Fixed Exchange Rate - Criticisms

Criticisms

The main criticism of a fixed exchange rate is that flexible exchange rates serve to adjust the balance of trade. When a trade deficit occurs, there will be increased demand for the foreign (rather than domestic) currency which will push up the price of the foreign currency in terms of the domestic currency. That in turn makes the price of foreign goods less attractive to the domestic market and thus pushes down the trade deficit. Under fixed exchange rates, this automatic rebalancing does not occur.

Governments also have to invest many resources in getting the foreign reserves to pile up in order to defend the pegged exchange rate. Moreover a government, when having a fixed rather than dynamic exchange rate, cannot use monetary or fiscal policies with a free hand. For instance, by using reflationary tools to set the economy rolling (by decreasing taxes and injecting more money in the market), the government risks running into a trade deficit. This might occur as the purchasing power of a common household increases along with inflation, thus making imports relatively cheaper.

Additionally, the stubbornness of a government in defending a fixed exchange rate when in a trade deficit will force it to use deflationary measures (increased taxation and reduced availability of money), which can lead to unemployment. Finally, other countries with a fixed exchange rate can also retaliate in response to a certain country using the currency of theirs in defending their exchange rate.
