Federal Reserve Chair Kevin Warsh said he would not prejudge the October or December meetings, speaking at a fireside chat during the IMF and World Bank annual meetings in Bangkok. "At the Federal Reserve, we made very clear that we would deliver price stability, and we removed a dose of accommodation about a month ago," he said, referring to September's increase, per the Associated Press. On artificial intelligence he was optimistic about the productivity end state and blunt about the route, calling the path "very bumpy" and asking whether there are negative tail-side risks policymakers can act on, per CNBC.

A Fed chair volunteering financial-stability language in the same week an AI borrower's default insurance hit a record is not a coincidence, and it is the part Tokyo should read. For Japanese equities the base case has quietly become a Fed on hold into a BOJ that is building a case to move — the narrowest the two-way policy gap has been in this cycle, and the reason the yen stopped behaving like a pure carry instrument this week.

Nvidia chief executive Jensen Huang, speaking in Stockholm, said CoreWeave's "strength is improving every day" and that "their cost of capital is actually decreasing," rejecting the idea that the AI cloud provider — a major customer in which Nvidia is also an investor — needs any financial backstop from the chipmaker, per Bloomberg. The remarks came while CoreWeave's credit default swaps were setting records, per Yahoo Finance's report of the same comments.

Those sentences were the proximate reason Asian chip names rebounded on Friday. They are also a supplier vouching for a customer's balance sheet, which is the weakest form of credit assurance available and the one most likely to be tested. Tokyo's equipment makers are three steps down the same chain: their order books are written against data-centre construction schedules, and a meaningful share of those schedules is financed at double-digit yields rather than out of hyperscaler cash flow. A verbal reassurance moves the tape for a session. A refinancing at a tighter spread would move the order book.

South Korea's Kospi closed up 113.83 points, or 2.05%, at 5,668.05, breaking a seven-session losing streak after a 7.57% fall the previous day that triggered intraday circuit breakers. The index opened 1.8% higher, ran as far as 4.6% up intraday, then gave most of it back, per Seoul Economic Daily. Across the week it fell 14.5%, the largest weekly decline since October 2008, per the Korea JoongAng Daily.

Hold the two weekly numbers side by side: Korea down 14.5%, Japan down 5.37%. Both markets are long the same AI capex cycle, and the gap is almost entirely composition — Korea's index is a memory duopoly with retail leverage stacked on top, Japan's is an equipment complex inside a broad industrial index. That is a reminder about what the Nikkei actually is, and a warning that Japan's relative resilience this week was structural rather than a judgement that Tokyo's names are better owned.

Indonesian stocks suffered their steepest one-day fall since January 1998, dropping around 630 points, or 10.8%, after MSCI said it would consult on reclassifying the market to "standalone" status — a category below the "frontier" downgrade investors had been braced for — citing persistent concerns over transparency, ownership structures and suspected coordinated trading, per Reuters. The four largest banks fell between 8.5% and 14%, with Telkom Indonesia down 11.7% and Jasa Marga 14.8%. A final decision is due by 30 June 2027.

Standalone status removes a market from the emerging-market benchmark altogether, which converts every passive allocation into a forced sale on a known date. For Japanese investors this is a live exposure rather than an abstraction: Indonesia is one of the largest destinations for Japanese direct and portfolio investment in Southeast Asia, and the megabanks and trading houses carry the country risk in loan books and project equity, not in an index weight that can be sold.

The dollar index sat at 102.07, on track for a 0.14% weekly fall — its first in five weeks — lifting the euro off a 17-month low. The dollar was down about 0.2% on the week against the yen and shedding roughly 0.1% against the euro, per Reuters. The move came not from Fed repricing but from flight into Treasuries, where the US 10-year yield is set for its largest weekly fall in more than a year as investors reassessed whether data-centre operators reach profitability in time to service their debt.

The yen's gain this week was therefore borrowed rather than earned — it came from the American leg of the carry trade compressing, not from anything Tokyo did. That matters for how durable it is. A yen that strengthens because US yields fell will give it back the moment Treasury supply or a firm data print reverses the move, which is a very different proposition from a yen that strengthens because the Bank of Japan hiked.

Gross profits at PetroChina International, the state oil company's trading arm, are expected to top 20 billion yuan (about $3.0 billion) for 2026, a record, as refineries outside China capture wide margins in a tight global fuel market reshaped by the Iran war. By early October its crude division had more than doubled its full-year 2025 earnings, per Reuters. The structural reason is exposure: Hormuz accounts for just 10% of PetroChina's crude and gas requirements, against roughly half for domestic rival Sinopec.

That 10%-versus-50% split is the most useful energy number of the week, and it is the one Japan should be benchmarking against. Japanese refiners and utilities sit at the Sinopec end of that spectrum, which is why Tokyo's response has been subsidies for buying crude sourced outside the strait rather than trading profits earned from the dislocation. In an energy war, the winners are the buyers who diversified before it started.

Crude was heading for a second consecutive weekly advance as Middle East supply risk outweighed a fresh release of emergency reserves, with US Central Command confirming that a container ship which sank in the Strait of Hormuz this week was struck by an Iranian projectile. President Trump separately suggested lifting sanctions on some shadow-fleet tankers to bring down record freight rates caused by the squeeze on available tonnage, per Oilprice. The IEA's latest tranche covers the remaining 100 million barrels of the 400-million-barrel release agreed in March.

The freight line is the one with Japanese consequences. Record tanker rates are a cost that does not appear in the Brent price, is not hedged by anyone importing refined product, and flows straight into the kerosene and diesel bills the government is now subsidising. Releasing emergency barrels addresses the molecule. Nobody has a policy instrument for the voyage.

Taiwan plans to add AI servers and cutting-edge semiconductors to its controlled-items list, after which shipping restricted AI hardware to China becomes a criminal offence under the Foreign Trade Act, Economic Affairs Minister Kung Ming-hsin told Bloomberg, per Investing.com's report of the Bloomberg story. The change widens the net from a list of blacklisted companies — Huawei being the best known — to an entire country's customer base, and introduces criminal penalties for chip smuggling for the first time. It builds on January's US–Taiwan trade agreement, under which Taiwanese firms led by TSMC pledged $250 billion of US semiconductor investment.

Japan has run a parallel regime since 2023 through its own foreign-exchange law, covering 23 categories of chipmaking equipment. The difference is enforcement architecture: Japan's controls are administrative, Taiwan's are about to be criminal. When the two largest equipment and foundry jurisdictions in Asia converge on Washington's list, the residual question for Tokyo Electron, Advantest and Screen is no longer which tools they may ship, but how much of the China revenue currently in consensus models survives a regime where the rules stop being negotiable.

Tim Cook said Apple Intelligence has been approved in China and a test version arrives later this month, with live translation, writing tools and image clean-up but no Siri AI, in an interview with state-backed outlet The Paper in Shanghai, per Reuters. A consumer launch is planned for December with iOS 27.3, and the guardrails built with Alibaba include a filter giving the government approval over updates to the AI models.

The structure is the news: a Western AI product shipping into China with a state approval gate on model updates is a template, and the first one. For Japan's component suppliers the read-through is demand rather than politics — Murata (6981), TDK (6762) and Sony's (6758) imaging business are levered to iPhone replacement cycles in China, and an AI feature set that has been absent there for two years is exactly the kind of catalyst that converts an ageing installed base into upgrades.

Taiwan plans to develop a series of industrial parks in the United States costing between $2 billion and $4 billion each, starting with a Texas complex, to help smaller Taiwanese suppliers establish American operations around TSMC's fabs and Foxconn's AI server assembly, per Investing.com's report of the Bloomberg story. The government is partnering with the Taiwan Electrical and Electronic Manufacturers' Association to raise the funding, and will offer loan guarantees and regulatory assistance.

This is the step Japan has not taken. Tokyo has subsidised fabs on Japanese soil — Kumamoto, Rapidus in Hokkaido — on the theory that the ecosystem follows the anchor tenant. Taiwan is instead moving the ecosystem to where the anchor tenant went, which is the more honest reading of how semiconductor clusters actually form. If it works, the competitive question for Japanese materials and equipment suppliers in the 2030s is not whether America can build fabs, but whether it can build the 200 small companies that sit around each one.

Three legal experts who reviewed Meta's revised commercial terms at Nieman Lab's request said the terms, effective 30 October, could be used to argue that Meta may scrape content from websites "associated with" business accounts on its platforms — including news sites — and use it to train its AI products, with no opt-out: a business account that keeps using Meta's tools after that date has consented, per Nieman Lab. Separately, Accenture has told staff — some of whom had been spending as much as $1,000 a month — that it will now centrally fund only $29 per person per month on Claude, per 404 Media's memo report.

Put those two next to each other and you have both halves of the AI business model under pressure in the same week. Training data is being taken rather than licensed at the input end, while at the output end the largest professional-services buyer in the world has just set a price ceiling two orders of magnitude below what its own staff were voluntarily spending. Neither is fatal. Both argue that the revenue curves underwriting data-centre debt are softer than the contracted backlogs imply — which is the thesis that cost Tokyo 5% this week.

Japan's biggest songwriter announced a full international run for his GHOST tour, with dates in Seoul on 14 and 16–17 January, Singapore on 29 January, then Oakland Arena on 4 February, the Kia Forum in Los Angeles on the 6th, Mexico City's Palacio de los Deportes on the 9th, Newark on the 12th, Toronto on the 14th, London's O2 on the 24th, the Accor Arena in Paris on the 26th and Amsterdam's Ziggo Dome on the 28th, per Anime News Network. General sale opens on 22 October.

Ten years ago a Japanese-language artist filling the O2 and the Kia Forum on the same tour would have been a novelty booking. Yonezu is doing it on the strength of songs most of the audience first heard attached to an anime or a game, which is the quiet story of the decade in Japanese music export.

The towering pile of bean sprouts that defines Jiro-style ramen has become difficult to source, after a major Kanto producer, Saiki Shokuhin, suspended operations without warning in June and now appears to be shut for good. The number of bean-sprout producers in Japan has fallen from 235 in 2009 to 86 today, squeezed between fertiliser and fuel inflation and retailers who refuse price increases, per SoraNews24. Shop owners have been reduced to combing local supermarkets for stock.

The absurdity is the price. Bean sprouts have sold for under ¥100 a pack and sometimes as little as 19 to 28 yen, a figure that made them the cheapest vegetable in Japan and made growing them unsurvivable. Three decades of deflation taught shoppers that a pack of sprouts costs less than a canned coffee, and the industry has now been producing at a loss long enough that the correction, when it comes, will not be gentle.

Yokohama's Landmark Plaza and Mark Is complexes will run a Final Fantasy and Dragon Quest Christmas collaboration with Square Enix (9684) from 11 November to 11 January, with themed trees in both atriums, art panels and photo backdrops, a stamp rally running to 27 December, a "Slichoco Kitchen" pop-up café, two merchandise shops, ironing-bead craft workshops and seven exclusive art coasters showing the characters at Yokohama landmarks, per SoraNews24.

The official title — "Yokohama Minato Mirai Winter Holiday 2026 – Dragon Quest x Final Fantasy Interwoven Winter Fantasy" — is longer than some of the games' subtitles, which feels about right.

A digital stamp rally will run alongside the Friday Road Show and Ghibli Exhibition in Saga City from 3 November to 14 February, with four QR-code stops: the Saga Prefectural Art Museum, Saga Mado, the Saga Castle History Museum and the Saga Balloon Museum, each carrying a different film — From Up on Poppy Hill, Princess Mononoke and Nausicaä of the Valley of the Wind among them. The route covers about 2.9 kilometres, roughly 41 minutes on foot, and completing all four earns a commemorative badge, per SoraNews24.

Saga is one of Japan's least-visited prefectures. Four museums, one anime studio and a 41-minute walk is a more imaginative tourism strategy than most cities manage with ten times the budget.

Oriental Land (4661) and Disney have named the first Japan-based Disney Cruise Line vessel Disney Imagination, sailing from the Tokyo International Cruise Terminal from spring 2029, per The Japan Times. It will be a sister ship to the Disney Wish, modified for the Japanese market, at roughly 140,000 gross tons with about 1,250 staterooms, powered by liquefied natural gas and built by Meyer Werft at Papenburg in Germany, per Seatrade Cruise.

For the operator of Tokyo Disney Resort this is the first business in four decades that floats away from Maihama. The park's constraint has always been that it is one site with a fixed footprint; a ship is the first product Oriental Land has built that can go and find the customers instead.

Around 90 competitors gathered in Koka City, Shiga Prefecture, on Monday for the 43rd All-Japan Ninja Championship, held in a region historically famed as a hidden ninja village. The five disciplines included shuriken throwing, scaling a castle wall and a water sprint that required running across wooden boards floating on a pond, per TokyoReporter.

The pond did most of the eliminating. "Once you fall, you can't get back up on land. It was really difficult," one soaked competitor said; a first-timer admitted he had "totally underestimated it." The champion walked away with a menkyo kaiden — the traditional scroll certifying full mastery of a school — and a holiday in Australia.
