Carry Trade: How to Profit from Interest Rate Differences Between Currencies

Popular Carry Trade Currency Pairs

AUD/JPY: The most popular carry trade pair for retail traders. Australia has typically offered higher interest rates than Japan. AUD/JPY has high liquidity and tight spreads. NZD/JPY: Similar to AUD/JPY with slightly lower liquidity. New Zealand often has rates close to Australia. USD/MXN: Mexico offers significantly higher rates than the US (often 5-10% higher). Higher volatility and wider spreads but larger potential rollover returns. USD/TRY: The Turkish lira has had extremely high interest rates (often above 20%), making this the highest-yielding carry pair. However, persistent lira depreciation has often overwhelmed interest earnings. MXN/JPY: Direct exposure to the Mexican peso vs Japanese yen without USD intermediation. ZAR/JPY: The South African rand offers high yields but with significant political and economic risk. Each pair has a different risk profile based on the stability of the high-yielding country's economy, inflation rate, and central bank credibility.

When the Carry Trade Fails: The Unwinding

The carry trade's greatest risk is not interest rate changes but sudden exchange rate movements during risk-off events. When investors panic — during a financial crisis, geopolitical shock, or unexpected central bank action — they rush to unwind carry trades. This means selling high-yielding currencies and buying back funding currencies. The resulting moves can be dramatic: the funding currency (typically JPY or CHF) surges while target currencies (AUD, NZD, emerging market currencies) crash. The 2008 financial crisis caused massive yen carry trade unwinding, with AUD/JPY falling from 107 to 55 (a 48% decline). The 2015 Swiss franc shock saw EUR/CHF drop 30% in a single day when the Swiss National Bank removed its currency peg. The 2020 COVID crash caused AUD/JPY to fall 15% in weeks. The paradox of the carry trade is that it works best when everyone is doing it, but when everyone tries to exit at once, the trade breaks catastrophically. Margin calls force leveraged traders to unwind positions, which accelerates the move against them. Implement risk management for carry trades →

Real Example: USD/MXN Carry Trade

Scenario: In 2023-2024, the US Federal Reserve had rates at 5.5% while the Bank of Japan had rates at 0.1%. However, let's use a more dramatic example: the Mexican peso offered 11% while the Japanese yen offered 0.1%. A trader borrowing yen to buy Mexican pesos earns approximately 10.9% in annualized rollover. With a position size of $100,000 notional, daily rollover income is approximately $29.86 (10.9% / 365 days x $100,000). Over one year, rollover income = $10,900. If the exchange rate stays flat, total return = $10,900 (10.9%). If MXN/JPY appreciates 5%, total return = $15,900 (15.9%). If MXN/JPY depreciates 5%, total return = $5,900 (5.9%) — still positive because the 10.9% carry offsets the 5% exchange rate loss. But if MXN/JPY depreciates 15% (which can happen in a risk-off event), the trade loses $4,100 (-4.1%). This example does not account for leverage, which would amplify both gains and losses. With 5:1 leverage, the same trade would generate 54.5% return (positive scenario before depreciation) or a 20.5% loss (if MXN/JPY falls 15%). Build a risk management plan for carry trading →

Is carry trading safe?

No trading strategy is safe. The primary risk is that exchange rate movements can overwhelm interest earnings. A currency paying 11% interest can easily drop 15% during a risk-off event. Central banks can change rates at any time. Rate cuts reduce the carry advantage. Rate hikes can cause currency volatility. The carry trade involves leverage, which magnifies losses. Manage risk through position sizing, diversification across multiple carry pairs, and moderate leverage (2:1 to 5:1).

How much can I earn from carry trades?

Earnings depend on the interest rate differential, position size, and leverage. A $10,000 position in USD/MXN with a 5% differential earns approximately $500 annually in rollover interest ($1.37 per day). Using 5:1 leverage ($50,000 notional), annual rollover income becomes $2,500. Professional hedge funds typically generate 8-12% annually from well-diversified carry trade portfolios. The key is consistency — small daily gains compound over time.

What is the best carry trade pair?

AUD/JPY is the most popular choice for retail traders due to liquidity, tight spreads, and relatively stable interest rate differentials. For higher yields, USD/MXN provides a larger differential with higher volatility. USD/TRY offers the highest yield but the Turkish lira's persistent depreciation often overwhelms interest earnings. For most traders, AUD/JPY or NZD/JPY are the best starting points.

Do I need leverage for carry trading?

Leverage is not required but is commonly used because raw interest differentials on small positions produce modest absolute returns. A $1,000 position at 5% earns only $50 per year. With 10:1 leverage ($10,000 notional), the same trade earns $500. However, leverage magnifies exchange rate losses. Most experienced traders use moderate leverage (2:1 to 5:1) and focus on position sizing that survives temporary drawdowns.
