The yen carry trade was nearly risk-free. Now it's unraveling.
When the Bank of Japan raised its benchmark rate to 0.75%, it did not merely adjust a number — it quietly ended an era. For decades, the near-zero cost of borrowing in yen had underwritten a vast architecture of global investment, and Indian companies had built deeply within it. Now, as the yen strengthens and the carry trade unwinds, those who borrowed cheaply in Tokyo must reckon with the true price of borrowed time.
- The Bank of Japan's rate hike to 0.75% has strengthened the yen sharply, turning what was once a nearly risk-free borrowing strategy into a source of mounting losses for global investors.
- Indian companies with large yen-denominated loans are caught in a double bind — their repayment costs have surged in rupee terms just as refinancing options are becoming more expensive and scarce.
- The forced unwinding of yen carry trades is triggering cascading asset sales across global markets, with echoes of the August 2024 volatility episode warning of how quickly disruption can spread.
- Sectors like infrastructure, real estate, and manufacturing — which leaned hardest on cheap yen financing for long-term projects — now face the most acute pressure to restructure or sell assets.
- The window for orderly adjustment remains open, but Indian borrowers and the Reserve Bank of India must act swiftly to hedge currency exposure and stress-test balance sheets before conditions deteriorate further.
The Bank of Japan's decision to raise its benchmark interest rate to 0.75% marks a turning point in global finance — and an uncomfortable one for Indian companies that borrowed heavily in yen. After years of near-zero Japanese rates, Tokyo is now committed to normalizing monetary policy, and the consequences are rippling outward across Asia.
The yen carry trade, long a cornerstone of global investing, was built on a simple premise: borrow cheaply in Japan, deploy capital in higher-yielding markets elsewhere, and pocket the difference. Indian firms were among the most aggressive participants, drawn by historically low borrowing costs. But the BoJ's rate hike has upended that logic. Borrowing in yen is now more expensive, and the currency itself has strengthened — a devastating combination for those who must repay yen loans in rupees. Indian borrowers face rising debt service costs and a currency headwind that makes refinancing harder.
The systemic risk extends beyond individual balance sheets. As carry trades unwind, investors must sell assets and buy back yen to close positions, a process that can cascade into broader market volatility. The brief yen spike in August 2024 offered a contained preview; a sustained unwinding could prove far more severe.
The most exposed Indian companies are those in infrastructure, real estate, and manufacturing — sectors that used cheap yen financing to fund long-duration projects and now face the prospect of rolling over debt at significantly worse terms. Some may be forced into rupee markets or accelerated asset sales.
Much depends on the pace of future BoJ moves. A gradual, well-communicated tightening path gives markets room to adjust. An aggressive or unexpected shift could trigger disorder. For now, the window for orderly action remains open — but Indian borrowers who delay hedging their exposure or stress-testing their finances may find it closing faster than expected.
The Bank of Japan's decision to raise its benchmark interest rate to 0.75% represents a watershed moment in global finance—one with immediate and uncomfortable consequences for Indian companies that have borrowed heavily in yen. The move, announced in December 2024, signals Tokyo's determination to normalize monetary policy after years of near-zero rates, but it has set off a chain reaction that threatens to unwind one of the world's most popular financial strategies and expose vulnerabilities in the balance sheets of borrowers across Asia.
For decades, the yen carry trade has been a staple of global investing. The mechanics are simple: borrow money cheaply in Japan, where interest rates have been negligible, then invest those proceeds in higher-yielding assets elsewhere—emerging market bonds, equities, real estate. The profit comes from the interest rate differential. As long as the yen stayed weak or stable, the trade was nearly risk-free. Thousands of investors, from hedge funds to corporations, have built positions on this foundation. Indian companies, in particular, have been aggressive borrowers in yen, drawn by the historically low cost of capital.
But the BoJ's rate increase changes the calculus entirely. A higher Japanese interest rate makes borrowing in yen more expensive. Simultaneously, the rate hike strengthens the yen itself—investors seeking better returns in Japan are willing to pay more for the currency to access those returns. A stronger yen is devastating for anyone who borrowed in yen and needs to repay in rupees or other currencies. The rupee, like most emerging market currencies, has weakened against the yen in recent weeks. This means Indian borrowers now face a double squeeze: their debt service costs have risen in rupee terms, and the currency headwind makes refinancing more difficult.
The broader threat is to market stability. As carry trades unwind—investors closing positions to lock in losses or reduce exposure—they must sell assets and buy back yen to repay loans. This forced selling can cascade across markets, triggering volatility in equities, bonds, and currencies worldwide. The 2024 market turbulence in August, when the yen spiked unexpectedly, offered a preview of what can happen. That episode was relatively contained, but a sustained unwinding could be far more severe.
For Indian companies with material yen debt, the immediate concern is refinancing risk. Those with loans maturing in the near term face the prospect of rolling over debt at significantly higher rates. Some may be forced to tap rupee markets at unfavorable terms, or to accelerate asset sales to reduce leverage. The impact will be most acute for firms in sectors like infrastructure, real estate, and manufacturing—industries that have relied on cheap yen financing to fund long-term projects.
The BoJ's move also signals a broader shift in the global monetary environment. For years, Japanese rates were the outlier—a safe harbor of cheap money in a world where central banks elsewhere were tightening. That era is ending. As the BoJ normalizes, other central banks will face pressure to recalibrate their own policies. The Reserve Bank of India, which has held rates steady, will need to monitor currency movements and capital flows carefully. A sustained yen appreciation could drain rupees from the system as foreign investors repatriate gains.
What happens next depends partly on how quickly the BoJ moves. If rate increases are gradual and communicated clearly, markets may adjust without major disruption. But if the BoJ surprises with aggressive tightening, or if geopolitical shocks amplify currency volatility, the unwinding could be disorderly. Indian borrowers should be stress-testing their balance sheets now, locking in refinancing terms where possible, and considering whether to hedge their yen exposure. The window for orderly adjustment is still open, but it is closing.

Why does a rate increase in Japan matter so much to Indian companies?
Because thousands of Indian firms borrowed in yen when rates were near zero. It was cheap money. Now that the BoJ is raising rates, those loans are becoming expensive to service, and the yen itself is getting stronger—which means it takes more rupees to repay the same amount of yen debt.
So it's a currency problem, not just an interest rate problem?
Both. The interest rate hike makes borrowing more expensive going forward. But the yen appreciation is the immediate shock. If you borrowed 100 million yen two years ago, you might have needed 60 crore rupees to repay it. Today, you might need 65 crore. That's real money, especially for companies with thin margins.
What's the yen carry trade, exactly?
It's a bet that's been working for twenty years. You borrow in yen at almost no cost, invest the money somewhere that pays better—maybe Indian bonds, maybe stocks—and pocket the difference. As long as the yen stays weak, you make money. But if the yen strengthens, you lose on the currency conversion when you have to buy yen to repay the loan.
And now everyone is trying to unwind at once?
Not quite yet, but the incentive to unwind is growing. Every day the yen gets stronger, the losses mount. Some investors will start closing positions, which means selling assets and buying yen. That selling pressure can spread to other markets—stocks, bonds, currencies. It's a contagion risk.
Which Indian companies are most exposed?
Infrastructure firms, real estate developers, manufacturers—anyone who needed long-term, cheap capital and found it in Japan. They're the ones now facing refinancing at much higher rates, or sitting on unrealized currency losses.
Is there a way to protect against this?
Hedging, if you can afford it. Locking in refinancing terms early. Selling assets to reduce leverage. But the best time to do those things was months ago. Now, the window is narrowing.
