Exchange rate policy refers to actions taken by a government or central bank to influence the value of a country’s currency compared to foreign currencies.
Main exchange rate systems:
- Fixed exchange rate: The government or central bank keeps the currency value at a specific, set level.
- Floating (flexible) exchange rate: The currency value is determined entirely by market supply and demand.
- Managed (dirty) float: The central bank occasionally intervenes to prevent extreme or sudden changes in value.
How governments influence exchange rates:
- Direct intervention: Buying or selling foreign currency in the market. To prevent the currency from becoming too strong, the bank buys foreign reserves. To keep it from becoming too weak, the bank sells foreign reserves.
- Interest rate policy: Changing interest rates affects money flow. Higher interest rates usually attract foreign investment, which increases demand for the domestic currency.
- Foreign exchange controls: Legal rules that restrict how people or businesses buy and sell foreign currency.
Policy objectives:
- Keeping exports competitive by avoiding an overvalued currency.
- Controlling inflation caused by expensive imports.
- Creating stability for businesses to plan and invest.
- Helping balance the country’s international payments.
Limitations and risks:
- It may limit independence in setting monetary policy.
- Constant intervention can lead to the loss of foreign reserves.
- Investors may launch speculative attacks that are difficult to stop.
- A poorly set rate can cause long-term economic imbalances.
