1.The Japanese yen has strengthened sharply toward 155.00 against the USD, driven by fundamental policy shift expectations rather than official intervention.
2.Japanese interest rate markets are pricing in nearly 50 bps of BoJ rate hikes by year-end and over 75 bps by mid-2027, backed by hawkish rhetoric from Governor Ueda and upside inflation risks.
3.Speculation regarding GPIF shifting asset allocation toward domestic holdings is providing additional structural support for JPY by potentially easing overseas capital outflows.
