U.S.-China Relations
NextFin News - Asian stocks rose on Wednesday, extending a technology-led advance set off by a record close on Wall Street, while a three-hour US-Iran diplomatic contact in New York opened the first credible path toward de-escalation in a seven-month war. The two forces pushed crude oil to its lowest level in 12 days and let bond yields and the dollar firm on a separate, unwelcome message: the Federal Reserve is not done hiking.
The tension of the session is not whether markets rose — they did, with Taiwan's Taiex touching a record and South Korea's Kospi jumping more than 2 percent at the open — but what is underwriting the move. Two fragile premises are doing the work: that artificial-intelligence demand is reaccelerating, and that US-Iran diplomacy can hold. The Fed, by contrast, is signaling that it is still tightening.
The Rally and the Contact: What Happened
Wall Street's rally began on Monday, when the S&P 500 advanced 1.5 percent for its strongest session since August 4 and the Nasdaq Composite surged 2.3 percent to its first record close since June. The Dow Jones Industrial Average gained 366 points, or 0.7 percent. Artificial-intelligence and semiconductor names led: Meta Platforms jumped more than 11 percent after its free AI agent, Muse, rose to the top of mobile app download charts; Intel surged 12 percent; AMD added about 10 percent and briefly reached a $1 trillion market valuation; Nvidia rose 2 percent; Corning gained nearly 6 percent.
Asia followed. Taiwan's Taiex climbed to a record before paring most of the advance; South Korea's Kospi opened up more than 2 percent and finished modestly higher; mainland China's CSI 300 advanced around half a percent; Hong Kong's Hang Seng and Shanghai Composite posted modest gains; Australia's S&P/ASX 200 edged higher. The MSCI Asia Pacific excluding Japan Index jumped as much as 1.5 percent before giving back about half. Japan's cash market remained shut through Wednesday for the Silver Week holidays, leaving Tokyo facing a volatile reopening on Thursday.
Alongside the tech bid, a diplomatic development carried outsized weight. President Donald Trump told reporters at the UN General Assembly that US officials had held a three-hour meeting with an Iranian delegation on the sidelines of the 81st General Debate.
They had a very good meeting, very productive meeting, and they have another one scheduled in the very near future.
The contact was conducted by envoys Steve Witkoff and Jared Kushner, with Qatari Prime Minister and Foreign Minister Sheikh Mohammed bin Abdulrahman Al Thani present for much of the session, and Iranian Foreign Minister Abbas Araghchi leading Tehran's side. Witkoff later described the discussions as "promising" and "constructive," while Iranian state television confirmed Araghchi met Witkoff "at the insistence of the American side" and conveyed Tehran's conditions.
The talks moved the Strait of Hormuz to the center of the negotiations. Tehran's conditions for reopening the waterway include lifting the US naval blockade, releasing frozen Iranian assets, and ending the war across all fronts. A senior Iranian official said Tehran could reopen the strait within seven days if Washington eased military pressure and lifted the blockade on Iranian ports.
Oil sold off on the prospect. West Texas Intermediate crude fell to its lowest level in 12 days, trading near $90 a barrel, while Brent dropped below $100. The decline was compounded by reports of a gradual restoration of Saudi export infrastructure. Gold, which had been trading near record territory above $4,300 an ounce, slipped about 0.6 percent toward $4,320 as hawkish Federal Reserve commentary lifted the dollar and rate expectations.
That is the fork this rally must navigate: risk assets are pricing de-escalation and AI growth, while the bond market is pricing more tightening. Both cannot be comfortably right for long.
Why AI News Moves the Whole Market
The immediate read is simple: good AI news lifts chip stocks, chip stocks lift the Nasdaq, and a rising Nasdaq lifts everything. That is true as far as it goes, but it stops at direct causality. The mechanism that matters runs through the discount rate and the earnings-revision cycle at the same time.
When Meta's Muse topped download charts and Alibaba unveiled what it called China's most powerful AI chip, investors were not merely celebrating two products. They were repricing the probability that the AI capital-expenditure cycle, which had shown signs of fatigue, is entering a second leg. Alibaba's chief executive, Eddie Wu, rolled out the Zhenwu V900 processor at the company's flagship conference in Hangzhou, calling it "the most powerful AI chip in China today" and claiming three times the performance of the prior-generation Zhenwu M890. He set a target of 20 gigawatts of global data-center capacity for Alibaba Cloud by 2032 and reiterated a three-year AI spending commitment of more than $53 billion.
Last year, we asserted that the more capable AI becomes, the more powerful humanity will be. Today, I remain steadfast in that conviction.
That matters for US equities because the AI trade is a two-sided market. On one side sit the US designers and equipment suppliers; on the other sits the build-out of capacity in China, which consumes the same advanced packaging, memory, and power infrastructure. A reacceleration on the Chinese side reduces the risk that the global AI capex cycle peaks in 2026. It also explains why Taiwan's Taiex, home to the contract manufacturers at the center of that supply chain, returned to a record even as US-China tensions remain unresolved.
The second-order effect runs through the discount rate in the opposite direction. A rally in long-duration growth stocks is normally helped by falling yields. This time, yields are not falling — the 10-year Treasury yield was around 4.97 percent, up more than a basis point on the session, and the dollar index was up 0.17 percent to 100.59. The rally is therefore being carried by earnings revisions, not multiple expansion. That is a sturdier foundation than the rate-driven melt-up of 2024, but it is also a narrower one: it requires the earnings story to keep landing.
The Fed Counterweight: A Central Bank Still Hiking
The Federal Reserve raised its policy rate by 25 basis points on September 16, to a target range of 3.75 percent to 4 percent, and Chairman Kevin Warsh has flagged more hikes in the coming months. The market has listened. According to the CME FedWatch Tool, traders saw a 92 percent chance of a rate hike in December, up from 80 percent the prior week. Prime Terminal data put the probability of a 25-basis-point hike at the October 28 meeting at 53 percent, with December at 90 percent.
The messaging from policymakers has been consistent. St. Louis Fed President Alberto Musalem said in an interview that persistent demand and recurring supply forces are keeping inflation risks elevated.
I judge that without further policy restraint on inflation it is more likely to be substantially above our 2% target in 18 months than at target.
Chicago Fed President Austan Goolsbee, noting that inflation peak forecasts have repeatedly slipped from late 2025 into 2027, put it bluntly: "the only way back is the hard way."
This is the clearest divergence in the cross-asset picture. Equities are rallying on growth optimism; the bond market is pricing a central bank that still sees inflation as unmet. Historically, that divergence resolves in one of two ways: either the Fed blinks as data weakens, which would be bullish for duration assets and gold, or inflation proves sticky and the Fed follows through, in which case today's equity multiples face a second leg of compression.
Gold's behavior is the tell. The metal has held remarkably firm near $4,300 an ounce despite a stronger dollar and rising real yields — a sign that a layer of buyers is treating it as a hedge against fiscal and geopolitical risk rather than as a pure inflation hedge. But firm is not the same as rising. A follow-through on the Fed's hiking path, with core inflation printing at or above 0.3 percent month over month for two consecutive months, would likely test the $4,200 support zone and drain liquidity from the very equities leading this rally.
Oil and the Diplomacy Discount: Cyclical Relief, Not Structural Peace
The oil move is the cleanest expression of the de-escalation trade, and it is also the most fragile. WTI falling near $90 and Brent below $100 reflects two distinct drivers: a real supply development, the gradual restoration of Saudi export capacity after recent disruptions, and a speculative one, the prospect that US-Iran diplomacy can hold.
The supply driver is structural in the narrow sense that barrels are coming back. The diplomacy driver is cyclical and reversible — and the reversibility is priced at zero. The same day Trump described the meeting as productive, he warned the US might strike again: "We may have to blow up another one, Pickaxe Mountain. We're not seeing a lot of activity there, but if we do, we'll blow it up immediately." Iran's parliament advanced provisions allowing authorities to seize 20 percent of the cargo or its value from ships found to have violated Iranian passage rules, and Deputy Speaker Ali Nikzad said negotiations are now tied to Hormuz and that Iran would "not back down" over the strait.
The IRGC spokesperson, Hossein Mohebbi, said the force does not reject diplomacy but views negotiations as a way to impose Iran's conditions. That is not a peace process; it is a bargaining position backed by a blockade. The market has taken a 12-day-low oil print from it. If the next scheduled meeting fails to produce a tangible opening on the blockade or frozen assets, the diplomacy discount can evaporate as fast as it appeared — and with it, the relief that has flowed into Asian energy importers' equity markets.
Cyclical or Structural: The Call This Rally Depends On
The right framing is that two different forces are at work, and they point in opposite directions across time horizons.
The AI leg of the rally is structural. The evidence is in the capital commitments, not the stock prices: Alibaba's $53 billion three-year plan, its 20-gigawatt 2032 capacity target, and the fact that the Zhenwu V900 can be clustered in groups of up to 500,000 units to train frontier models. This is a capacity race between two blocs, and capacity races do not reverse on their own. The constraint is no longer whether AI will be built; it is power, packaging, and memory. That favors the suppliers of those bottlenecks over the pure application layer.
The de-escalation leg is cyclical. It rests on a single channel — the reopening of Hormuz and the easing of a naval blockade — and it is mean-reverting by construction: if talks stall, the strait closes again, and the premium returns. Three historical-cycle comparisons make the point. Oil spiked on the 2019 tanker attacks in the Gulf of Oman and gave back the gains within weeks as tensions cooled. It spiked again on the 2022 invasion of Ukraine and retreated as alternative flows were established. It spiked in 2024 on Red Sea disruptions and faded as routing adjusted. Each time, the market priced a structural rupture that proved cyclical. This episode fits the same pattern: a diplomatic opening, however tentative, is enough to unwind a war premium that was never fully embedded in the price.
The Fed leg is the wildcard that straddles both. If the tightening cycle is structural — a multi-year response to a post-pandemic inflation regime — then the rally is fighting the tide. If it is cyclical — a front-loaded response to supply shocks that will fade as energy normalizes — then the Fed will blink first, and the rally has room to run. The data point that separates the two is core services inflation over the next two prints.
The Adversarial Case: What If the Market Is Right?
The strongest counter-thesis is not that diplomacy will fail or that AI is a bubble. It is that the market is correctly reading a preventive, not reactive, Fed — and that the divergence is a feature, not a bug. In this reading, the Fed is hiking precisely because demand is strong enough to absorb it. Strong demand is what is driving the AI capex cycle, and a central bank that tightens into strength is signaling confidence, not fear. Under that interpretation, the equity rally and the hiking cycle are two expressions of the same underlying reality: an economy growing fast enough to fund a $53 billion AI buildout and still service higher rates.
That case has a named advocate in the Fed's own messaging. Goolsbee's acknowledgment that supply shocks complicate the policy response, paired with his insistence that the response cannot be ignored, is the language of a central bank trying to normalize without breaking growth. If the Fed succeeds in that narrow path — hiking enough to cool inflation but not enough to tip demand — then today's cross-asset divergence is the calm before a synchronized advance.
The falsifying signal is specific and observable. If the unemployment rate rises by 0.3 percentage points or more over two consecutive months while core PCE holds at or above 0.3 percent month over month, the "hiking into strength" thesis breaks: that is stagflation, not normalization, and it would force the Fed to choose between inflation and employment. In that scenario, the equity rally loses its earnings anchor and the bond market wins.
What to Watch, and Who Is Exposed
The short-term read is constructive. Positioning into the rally was bearish — Citi Research noted unusually bearish positioning across the Nikkei and Kospi, which creates scope for short-covering — and the catalysts are fresh. The Trump-Xi summit on Thursday is expected to put artificial intelligence at the top of the agenda, with a US-proposed notification mechanism for AI incidents and a Treasury-backed channel to exchange information on AI development. US and Chinese officials held preliminary AI and trade talks in New York on September 21, and a senior US official accused China of failing to fully implement its pledge to ease supplies of critical minerals. Any joint language on AI guardrails would be read as a risk-on signal for the semiconductor supply chain.
The medium-term read is conditional. The rally holds if two things land: AI earnings revisions continue to beat, and the next two inflation prints do not force the Fed's hand toward a more aggressive path. The beneficiaries are asymmetric. The clear winners are the AI supply chain — advanced packaging, memory, power infrastructure, and the contract manufacturers that sit between US designs and Chinese capacity — and the energy importers of Asia, which get a double benefit from cheaper oil and stronger regional demand. The exposed are the duration-sensitive growth names that have rallied without earnings to back them, and the oil producers whose margins were built on a war premium that is now being unwound.
The long-term read is structural in one direction only: the AI capacity race will not reverse, but the diplomacy trade will. That asymmetry should shape positioning more than any single session's move.
Three signals separate the scenarios. Upside: a Thursday US-China joint statement on AI crisis communications, plus core PCE at or below 0.2 percent month over month, would validate the synchronized-advance case. Base case: talks proceed without breakthrough, inflation prints hot-but-stable, and the market grinds higher on earnings with elevated volatility. Downside: the follow-up US-Iran meeting fails to produce a tangible opening, the strait remains restricted, and oil reclaims $100 — in which case the diplomacy discount reverses and the Fed's hiking path becomes the dominant narrative.
The rally is real, but it is being underwritten by two different clocks. The AI clock is measured in gigawatts and capex commitments, and it is ticking slowly upward. The diplomacy clock is measured in days between meetings, and it can stop at any moment. The Fed is watching both, and it is not done hiking. Until the central bank blinks, the burden of proof remains on the bulls.
