Yen Struggles After Bank of Japan Rate Hike

The BoJ voted 7-2 to lift its policy rate to 1.25%, effective Sept. 24, but Governor Kazuo Ueda offered no commitment to a rapid follow-up, saying the bank does not assume a specific pace for future hikes. For currency traders, that matters more than the hike itself: the yen needs a clearer tightening path to offset the dollar’s advantage, especially after the Federal Reserve’s own rate increase reinforced U.S. yield support.

Rabobank’s case rests on a slower-burn domestic recovery rather than one policy meeting. The bank points to stronger wages, including Japan’s 2.4% rise in real cash earnings in July, and to evidence that corporate reforms and Japan’s role in the semiconductor supply chain are helping sustain domestic inflation.

That gives investors a cleaner story than a simple rates trade. If wage gains keep feeding inflation and the BoJ continues to normalize, the yen can grind higher over time — but Friday’s reaction shows that markets want confirmation, not just another expected hike.

The setup leaves USD/JPY vulnerable to more two-way trading in the near term, with the dollar still backed by U.S. rate support and the yen depending on whether Japan’s wage and inflation improvement proves durable enough to force the BoJ to sound more aggressive at its next meetings.
