Why Japan’s markets flipped the usual script after central bank rate hike - CNBC

Japan's markets responded to the Bank of Japan's latest rate hike in a way that defied the usual playbook. Normally, higher interest rates strengthen a currency by making domestic assets more attractive. This time, the yen weakened even as the BOJ raised rates, a reaction that caught many observers off guard.

The explanation lies in expectations rather than the decision itself. Markets had likely priced in the hike well in advance, so the surprise came from the central bank's guidance and the pace of future tightening. If investors read the move as cautious or gradual, the rate differential with other major economies can still favor the yen as a funding currency, keeping pressure on it.

For global investors, the episode is a reminder that rate decisions matter less than the gap between what markets expect and what policymakers deliver. What to watch next: the BOJ's communication on future hikes, Japanese bond yields, and whether currency moves start to feed into inflation or corporate earnings.
