What Is the Yen Carry Trade? Here's How It Works and Its Impact

Yen carry trade is a strategy in which investors borrow Japanese yen at a low cost, then exchange it for another currency to purchase assets offering potentially higher returns. The strategy can generate profits as long as the yield differential remains attractive and the yen does not appreciate sharply.

Key Takeaways

• Investors borrow yen at low interest rates to purchase higher-yielding assets.
• Profits come from the yield differential, but they can disappear when the yen strengthens.
• The simultaneous unwinding of positions can put pressure on stocks, cryptocurrencies, and other risk assets.

What Is the Yen Carry Trade?

The yen carry trade is a form of currency carry trade. In this strategy, the yen serves as the funding currency, while the borrowed funds are allocated to currencies or assets with potentially higher returns.

Investors can use these funds to purchase bonds, stocks, emerging-market currencies, commodities, or crypto assets. The difference between the cost of borrowing yen and the investment return is the source of potential profit.

This strategy generally works better when market volatility is low. Investors also expect the yen to remain stable or weaken against the target currency.

If the yen strengthens instead, the yen-denominated debt becomes more expensive when converted back. This can erase the profit generated by the interest-rate differential.

How Does the Yen Carry Trade Work?

The yen carry trade can be explained through a simple example.

An investor borrows funds worth 10 million yen at a low interest cost. The funds are then converted into U.S. dollars and used to purchase bonds, stocks, or other assets that offer higher returns.

Potential profits come from:

• The difference between the borrowing cost and the investment return.
• An increase in the price of the purchased asset.
• A weakening of the yen against the target currency.
• The use of leverage to increase the position size.

For example, the funding cost in yen is 1%, while the purchased asset provides a 5% return. In simple terms, this creates a gross spread of 4% before accounting for transaction fees, taxes, leverage, and exchange-rate movements.

However, this profit is not guaranteed. If the yen appreciates by 6% against the target currency, the foreign-exchange loss can exceed the 4% yield differential.

The investor ultimately has to spend more money to buy yen and repay the loan.

Why Is the Yen Used as a Funding Currency?

Japan has a long history of accommodative monetary policy and low interest rates. This has made yen funding relatively inexpensive compared with funding in several other currencies.

When interest rates fall, financial institutions can obtain funds at a lower cost. These funding conditions then influence lending rates and financial-market activity.

In addition to its low cost, the yen has several characteristics that support its use as a funding currency:

• The yen foreign-exchange market is highly liquid.
• The yen is easy to trade globally.
• Japan has a large financial system.
• Investors can access funding through loans or derivatives.
• The interest-rate differential with other countries has at times been relatively wide.

As long as Japanese interest rates remain lower than those in the investment destination, the incentive to conduct carry trades remains. However, higher Japanese interest rates can narrow this differential.

Tighter monetary policy can also strengthen the yen. The combination of rising funding costs and an appreciating yen makes carry trades less attractive.

What Are the Benefits and Risks of the Yen Carry Trade?

The main benefit of the yen carry trade comes from the interest-rate differential. Investors can borrow at a low cost and allocate the funds to assets that provide higher returns.

The strategy can also generate additional gains when the yen weakens. Investors need less money to buy back yen when repaying the loan.

However, the risks are also substantial.

Exchange-rate risk

A stronger yen raises the cost of repaying the debt. A sharp exchange-rate movement can erase all carry-trade profits.

Leverage risk

Many market participants use leverage. A small adverse price movement can cause major losses, margin calls, or liquidation.

Asset-price decline risk

Assets purchased with borrowed funds can decline in value. Investors may then face both an investment loss and a higher cost of repaying the debt.

Policy-change risk

Higher Japanese interest rates can reduce the profit from the yield differential. Expectations of tighter policy can also prompt investors to close positions early.

Liquidity risk

When many investors exit at the same time, asset prices can fall more quickly. Market participants may not obtain the selling price they expected.

Why Can a Stronger Yen Shake the Market?

Investors conducting yen carry trades generally sell yen to purchase other currencies and assets. When the yen begins to strengthen, these positions can incur losses.

To limit losses, investors sell the assets they previously purchased. The proceeds are then used to buy yen and repay the loans.

This process is called carry trade unwinding. If it occurs simultaneously, the impact can create the following cycle:

1. The yen strengthens.
2. Carry-trade losses increase.
3. Investors sell risk assets.
4. Demand for yen increases.
5. The yen strengthens further.
6. Other investors also close their positions.

Large short positions in the funding currency can amplify exchange-rate reactions when the central bank tightens policy. Leveraged investor activity can also magnify market movements.

Because the scale of carry trades is difficult to calculate precisely, the market does not always know how many positions need to be closed. This uncertainty can increase volatility.

The Impact of the Yen Carry Trade on Stocks and Crypto

The yen carry trade can support stocks when cheap funding flows into global markets. Investors have additional capital to purchase technology stocks, high-yield bonds, emerging-market assets, and speculative instruments.

The effect can reverse when positions begin to unwind. Investors sell assets to reduce leverage and obtain yen.

Impact on stocks

Stock indexes can weaken when investors reduce positions simultaneously. Highly valued stocks and those sensitive to liquidity are generally more vulnerable to pressure.

Japanese stocks can also face additional pressure. A stronger yen can reduce the value of exporters’ overseas earnings when converted into the domestic currency.

Impact on crypto

Bitcoin and altcoins are among the assets sensitive to changes in liquidity and risk appetite. When carry trades unwind, investors tend to reduce exposure to volatile assets.

The crypto market operates 24 hours a day and uses substantial leverage. Initial selling can trigger futures-position liquidations and then accelerate price declines.

However, declines in stocks or crypto are not always caused by the yen carry trade. Global interest-rate policy, economic data, leverage conditions, investor sentiment, and industry-specific issues can also affect markets.

Conclusion

The yen carry trade is a strategy of borrowing yen at a low cost to purchase assets offering higher returns. The strategy can be profitable when interest-rate differentials are wide, volatility is low, and the yen remains stable or weakens.

The greatest risk emerges when the yen strengthens. Investors must buy back yen at a higher price, while the assets they purchased may decline in value.

If many positions are closed simultaneously, selling can spread to stocks, bonds, emerging-market currencies, and crypto. Leverage then amplifies the pressure through margin calls and liquidations.

For this reason, movements in the yen are relevant not only to forex traders. Stock and crypto investors also need to monitor Japanese monetary policy, global interest-rate differentials, and changes in risk sentiment.
