Japan’s yen remains under severe pressure despite record currency intervention and higher interest rates, underscoring the widening gap between Tokyo’s policy response and the structural forces driving the currency lower.
The Ministry of Finance spent 11.7 trillion yen between April 28 and May 27 buying yen in the foreign exchange market, marking Japan’s largest-ever monthly intervention. The action briefly slowed the decline, but it did not reverse it. Within six weeks, the yen weakened to 162.62 against the U.S. dollar, its lowest level since December 1986. The currency has continued to trade above the 162 mark, keeping traders focused on whether the next major threshold will be 165.
The weakness has persisted even after the Bank of Japan raised its policy rate to 1% in June, the highest level in 31 years. That move followed the central bank’s decision in March 2024 to end negative interest rates, a major shift after years of ultra-loose monetary policy. But the rate increases have not been enough to overcome the pull of higher U.S. yields, Japan’s heavy debt burden and the continued use of fiscal stimulus.
Including the 9.8 trillion yen spent on intervention in 2024, Tokyo has now deployed more than 21 trillion yen from its reserves in an effort to slow the yen’s fall. The scale of that spending has raised questions across markets about how much longer Japan can defend the currency without deeper changes to fiscal and monetary policy.
Goldman Sachs on July 6 raised its 12-month dollar-yen forecast to 165 from 155, reflecting growing expectations that the yen’s weakness has further to run. Market pricing also suggests a 72% probability that the exchange rate reaches 165 before June 2027.
The main reason remains the interest-rate gap. The U.S. benchmark rate stands at 3.50% to 3.75%, compared with Japan’s 1% policy rate. That 275-basis-point gap continues to encourage traders to borrow in yen and buy higher-yielding dollar assets. Data from the Commodity Futures Trading Commission showed speculative net short positions against the yen deepening to more than 155,000 contracts in the latest reporting week, a sign that traders are still betting on further weakness.
Why the yen remains under pressure
The yen’s slide is being driven by more than short-term trading. It reflects a deep difference between Japan’s financial structure and that of the United States.
The carry trade remains one of the clearest forces behind the move. Traders can borrow yen at extremely low real rates and move funds into U.S. assets yielding more than 4.5%. That can produce a return above 3% before any currency movement is counted. When the yen weakens further, those returns increase. This creates a powerful feedback loop: the more the yen falls, the more attractive the trade becomes, encouraging further selling of the currency.
This dynamic is difficult for Tokyo to stop with intervention alone. Currency intervention can change the pace of market moves, especially if launched during periods of thin liquidity, but it rarely changes the underlying direction unless it is backed by a meaningful shift in interest rates or fiscal policy. In Japan’s case, aggressive rate increases are difficult because of the country’s debt burden.
Japan’s government debt exceeds 250% of gross domestic product, one of the highest levels in the developed world. That leaves policymakers with limited room to raise rates without causing a sharp rise in public debt-servicing costs.
The 2026 national budget totals 122.3 trillion yen. Of that, 31.3 trillion yen is set aside for debt service, roughly one quarter of government revenue. Put simply, for every four yen collected in tax, about one yen goes to creditors. As bond yields rise, that cost is increasing quickly.
Ten-year Japanese government bond yields have climbed from 0.25% in 2022 to 2.88%. Because Japan must refinance large amounts of debt, higher yields feed into the budget over time. Most redemptions are covered through new issuance, which means the government is constantly exposed to current market rates. The interest portion of debt service is now growing faster than principal repayment.
A further rise of 100 basis points in borrowing costs could push annual debt-service costs above 35 trillion yen. That would place additional strain on public finances and could force the government to either issue more debt, raise taxes, cut spending or accept a larger deficit.
Fiscal limits restrict rate hikes
This fiscal reality limits the Bank of Japan’s ability to raise rates quickly. Every percentage-point increase in borrowing costs can add several trillion yen to the government’s interest bill. That creates a policy trap: higher rates may support the currency, but they also increase pressure on the national budget.
For that reason, traders tend to view Japan’s monetary tightening as limited and possibly temporary. Even after the Bank of Japan raised rates to 1%, many market participants remained skeptical that the central bank could continue tightening for long. The concern is not only economic growth, but also the sustainability of government finances.
At the same time, fiscal policy remains expansionary. Defense spending has risen above 9 trillion yen, equal to about 2% of GDP. Planned tax suspensions could reduce revenues by as much as 5 trillion yen. Subsidies and household support programs continue to add spending into the economy.
That puts fiscal and monetary policy at odds. The Bank of Japan is trying to tighten financial conditions, while government spending and bond issuance add liquidity and demand. Ongoing government bond purchases also complicate the message, as they can offset the impact of higher rates by keeping money flowing through the system.
To traders, this mixed approach looks less like a clear defense of the currency and more like policy inertia. Japan is taking action, but not enough to change the deeper incentives pushing money out of yen and into dollars.
Business failures show the economic cost
The weak yen is already feeding through to the domestic economy, especially among smaller companies that rely on imported goods, materials and energy.
In the first half of 2026, 5,346 Japanese firms with debts over 10 million yen went bankrupt. That was a 7.1% increase from a year earlier and marked the fifth consecutive annual rise. Of those failures, 45 were directly linked to currency volatility, the highest number ever recorded.
Wholesale companies accounted for nearly half of the bankruptcies tied to yen weakness. These firms are often caught between rising import costs and limited ability to pass higher prices on to customers. While large exporters can benefit from a weaker yen because overseas earnings are worth more when converted back into Japanese currency, smaller domestic companies face the opposite effect.
The pressure is not limited to exchange rates. Bankruptcies linked to labor shortages rose 37.7%, while failures linked to price pressures increased 27.6%. Together, the figures show how currency weakness, rising costs and demographic strain are combining to weaken parts of Japan’s business sector.
The labor market adds to the stress. Large corporations are able to offer higher wages and better benefits to attract younger workers. Smaller firms, especially outside major urban centers, are struggling to fill vacancies even when demand for their services remains steady. The latest survey period showed a record level of “labor-shortage bankruptcies,” highlighting how Japan’s aging population is becoming a direct financial risk for businesses.
A weaker yen can help some parts of the economy, particularly exporters and tourism-related companies. But the benefits are uneven. Households face higher prices for imported food, fuel and consumer goods. Smaller businesses face thinner margins. For policymakers, the currency’s decline is becoming not only a market issue but also a social and political concern.
Tokyo’s policy choices are narrowing
Japan’s options are increasingly difficult. Holding rates steady could allow the yen to weaken further, raising import costs and increasing bankruptcy risks. Raising rates more quickly could support the yen, but it would also lift debt-service costs and risk destabilizing the government bond market.
A combined approach of faster rate increases and balance-sheet reduction would send a stronger signal to currency traders. But it could also trigger sharp moves in Japanese bond yields, put pressure on banks and create wider market volatility. Given the size of Japan’s public debt and the importance of the government bond market to the financial system, policymakers are likely to move cautiously.
That caution is one reason currency intervention remains a preferred tool. Finance Minister Satsuki Katayama has repeatedly said officials will respond appropriately to excessive currency moves. Market sources suggest authorities may now favor surprise intervention, aiming to strike when liquidity is thin and the impact is greater.
Such action can produce sharp short-term rallies in the yen. But previous rounds of intervention have shown that the effect often fades when interest-rate differentials remain wide. Without a narrowing of the U.S.-Japan yield gap, traders are likely to see yen strength after intervention as an opportunity to rebuild short positions.
The dollar remains a central force
The yen’s outlook also depends heavily on the U.S. dollar. If U.S. inflation remains firm and employment data stay strong, the Federal Reserve may keep rates higher for longer. That would maintain or widen the yield advantage of dollar assets, increasing pressure on the yen.
On the other hand, any clear sign of U.S. economic weakness or faster disinflation could shift expectations for American rate cuts. That would reduce the dollar’s yield advantage and give the yen some relief. For now, however, the rate gap remains large enough to keep the carry trade attractive.
This matters beyond Japan. The yen has long played a major role in global funding markets because of Japan’s low interest rates. When traders borrow yen to buy higher-yielding assets elsewhere, Japan’s monetary conditions are effectively transmitted into broader markets. A weak yen can therefore support demand for dollar-denominated assets while also strengthening the dollar’s position against other currencies.
That creates a headwind for assets priced against the dollar that do not produce yield. A stronger greenback tends to weigh on such markets because it raises the relative cost of holding them. It also tightens financial conditions across emerging markets and import-dependent economies.
What traders are watching next
The Bank of Japan’s next policy meeting on July 29-30 is now a key event for currency markets. Traders will be looking for any signal that officials are prepared to raise rates again, slow bond purchases more aggressively or tolerate higher government bond yields.
Language will matter. If the central bank suggests that inflation pressures require further tightening, the yen could find support. If officials emphasize uncertainty, fiscal risks or the need for gradual moves, the market may conclude that policy remains too cautious to defend the currency.
U.S. data will be equally important. Inflation, wages and employment reports could determine whether U.S. rates stay elevated. Any evidence supporting a higher-for-longer path would likely reinforce dollar strength and keep downward pressure on the yen.
The risk of sudden intervention also remains high. Traders should expect the possibility of sharp, unexpected moves, especially during low-liquidity trading hours. Tokyo may avoid giving clear warnings in advance if officials believe surprise is needed to maximize the effect.
Even so, the larger picture remains unchanged. Japan is facing a structural currency problem shaped by high debt, an aging population, persistent fiscal deficits and a wide global yield gap. Monetary policy alone may not be enough to reverse the yen’s decline.
Current levels near 162.62 may not represent the floor. Forecasts around 165 reflect a market view that Japan’s ability to defend the yen is constrained by fiscal reality as much as by central bank policy. Unless Japan moves toward fiscal consolidation, U.S. rates fall meaningfully, or global demand for dollars weakens, the yen is likely to remain under pressure through 2027.
