Final answer:
When there is a surplus of dollars in the foreign exchange market, it indicates that foreign investors are not as interested in holding dollars.
Step-by-step explanation:
In the foreign exchange market, when there is a surplus of dollars, it means that the supply of dollars exceeds the demand for dollars at a given exchange rate. This surplus of dollars results in a decrease in the exchange rate between the dollar and other currencies.
For example, if the original equilibrium exchange rate was 10 pesos per dollar, a surplus of dollars might cause the exchange rate to decrease to 8 pesos per dollar.
When there is a surplus of dollars in the foreign exchange market, it indicates that foreign investors are not as interested in holding dollars, which can be caused by factors such as a decrease in confidence in the US economy or an increase in the attractiveness of other currencies.
