The Japanese yen fell more than 0.26% against the US dollar on Wednesday, leaving USD/JPY at 162.54 after touching about 162.03. The move followed the Federal Reserve’s meeting minutes, where most participants judged that “some policy firming would likely be warranted”, even as officials backed keeping rates unchanged and described the labour market as stable. Some participants also flagged scenarios in which prices could stay elevated, partly linked to AI-infrastructure demand, while views differed on whether policy was restrictive.
The broader tone was mixed after Donald Trump adopted a more hawkish stance on Iran, which supported the dollar and helped the US Dollar Index reclaim 101.00. Rate expectations implied an 18% probability of a 50-basis-point hike in September, while the odds of a 25-bps increase were near 52%. The 10-year US Treasury yield rose 1.5 basis points to 4.569%, aligning with the firmer USD/JPY. The pair held above 162.00, with 162.84 as a near-term threshold; beyond that, 163.00, then 165.00 and 170.00 were cited as further levels.
Fed Policy Outlook and Market Drivers
Given the Federal Reserve’s hawkish stance from its latest minutes, we see continued strength in the US dollar against the Japanese yen. The minutes confirmed that most officials feel further policy firming is likely needed to combat persistent inflation. We should therefore position for the USD/JPY to climb higher from its current level of 162.54 in the coming weeks.
This view is supported by recent strong economic data from the United States. The June jobs report showed the economy added a robust 255,000 non-farm payrolls, while the latest CPI data released this week shows headline inflation remains sticky at 3.4%. These figures give the Fed a clear mandate to consider another rate hike.
As a result, we see derivative markets now pricing in a greater than 75% probability of a 25-basis-point rate hike at the September meeting, according to the CME FedWatch Tool. This is a significant shift from just a few weeks ago and reflects growing market conviction in the Fed’s resolve. The odds of a larger 50-basis-point hike have also increased to nearly 20%.
The widening interest rate differential remains the primary driver for this currency pair. The US 10-year Treasury yield has pushed up to 4.65% in response to the Fed’s outlook, while Japanese 10-year government bonds yield less than 1.0%. This significant gap makes holding US dollars far more attractive than the yen.
Trading Strategies and Policy Divergence
From a trading perspective, we believe buying USD/JPY call options or selling JPY futures is the most direct strategy. A clear break above the July 1 high of 162.84 would open the path towards the 165.00 level. Beyond that, the psychological 170.00 mark becomes a viable medium-term target.
On the other side of the trade, the Bank of Japan has little room to act aggressively. With Japan’s own core inflation running below 2.0%, the BoJ is unlikely to accelerate its own policy normalization. This policy divergence will continue to weigh heavily on the yen.
However, we must remain vigilant for the risk of direct currency intervention by the Japanese Ministry of Finance. As we saw in 2022 and 2024, authorities become more vocal and eventually act when the yen’s depreciation is seen as too rapid. Any move towards the 165.00 level will significantly increase the chance of intervention, which could cause a sharp, albeit likely temporary, reversal.
Geopolitical tensions are also favoring the greenback over the yen at this moment. The recent hawkish tone from President Trump towards Iran is boosting the US dollar’s status as the ultimate safe-haven asset. This dynamic is overriding the yen’s traditional role as a haven in times of uncertainty.
