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, even as government bond yields and the yen moved lower. That combination can seem counterintuitive: a rate hike typically supports a currency and lifts yields. The market reaction instead reflected how the decision was framed — the increase was widely anticipated, and communication around the path ahead was read as measured rather than aggressive. When tightening is gradual and well flagged, the initial shock to asset prices tends to be limited.

For equities, the weaker yen matters because it flatters the overseas earnings of Japan's exporters when translated back into local currency. Lower long-term bond yields can also support valuations by keeping the discount rate applied to future corporate profits in check. Both forces can outweigh the modest drag from higher short-term borrowing costs, particularly for large, globally oriented companies.

What to watch: whether the yen's softness persists or reverses, how the central bank signals the pace of further moves, and whether wage and inflation data justify additional tightening. The durability of the equity rally likely depends on whether these drivers stay aligned.
