Carry Trade Strategy: Earning Interest While You Trade
The carry trade lets traders earn daily interest by holding a higher-yielding currency funded by a lower-yielding one.
Carry Trade Strategy: Earning Interest While You Trade
The carry trade is one of the oldest and most popular forex strategies. Instead of betting purely on price direction, you earn a daily interest payment simply for holding a position. It sounds easy, but the carry trade carries specific risks every trader must understand.
How the Carry Trade Works
The carry trade involves:
- Borrowing (selling) a currency with a low interest rate — the "funding currency."
- Buying a currency with a higher interest rate — the "target currency."
- Earning the difference as daily interest, known as rollover or swap.
Example
If AUD pays 4.00% and JPY pays 0.10%, holding AUD/JPY long earns roughly 3.90% annualized, paid out daily as positive swap. You profit whether the price moves — as long as it doesn't fall enough to wipe out the interest earned.
Popular Carry Trade Pairs
| Pair | Funding | Target | Classic Use |
|---|---|---|---|
| AUD/JPY | JPY | AUD | Most popular carry trade |
| NZD/JPY | JPY | NZD | Higher yield, higher risk |
| MXN/USD | USD | MXN | Emerging-market carry |
| TRY/JPY | JPY | TRY | High yield, high risk |
Why It Works
Capital naturally seeks higher returns. When investors, funds, and institutions borrow cheaply in yen or francs to invest in higher-yielding currencies, they push the target currency higher. This creates a self-reinforcing cycle — until it breaks.
The Risks
The carry trade is not free money. Its biggest weakness is currency risk:
- Unwinding — when risk sentiment flips, traders rush to exit carry trades. The target currency collapses quickly, erasing months of interest in hours.
- Leverage amplifies losses — most carry trades use leverage, so a 5% adverse price move can wipe out a year of interest.
- Rate changes — if the funding currency raises rates or the target cuts, the differential shrinks.
- Liquidity gaps — carry trades often involve exotic currencies that gap during stress.
When Carry Trades Work Best
- Risk-on environment — stock markets rising, volatility low
- Stable differentials — central banks holding policy steady
- Trending target currency — upside price movement adds to interest income
When to Avoid Carry Trades
- Risk-off crises — wars, pandemics, financial stress
- Funding currency strengthening — indicates unwinding pressure
- High volatility regimes — VIX above 25
A Simple Carry Trade Plan
- Identify a positive-swap pair with a stable differential
- Confirm the broader trend supports the long position
- Use modest leverage — carry trades are long-term holds
- Set a stop-loss wider than usual to survive volatility
- Monitor risk sentiment daily and exit at the first sign of stress
Swap vs Profit
Your broker's swap rate is what you actually receive or pay daily. It is based on the interbank differential but adjusted by the broker. Always check the swap table before opening a carry position, as a single violent reversal can wipe out months of interest.
