Nikkei 225 opens flat as Bank of Japan signals faster rate hikes

The Bank of Japan's own policy summary is now flagging upside price risks and a possibly faster path to rate hikes, which matters because it shifts the baseline assumption that kept Japanese equities in a low-rate comfort zone. A central bank signaling it may move sooner than expected is a direct pressure on valuations, particularly for debt-heavy companies.

Japanese government bond yields are already climbing in response to that expectation, reflecting how quickly fixed-income markets have repriced the policy outlook. Rising yields raise borrowing costs across the economy, and that transmission to corporate balance sheets tends to follow with a lag.

Reuters reports that nearly half of Japanese firms say rate hikes have already hurt them, giving this policy shift a concrete business impact well beyond market pricing. That figure means the damage is not hypothetical: a meaningful share of corporate Japan is already feeling tighter conditions before any additional moves.

The Nikkei 225 opening at 68,308 with zero net change from its previous close suggests the market is holding its ground for now, but the combination of a hawkish central bank summary, rising yields, and widespread corporate stress makes the calm open worth watching closely as the session develops.
