Tokyo’s Nikkei 225 fell 647 points on Thursday to close at 68,309, handing back part of Wednesday’s rally as investors priced higher Japanese government bond yields and a dollar-yen rate still parked near 158 after the Bank of Japan’s September hike to 1.25 percent.

The session followed a Tankan report that confirmed sturdy manufacturer confidence but also showed services firms turning cautious on fuel costs. Foreign funds remained net buyers according to exchange filings published after the close, yet futures markets pointed to another cautious open heading into U.S. payroll data.

Bonds versus equities

The 10-year JGB yield hovered near levels last seen in the 1990s, keeping financial shares supported while pressuring long-duration growth names. Insurers and trading houses that benefit from a weak yen outperformed, while developers and utilities lagged.

Advantest and Tokyo Electron weighed on the Nikkei after overnight Nasdaq softness, even though Tankan capital spending plans pointed to continued semiconductor tool demand. Investors treated the chip pair as a global tech beta rather than a purely domestic capex story.

Currency as a second policy tool

Currency traders said verbal warnings from Japanese officials failed to lift the yen materially, leaving the BOJ as the market’s preferred stabilizer. A move toward 160 yen would revive intervention talk; a rebound toward 153 would squeeze exporter earnings already priced for weakness.

Options markets showed elevated demand for December yen calls, consistent with pricing a potential 25-basis-point hike at the BOJ’s year-end meeting rather than an October follow-up.

Flows and positioning

Proprietary desks reported light volumes compared with the September policy week, suggesting many accounts waited for U.S. labor figures before adding risk. Exchange-traded funds tracking the TOPIX saw modest inflows, a sign domestic pensions were still rebalancing toward equities despite the one-day drop.

Analysts at two global banks said the Nikkei’s 4 percent gain in September left room for profit-taking even if earnings revisions stay positive. They pointed to December as the more likely window for the next policy rate move, citing Ministry of Finance comments in the BOJ’s September opinion summary.

Friday watchlist

Investors will track overnight oil moves after Middle East supply headlines, along with any pre-weekend rhetoric on currencies from Tokyo. A calm yen session could let exporters stabilize the index even if yields stay elevated.

Sector rotation

Real estate investment trusts underperformed for a third session as financing costs rose, while trading houses with Middle East energy exposure posted gains. Retail investors on margin accounts cut borrowed positions according to exchange weekly data released Friday morning.

Cross-asset flows

Life insurers trimmed duration in afternoon dealing after the 10-year yield held above 1.05 percent, according to two Tokyo desk heads. Banks that had leaned on negative carry for years now pitch floating-rate loan books to regional borrowers, a product push that only works if policy rates stay elevated through the fiscal year.

Foreign investors sold ¥820 billion in Japanese equities on a four-week net basis, exchange data through Thursday show, even as the Nikkei held a 68,000 handle. That divergence suggests overseas funds are booking profits on yen weakness while domestic accounts buy dips on Tankan optimism.

BOJ officials repeated in a Friday speech that gradual normalization continues, but they warned that oil above $100 could re-accelerate import prices before wage deals fully feed household budgets. Equity strategists said the next test is whether September machinery orders, due mid-month, confirm the Tankan’s capex line.

Trading desks said Friday’s late dip in futures was modest compared with August’s volatility spike, when the yen carry trade unwound in hours. Pension funds rebalanced toward domestic bonds at month-end, a flow that can exaggerate yield moves even when the BOJ holds steady.
