Japan Daily Briefing

SoftBank Group (SFTBY) surrendered most of its +6.8% semiconductor-driven rally from Wednesday's session, closing down 4.25% Thursday as the global bond rout reset risk appetite. The divergence with Tokyo Electron (TOELY, +0.80%) is the real story — TOELY is a capital-equipment name with direct exposure to leading-edge fab build-outs globally; SoftBank is an AI-narrative proxy. When bond yields spike, narrative proxies compress faster than hardware-cycle names with tangible order books. TOELY holding positive for a second consecutive session ahead of earnings is the semicap bull's best argument.

The US 30-year Treasury hitting 5.456% — a 22-year high not seen since 2004 — is the direct driver of Japan's bank and financial sector selloff. The BoJ normalization thesis (buy Japanese banks as JGB yields rise and net interest margins widen) runs into trouble when US long-end yields surge this fast: global portfolio flows rotate to US Treasuries, compressing the valuation re-rating thesis for Japanese financials. Mizuho (MFG) -1.86%, ITOCHU (IX) -2.30% and Tokio Marine (TKOMY) -2.41% are the day's financial-sector casualties — all three names with significant sensitivity to global rates.

Autos sector -0.73% significantly outperformed Banks/Financials -1.36% and Telecom -2.32% in Thursday's selloff, with Honda (HMC) actually closing fractionally positive. The read: Big Auto's FY2026 earnings cycle is being supported by strong North America demand and JPY weakness (USD/JPY above 155 makes Japan-manufactured exports more competitive in USD terms). The TSE prime-market governance reform narrative — which has boosted companies with PBR below 1x via buyback and capital return pressure — continues to benefit the auto complex more than BoJ-rate-sensitive names when global rates spike.
