Carry Trade in Crypto: What It Is & How It Works

Carry trade in crypto is a strategy that profits from the interest rate difference between two assets or platforms. Borrowers pay a low rate to secure funds, then lend or stake those funds elsewhere at a higher rate, pocketing the spread. This concept originated in traditional forex markets but has found a natural home in decentralized finance (DeFi) and centralized crypto lending.

What Is the Carry Trade in Crypto?

The carry trade in crypto works exactly like its traditional counterpart: you borrow an asset with a low borrowing cost and simultaneously invest that asset in an opportunity that yields a higher return. The difference between the two rates is your “carry” profit. In crypto, the most common carry trades involve stablecoins, where lending rates on one protocol can be significantly higher than borrowing rates on another.

Traditional Carry Trade vs Crypto Version

In forex, traders borrow a currency with a low interest rate (e.g., the Japanese yen) and buy a currency with a high interest rate (e.g., the Australian dollar). The net profit comes from the interest differential, while the exchange rate risk may erode gains. In crypto, the same principle applies, but the assets are typically stablecoins (like USDC or DAI) or volatile tokens used in perpetual futures markets. The key difference is that crypto platforms often allow leveraged carry trades through flash loans or margin lending, amplifying both returns and risks.

How Does the Carry Trade in Crypto Work?

To execute a carry trade in crypto, a trader follows a three-step process:

1. Borrow an asset from a lending pool that charges a low interest rate. For example, on a DeFi platform where DAI’s borrowing rate is relatively low.
2. Deposit the borrowed asset into a different lending protocol or yield-farming opportunity that offers a higher return. That could be a stablecoin savings account on a centralized exchange or a liquidity pool on a decentralized exchange.
3. Monitor the spread and unwind the trade before rates converge or before volatility wipes out the margin.

Practical example without specific numbers:
Imagine you borrow a stablecoin from Platform A, where the supply of that stablecoin is abundant and demand to borrow is low, keeping the annualized borrowing cost minimal. You then move those stablecoins to Platform B, where borrowers are eager to pay high rates due to short-term needs (e.g., for liquidations or leveraged positions). The difference between what you pay Platform A and what you earn from Platform B becomes your profit – provided the exchange rate between the two platforms’ tokens does not fluctuate.

Where Spreads Come From

Interest rate differences in crypto arise from:

• Supply and demand imbalances – Some protocols have excess liquidity (low borrow rates) while others face a shortage (high lend rates).
• Perpetual futures funding rates – In perpetual markets, longs pay shorts (or vice versa) based on the difference between the perpetual price and the spot price. A trader can earn positive funding by taking the opposite side of the prevailing funding rate.
• Cross-chain arbitrage – Bridging assets between blockchains can expose rate disparities because liquidity is fragmented.

Risks of the Carry Trade in Crypto

While the carry trade in crypto can generate steady gains, it carries several dangers that beginners must understand.

• Liquidation risk – If you borrow against collateral and the collateral’s value drops, the platform may liquidate your position. Even if you borrowed a stablecoin, your collateral (e.g., ETH) can lose value, forcing a forced sale at a loss.
• Volatility risk – The borrowed asset itself may depeg or become volatile. For instance, if you borrow a stablecoin that loses its peg, you might owe more in value than you originally borrowed.
• Platform risk – A DeFi protocol can be exploited by a hack, frozen by a governance attack, or suffer from oracle failures, leading to loss of deposited funds.
• Rate convergence – The interest rate spread can shrink or reverse unexpectedly. If borrowing costs rise and lending yields drop simultaneously, the carry trade can become unprofitable.

Critical Safety Measures

Risk	Mitigation Strategy
Liquidation	Keep a high collateralization ratio (e.g., borrow only a fraction of your collateral’s value)
Volatility	Use stablecoin-to-stablecoin pairs or overcollateralize with non-volatile assets
Platform	Only use audited, widely tested protocols with insurance coverage (where available)
Rate change	Set stop-loss alerts and be ready to close the trade if the spread narrows

Tools Used for Carry Trade in Crypto

Several platforms and instruments enable the carry trade in crypto, each with its own mechanics and risk profile.

• Centralized lending platforms – Exchanges like Binance or Kraken offer margin borrowing and staking. You can borrow a stablecoin at one rate and lend it on the same exchange’s earn products if the rates differ – though spreads are often slim.
• DeFi lending protocols – Compound, Aave, and Morpho allow users to supply and borrow assets. Because these pools are dynamic, arbitrage opportunities can appear. Flash loans can also be used to execute carry trades in a single transaction.
• Perpetual futures funding rate arbitrage – Traders can go long on a perpetual contract while shorting the same asset on spot (a “basis trade”) to capture the funding rate paid by the other side. This is a form of carry trade that profits from the difference between the perpetual price and the spot price.

Example: Funding Rate Carry

If the majority of traders are long a perpetual future, the funding rate becomes positive, meaning longs pay shorts every funding interval. A trader can short the perpetual contract and simultaneously buy an equal amount of the spot asset, locking in the funding rate as profit. The position is delta-neutral, so price moves do not affect the payout – only the funding flow matters.

Conclusion

Carry trade in crypto offers an attractive way to profit from market inefficiencies without relying on directional price predictions. By borrowing low and lending high – or by capturing funding rate differentials – traders can earn a stream of passive-like income. However, the risks of liquidation, volatility, and platform failures mean that beginners should start small, use low leverage, and always monitor their positions. Understanding the mechanics of the carry trade in crypto is a valuable skill for anyone looking to move beyond simple buy-and-hold strategies.
