Which term best describes the relationship between inflation and currency value in a stable exchange rate scenario?

The relationship between inflation and currency value can be effectively described by the notion that inflation reduces purchasing power consistently. When inflation rises, the purchasing power of a currency diminishes, meaning that each unit of currency buys fewer goods and services over time. In the context of stable exchange rates, this diminished purchasing power can lead to a decrease in the attractiveness of that currency both domestically and internationally. As investors and individuals perceive that the currency will buy less in the future due to inflation, their demand for it may decrease, potentially weakening its overall value in the long run.

The other options do not adequately capture the dynamics at play. For example, one might think that inflation has no effect on currency strength, but this is not accurate because inflation directly impacts the perceived value of currency. Similarly, the assertion that foreign currency will always decline in value is misleading, as currency value is relative and can fluctuate based on a variety of factors, including the inflation rates of both countries involved. Lastly, stating that inflation increases demand for local currency is incorrect, as higher inflation tends to drive demand down due to reduced purchasing power and confidence in the currency. Through this lens, option A accurately encapsulates the relationship between inflation and currency value.
