Floating Exchange Rate System
Since 1973, floating exchange rates have become the mainstay of the international monetary system. In a floating exchange rate system, or “floats”, exchange rates are determined by supply and demand factors in the foreign exchange market. The value of the currency is set by the market, and central banks and governments do not intervene.
A floating exchange rate system has some advantages over other systems. For example, it gives countries the flexibility to adjust their trade and economic policies as needed. In addition, it allows for a more efficient allocation of resources, since currency values will be determined by market forces.
At the same time, there are some potential drawbacks to a floating exchange rate system. Many countries have experienced sharp appreciation or depreciation of their currency, causing economic instability and sharp changes in economic activity. For example, when the U.S. dollar suddenly weakened in the fall of 2008, a number of countries experienced sharp declines in their exports, resulting in an economic recession.
Floating exchange rates also require more frequent adjustments, as exchange rates can change quickly in response to changing market conditions. This requires central banks and governments to closely track exchange rates and intervene when necessary.
In addition, some exchange rate movements can cause currencies to become significantly overvalued or undervalued. This can complicate the process of setting monetary policy, as it can lead to inflation or deflation.
In order to maximize the benefits of a floating exchange rate system and reduce the potential drawbacks, countries have implemented some measures. For example, some countries have implemented capital controls, which limit the ability of citizens to invest in foreign assets and currencies.
In addition, many countries have established a primary “anchor” currency. This is a currency that is seen as a stable or safe investment, and is used as a benchmark for other currencies. By establishing an anchor currency, countries can reduce the amount of volatility in the foreign exchange market, which can make it easier to implement monetary policies.
Finally, countries have also resorted to currency intervention, in order to defend their currencies from unexpected movements. Intervention can involve either buying or selling currencies in the open market, in order to influence exchange rates.
Overall, a floating exchange rate system can provide some advantages, but it also presents some risks. As such, countries must take measures to reduce the potential risks, while maximizing the benefits.
