The Bank of Japan has lifted its policy rate by 25 basis points to 1.0%, a move that was widely anticipated and has not steadied the Japanese yen. Market focus has shifted towards the Federal Reserve, as broader G10 central bank decisions have failed to generate large foreign exchange moves, leaving USD/JPY driven more by US rate expectations than by Tokyo’s latest step.
The BoJ retains a tightening bias, but has not indicated a faster cycle, despite the policy rate being at 30-year highs. Japan still has the lowest real rate in the G10, which supports the yen’s use as a funding currency and can cap rebounds even after hikes. With limited near-term support from cautious BoJ positioning, the next leg for the yen is more likely to come from a clearer change in policy expectations, whether via a more dovish Fed outlook or a more hawkish BoJ stance.
Persistent Yen Weakness and the Role of US Rates
We are seeing the Bank of Japan’s recent rate hike to 1.0% get completely ignored by the market, with the yen continuing to weaken. The core issue remains the massive interest rate difference between Japan and the United States, which currently sits at over 3.5 percentage points. With USD/JPY now trading around a precarious 172, the focus for any potential yen strength has shifted entirely away from the BoJ.
The key catalyst we are watching now is the Federal Reserve, as the latest US CPI data for May came in at 2.8%, slightly below expectations. This gives the Fed room to adopt a more dovish tone in its upcoming statements. For us, this makes shorting USD/JPY an attractive strategy to position for a weaker dollar.
Positioning and Intervention Risk
In the coming weeks, we believe buying USD/JPY put options with a mid-July expiry is the most prudent way to act. This gives us direct exposure to a potential drop in the currency pair if the Fed signals a policy shift. At the same time, the defined risk of an option protects us if the yen’s weakness persists.
We must acknowledge that Japan’s real interest rate is still the lowest in the G10, which encourages using the yen as a cheap funding currency for carry trades. This powerful flow will cap any significant yen rallies that aren’t driven by a major change in US policy. The BoJ’s cautious stance simply isn’t enough to fight this trend on its own.
The risk of direct intervention by the Ministry of Finance is now extremely high, much like we saw back in 2022 and 2024 when the yen crossed previous psychological thresholds. Such a move would cause a sudden, sharp drop in USD/JPY, which would work in favor of our long put positions. This intervention risk provides an additional, albeit unpredictable, tailwind for our bearish outlook on the pair.
