Bank of America predicts the Bank of Japan will maintain its policy rate at 0.5% during its 30–31 July meeting. They caution that current expectations for a rate hike, specifically in October, could be too optimistic.
Current market pricing suggests a 25% probability of a rate hike in September and 65% by October, which Bank of America views as overly aggressive. Despite a US-Japan trade agreement, the bank is expected to continue a cautious approach due to risks from ongoing tariffs and external demand issues.
Impact Of Dovish Surprise
There is a possibility of a dovish surprise, which could negatively impact the yen if the Bank of Japan provides little support for tightening expectations. The ongoing political uncertainty in Japan adds to the risk for yen bulls.
The Bank of America forecasts the Bank of Japan will remain dovish and advises caution against aggressive rate hike bets, particularly for October. This uncertainty may leave the yen exposed and potentially allow for further USD/JPY gains if the Bank of Japan falls short of expectations. The Bank of Japan’s announcements are expected between 0230 and 0330 GMT.
We expect the Bank of Japan will keep its policy rate at 0.5% as it concludes its meeting tonight. Market pricing for a hike by October seems overly aggressive, with a 65% probability baked in. This sets the stage for a potential repricing if the central bank maintains its cautious tone.
Recent data supports this cautious outlook, as Japan’s core inflation for June came in at 1.9%, still just shy of the bank’s target. This figure, combined with a slight GDP contraction in the first quarter, gives the BoJ cover to wait. Therefore, we do not expect any strong hawkish signals tonight.
Historical Precedent
We saw a similar situation back in 2024 after the BoJ ended its negative interest rate policy. The market priced in a series of rapid hikes that failed to materialize, causing significant yen weakness throughout that year. History suggests that betting against the BoJ’s tendency for caution can be a losing trade.
For derivative traders, this suggests a bearish outlook for the yen in the coming weeks. Buying call options on USD/JPY could be a strategic way to position for a move higher. This approach would benefit if the yen weakens as we expect, while also capping potential downside risk.
The risk of a “dovish surprise” is high, meaning implied volatility on yen pairs might be underpriced. If the BoJ offers little support for future tightening, we could see the USD/JPY pair, currently near 158, break above the 160 level. Traders could consider strategies that profit from both a rising spot price and an increase in volatility.
