Interest Rate Differential FAQ
1What is interest rate differential?
It's the difference between two countries' interest rates. A higher differential means a larger swap credit when buying the higher-yield currency.
2What is a carry trade?
A carry trade involves borrowing in a low-interest-rate currency and investing in a high-interest-rate currency to profit from the rate differential.
3How do interest rate changes affect forex prices?
When a central bank raises rates, its currency typically strengthens as higher yields attract foreign capital. Rate cuts have the opposite effect, weakening the currency as investors seek better returns elsewhere.
