This paper examines the major considerations that governments must weigh when formulating monetary and exchange rate policy. It discusses how exchange rates affect export and import prices, current account balances, inflation, and employment levels. The paper explores the trade-offs inherent in choosing between fixed and floating exchange rate regimes and the structural conditions required for each to function effectively. Using China's pegged yuan policy as a central case study, the paper illustrates how currency management can simultaneously stimulate export growth, suppress imports, and fuel domestic inflation — and why finding the equilibrium point across all these variables is essential to sustainable economic performance.
There are a number of considerations that a country must take into account when setting monetary and exchange rate policy. A country's exchange rate affects the price of its export goods on world markets and the price of import goods in the domestic market. Relative price is a key driver of demand, so the exchange rate influences demand for domestic goods internationally and for imported goods locally. Thus, the current account is a significant consideration for governments when setting monetary and exchange rate policy (Pugel, 2007).
Another major consideration involves internal economic issues such as inflation and unemployment. The current account is one of the factors that influences employment. For an economy to reach full employment, a country must maintain the correct balance of exports and imports, and finding the appropriate range for the exchange rate can help facilitate that equilibrium.
In addition, the country must consider its own inflation rate. Because monetary policy — interest rates in particular — affects the rate of inflation, policymakers frequently use it to moderate inflation in the domestic economy. Setting monetary and exchange rate policy requires balancing the need to contain inflation against the need to spur economic growth. The rate of inflation will not only affect domestic consumption but will also impact international trade. Furthermore, if the government accepts the Phillips Curve as a valid framework, the rate of inflation is also tied to the level of employment. All of these concerns must be weighed simultaneously in order to find the equilibrium point at which employment is maximized and inflation is contained.
"Structural conditions for effective regime choice"
A highly publicized example of this interplay can be found in the study of China's exchange rate policy. China fixes the rate of its yuan to the dollar on a pegged float, where the float is minimal. This policy results in Chinese exports being underpriced, making them highly attractive in world markets (Dunaway, 2010). Two direct consequences of this policy are a strong export sector and a weak import sector, as foreign goods become very expensive within China.
While China's economy has been growing rapidly, its currency policy also facilitates high rates of inflation (Batson & Back, 2010). This creates its own problems in the internal market, particularly given the country's high level of wealth disparity. In addition, rising inflation puts pressure on the central government: the peg to the dollar becomes more expensive to maintain, assuming China raises interest rates in order to address that inflation.
Monetary and exchange rate policies are used to address issues such as the current account and inflation, but they also have an impact on the level of employment in a country and the level of domestic consumption as well. Even business investment is affected, because higher interest rates lead to higher required rates of return, discouraging investment and innovation. Nations must find the right balance among these different outcomes in order to maintain employment, output, and inflation at healthy, sustainable levels. Monetary and exchange rate policy, therefore, is central to finding this equilibrium point.
