Carry trade

What is Carry trade in forex and CFD trading

A carry trade is a strategy involving the simultaneous borrowing of a currency with a low interest rate and investing in a currency with a high interest rate, aiming to profit from the positive interest rate differential, known as the carry. The carry trade matters for real trading decisions because the accumulated daily swap payment or credit often exceeds the price movement of the pair, making financing cost the primary P&L driver. The profit or loss from the carry component is verified on a trading platform by reviewing the positive swap value accumulated daily on the open position, a concept among many covered in our forex glossary.

Key facts about Carry trade

• Primary Profit Source: The interest rate differential (swap), rather than capital appreciation, is the main source of P&L.
• Duration: Carry trades are long-term positions, often held for several months to over a year to maximize the accumulated interest income.
• Cost Calculation: The net interest profit is calculated as: Swap Rate = (High Yield Rate – Low Yield Rate) × Position Size.
• Risk Factor: The primary risk is exchange rate volatility, where a sharp appreciation of the low-interest rate currency (funding currency) can erase months of positive swap income.
• Target Pairs: Typical carry trade pairs involve the Japanese Yen (JPY) or Swiss Franc (CHF) as the funding currency, and the Australian Dollar (AUD) or New Zealand Dollar (NZD) as the investment currency.
• Economic Driver: The trade relies fundamentally on the stability of the interest rate differential, which is directly tied to central bank monetary policy divergence.
• Execution Focus: Competitive swap rates offered by the broker are far more critical than ultra-low spreads, given the long holding period.

How Carry trade works in forex and CFD trading

The mechanics of a carry trade are straightforward: open a position that pays the trader interest daily, and hold it long enough for the accumulated interest to generate substantial profit.

The process involves these sequential steps:

1. Identify Differential: The trader locates two currencies with a significant, stable positive interest rate difference (e.g., AUD has 4.35% and JPY has 0.1%).
2. Select Direction: The trader buys the high-interest currency and simultaneously sells the low-interest currency (e.g., buying AUD/JPY).
3. Position Execution: A long-term position is opened, designed to capture the daily swap credit, ensuring the broker’s terms offer a competitive positive swap.
4. Swap Accumulation: Every 24 hours, the broker applies a positive swap credit to the position, representing the daily portion of the interest rate differential.
5. Risk Monitoring: The position must be monitored for technical breakouts against the trade and for changes in the central banks’ forward guidance, which would threaten the differential.
6. Trade Closure: The position is closed either when the exchange rate moves sufficiently against the trade to pose a risk to the total capital, or when central bank policy signals the differential is about to narrow.

Example of Carry trade with a real trade

This example shows the profit dynamics of a carry trade focusing on the swap component over a 1-year holding period.

• Instrument: AUD/JPY (AUD yield higher than JPY yield)
• Position size: 1 standard lot (100,000 AUD)
• Holding Period: 360 days
• Daily Swap Credit (Example): +¥100.00 per lot (Approx. +$0.68 USD)

P&L Calculation (Swap Component Only): Total Swap Credit (JPY): 360 days × ¥100.00/day = ¥36,000. Convert to USD (at exchange rate 1 USD ≈ 150 JPY): ¥36,000 / 150 = $240.00.

Capital Appreciation (Example): Assume the pair moves against the trade by 150 pips (Loss). Capital Loss (Pip Value): 150 pips × $6.67/pip ≈ $1,000.50.

Net P&L (in USD): Swap Credit – Capital Loss = $240.00 – $1,000.50.

Result: -$760.50 net loss. This demonstrates the risk: even with positive swap, adverse price movement can result in a loss, but the swap partially offsets it.

How Carry trade affects your cost and risk

The success of a carry trade depends entirely on the size and stability of the positive swap credit versus the exchange rate movement.

Carry trade compared with related concepts

Carry trade vs Position trading

The carry trade is a specific type of position trading where the primary motivation is the positive interest rate differential (swap), treating the price movement as a secondary, directional risk. Position trading is a broad long-term strategy where the primary motivation is capturing capital appreciation from macroeconomic trends, and swap is merely a cost factor that must be managed. A carry trade requires a large, stable rate differential.

Carry trade vs Arbitrage

A carry trade is not arbitrage, as it involves significant market risk (exchange rate volatility) and the return is not guaranteed. Arbitrage is a risk-free profit strategy that exploits temporary price discrepancies between markets or instruments, where the profit is locked in immediately with virtually no exposure to market movement. The carry trade can result in a total loss of capital.

How Afterprime handles Carry trade

Afterprime offers competitive swap rates on major currency crosses through its ECN/STP execution model, which bases swap calculations on underlying interbank rate differentials. Traders can find detailed daily swap rates listed in the instrument specifications on the MT4/MT5 platforms, allowing for accurate projection of the swap component of the carry trade.

Zero commission is particularly material for carry trades, which require opening and closing positions that may be held for months or years. At standard brokers charging $7 per lot, a 1-lot position incurs $14 in round-turn commission. For carry traders managing multiple positions or scaling in and out, these fixed costs directly reduce the net swap gain. Afterprime’s zero commission structure preserves the full swap credit.

The combination of competitive swap rates and zero commission makes Afterprime’s cost structure well-suited for carry trade strategies where every dollar of transaction cost reduces the net interest income captured over the holding period.

Broker differences in Carry trade across the industry

The key difference among brokers regarding the carry trade lies in how they price and pass on the overnight swap charges/credits to the retail trader.

How to verify Carry trade on your trading platform

Verifying a carry trade position on your platform is essential for tracking the financial component of the strategy.

1. Select the Instrument: In the MetaTrader 4 (MT4) or MetaTrader 5 (MT5) Market Watch window, right-click on the target currency pair (e.g., AUD/JPY).
2. View Specifications: Navigate to “Specification” or “Properties” from the context menu.
3. Check Swap Long: Locate the field labeled “Swap Long” (for buying the high-yield currency) or “Swap Short” (for selling the high-yield currency).
4. Confirm Positive Value: Verify that the ‘Swap Long’ value is a positive number (credit) if buying, or that the ‘Swap Short’ is positive if selling, depending on the differential.
5. Open Trade History: Once the position is open, open the “Account History” tab in the terminal.
6. Monitor Swap Column: Check the “Swap” column for the open position; it should increase daily with a positive value, confirming the trade is receiving a daily credit.
7. Sanity check: For a genuine carry trade, the daily swap entry on the open position must be a positive value, not zero or negative, indicating an interest payment is being received.
