Nikkei 225 — daily market movers
Macro backdrop
The Nikkei 225 closed down about 1.9%, and the Topix fell 0.65%. Intraday the index dropped roughly 2.8% before rebounding to trim losses into the close. Three forces drove the session: (1) an oil spike — Brent crude topped $108/barrel, its highest since May, on U.S.-Iran tensions and supply fears — lifting inflation expectations; (2) rate-hike fears, with markets pricing a BOJ hike from 1.00% to 1.25% at the Sep 17-18 meeting (August wholesale/corporate-goods prices +7.6% YoY) plus ~71% odds of a Fed hike on Sep 15-16; and (3) a stronger yen (mid-153 to the dollar) pressuring exporters. High-beta semiconductors/AI and non-ferrous metals bore the brunt, while rate-beneficiary insurers rose.

Common Themes
Insurers dominated the gainers, taking three of the top ten (Dai-ichi Life, MS&AD, Tokio Marine) as the clearest beneficiaries of rising BOJ rate-hike expectations, since higher yields lift investment income. The rest were defensive and domestic/value names — LY, Olympus, Daiichi Sankyo, Bandai Namco, Kyocera — reflecting a rotation out of high-beta chips into rate-insensitive and rate-beneficiary sectors. Subaru's gain despite a stronger yen, and LY's rise, had no clear company-specific catalyst and look driven by sector rotation rather than fundamentals.

Common Themes
The losers were heavily concentrated in the semiconductor/AI supply chain (Kioxia, Advantest, SCREEN, ROHM, Ibiden, Lasertec, Toppan's photomasks, Resonac's chip materials) and non-ferrous metals/mining (Sumitomo Metal Mining, Mitsui Kinzoku). Rate-hike fears, oil-driven inflation worries and a stronger yen hammered high-beta growth, with regional chip weakness (Samsung -3.9%, SK Hynix -3.6%) adding pressure. Resonac fell roughly three times as much as its chip-material peers; beyond the sector move, that likely reflects oil pressure on its petrochemical arm and repricing ahead of its Oct 1 Crasus spin-off, but no single confirmed catalyst fully explains the magnitude.
Overall read
A textbook rates-up, inflation-shock rotation day: money moved out of high-beta semiconductors/AI and cyclical non-ferrous metals and into rate-beneficiary insurers and defensive, domestic names. This was not broad panic — the Topix fell only 0.65% and the index cut its losses sharply into the close — but a sector rebalancing driven by the oil spike and BOJ/Fed hike expectations, with growth and exporters pressured while rate-sensitive financials and defensives were bid.
