The yen stayed weak against a firmer US dollar on Wednesday, pushing USD/JPY back towards a 40-year peak at 161.95. A wide gap between Bank of Japan interest rates and those set by other major central banks continued to weigh on the currency, blunting any support from Tokyo’s repeated warnings. Finance Minister Satsuki Katayama reiterated that Japan would “respond appropriately to currency moves at any time”, and her earlier online discussion with US Treasury Secretary Scott Bessent fuelled talk of co-ordinated action, though the market reaction proved limited.
With BoJ rates still comparatively low, the yen remains a favoured funding leg for carry trades, a dynamic that could strengthen if the Federal Reserve raises rates at least once this year. Reuters reported that former BoJ policymaker Sayuri Shirai said USD/JPY could climb to 165.00 should the Fed deliver that increase. Longer-term, the BoJ’s ultra-loose stance from 2013 to 2024 drove depreciation through policy divergence, while the 2024 shift towards unwinding has begun to narrow the gap between 10-year US and Japanese yields, alongside rate cuts elsewhere.
Persistent Negative Fundamentals for the Yen
The fundamental story for the yen remains overwhelmingly negative as of today, June 24, 2026. The key driver is the massive interest rate gap between the Bank of Japan’s rate, holding at 0.25%, and the Federal Reserve’s rate of 5.50%. This differential makes borrowing yen to buy dollars, the classic carry trade, an incredibly profitable and dominant market strategy.
We see this trend continuing, with the USD/JPY pair currently trading around 161.50. Recent U.S. economic data, including a May 2026 inflation report showing a sticky 3.5% CPI and strong jobs numbers, suggests the Fed has little reason to cut rates soon. In contrast, Japan’s inflation remains below target, giving the Bank of Japan no mandate for aggressive hikes.
While Japanese officials are increasing their verbal warnings, we must consider their past actions. Looking back at the massive interventions in late 2022, Japan spent over $60 billion, but this only provided temporary relief against powerful market fundamentals. We expect any intervention now would have a similar short-lived impact, creating a dip that would likely be seen as a buying opportunity.
Strategic Positioning: Options and Risk Management
Given this, we believe buying call options on USD/JPY is a prudent strategy for the coming weeks. This allows us to capture potential upside if the pair moves towards the 165 level, a target some analysts are now floating. It also caps our potential losses should the Ministry of Finance surprise the market with a sudden, large-scale intervention.
For those with more risk appetite, using futures to maintain a long USD/JPY position is viable, but requires careful risk management. The primary risk is not a change in fundamentals, but a sharp, unpredictable move driven by intervention. Therefore, any long positions should be protected with disciplined stop-losses to guard against that specific event risk.
