Interest Rates - Importance to Forex
Interest rates play the most important role in moving the prices of currencies in the foreign exchange market. As the institutions that set interest rates, central banks are therefore the most influential actors. Interest rates dictate flows of investment. Since currencies are the representations of a country’s economy, differences in interest rates affect the relative worth of currencies in relation to one another. When central banks change interest rates they cause the forex market to experience movement and volatility. In the realm of Forex trading, accurate speculation of central banks’ actions can enhance the trader's chances for a successful trade.
Interest Rates Dictate Investment
Interest rates can be simply defined as the amount of money a borrower must pay to a lender in order to hold their money. In a simple representation of the foreign exchange market, the lender is an investor holding cash or assets and the borrower is a bank inside a particular country. The lender (investor) provides money to the borrower (the bank) and will receive, after a specific time period, interest in conjunction with the original sum he or she put in. Typically, interest is applied as an annual rate or percentage of the amount being lent. In forex trading interest is credited on a daily basis.
A simple example:
A US investor, Jane, wants to place 100 dollars into a savings account with either a domestic or a foreign bank. The US bank’s interest rate is 5.25%. In Japan, the interest rate for a savings account is 0.25% and in New Zealand it is 7.25%. In considering the best investment after a year, Jane can get back $105.25 investing in the US, $100.25 in Japan, and $107.25 in New Zealand. Opening an account and “lending” money to a New Zealand bank is the investment option that achieves the biggest return for Jane.
Jane’s investment decision shows that higher interest rates attract capital. As a result central banks may attempt to draw foreign investment to their countries through higher interest rates.
How Interest Rates Play a Role in the Currency Markets
An increase in interest rates encourages traders to invest within that market and causes the demand for the currency to rise. As demand rises, the currency becomes scarcer and consequently more valuable. Investors are drawn to the currency, causing it to appreciate, because they will gain a higher yield on their investments, as in the Jane example. In order to purchase the country's assets (stocks or bonds), Jane will have to convert her domestic currency to the target country's currency also increasing demand. Conversely, a fall in interest rates dissuades investors from purchasing assets in that economy, as the return on their investment is now smaller. The economy's currency will depreciate as a result of the weaker demand
The Role of Central Banks
Central Banks Set Interest Rates
Bank of England Since central banks, also known as reserve banks, play the crucial role of setting interest rates they need to be followed and studied by a fundamental (and even technical) Forex trader. Central banks want to achieve financial stability of their currency (i.e. battle inflation) and maintain overall economic growth in their country. Their primary responsibility is to oversee the monetary policy of a particular country or group of countries (in the case of the European Union). Monetary policy refers to the various efforts made to effectively control and manage the amount of money circulating within a nation. Skilled investors are able to properly identify which currency will experience an increase in interest rates based upon a central bank’s statements and incoming financial data. Those investors that are correct in their speculations can predict how the respective currencies should move, and as a result should be able to take the proper long or short positions.
Central Bank’s Role in Fighting Inflation
Central banks act in ways to lessen the effects of inflation on an economy. Inflation refers to a rise in price levels which causes a fall in the purchasing power of a currency. Inflation accounts for an entire basket of goods and services, not just an increase in the price of one item. Monitoring prices of a particular basket is known as indexing and provides a reliable method of tracking inflationary movement.
Inflation’s effects can be felt on just about everyone within a society regardless of whether one engages in trading or not. At times of high inflation, employees will demand more money for their work as the previous hourly wage no longer reflects the same value. In order to pay their employees more, businesses have to raise their prices so that they can also manage to raise the wages of its employees.
Inflation and Oil (Example)
Inflation Interestingly, inflation can be set off by the increase in price of just one crucial item (food or energy) as well. An example of a volatile commodity that can cause inflation is oil. An increase in the price of oil would cause many other items that use it as an input in the production process (such as gasoline) to also increase in price and therefore begin the inflationary process. Inflation poses a problem to the population because it erodes people’s wealth and standard of living as their bank accounts and wages seem to diminish while prices get higher. The purchasing power of the currency decreases and the currency loses strength. Therefore inflation’s erosive nature necessitates the actions taken by the central bank.
Affects of Inflation on Interest Rates and Investment
If inflation is a concern then the central bank will raise interest rates to appease the inflationary pressure. Higher interest rates will cause inflation to slow because it will cost more for companies and consumers to borrow from banks to fund either investment spending or consumption (i.e. for consumers it will be harder to refinance a mortgage on a house to free up spending money). With more restrictive access to money, economic activity slows down and so do inflationary pressures.
The higher interest rate will cause the currency to appreciate in the eyes of investors, both domestic and foreign, as they will benefit from a higher yield on the country's assets. If the currency is now appreciating relative to other currencies, then Forex traders will buy into it in order to trade with the trend, sending even more money towards that economy.
It is therefore a delicate balance that central banks have to strike. They would like higher interest rates to strengthen the currency and promote foreign investment, but they must be aware that higher interest rates hurt domestic businesses and consumers that rely on borrowing money from banks.
In the following pages, we shall look at an example of interest rates and central banks, and their impact on the Forex market at work.
Market Reactions to Central Banks - FOMC Example
We will attempt to show how important interest rates are to currency movements by examining price action on the Forex market during a recent central bank tightening campaign. The following example focuses on the EUR/USD pair.
Let’s investigate the implication of the United States Federal Reserve’s interest rate decisions to the value of the US Dollar.
