Deep-dive analysis of Japanese yen currency trajectory and policy intervention. Article argues intervention may be temporary (sterilized, not tied to rate hikes), with realistic range 150–165 yen/USD through 2026. Key insight: yen strength may now signal economic recovery rather than crisis flight, changing its correlation with equity markets. Relevant for Thai investors with Japan exposure or FX exposure, though primarily macro-level analysis rather than actionable SME guidance.
