Last week gave you the hike. Today the market told you what it thinks about the hike. Oil fell 4%, the Nasdaq set a new all-time closing high, and the 10-year yield slipped back below 5%. Three numbers, one message: the inflation scare peaked on Wednesday.
The Close
Strong start to the week. Oil broke below $93, chip stocks ripped, and every major index closed green. The Nasdaq hit a fresh all-time closing high — its first since June 2 — on the back of a monster rally in semiconductors and AI names.

The S&P gained 1.5%. The Dow added 388 points. The Nasdaq surged 2.26% to 27,122, blowing past its previous record close of 27,094. Ten of 11 S&P sectors finished higher. The only one in the red was energy, down 1.9%, because when oil falls 4% the stocks that pump it fall with it.
Intel was the headliner. Up 11% after announcing a partnership with Taiwanese display maker AUO to develop next-generation chip packaging — and with reports that SK Hynix is exploring a deal with the company. But the move was bigger than one deal. It was the whole AI trade snapping back to life ahead of the Trump-Xi summit on Thursday. AMD gained 8% and crossed $1 trillion in market cap for the first time. Qualcomm added 8%. Meta surged 12% after its new AI agent MUSE sparked a rally among server CPU suppliers.
Novo Nordisk was the biggest loser among large caps. Down 8% after its long-term obesity strategy left investors cold. The weight-loss drug market is getting crowded, and the Street wanted more than a slide deck. HP fell 4.2% after warning that global PC volumes will shrink in 2027. Warner Bros. Discovery jumped 9.8% on reports that the Paramount merger is getting closer to clearing its state AG hurdles.
The most dramatic single-stock move was Grail, up 35.5% ahead of an FDA review for its multi-cancer blood test. That's a biotech event trade, not a macro signal — but when a $2 billion company moves a third in one session, it gets your attention.
What The Market Is Pricing In
Oil fell 4% and the Nasdaq hit an all-time high on the same afternoon. That combination tells you everything about where the market thinks the next six months are headed.
Start with oil. WTI settled at $92.02, down from $96.08 the day before. Saudi Arabia said it expects to restore about half of its East-West pipeline capacity within days. Crude exports from the Gulf have surged past 4 million barrels a day this month, up from a 13-year low of 2.4 million in August. JPMorgan estimated that total oil flows out of the Gulf averaged 17.1 million barrels per day over the last 10 days. The worst of the supply crunch is easing.
And there's a diplomatic opening. Iran's President Pezeshkian will lead a delegation to the UN General Assembly in New York tomorrow. Trump said over the weekend that the choices are a deal, economic rot, or something worse — but he left the door open. That's enough for crude traders to start pulling some of the war premium out of the barrel.
Now follow the chain. When oil falls, it takes the heat off inflation. When inflation cools, bond investors stop demanding as much return to lend the government money. The 10-year yield slipped back below 5% today, settling around 4.96%. A week ago it topped 5.04% for the first time since 2007. The move is modest — a few basis points — but the direction matters more than the size. When the 10-year stops going up, stocks breathe.
And when bonds stop punishing everything else, money moves back into risk. This is what they call a relief rally on Wall Street — the thing that was scaring the market starts going away, and the bid comes back.
The market is betting the Fed hiked once and won't need to hike again. At Wednesday's meeting, the Fed penciled in one more increase this year. But on Friday, futures were pricing roughly 42% odds of two or more hikes by year-end. Today, with oil breaking below $93 and the Saudi pipeline coming back, those odds are fading. The whole rate path for the rest of 2026 is getting rewritten.
The Trump-Xi summit on Thursday adds another layer. Treasury Secretary Bessent met with Chinese Vice Premier He Lifeng over the weekend and called the talks "very successful." He proposed a new U.S.-China AI dialogue with national security guardrails. If the summit produces a tariff truce extension — or even just a framework for AI cooperation — that's one more reason for the market to price in a better second half.
Here's the forward read. If oil stays below $95 and the summit goes well, the market will start pricing rate cuts by mid-2027. That's a big swing from seven days ago, when $105 oil and a 5% yield made it feel like 2007 all over again. The direction changed. The question now is whether it sticks.
I've seen this pattern before. In March 2023, Silicon Valley Bank collapsed in the middle of a Fed hiking cycle. The crisis changed the math overnight. The Fed paused, and stocks ran. Oil breaking below $93 is a different kind of shock, but it changes the inflation math the same way — remove the biggest input, and the pressure to tighten evaporates.
What's Next
Three things I'm watching this week:
01 — S&P Global Flash PMIs (Wednesday, September 23, 9:45 AM ET)
This is the first post-hike business confidence reading. The PMIs measure how companies feel about new orders, hiring, and prices. If the manufacturing PMI stays above 50 — the line that separates expansion from contraction — it tells you the economy can absorb a rate hike without rolling over. If it dips below 50, the one-and-done thesis gets harder to believe, because the Fed just tightened into a slowdown.
02 — The Trump-Xi Summit (Thursday, September 24)
The biggest geopolitical event on the calendar. Trump and Xi meet in Washington with tariffs, critical minerals, and AI on the table. Several major tech CEOs — Nvidia's Jensen Huang, OpenAI's Sam Altman, Qualcomm's Cristiano Amon, Microsoft's Satya Nadella — will attend a dinner with the Chinese president. If the tariff truce gets extended or there's a formal AI cooperation framework, that's fuel for another leg higher in tech. If talks stall, the chip rally loses its catalyst.
03 — Michigan Consumer Sentiment Final (Friday, September 25, 10:00 AM ET)
The preliminary reading came in at 47.8 — the second-lowest reading in the survey's history. Year-ahead inflation expectations jumped to 4.6%, the highest since June. That's consumers telling you they feel the oil shock in their gas bills and their grocery carts. The final number on Friday will tell you whether the mood got worse in the back half of September, or whether falling oil prices over the last few days started to take the edge off.
If oil holds below $95 and the PMIs don't crack, the one-and-done story holds. If they don't, last week's pain was just the warm-up.
That's it for today. See you tomorrow after the close.
