BOJ Rate Hike Fails to Meet Hawkish Expectations

The yen's vulnerability has increased as the Bank of Japan failed to meet hawkish expectations. The BOJ raised interest rates to 1.25%, but Governor Ueda did not indicate another move is imminent, leaving the basic rate differential problem intact.

This means that the Fed remains tighter than the BOJ, which could further weaken the yen. However, Japan's recent rate check and intervention campaign make it difficult to chase USD/JPY higher, especially around the 158-160 area.

The Tokyo holiday adds another layer of complexity, as thin liquidity can exaggerate yen weakness if traders continue fading the BOJ disappointment or magnify the impact of any official action. For now, intervention looks more like a constraint on the topside than the central trade itself.
