The Bank of Japan lifted its policy rate by 25 bp to 1.0%, a move that was widely expected, and the decision drew one dissent from new board member Asada, who preferred to hold. It also confirmed that tapering of bond purchases will end in April 2027. The market reaction was muted, leaving the yen with limited near-term support.
The central bank maintained a bias towards further hikes but did not signal a faster tightening path. Despite the policy rate sitting at 30-year highs, Japan still has the lowest real rate in the G10, which keeps the yen in the frame as a funding currency unless the BoJ turns more clearly hawkish. Intervention risk was described as elevated with USDJPY just above 160, though warnings alone were framed as unlikely to trigger a sustained reversal.
Yen as a Funding Currency and USD/JPY Outlook
We see the Bank of Japan’s recent rate hike to 1.0% as a dovish tightening that doesn’t alter our outlook. With Japan’s latest core inflation figure at 2.8%, the real interest rate is a deeply negative -1.8%. This maintains the yen’s status as the prime funding currency for carry trades.
Our focus remains on being long USD/JPY, especially as the pair trades around 160.85 this morning. The wide interest rate differential, with the US Fed Funds rate holding at 4.0%, provides a strong tailwind for the pair to test higher levels. We believe the path of least resistance is still upwards without a more aggressive BoJ stance.
Derivatives Strategy and Managing Intervention Risk
For our derivatives strategy, we are favoring buying USD/JPY call options with strikes around 162 and 163 to capture further upside. The risk of intervention from the Ministry of Finance is significant, similar to the sharp but temporary reversals we saw in late 2022. This keeps implied volatility elevated, with the Cboe/JPX JPY Volatility Index ticking up to 11.5 this week.
To manage the downside risk from intervention, we are layering in some cheap, out-of-the-money put options. This provides a cushion against a sudden, sharp drop below the 158 level. This approach allows us to stay in the primary carry trade while defining our risk if officials decide to act.
