📉 Nikkei futures collapse 7% as SFTBY crashes 14.4% — Japan's tech complex bears the full brunt of Democrat-driven AI selloff

Japan's equity session was a 'kuro-kin (Black Friday)' mirror of Wall Street's historic AI rout: Nikkei 225 futures plunged 7% at open with SoftBank Group (SFTBY) down 14.4% and Hitachi (HTHIY) off 10.1%, as the Democrat midterm sweep triggered data centre regulation fears that cut deep into Japan's tech supply chain. Sector carnage was broad — Electronics -3.58%, Industrials -5.10%, Telecom -7.28% — with only Banks (+0.07%) and Pharma (-0.90%) offering relative shelter. SONY fell 2.0% and Kyocera (KYOCY) lost 7.9%. The iShares MSCI Japan ETF gained 0.65% by US close, suggesting some recovery from intraday lows as chip stocks rebounded globally, but the intraday narrative was set at open: Japan's Vision Fund exposure, semicap supply chain, and industrial tech complex were all mispriced for a world where Democrat-majority Congress votes on data centre construction permits.

Asian stocks slump after US tech rout on AI regulation fears

DW reported that concerns about Democratic push-back on data centre projects are weighing on the AI trade globally, with Asian markets seeing simultaneous selloffs in Japan, Korea, and Taiwan. This is the first time in the current AI bull cycle that a US political event — not earnings or macro — triggered a synchronized Asian tech selloff. For Japan, the 7% Nikkei futures plunge at open was the most acute expression of this new political risk premium.

Nikkei futures plunge 7% as Japan capital flows surge

Stock Market Watch reported Nikkei 225 futures collapsing 7% in early Friday trade — a dramatic sell-off reflecting the full transmission of the US tech rout into Japan. The 'capital flows surge' detail is counterintuitive: even as prices fell, trading volume surged as institutional portfolios rebalanced their Japan tech allocations. SoftBank's Vision Fund II portfolio, with concentrated US AI infrastructure names, is the highest-beta Japan vehicle to Democrat data-centre regulation concerns.

Japan's US midterm read: Trump defeat and yen implications

Toyo Keizai Online's analysis of the US midterm results for Japan highlights a key strategic question: how does Japan calibrate trade and security policy toward a Democrat-led Congress post-Trump Republican defeat? For markets, the near-term transmission is USD/JPY — falling US yields (bonds rallied as risk-off) narrow the Japan-US rate differential, strengthening JPY and pressuring export names (Toyota, Sony) even as global tech selloff dominates the tape.

Smart-money note

SFTBY -14.4% in one session signals the full repricing of SoftBank Vision Fund's AI portfolio under a Democratic regulatory scenario — fund NAV estimates need to come down if US data centre permitting slows. HTHIY (Hitachi) -10.1% and KYOCY (Kyocera) -7.9% are industrial components suppliers to semiconductor fabs and AI server assembly; these moves tell you the market isn't just pricing a Nvidia-level revenue slowdown, it's pricing a physical construction delay for the facilities these companies equip. BoJ's silence on FX is notable: USD/JPY has historically attracted intervention talk when equity markets stress, but falling US Treasury yields are compressing the Japan-US rate spread in a JPY-strengthening direction — no intervention trigger. The key signal for next week: Tokyo Electron and Advantest earnings guidance. If the HBM memory cycle is intact (Samsung and SK Hynix both pre-sold 1-3 years of supply), the semicap equipment suppliers will say so explicitly in their Q3 guidance. That's the real floor-finder for Japan's tech complex.

What to watch tomorrow

USD/JPY level

USD/JPY direction governs export-name sentiment. BoJ watching below 148; above 155 triggers intervention rhetoric. A narrowing Japan-US spread means JPY strengthens, hurting Toyota and Sony's USD earnings.

Tokyo Electron & Advantest

Semicap bellwethers report next week. HBM cycle integrity will be confirmed or denied here — their guidance is the clearest read on whether Japan's tech rout overdid it or priced correctly.

SoftBank Vision Fund NAV

Vision Fund II's US AI portfolio marks will come into focus as management presents Q2 results. Any admission of downward marks on US data centre names = further SFTBY selling.
