U.S. CPI lands at 21:30 JST (22:30 in winter), midway through Osaka’s 17:00–6:00 night session for Nikkei 225 futures. The night-session close is the key overnight anchor for where Tokyo’s 9:00 cash open will print — refined by the live futures level once Osaka’s day session resumes at 8:45. Here is the full transmission chain, release clock, and how to read the gap.
The BoJ raises rates not by draining reserves but by paying more on them: lift the rate on banks’ excess reserves and the overnight call rate follows almost mechanically. Here is the full plumbing — call market, TIBOR, lending rates, JGB yields, equities — with a step-by-step method for reading the September 2026 curve.
The Nikkei 225 rose 1.38% to 65,018.95 on Friday after the Bank of Japan raised rates 25bp to 1.25% on a 7-2 split. Markets read the move as dovish: the yen slid to 157.80, semiconductor names surged, and the TOPIX proxy actually fell. Short selling eased to 39.4% of turnover.
The Nikkei 225 closed up 0.33% at 64,136.25 on Thursday, surrendering most of an early 700-point surge as investors squared up ahead of Friday’s Bank of Japan decision and a long holiday weekend. The short-selling ratio held at 41.4% — elevated but within its recent band.
The Nikkei 225 shook off a soft US lead to close 0.69% higher at 63,923 on Wednesday, powered by energy and chip-equipment names, with the yen at 155 and the Bank of Japan decision two days away. Short selling ran at 41.5% of TSE turnover.
The Nikkei 225 closed all but unchanged at 63,484 on Tuesday as a 7.5% jump in SoftBank Group offset renewed semiconductor selling. The yen slipped to around 154.9 per dollar, the short-sell ratio eased to 39.9%, and all eyes turn to the Bank of Japan’s Sep 17-18 meeting.
Monday split Tokyo in two: the Nikkei 225 fell 0.81% as SoftBank Group plunged 10.7% on AI-slowdown headlines, while the broader TOPIX gained as financials and transport led 14 of 17 sectors higher. Short-selling sat at 38.1% of turnover — the calm end of its recent range.
The Nikkei 225 fell 1.93% to 64,011 on major SQ day as semiconductor names bore the brunt of a hot US PPI print and rising global yields. The TSE short-selling ratio climbed to 44.9%, the top of its recent range, while financials and autos quietly advanced.
The Nikkei 225 recovered from a near-1,000-yen intraday drop to close 0.20% higher at 65,270.95 on Thursday, led by banks on BOJ rate-hike talk. Short selling ran at 42.4% of TSE turnover, with a major SQ settlement due Friday.
The Nikkei 225 gave back a morning rally above 65,600 to close down 0.19% at 65,142.78 on Wednesday, as a firmer yen and Brent crude approaching $100 revived stagflation worries. Energy and steel led; retail and banks lagged. The TSE short-selling ratio stayed elevated at 44.2%.
