Correct Option
The correct option is 2 and 3 only.
Explanation
The Interest Rate Differential is a key concept in international finance and macroeconomics. It represents the difference in interest rates between two distinct economic zones or countries. This differential influences global capital flows, exchange rates, and the attractiveness of assets in international markets.
Statement-wise Analysis
- Statement 1 is Incorrect.
The Interest Rate Differential refers specifically to the difference in interest rates (nominal or real) between two countries, not inflation rates. The difference in inflation rates between two countries is known as the Inflation Differential, which is a core component of the Purchasing Power Parity (PPP) theory.
- Statement 2 is Correct.
Global investors seeking higher returns are generally attracted to countries with higher interest rates relative to others. This phenomenon drives strategies such as the "Carry Trade," where investors borrow in a low-interest currency and invest in a high-interest currency to profit from the differential.
- Statement 3 is Correct.
When a country raises its domestic interest rates, it offers higher returns on interest-bearing assets (like bonds). This attracts foreign capital inflows (Foreign Portfolio Investment). To invest in these assets, foreign investors must purchase the domestic currency, thereby increasing its demand. Consequently, this increased demand leads to an appreciation of the domestic currency against foreign currencies.
Key Takeaway
Interest Rate Differential drives capital mobility; higher domestic interest rates attract foreign capital, increasing demand for the domestic currency and causing it to appreciate.
