodity - referring to those that are grown and not mined. It is one of the world's most important legumes and is an essential source of protein. It is used extensively in cooking, both soybeans and soy oil, and is also used for animal feed in the form of soy meal.
Soybean is priced in USD per bushel. In July 2012, Soybeans reached an all-time high of $1790, while it reached a low of $208 in September 1959.
The US are the biggest producers of Soybeans, followed by Brazil, Argentina and Paraguay. Together they account for 85% of total production, and 94% of total exports. China is the biggest importer of soybeans.
The price of soybeans is affected by a number of factors, including growing conditions, the demand for biofuel and the strength of USD.
Soybean futures allow you to speculate on, or hedge against, changes in the price of soybeans. Futures rollover on the fourth Friday of February, April, June, October, and December.

The United States Oil Fund (USO) is an ETF that aims to track the daily price movements of WTI Crude Oil. USO's Benchmark is the near-month crude oil futures contract traded on the NYMEX. The Crude Oil contract is WTI light, sweet crude delivered to Cushing Oklahoma.
This ETF is a good way to get commodity exposure without using a futures account and offers more options for traders such as intraday pricing and limit/stop orders.
The US Dollar to Indian rupee exchange rate is an exotic currency pair known by the abbreviation USD/INR. The US Dollar is by far the world's most-traded currency, accounting for 87% of all over-the-counter FX each day - $4.4 trillion. The rupee is the 18th most-active currency, accounting for 1.1% of daily transactions.
The US Dollar is not only the most ubiquitous currency on the globe, but also a safe-haven asset. As an emerging market currency, the rupee is popular in times of confidence and is sold when volatility increases. As a result of rising global trade tensions, INR weakened to record lows in the second half of 2018.
India is a net oil importer, so rising crude prices increase import costs, widening the current account deficit. Foreign direct investment (FDI) is key for the Indian economy, which benefits from overseas businesses looking to take advantage of the tax exemptions and lower labour costs.
The US Dollar to Mexican peso exchange rate is identified by the abbreviation USD/MXN. The US Dollar is by far the world's most-traded currency, accounting for 87% of all over-the-counter FX each day - $4.4 trillion.
The Mexican peso is the 11th most-traded currency, accounting for 1.9% of daily transactions.
The US Dollar is not only the most ubiquitous currency on the globe, but also a safe-haven asset. In times of market uncertainty traders withdraw from riskier assets into stable USD. It is the most popular reserve currency
MXN is tied to the price of crude oil because of Mexico's high reserves, which the government uses as collateral when borrowing to fund spending. 10% of Mexico's GDP comes from oil production, so when prices fall it not only pushes up borrowing costs, but also weakens the outlook for growth.
Cross-border trade with the US also generates strong demand for pesos. The currency therefore weakens when trade comes under threat.
West Texas Intermediate or WTI is a benchmark type of oil that is central to commodities trading. These benchmarks indicate quality and also the source of the oil. The three dominant benchmarks for oil are WTI, Brent Crude and Dubai/Oman. These are similar indicators as Scottish and Norwegian might be for smoked salmon, for example.
What is the difference between West Texas Intermediate and Brent crude?
The different benchmarks for oil come from different regions and have different chemical compositions. They have what are called 'quality spreads' and 'location spreads' which affect price differences.
What is West Texas Intermediate Used For?
West Texas Intermediate is a high-quality oil that is easily refined. The price of WTI is often reported on in news reports on the oil industry and oil commodities, together with Brent Crude Oil which originates from the North Sea. Oil futures contracts on the New York Mercantile Exchange (NYMEX) use West Texas Intermediate as an underlying commodity.
USD/CAD is the abbreviation for the US Dollar to Canadian dollar exchange rate. The pair accounts for 4.3% - $218 billion - of all daily forex trades. The US Dollar is the most popular currency to trade, while the Canadian dollar is the 6th most popular. CAD, also known as the “Loonie”, after the bird depicted upon the C$1 coin, accounts for 4.6% of daily forex activity.
The majority of Canadian dollars are exchanged for US Dollars. Canada is the second-largest trade partner for the US; in 2017 the US exported $341.2 billion worth of goods to Canada and imported $332.8 billion. The two nations and Mexico are bound by the North American Free Trade Agreement (NAFTA), although its future is uncertain.
Canada is one of the world's largest oil producers, so the price of crude on the international market has a significant impact upon the USD/CAD exchange rate. In times of high risk-appetite USD/CAD weakens, while low risk-appetite pushes the pairing higher.
The UK 100 is a blue-chip index of the largest 100 companies on the London Stock Exchange in terms of market capitalisation. Companies are only included if they meet relevant size and liquidity requirements.
The index was launched on 3rd January 1984, with a base date of 30th December 1983 and a base level of 1,000 points.
In terms of weighting, the three largest sectors of the UK 100 as of H2 2018 are Oil & Gas (16.56%), Banks (12.70%), and Personal & Household Goods (12.37%).
Traditionally the index has lagged its peers, such as the larger FTSE 250 and the US S&P 500. The index fluctuates in response to market risk sentiment and the strength of the pound Sterling. The UK 100 contains many international companies who report their earnings in other currencies, so a stronger pound weakens company profits.
Because of this, the UK 100 is also considered to be an unreliable indicator of the health of the UK economy because of its large international component.
USD/NOK is the symbol for the US Dollar to Norwegian krone exchange rate. The US Dollar is by far the world's most-traded currency, accounting for 87% of all over-the-counter FX each day - $4.4 trillion.
The krone is the 13th most-trade currency, accounting for 1.7% of all daily forex activity. Around $US48 billion worth of USD/NOK - 0.9% of the total daily volume - is traded each day.
The US Dollar is not only the most ubiquitous currency on the globe, but also a safe-haven asset. In times of market uncertainty traders withdraw from riskier assets into stable USD.
The Norwegian economy is strongly-reliant upon crude oil and natural gas; the nation is one of the 5 top exporters of gas and oil, with the sector accounting for 22% of Norwegian GDP and 67% of the country's exports. USD/NOK therefore benefits doubly in times of low risk-appetite.
The EU is an important trade partner for Norway, accounting for 72% of its trade. Eurozone economic data can therefore have an impact upon NOK.
