Japan Daily Briefing

Japan's MoF + BoJ intervention on July 31 was ¥5.33 trillion — confirmed via BoJ current-account residual analysis (Toyokeizai sourced). This is the coordinated US-Japan FX action: Bessent posted explicitly that the US would not hesitate to participate in further coordinated intervention. The USD/JPY move from above 156 to intraday prints at 155-low is the direct consequence. For Nikkei-exposed investors, every 1% of yen appreciation translates into approximately 0.8-1.0% earnings headwind for auto/export-heavy names. The intervention signals the floor — MoF's preferred range appears to be 155-158 for USD/JPY near-term. Breaking below 155 cleanly is the next bear trigger.

KYOCY (Kyocera) -4.91%: the precision ceramics and electronic components maker has high USD-revenue exposure; yen strength compresses yen-reported margin. TOELY (Tokyo Electron) -3.53%: the semicap bellwether's capital equipment revenues are global (billed in USD/EUR) but reported in yen — every yen appreciation cycle compresses the yen-reported top line. This is the most significant signal in the session: Tokyo Electron weakness ahead of earnings season means semicap investors are de-risking even before formal guidance cuts. NTTYY (NTT) -3.27%: international business USD exposure, same dynamic. MUFG +0.22% and SoftBank +0.20% were small survivors — MUFG benefits from BoJ normalization trajectory (higher domestic rates = NIM expansion), SoftBank's USD-denominated assets create a partial USD-strength hedge.

The US-Japan yen intervention has traders glued to one trade. USD/JPY at 155 is the current intervention floor; MoF's revealed tolerance for yen strength is approximately 154-155 (they intervened above 160+ before, and the 156-157 move triggered July 31 action). If USD/JPY breaks cleanly below 154, the market reprices toward a structural yen-appreciation cycle — that is a Nikkei 35,000 scenario from current 38,000-39,000 levels. BoJ's silence on further tightening provides the buffer: the central bank is doing FX intervention without hiking aggressively, which contains the JGB yield spike risk. TSE Prime Market governance reform stocks (PBR<1 names, corporate buyback candidates) are less affected than exporters — the domestic corporate reform story is independent of FX.
