Japan Carry Trade: How the Yen Carry Trade Works and Unwinds

What is the Japan carry trade?

The Japan carry trade is a strategy in which investors borrow Japanese yen at relatively low interest rates and use the funds to invest in higher-yielding currencies or assets. It becomes less attractive when Japanese rates rise, the yen strengthens, or market volatility increases.

Key Takeaways

1. The Japan carry trade typically involves borrowing low-cost yen and investing in assets offering higher potential returns.
2. Its profitability depends on more than interest rates. Changes in the yen exchange rate can significantly increase or reduce the return.
3. A yen carry trade unwind occurs when investors sell the assets they bought and purchase yen to repay their funding.
4. The exact size of the Japan carry trade cannot be measured because yen-funded positions exist across currencies, bonds, derivatives and other markets.
5. In 2026, higher Japanese interest rates, yen volatility and expectations for further Bank of Japan tightening have made the risk of carry-trade unwinding more relevant to global markets.

What Is the Japan Carry Trade?

A carry trade attempts to profit from differences in interest rates between two currencies or markets.

Japan became particularly important to this strategy because Japanese interest rates remained extremely low for decades. That made the yen attractive as a funding currency.

In simplified terms, an investor could:

1. Borrow Japanese yen at a low interest rate.
2. Exchange the yen for another currency.
3. Invest in an asset offering a higher yield.
4. Later sell the asset, convert the proceeds back into yen and repay the original borrowing.

For example, suppose yen funding costs 1% annually while an investment denominated in another currency generates 4%. Before transaction costs and currency movements, the interest-rate difference would be approximately 3%.

This difference is known as the carry.

However, that 3% does not represent a guaranteed profit. Currency movements can be considerably larger than the interest-rate differential.

That is why the basic pricing logic of a carry trade can be expressed as:

Carry trade return ≈ investment yield − funding cost ± currency movement − trading and hedging costs

The exchange-rate component is particularly important when analysing the Japanese yen carry trade.

Why Has Japan Been So Important to Carry Trades?

Japan spent much of the period following the 1990s with very low interest rates as policymakers attempted to combat weak growth and low inflation.

Later, the Bank of Japan introduced increasingly accommodative monetary policies, including quantitative easing and eventually negative short-term interest rates.

For global investors, this created a relatively inexpensive source of funding.

The modern yen carry trade expanded significantly after 2013 and became especially attractive during 2022 and 2023. During that period, central banks including the US Federal Reserve raised interest rates rapidly while Japanese rates remained exceptionally low.

A large interest-rate difference made borrowing yen and holding higher-yielding currencies more attractive.

A weakening yen could further improve the economics of the trade because investors would ultimately need fewer units of the foreign currency to buy back the yen required to repay their borrowing.

How Does the Yen Carry Trade Make Money?

There are two major potential sources of return.

The first is the interest-rate differential.

If an investor funds a position at a low Japanese interest rate and invests in an asset with a higher yield, the difference may produce positive carry.

The second is the exchange rate.

Suppose an investor borrows yen and converts the money into US dollars. If the yen weakens against the dollar during the life of the position, converting the dollar investment back into yen may produce an additional currency gain.

The opposite is also true.

If the yen strengthens sharply, the investor needs more dollars to buy the yen required to repay the original borrowing. That currency loss can exceed the income generated from the interest-rate differential.

This explains one of the central features of carry trades: relatively small recurring returns can sometimes be exposed to much larger currency losses.

When Does a Japan Carry Trade Tend to Work — and When Does It Not?

The yen carry trade tends to be more attractive when Japanese funding costs are low, interest rates elsewhere are significantly higher, the yen is stable or weakening, and financial-market volatility is relatively subdued.

These conditions allow investors to collect the interest-rate differential without large adverse moves in the funding currency.

The environment becomes less favourable when Japanese rates rise, foreign interest rates fall, or the yen appreciates.

Volatility also matters.

Even if an interest-rate differential remains positive, a sudden move in the exchange rate can make the trade unattractive. Investors using leverage may have to close positions before they have time to benefit from the long-term interest-rate difference.

This means a carry trade is generally a poor fit for market conditions characterised by rapidly changing monetary policy, strong appreciation in the funding currency or unusually high volatility.

What Are the Main Risks of the Yen Carry Trade?

Currency risk is the most obvious danger.

An investor might expect to earn several percentage points from the interest-rate differential, but a rapid 5% or 10% appreciation in the yen could easily overwhelm that expected carry.

Interest-rate risk is another factor. If the Bank of Japan raises rates, borrowing yen becomes more expensive. If another central bank cuts rates simultaneously, the difference between the two interest rates becomes even smaller.

Leverage can amplify both effects. Many institutional strategies use borrowed capital or derivatives, so relatively modest movements can force positions to be reduced quickly.

Finally, carry trades can become crowded. If many investors hold similar positions and market conditions suddenly change, they may all try to exit at approximately the same time.

That is when a normal adjustment can develop into a carry trade unwind.

What Is a Japan Carry Trade Unwind?

A Japan carry trade unwind happens when investors close positions financed with Japanese yen.

The process is essentially the reverse of opening the trade.

An investor sells the foreign currency or asset that was purchased with borrowed yen, converts the proceeds back into yen and repays the funding.

The important part is that closing the trade creates demand for yen.

If many investors unwind positions simultaneously, this can produce a feedback loop:

foreign assets are sold → yen is bought → the yen strengthens → remaining carry positions become less profitable → more investors close positions.

This is why the phrase "Japan carry trade unwind" often appears during periods of sudden yen appreciation and broader financial-market volatility.

What Happens When the Yen Carry Trade Unwinds?

The first direct effect is usually increased demand for the Japanese yen.

That can cause the yen to appreciate against currencies that were previously bought using yen funding.

But the impact can extend much further.

If investors used borrowed yen to purchase equities, bonds or higher-yielding currencies, unwinding the trade requires some of those positions to be sold. As a result, a rapid unwind can contribute to declines across multiple markets.

The extent of the effect depends on where the borrowed capital was invested.

Not every decline in global equities is caused by the yen carry trade, and not every rise in the yen proves that a major unwind is taking place. Carry positioning is only one part of a much larger global financial system.

The key concern is forced deleveraging: a strengthening yen can increase losses, which causes investors to reduce positions, which may further strengthen the yen and increase volatility elsewhere.

Carry Trade vs Carry Trade Unwind vs Reverse Carry Trade

The terms are related, but they should not automatically be treated as synonyms.

The phrase "Japan reverse carry trade" is sometimes used loosely to describe the unwinding of yen-funded trades.

Technically, however, an unwind simply closes an existing position. A reverse trade can mean actively establishing a new position in the opposite direction.

That distinction becomes particularly important when interpreting market commentary.

How Big Is Japan's Carry Trade?

There is no reliable figure showing the exact size of the Japan carry trade.

This is one of the most important objections to claims that a particular amount of money is about to "unwind."

Carry positions are created through multiple channels, including currency markets, bank lending, bonds and derivatives. Investors can also use leverage, making their effective market exposure larger than the amount originally borrowed.

One useful proxy is cross-border borrowing in yen. Reuters reported in September 2026 that cross-border yen borrowing had reached a record ¥360 trillion as of March, based on an analysis of Bank for International Settlements data. However, this should not be interpreted as ¥360 trillion of pure carry-trade positions.

Another indicator is speculative positioning in yen futures.

Neither measure captures the entire market.

For this reason, claims that the yen carry trade has a precise global size should generally be treated cautiously.

Is the Japan Carry Trade Unwinding in 2026?

There are signs that some yen-funded carry positions have come under pressure in 2026, but that is different from saying that the entire Japan carry trade is experiencing a disorderly unwind.

The Bank of Japan has continued moving away from the exceptionally loose monetary conditions that originally made yen funding so attractive. Its policy rate stood at 1% ahead of the September 2026 meeting, while markets were increasingly focused on the possibility of further tightening.

At the same time, the yen strengthened sharply in early September, reaching its strongest levels in several months. Reuters reported that the move was already putting pressure on some carry positions.

That does not automatically mean the yen carry trade is ending.

The economics still depend on the interest-rate differential between Japan and other markets, the direction of the yen, volatility and the assets being funded.

A gradual reduction in carry positions would also look very different from the rapid forced unwinding seen during periods of market stress.

Will the Yen Carry Trade Unwind in 2026?

No one can know with certainty whether 2026 will produce a broad yen carry trade unwind.

There are three main scenarios.

If interest-rate differences remain large and the yen stabilises, carry strategies can remain economically attractive despite higher Japanese rates.

If Japanese rates continue rising while foreign rates fall, the potential carry shrinks. Investors may then reduce positions gradually.

A more disruptive scenario would involve rapidly rising Japanese rate expectations, strong yen appreciation and increasing market volatility at the same time. That combination could force leveraged investors to close positions more quickly.

For traders, the important question is therefore not simply whether the Bank of Japan raises rates.

The more useful question is whether the combination of funding costs, interest-rate differentials, currency movement and volatility still compensates investors for the risk.

How Does the Japan Carry Trade Affect USD/JPY?

USD/JPY is closely connected to the economics of the yen carry trade, although carry positioning is only one factor affecting the currency pair.

When investors borrow or sell yen to purchase US dollar-denominated assets, those flows can contribute to yen weakness.

When the trade is unwound, the process works in the opposite direction. Investors may sell dollar assets or dollars and buy yen to repay funding, potentially strengthening the Japanese currency.

However, USD/JPY also responds to Federal Reserve policy, Bank of Japan decisions, inflation, economic growth, bond yields, currency intervention and general market sentiment.

A move in USD/JPY should therefore not automatically be interpreted as evidence of a carry trade or carry trade unwind.

What Should Traders Watch for Signs of a Carry Trade Unwind?

There is no single indicator that confirms a yen carry trade unwind.

Instead, traders can assess several factors together.

Rapid yen appreciation is an obvious signal, particularly if it occurs alongside expectations for tighter Bank of Japan policy. The difference between Japanese and foreign bond yields is also important because narrowing rate differentials reduce the economic incentive behind the trade.

Positioning data can provide another clue. Large speculative short-yen positions may indicate greater vulnerability if the currency suddenly strengthens.

Volatility should also be considered. Carry strategies tend to function better in stable markets, while sudden volatility can encourage deleveraging even when interest-rate differentials remain positive.

The strongest evidence of an unwind therefore comes from a combination of yen strength, changing rate expectations, reduced speculative positioning and broader risk reduction rather than any one indicator in isolation.

Common Misconceptions About the Japan Carry Trade

One common misconception is that all yen borrowing is part of the carry trade. Companies and financial institutions borrow yen for many reasons that have nothing to do with speculative investment strategies.

Another is that a Bank of Japan rate increase automatically destroys the carry trade. What matters is the relative difference between Japanese rates and the returns available elsewhere.

It is also incorrect to assume that every period of yen appreciation represents a major carry unwind. Currency intervention, economic data, changes in US rates and ordinary portfolio flows can all strengthen the yen.

Finally, the carry trade should not be viewed as a guaranteed method of collecting interest. Its apparent return comes with currency, leverage, liquidity and policy risks that can become significant very quickly.

FAQ

What is the Japan carry trade?

The Japan carry trade is a strategy in which investors borrow Japanese yen at relatively low interest rates and use the funds to buy higher-yielding currencies or assets. Potential returns come mainly from the interest-rate difference and, in some cases, favourable currency movements.

What is the Japanese yen carry trade?

The Japanese yen carry trade is another name for the Japan carry trade. The yen acts as the funding currency because Japan historically maintained much lower interest rates than many other major economies.

Why is the Japanese yen used for carry trades?

The yen became a major funding currency because Japanese interest rates remained exceptionally low for many years. This allowed investors to borrow yen relatively cheaply and deploy the capital into markets offering higher yields.

What happens when the yen carry trade unwinds?

Investors typically sell the currencies or assets purchased with yen funding and buy yen to repay their borrowing. If many investors do this simultaneously, yen appreciation and asset selling can reinforce each other and increase market volatility.

How big is Japan's carry trade?

The exact size is unknown. Carry trades exist across currencies, bonds, derivatives and other markets, and leverage makes total exposure difficult to calculate. Measures such as cross-border yen borrowing and speculative futures positioning can provide useful proxies but not a precise total.

What is the Japan reverse carry trade?

A reverse carry trade broadly refers to positioning opposite to the traditional yen-funded carry trade, potentially benefiting from yen strength. The term is sometimes used interchangeably with a carry trade unwind, although technically closing an existing trade and opening a new opposite position are different actions.

Is the Japan carry trade unwinding in 2026?

Some yen-funded positions have faced pressure as Japanese interest rates have risen and the yen has strengthened. However, this does not establish that the entire global yen carry trade is undergoing a large-scale or disorderly unwind.

Will the yen carry trade unwind in 2026?

It is impossible to know with certainty. The likelihood of further unwinding depends mainly on Bank of Japan policy, interest-rate differences between Japan and other economies, the direction of the yen and global market volatility.
