Key Takeaways
  • Carry Trade Definition: Borrowing a low-interest currency to buy a high-interest currency, profiting from the interest rate differential.
  • Swap Income: You earn positive swap (rollover) when holding high-yield currencies overnight.
  • Popular Pairs: USD/JPY, AUD/JPY, NZD/JPY, USD/TRY, USD/ZAR have historically offered carry opportunities.
  • Risks: Currency depreciation can wipe out months of swap income in hours.
  • Best For: Long-term traders who can weather volatility and have proper risk management.

What is a Carry Trade?

A carry trade is a strategy where you borrow (sell) a currency with a low interest rate and use the proceeds to buy a currency with a higher interest rate. The profit comes from the interest rate differential—the difference in central bank rates between the two countries.

For example, if the Bank of Japan rate is 0.1% and the US Federal Reserve rate is 5.25%, you could sell JPY and buy USD to earn roughly 5.15% annually (minus broker fees).

How Carry Trade Works

In forex, when you hold a position overnight, you either pay or receive swap (rollover interest):

  • Positive Swap: When you buy the higher-interest currency and sell the lower-interest one.
  • Negative Swap: When you buy the lower-interest currency and sell the higher-interest one.

Example: Buying 1 lot USD/JPY with $5 daily positive swap × 365 days = ~$1,825 annual swap income. If USD/JPY also appreciates 500 pips, you earn both swap + capital gains.

Best Currency Pairs for Carry Trade

PairLong SwapShort SwapRate Differential
USD/JPY+$8-12/lot-$15-20/lot~5% (Fed vs BoJ)
USD/TRY+$80-150/lot-$200+/lot~35%+ (High risk)
USD/ZAR+$30-50/lot-$60+/lot~8-10%
AUD/JPY+$5-8/lot-$10-15/lot~4% (RBA vs BoJ)

Note: Swap rates vary by broker. Check your broker's swap calculator or see our Low Swap Brokers guide.

Risks of Carry Trading

  • Currency Depreciation: If the high-yield currency falls, losses can exceed months of swap income.
  • Risk-Off Events: During crises, investors flee to safe havens (JPY, USD, CHF), crushing carry trades.
  • Interest Rate Changes: Central bank policy shifts can reduce or reverse rate differentials.
  • Leverage Risk: Using high leverage amplifies both swap income and potential losses.

Warning: The 2008 financial crisis wiped out years of carry trade profits in weeks as JPY surged 30%+ against high-yield currencies.

Carry Trade Strategy

  1. Choose High Differential Pairs: Focus on pairs with 3%+ rate differentials.
  2. Use Low Leverage: 1:5 to 1:10 max to survive drawdowns.
  3. Follow Trend: Only enter carry trades when the high-yield currency is in an uptrend.
  4. Set Wide Stop-Losses: Carry trades need room to breathe—500+ pip stops are common.
  5. Monitor Risk Sentiment: Exit or hedge during risk-off periods (VIX spikes, crises).
Frequently Asked Questions
What is a carry trade in forex?

A strategy where you sell a low-interest currency and buy a high-interest currency to earn the interest rate differential through daily swap payments.

How much can I earn from carry trade?

Depends on rate differential and position size. A 5% differential on 1 lot = ~$500/year in swap, but currency moves can add or subtract much more.

Is carry trade profitable?

Historically yes, during stable markets. But sharp currency moves during crises can wipe out years of swap income quickly.

What is the best pair for carry trade?

USD/JPY and AUD/JPY are popular due to Japan's ultra-low rates. USD/TRY offers higher swap but extreme volatility.

Do I need a swap-free account for carry trade?

No—swap-free accounts eliminate the swap income that carry trades rely on. You need a standard account with positive swap.

What is positive swap?

When you receive money for holding a position overnight. This happens when buying the higher-interest-rate currency in a pair.

Can I do carry trade with small capital?

Yes, but swap income on small positions is minimal. With $1,000 and low leverage, you might earn $5-20/month in swap.

What happens to carry trades during a crash?

Safe-haven currencies (JPY, CHF, USD) surge while high-yield currencies crash. Carry trades face massive losses during risk-off events.

Is carry trade the same as passive income?

It can generate passive-like income from swap, but requires active risk management. It's not truly "set and forget."

Which broker has best swap rates?

Swap rates vary significantly. Exness and IC Markets are known for competitive swap rates.

What leverage should I use for carry trade?

Low leverage (1:5 to 1:10) is recommended. High leverage amplifies swap income but also increases risk of margin call during volatility.

Can I hedge a carry trade?

Yes. Some traders hedge with options or correlated pairs. This reduces profit but protects against crashes.
