Tokyo Reverses a Second
Morning Selloff

1 · Market SnapshotTokyo turned an early loss into a broad first-half gain

Tokyo stocks rose as lower oil and U.S. Treasury yields brought buyers back after an early chip-led decline, while a firmer yen and Nvidia’s looming results framed the afternoon.

The Nikkei 225 opened 251.94 points lower at 65,604.49 even after Wall Street had advanced overnight. Profit-taking hit parts of the semiconductor complex, and the opening tape looked like a continuation of the caution that had dominated the previous morning. It did not last. Advantest and SoftBank Group reversed, short positions were covered, and the average crossed into positive territory before finishing the first half at 66,227.55, up 371.12 points, or 0.56%. Estimated volume was 875.28 million shares.

TOPIX told the sturdier breadth story. It opened 2.68 points higher and reached 4,118.44 at lunch, a gain of 24.77 points, or 0.61%. A market-cap-weighted index outperforming the price-weighted Nikkei suggests that the recovery reached beyond two heavyweight contributors, although the sector map remained uneven.

2 · What Moved TokyoTwo recoveries, with different catalysts inside the same trade

August 25 final: from below 65,000 to a positive close

The Nikkei fell as low as 64,609 on Tuesday, more than 900 points below the prior close, as weak U.S. technology trading spilled into Japan. The selling eventually met a rebound in chip and AI-linked shares and a futures-led squeeze. The index closed at 65,856.43, up 328.34 points, while TOPIX finished at 4,093.67, up 20.38. Both gained exactly 0.50%.

Tokyo Electron ended 0.47% higher and Kioxia gained 0.65%; Advantest still closed 0.14% lower after cutting a deeper loss. That detail matters: Tuesday’s close was a recovery from stress, not a clean all-day risk rally.

August 26 first half: cheaper oil and lower rates soften the macro backdrop

Wall Street supplied a more supportive handoff. The Dow gained 160.24 points to 53,577.40, the S&P 500 added 24.42 points to 7,677.28, and the Nasdaq Composite rose 171.11 points to 26,151.30. WTI crude fell 3.12% to $82.36 and the U.S. 10-year Treasury yield dropped about eight basis points to 4.625%.

That combination reduced two immediate pressures on Japanese equities: the import-inflation threat from oil and the valuation drag from higher global discount rates. Yet it was not universally bullish. Lower crude weighed on petroleum and coal-product shares, and easing Middle East fears hurt shipping and energy-linked expectations even as they improved the broader macro mood.

3 · Today’s Market MoverAdvantest carried the index without a sector-wide chip rally

The designation “market mover” refers to explanatory power, not merely the biggest percentage gainer. Because the Nikkei is price-weighted, a move in a high-priced constituent can reshape the headline average. Advantest’s rebound helped turn the index while Tokyo Electron, Kioxia, TDK, Lasertec and other technology names remained lower.

That divergence is the heart of the session. Investors were not buying every semiconductor name indiscriminately. They were selecting exposure before Nvidia reports in the United States on Wednesday. A strong outlook could validate the positioning; a disappointment could make the same index concentration work in reverse. No fresh Advantest disclosure independently located for this report explained the morning move, so this edition does not attribute the gain to corporate news.

4 · Sector PulseFinancials and drugmakers rose; shipping and oil-linked groups fell

Leaders: securities and commodity futures, pharmaceuticals, and banks. Chugai Pharmaceutical, Daiichi Sankyo, Otsuka Holdings, Astellas Pharma and Tokio Marine were among the advancing large names. This defensive-financial mix helps explain why TOPIX edged ahead of the Nikkei in percentage terms.

Laggards: marine transportation, petroleum and coal products, and metal products. Within technology, Tokyo Electron, Kioxia, Taiyo Yuden, TDK, Ibiden, Lasertec, Screen Holdings and Disco were among the decliners.

The phrase “risk-on” therefore conceals more than it reveals. The market bought banks and drugmakers, sold oil-linked groups and numerous chip names, and still pushed the benchmark higher through a few large contributors. The afternoon test is whether breadth persists or trading narrows as investors wait for Nvidia.

5 · Yen WatchThe yen strengthened, but not enough to rewrite exporter assumptions

USD/JPY moved down from 159.26 to 158.88 during the Tokyo morning. Reports linked the softer dollar to lower crude and reduced concern about an immediate escalation in the Middle East. EUR/JPY traded between 185.45 and 185.91, while EUR/USD held a narrow 1.1666–1.1676 range.

A firmer yen can reduce imported costs while diminishing the yen value of overseas earnings. But a 38-sen morning move does not by itself change corporate planning assumptions, and the currency remains historically weak near 159 per dollar. The useful afternoon signal is whether USD/JPY reclaims 159 or begins to settle below it.

6 · Rates / JGB WatchBonds caught the U.S. rally, then met Japan’s fiscal arithmetic

The benchmark 10-year JGB yield was 2.880% at 11:00, down one basis point from Tuesday. September JGB futures were two sen higher at 126.50. Lower U.S. yields and cheaper oil supported Japanese bonds early, but a report that debt-servicing requests for the fiscal 2027 budget would reach a record restrained the advance.

One basis point of relief should not obscure the regime. Ten-year yields reached the 2.9% area in August and remain close to 3%, levels unseen for decades. The higher income has attracted record 2026 inflows to Japan-focused bond ETFs, including European demand, while the same yields raise government financing costs and challenge equity valuations.

7 · Global HandoffWhat Europe and the United States inherit from Tokyo

Tokyo passes three messages westward. First, falling oil and Treasury yields are improving the macro setup. Second, Asian investors are still reluctant to commit before Nvidia. Third, Japan absorbed another morning selloff, but the chip trade underneath the benchmark is split.

U.S. equities ended Tuesday higher—the Dow by 0.30%, the S&P 500 by 0.32%, and the Nasdaq by 0.66%—while Europe’s STOXX 600 gained 0.35%. Oil’s further decline in Asian hours eased inflation anxiety, but it also reflected a fast-changing geopolitical premium. The next durable signal must come from earnings, U.S. inflation data or both.

8 · Policy / BOJ WatchServices inflation accelerated, keeping the BOJ debate alive

Japan’s Services Producer Price Index rose 3.6% in July from a year earlier, accelerating from a revised 3.4% in June. The measure tracks what companies charge one another for services. Its persistence suggests that labor and other costs are being passed through beyond the goods sector.

Markets are debating the timing of the Bank of Japan’s next rate increase, but one 3.6% print does not settle the decision. Policymakers must weigh wages, consumption, the weak yen, imported inflation, JGB market conditions and geopolitical effects together. This report records the data and the market debate; it does not describe a September increase as certain.

9 · Publisher’s Market NoteA rebound is evidence, not a verdict

Two consecutive morning reversals tempt a tidy conclusion: buyers have found a floor. The evidence is narrower. Selling lost force around 65,000, and money returned to selected AI-linked heavyweights and futures on both days. That is useful information about positioning, not proof that valuation risk has disappeared.

August 26 is also an event day. A rally built partly on expectations for Nvidia can only be separated from short-covering after the company reports. The journalistic task is to preserve that distinction: breadth versus concentration, a verified catalyst versus inferred positioning, and a midday gain versus a final close.
