Interest Rate Differential FAQ

1

What 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.

2

What 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.

3

How 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.
