Tokyo June 9, 2026 – Japan’s Finance Minister Satsuki Katayama has warned that Tokyo is prepared to take “decisive action” as the yen once again slipped into the lower 160 range against the U.S. dollar, reviving speculation of fresh intervention after record spending in May failed to stabilize the currency.
Mounting Pressure on the Yen
The yen’s decline to around ¥160 per dollar marks its weakest level since mid‑2024. In late April and May, Japanese authorities spent ¥11.73 trillion (US$73.2 billion) to prop up the currency, briefly pushing it back to the ¥155 zone.
That relief proved short‑lived, as widening interest rate differentials with the U.S. Federal Reserve continued to weigh on the yen.

Katayama’s remarks suggest that the government views the current threshold as a red line.
Tokyo previously stepped in when the yen breached 160, underscoring the symbolic and psychological importance of this level.
Government’s Balancing Act
Officials face a delicate policy dilemma. Intervention can slow volatility, but it does not address structural drivers such as the Fed’s higher interest rates compared with Japan’s ultra loose monetary stance.
Katayama stressed that Japan remains “increasingly in a position to take decisive action,” signaling that authorities are prepared to act again if depreciation accelerates.
The Bank of Japan, meanwhile, has been cautious about tightening policy, wary of derailing a fragile recovery.
That hesitation leaves fiscal authorities to shoulder the burden of defending the currency.
Economic and Market Implications
A weaker yen has mixed consequences. On one hand, it boosts the competitiveness of Japanese exports, offering relief to manufacturers.
On the other, it raises import costs, particularly for energy, and risks fueling inflationary pressures that erode household purchasing power.
For investors, the yen’s slide underscores persistent volatility in global currency markets.
Traders expect further turbulence unless the Bank of Japan signals a shift in its monetary framework.
Japan has a history of stepping into currency markets during periods of sharp depreciation.
Heavy interventions in October 2022 and July 2024 were triggered when the yen neared 160.
Analysts remain divided on the effectiveness of such moves, noting that interventions are costly and often provide only temporary relief without broader policy adjustments.
With the yen once again testing critical levels, Tokyo’s resolve will be closely watched.
The government’s readiness to act highlights the tension between currency stability and monetary independence, a balancing act that will shape Japan’s economic trajectory in the months ahead.
