The carry trade is a strategy that profits from interest rate differentials between currencies. You borrow (sell) a low-interest currency and invest (buy) a high-interest currency, earning the rate difference daily. It's been one of the most popular forex strategies among institutional traders.
How the Carry Trade Works
Every currency has an interest rate set by its central bank. When you hold a forex position overnight, you earn or pay interest based on these rates.
The Strategy:
- Sell (borrow) a currency with low interest rate
- Buy (invest in) a currency with high interest rate
- Earn the interest difference daily as swap
- Hope the exchange rate stays stable or moves in your favor
Simple Example (hypothetical rates):
- Japanese Yen rate: 0.1%
- Australian Dollar rate: 4.0%
- Difference: 3.9%
- Buy AUD/JPY to earn approximately 3.9% annually

You receive this interest daily through positive swap payments.
Classic Carry Trade Pairs
Historically popular carry pairs include:
| Pair | High Rate | Low Rate | Strategy |
|---|---|---|---|
| AUD/JPY | AUD | JPY | Buy |
| NZD/JPY | NZD | JPY | Buy |
| AUD/CHF | AUD | CHF | Buy |
| NZD/CHF | NZD | CHF | Buy |
| USD/JPY | USD | JPY | Buy (when US rates high) |
Note: Interest rates change frequently. Always check current rates.
Calculating Carry Trade Returns
Swap Income
Brokers calculate swap based on the interest rate differential:
Approximate Annual Return:
Carry Return = Interest Rate Differential × Position SizeExample (hypothetical rates):
- AUD rate: 4.0%
- JPY rate: 0.1%
- Differential: 3.9%
- Position: $100,000 (1 standard lot)
- Annual carry: $100,000 × 3.9% = $3,900
- Daily carry: $3,900 ÷ 365 = $10.68 per day
In reality, broker swap rates vary and include their markup.
With Leverage
Leverage amplifies carry returns:
Example with 10:1 Leverage:
- Your capital: $10,000
- Control: $100,000
- Carry on $100,000: $3,900/year
- On $10,000 of margin that looks like 39% a year, but a 10% move against the pair wipes out the whole $10,000
Illustrative figures only, not a forecast. Leverage multiplies the currency loss in exactly the same way as the interest, so it is never a reason to take a carry trade.
Carry Trade Risks
Exchange Rate Risk
The biggest danger: currency depreciation.
Example:
- You buy AUD/JPY at 85.00
- Earn about $3,900 in carry over a year
- But AUD/JPY falls to 75.00 (1,000 pips)
- Loss on position: ¥1,000,000, about $6,700 at USD/JPY 150
- Net result: Significant loss despite positive carry
A 10% currency move erases years of carry income.
Risk-Off Events
Carry trades unwind rapidly during market panic:
- 2008 Financial Crisis: AUD/JPY fell 50% in months
- COVID-19 Crash: Dramatic carry trade unwinding
- Any risk-off event sends money to safe havens (JPY, CHF)
When markets panic, everyone exits carry trades simultaneously.
Interest Rate Changes
Central banks adjust rates:
- If the high-rate currency's rate drops
- Or the low-rate currency's rate rises
- Carry becomes less attractive
- Traders exit, causing currency moves
Leverage Risk
High leverage amplifies losses:
- 10:1 leverage = 10% currency move wipes you out
- Carry profits can't offset rapid depreciation
- Margin calls force position closure at worst times
When Carry Trades Work Best
Favorable Conditions
- Stable markets: Low volatility, no crisis
- Wide rate differentials: Significant interest difference
- Uptrending carry pair: Exchange rate moving in your favor
- Risk-on sentiment: Investors comfortable with risk
Unfavorable Conditions
- Market turbulence: Financial crises, pandemics
- Narrowing differentials: Rates converging
- Strong safe-haven demand: JPY or CHF strengthening
- Risk-off sentiment: Fear driving markets
Carry Trade Entry Strategies
Basic Approach
Simply buy high-yield against low-yield and hold.
Technical Confirmation
Enter carry trades only when:
- Technical trend supports direction
- Price is above key moving averages
- Support levels are clear for stop placement
Scale In
Build position gradually:
- Start with partial position
- Add more as trade proves correct
- Reduce exposure if conditions change
Managing Carry Trade Risk
Use Stop Losses: Don't rely on carry to offset unlimited losses.
Reasonable Leverage: Keep effective leverage modest (5:1 or less).
Monitor Sentiment: Exit or reduce before risk-off events if possible.
Diversify: Don't put all capital in one carry pair.
Take Partial Profits: Lock in gains when exchange rate moves favorably.
Watch Central Banks: Rate decisions can change everything.
