Currency boards are an alternative mechanism for managing exchange rates from "summary" of International Financial Management, Abridged Edition by Jeff Madura
Currency boards represent an alternative mechanism for managing exchange rates. Under a currency board system, a country's central bank is required to hold reserves in the currency to which its own currency is pegged. This means that the central bank must maintain reserves equal to 100 percent or more of the local currency in circulation. By backing the local currency with reserves in a foreign currency, a currency board ensures that the exchange rate remains fixed. The primary advantage of a currency board is its ability to provide a credible commitment to a fixed exchange rate. This commitment is seen as a way to promote stability in the foreign exchange market and to instill confidence among investors. Additionally, a currency board can help to curb inflation by limiting the money supply, as the central bank is constrained by the need to hold reserves in the pegged currency. However, there are also drawbacks to a currency board system. For one, the rigidity of a fixed exchange rate can limit a country's ability to respond to external shocks or economic fluctuations. In times of crisis, a country with a currency board may be unable to devalue its currency to boost exports or stimulate economic growth. This lack of flexibility can be a significant drawback in a rapidly changing global economy. Furthermore, the requirement to hold significant reserves in a foreign currency can be costly for a country with a currency board. Maintaining these reserves ties up funds that could otherwise be used for domestic investment or other purposes. Additionally, the need to maintain a high level of reserves can make a country vulnerable to speculative attacks on its currency, as investors may see an opportunity to profit by forcing a devaluation.- While currency boards offer a way to manage exchange rates and promote stability, they also come with limitations and costs. Countries considering the adoption of a currency board system must weigh these factors carefully and consider whether the benefits of fixed exchange rates outweigh the potential drawbacks.
