Carry Trades and Swap Strategies

Currencies don’t just move because of news.
They move because of capital flows, and one of the biggest drivers is the interest rate differential between countries.

What Is an Interest Rate Differential?

Every currency pair has two interest rates, one for each country.
When one central bank raises rates while the other holds steady or cuts, capital naturally flows toward the higher-yielding currency.
Traders use this concept to execute carry trades, borrowing in low-interest currencies and investing in higher-yield ones.

How Carry Trades Work

Let’s take USD/JPY as an example:

• If the Federal Reserve is hiking rates, and
• The Bank of Japan keeps rates near zero,

Traders might buy USD/JPY to earn the interest difference, or swap yield.

This is called a carry trade, and it works best when markets are calm and risk appetite is stable.

When Carry Trades Unwind

But carry trades come with risk.
When markets panic, investors unwind carry trades fast, buying back low-yielding currencies like JPY or CHF for safety.
That’s why USD/JPY often falls during risk-off periods, even if U.S. rates are higher.

Conclusion

So trading interest rate differentials is about timing the cycle.
You earn carry when rates diverge, but you need to watch for volatility that can reverse the trade.
