Why Japanese stocks rose as government bond yields and the yen fell after rate hike - CNBC

Japanese equities advanced after the Bank of Japan raised its policy rate, a move that might seem counterintuitive at first glance. The reaction reflects market expectations about the pace and scale of future tightening: investors appear to have read the hike as a measured step rather than the start of an aggressive cycle.

The yen weakened and government bond yields declined, which helps explain the equity response. A softer currency can support exporters by making their products more price-competitive abroad and by inflating the value of overseas earnings when translated back into yen. Lower bond yields, meanwhile, ease borrowing costs and make equities relatively more attractive compared with fixed income.

What to watch from here is whether the currency and yield moves persist, and whether the central bank's communication signals a slower or faster path ahead. For global investors, the episode is a reminder that rate decisions matter less in isolation than how they compare with what markets had already priced in.
