The correct option is A, C only. Explanation & Key Takeaways: • Higher Real Interest Rate • Higher real interest rates can attract foreign investors as they can get a higher return on their investment. This increases demand for the country's currency, which can lead to an appreciation in its value. • Higher Nominal Interest Rate • Higher nominal interest rates might also attract foreign investors, but this scenario depends on relative inflation. If a country has high nominal interest rates but also high inflation, then the potential gain from higher nominal interest could be offset by the loss of purchasing power due to inflation. • Lower Inflation • Lower inflation generally indicates a stable economy wherein the purchasing power of the currency is well maintained. Inflation erodes purchasing power, and hence, lower inflation rates are often desirable and attract foreign investors, potentially leading to an appreciation of the currency. • Higher Inflation • Higher inflation can lead to a depreciation in the value of a currency because it erodes the purchasing power of money over time. This makes goods more expensive, and in turn, reduces the appeal for foreign investors, potentially leading to a depreciation of the currency. • Large Current Account Deficit • Large current account deficits usually contribute to the depreciation of a currency. This is because a deficit means that the country is importing more goods, services, and capital than it is exporting. To pay for these imports, it sells its own currency, increasing supply and reducing its value. Therefore, a large current account deficit generally leads to depreciation, not appreciation, of the currency.
