Uses of the Forex Markets

 

Forex for Hedging

Companies doing business in foreign countries are at risk due to fluctuations in currency values when they buy or sell goods and services outside of their domestic market. Foreign exchange markets provide a way to hedge currency risk by fixing a rate at which the transaction will be completed.

To accomplish this, a trader can buy or sell currencies in the forward or swap markets in advance, which locks in an exchange rate. For example, imagine that a company plans to sell U.S.-made blenders in Europe when the exchange rate between the euro and the dollar (EUR/USD) is €1 to $1 at parity.

The blender costs $100 to manufacture, and the U.S. firm plans to sell it for €150—which is competitive with other blenders that were made in Europe. If this plan is successful, then the company will make $50 in profit per sale because the EUR/USD exchange rate is even. Unfortunately, the U.S. dollar begins to rise in value vs. the euro until the EUR/USD exchange rate is 0.80, which means it now costs $0.80 to buy €1.00.

The problem facing the company is that while it still costs $100 to make the blender, the company can only sell the product at the competitive price of €150—which, when translated back into dollars, is only $120 (€150 × 0.80 = $120). A stronger dollar resulted in a much smaller profit than expected.

The blender company could have reduced this risk by short selling the euro and buying the U.S. dollar when they were at parity. That way, if the U.S. dollar rose in value, then the profits from the trade would offset the reduced profit from the sale of blenders. If the U.S. dollar fell in value, then the more favorable exchange rate would increase the profit from the sale of blenders, which offsets the losses in the trade.

Hedging of this kind can be done in the currency futures market. The advantage for the trader is that futures contracts are standardized and cleared by a central authority. However, currency futures may be less liquid than the forwards markets, which are decentralized and exist within the interbank system throughout the world.

Forex for Speculation

Factors like interest rates, trade flows, tourism, economic strength, and geopolitical risk affect the supply and demand for currencies, creating daily volatility in the forex markets. An opportunity exists to profit from changes that may increase or reduce one currency’s value compared to another. A forecast that one currency will weaken is essentially the same as assuming that the other currency in the pair will strengthen because currencies are traded as pairs.

Imagine a trader who expects interest rates to rise in the United States compared to Australia while the exchange rate between the two currencies (AUD/USD) is 0.71 (i.e., it takes $0.71 USD to buy $1.00 AUD). The trader believes higher U.S. interest rates will increase demand for USD, and the AUD/USD exchange rate therefore will fall because it will require fewer, stronger USDs to buy an AUD.

Assume that the trader is correct and interest rates rise, which decreases the AUD/USD exchange rate to 0.50. This means that it requires $0.50 USD to buy $1.00 AUD. If the investor had shorted the AUD and went long on the USD, then they would have profited from the change in value.
