5 Factors that Influence Exchange Rates

5 Factors that Influence Exchange Rates

What is an exchange rate and how it is determined?

The exchange rate is the price or value of a determinate currency in relation to another currency (usually but not exclusively, the American dollar). The exchange rate is mostly determined by market forces in the foreign exchange market, however, this depends on the country’s current exchange rate structure and, as we’re going to explain in this article, other factors.

Floating exchange rates are currently the most common exchange rate structure in the world, however in reality most countries have a managed float system since most countries are likely to use their foreign currency reserves to affect the rate. Let’s take a look at the factors that are most likely to impact a country’s exchange rate.

1 The Interest Rate

The interest rate is simply the amount charged, expressed as a percentage of the loan, by the lender to a borrower. From a macroeconomic point of view, the interest rate we are talking about is the current interest rate, which is the interest rate at which banks can borrow money from the central bank. The current interest rate itself is a powerful monetary policy tool and is set by the central bank. The reason why it’s so powerful is because it affects diverse economic variables and the economic agents expectative.  In this particular case, a differential in interest rates between two countries makes the country with the highest one relatively more attractive for foreign investors, increasing the demand for the local currency and rising the exchange rate. Naturally, other economic variables may come into play and may affect the influence of the interest rate in the foreign exchange rate. A country like Venezuela, for example, could increase its current interest rate but would not increase its attractiveness to foreign investors significantly since there are other factors that affects this degree of attractiveness.

This relationship is not always so neat and obvious. For example, the United States has managed to keep favorable exchange rates while maintaining interest rates near zero. The reason for this is that the dollar, unlike other currencies, is the world’s reserve currency.

It’s also worth adding thatthe interest rate also affects inflation and the state of the economy in general. An increase in the interest rate makes it more attractive for individuals to save money making the economy slower which decreases inflation, a move that can potentially be detrimental to the degree of attractiveness of an economy.

2 Inflation Levels

The inflation is the ongoing increase of general price levels in an economy, affecting the purchase power, the price levels and the economic growth. Its complex relationship with the current interest rate puzzles policy makers and drives them to try to make decisions that balance both. An increase or decrease of inflation is not necessarily negative for the state of the economy in general, but an inflation rate that is too high ortoo low can be detrimental to the economy, affecting the investor’s expectative and their willingness to hold on to a determinate currency.

For example, a high inflation rate is usually a sign of an unstable economy, which makes less attractive for investors to hold its currency. On the other hand, a low inflation rate can affect consumption and economic growth significantly. One of the most famous cases of this is Japan, which kept very low inflation rates for a long period which affected its growth and employment levels.

3 Public Debt

The public (or national) debt is the amount of money that the government owes to local and foreign lenders, these financial borrowings are usually made to cover the budget deficit.

The amount of public debt is related to the risk of defaulting, and the perception of the investors in a specific country. A high public debt can a have a negative impact on the exchange rate depending on the country’s plan to deal with it. If the country deals with it by printing money this will cause an increase in inflation (which has a direct influence in exchange rates) and affect the credibility of the central bank. This is not always true since there are countries with high levels of public debt (like the United States) that still manage to maintain debt without affecting its currency value significantly

So it can be concluded that while debt levels may impact a country’s exchange rate, the government’s level of credibility is just as important.

4 Government Action

The way a government behaves has a direct impact on many economic factors.

For example, if the government decides to use its foreign currency reserves level to aid its currency it might affect the exchange rate positively. So if a country decides to sell its foreign currency reserves this will decrease the amount of local currency available in the market, increasing its value. Conversely, a country can buy huge quantities of foreign currency putting more local currency in circulation, decreasing its value.

This method, as a monetary policy instrument, is very limited since the government capacity to buy and sell is limited.

Other government actions can also affect exchange rate, in general, bad or questionable policies can affect the willingness of investors to hold currencies.

5 Speculation

Investors tend to speculate when a country’s exchange rate has a wrong value, selling or buying it with the intention of obtaining an economic profit from it. So the speculators might buy the currency when its value is low and sell it when it gains value. This might, or not, have a stabilizing effect on the exchange rate.

For example, the speculators can decide to sell the currency in masse causing a decrease in the currency value, conversely they might decide to buy the currency, increasing its value.

The effects of speculation (and the degree of its influence) and whether it is positive or negative is currently debated by economists.

It’s Not That Simple

In general, the five factors listed above to impact a country’s exchange rate, but when taken together, it’s often difficult to measure the impact of any one factor. Still, if you’re looking to profit from exchange rate fluctuations, it’s important to understand these underlying factors and to consider them carefully before placing any trades.
