Tokyo’s Split Morning: Chip Stocks Drag the Nikkei as Energy Shares Rise

Market Snapshot

Data checked: October 26, 2026, 12:00 JST / October 25, 20:00 PDT. Quotes have different observation timestamps and must not be mistaken for synchronous morning closes.

At the 11:30 a.m. JST morning-session close, the Nikkei 225 stood at 62,214.66, down 478.50 points or 0.76% from Friday. Reuters separately reported TOPIX at 3,984.74, up 0.48%, at an earlier point in morning trading. That TOPIX observation is not a verified 11:30 a.m. morning close. Public reporting placed USD/JPY around 156.98 during the morning, while the benchmark ten-year Japanese government bond yield was reported near 2.810%. Both are observations, not daily closing values. For global context, Friday’s US Dow fell 652.82 points and the Nasdaq Composite lost 53.52 points.

What Moved Tokyo

The striking feature of the session was the distance between the headline index and the underlying market. According to a Japanese morning-close tally, Advantest alone subtracted 222.22 Nikkei points and Tokyo Electron another 198.22. Combined, they explain a large share of the 478.50-point decline, because the Nikkei is price-weighted rather than a straightforward measure of the total market value of every listed company. In Tokyo’s Prime market, 898 shares advanced, 601 declined and 48 were unchanged. A declining Nikkei thus coexisted with positive breadth and rising resource shares. Weak US equities and pressure on technology stocks shaped the opening, but did not cause uniform selling in Japan.

Today’s Market Mover

Advantest (6857) is the morning market mover. Its roughly 222-point negative contribution was the largest drag on the Nikkei, according to the published morning tally. The semiconductor-testing supplier sits at the intersection of Japanese manufacturing, the global AI investment cycle and expectations for the earnings of large US technology groups. It would be misleading to attribute its weakness to one unverified company-specific announcement: the available evidence supports the price impact more clearly than a precise single cause. Confidence: High in its index contribution; Medium in explanations of the wider investor positioning.

Sector Pulse

Twenty-two of the Tokyo Stock Exchange’s 33 industry groups rose in the morning. Mining, wholesale trading, petroleum and coal products, and real estate led the advance, while nonferrous metals, electric appliances and machinery were among the weak groups. Reuters reported earlier gains of 4.92% for oil producer INPEX, 4.56% for engineering company JGC Holdings and 4.28% for Mitsubishi Corporation. These were earlier intraday observations, not morning closing prices. High energy prices can raise the value of producers’ reserves even as they squeeze the margins of fuel consumers and Japan’s import-dependent households.

Yen Watch

Public morning reporting put the dollar near ¥156.98, compared with roughly ¥156.93 at Friday’s Tokyo market close. The difference was modest enough that describing the equity morning as simply a yen-driven selloff would obscure the semiconductor and oil divergence. A weaker yen increases the translated value of overseas earnings for some exporters, but makes dollar-priced energy and food more expensive for domestic buyers. A synchronized 12:00 p.m. FX tick was not independently established, so the currency level is explicitly labeled as an earlier reported quote.

Rates / JGB Watch

A reported 2.810% yield on the benchmark ten-year Japanese government bond was an intraday observation on Monday; Japan Bond Trading’s publicly listed October 23 closing yield was 2.800%. These are different timestamps, not conflicting closing figures. Higher yields can improve income on newly purchased bonds and potentially help bank margins, while raising funding costs for leveraged businesses and pressuring long-duration equity valuations. The interaction with energy-driven inflation is an especially important question ahead of the Bank of Japan meeting.

Global Handoff

At noon in Tokyo on October 26, the regular European and US cash sessions for Monday had not opened. This section therefore sets up the handoff rather than inventing one. Friday’s Wall Street session ended with the Dow at 52,215.16 and Nasdaq at 25,955.34, both lower. Oil retreated during Monday’s Asian session from elevated late-week levels amid reports of diplomatic efforts to reduce tensions in the Middle East. Whether that decline holds once Europe opens—and whether US technology earnings calm concern over the AI capital-spending cycle—will influence the next Tokyo session.

Policy / BOJ Watch

The Bank of Japan’s next monetary policy meeting is scheduled for October 29–30, with the October Outlook Report’s initial assessment due on October 30. The BOJ calendar also lists September’s Services Producer Price Index for October 27. Investors will look for evidence of how higher imported energy costs affect underlying domestic inflation, and whether wage and service-price trends support additional monetary tightening. No October policy decision has yet been issued; any suggestion otherwise would be premature.

Publisher’s Market Note

A single red index number can make an entire country look as though it had a bad morning. Yet most Japanese industry groups advanced. That contradiction is not a defect in the data; it is the story. Tokyo’s energy companies, chip designers, trading houses and households experience the same oil price through very different balance sheets. Markets become more illuminating when we look past the large number and ask who is paying, who is benefiting, and what remains uncertain.

Before the Next Open

This afternoon: watch whether Advantest and Tokyo Electron continue to dominate Nikkei index contributions, and whether positive Prime-market breadth survives the close. Overnight: monitor crude oil, US Treasury yields, US technology sentiment and the yen. Before Tuesday’s Tokyo session, check the BOJ’s scheduled services-price release. Ahead of October 29–30, track official Bank of Japan communication rather than attributing speculative decisions to policymakers.
