Carry refers to the profit from the interest rate differential between two currencies in a forex trade. It arises when a trader borrows funds in a currency with a low interest rate and invests them in a currency with a high interest rate, keeping the difference. Carry is distinct from currency appreciation—you profit whether the exchange rate moves or stays flat.
How Carry Works
A carry trade works through the interest you earn on the foreign currency position. When you hold a currency pair, your broker holds the base currency (earning interest) and finances the position in the quote currency (paying interest). The net interest difference between these two currencies is the carry. For example, if one currency yields 5% and the other yields 2%, you collect approximately 3% annually on your position.
Holding Periods and Time Horizon
Carry trades are meant to be held over days, weeks, or months—not closed intraday. The longer you hold, the more carry you accumulate. This strategy appeals to traders who want a return beyond price movement and are willing to hold positions through minor fluctuations. Unlike scalping or day trading, carry rewards patience.
Risks in Carry Trading
Carry trading is not risk-free. Sudden exchange rate movements can eliminate months or years of carry income in a single trade. Central banks can also change interest rates unexpectedly, removing the carry advantage. Some currency pairs lack sufficient liquidity, making it difficult to enter or exit large positions. Using leverage amplifies both gains and losses, turning small market moves into significant account impacts.
Managing Carry Positions
The carry available on any pair changes with interest rate cycles. During periods of rising rates in high-yield currencies, carry attracts more traders and can become crowded. This crowding sometimes precedes sharp reversals. Always measure carry against volatility risk and monitor central bank policy announcements carefully.
