Which set of factors affects foreign exchange rates?

• A. Interest rates, inflation, trade policies, and public debt.
• B. Unemployment and consumer sentiment only.
• C. Currency pegs and capital controls only.
• D. Corporate earnings announcements only.

Answer: (A)

Foreign exchange rates move because investors reprice currencies based on how attractive a country’s economy is relative to others, which shows up through several linked factors. Higher interest rates tend to attract capital to a country, increasing demand for its currency and potentially boosting its value. Inflation matters because higher inflation can erode purchasing power and, if not matched by policy, can lead to a weaker currency. Trade policies influence the trade balance and current account, changing how much the country earns or pays in foreign currency and thus affecting demand for the currency. Public debt signals fiscal health and sovereign risk; a heavier debt load can raise risk premia and pressure the currency lower. When these elements shift, they set the direction of currency movements through changes in capital flows and the relative balance of demand and supply for each currency.

Unemployment and consumer sentiment are important for gauging the health of an economy, but they don’t directly drive currency values in the same comprehensive way as the four factors above. Policy tools like currency pegs and capital controls can influence exchange rates, but they are mechanisms or constraints rather than the broad set of fundamentals that typically moves rates in open markets. Corporate earnings announcements can affect investor sentiment and selective capital flows, but they aren’t the broad drivers of FX rates across currencies.
