How do currency markets work?
Unlike shares or commodities, forex trading does not take place on exchanges but directly between two parties, in an over-the-counter (OTC) market. The forex market is run by a global network of banks, spread across four major forex trading centres in different time zones: London, New York, Sydney and Tokyo. Because there is no central location, you can trade forex 24 hours a day.
There are three different types of forex market:
- Spot forex market: the physical exchange of a currency pair, which takes place at the exact point the trade is settled – ie ‘on the spot’ – or within a short period of time
- Forward forex market: a contract is agreed to buy or sell a set amount of a currency at a specified price, to be settled at a set date in the future or within a range of future dates
- Future forex market: a contract is agreed to buy or sell a set amount of a given currency at a set price and date in the future. Unlike forwards, a futures contract is legally binding
Most traders speculating on forex prices will not plan to take delivery of the currency itself; instead they make exchange rate predictions to take advantage of price movements in the market.
What is a base currency?
A base currency is the first currency listed in a forex pair, while the second currency is called the quote currency. Forex trading always involves selling one currency in order to buy another, which is why it is quoted in pairs – the price of a forex pair is how much one unit of the base currency is worth in the quote currency.
Each currency in the pair is listed as a three-letter code, which tends to be formed of two letters that stand for the region, and one standing for the currency itself. For example, GBP/USD is a currency pair that involves buying the Great British pound and selling the US dollar.
To keep things ordered, most providers split pairs into the following categories:
- Major pairs. Seven currencies that make up 80% of global forex trading. Includes EUR/USD, USD/JPY, GBP/USD and USD/CHF
- Minor pairs. Less frequently traded, these often feature major currencies against each other instead of the US dollar. Includes: EUR/GBP, EUR/CHF, GBP/JPY
- Exotics. A major currency against one from a small or emerging economy. Includes: USD/PLN, GBP/MXN, EUR/CZK
- Regional pairs. Pairs classified by region – such as Scandinavia or Australasia. Includes: EUR/NOK, AUD/NZD, AUG/SGD
What moves the forex market?
The forex market is made up of currencies from all over the world, which can make exchange rate predictions difficult as there are many factors that could contribute to price movements. However, like most financial markets, forex is primarily driven by the forces of supply and demand, and it is important to gain an understanding of the influences that drives price fluctuations here.
Supply is controlled by central banks, who can announce measures that will have a significant effect on their currency’s price. Quantitative easing, for instance, involves injecting more money into an economy, and can cause its currency’s price to drop.
Commercial banks and other investors tend to want to put their capital into economies that have a strong outlook. So, if a positive piece of news hits the markets about a certain region, it will encourage investment and increase demand for that region’s currency.
Unless there is a parallel increase in supply for the currency, the disparity between supply and demand will cause its price to increase. Similarly, a piece of negative news can cause investment to decrease and lower a currency’s price. This is why currencies tend to reflect the reported economic health of the region they represent.
Market sentiment, which is often in reaction to the news, can also play a major role in driving currency prices. If traders believe that a currency is headed in a certain direction, they will trade accordingly and may convince others to follow suit, increasing or decreasing demand.
