Six days ago, the Federal Reserve did something it hadn’t done since the summer of 2023: it raised interest rates. The Dow dropped more than 600 points that afternoon. Traders braced for the worst. And then, on Monday, the Nasdaq Composite closed at an all-time high.
It’s the kind of market whiplash that makes sense only when you remember one thing: this isn’t the economy of 2023. The AI boom is real, corporate earnings are holding up, and for all the hand-wringing about inflation, the underlying growth story is still intact. The question now is whether the narrow foundation of this rally can support the weight of what’s coming next.
The Fed Moves, Then Markets Move Faster
On September 16, the Federal Open Market Committee voted 12-0 to raise the federal funds rate by a quarter point to a target range of 3.75%–4.00% (CNBC). Chairman Kevin Warsh, in his first policy shift since taking the helm in May, called it the “right decision” — pointing to an economy that’s picked up speed, resilient consumer spending, and inflation that remains stubbornly above the 2% target.
The dot-plot projections revealed that 16 of 18 Fed officials expect at least one more quarter-point hike before year-end. The Fed’s own forecast now sees headline PCE inflation at 3.7% for 2026, with the 2% target not arriving until 2029 (Reuters). Translation: higher rates are sticking around.
President Trump responded on Truth Social, calling for rates to be slashed to “1%, or less,” arguing the U.S. economy is “BOOMING with new Investment!” The reaction echoed the kind of barbs he once directed at former Fed Chair Jerome Powell — though notably, he didn’t mention Warsh by name.
Nasdaq Hits a Record — but Look Under the Hood
Monday’s session was a barnburner for tech. The Nasdaq jumped 2.26% to close at 27,122.09 — a new record, its first since June. The S&P 500 gained 1.49% to 7,764.70. The Dow added 366 points, or 0.71%, to 52,048.83 (CNBC).
Three AI names did the heavy lifting:
- Intel jumped 12% on renewed AI chip enthusiasm
- AMD surged 10%, crossing the $1 trillion market cap threshold for the first time
- Qualcomm gained more than 9% as AI-driven demand showed no signs of cooling
But the breadth was concerning. A CNBC analysis noted that Monday’s rally displayed a pattern not seen since 1999 — a handful of mega-cap names carrying the entire index while the broader market treads water. When the rally is that skinny, it doesn’t take much to reverse it.
Oil Retreats, and So Do Yields — For Now
Helping stocks along was a sharp drop in crude. West Texas Intermediate fell 4.5% to $95.78 per barrel, while Brent slipped 3.4% to $100.34. The decline came despite Houthi attacks on Saudi Arabia over the weekend and a State Department warning urging Americans to reconsider travel to the Middle East (CNBC).
What’s keeping a lid on oil? Diplomacy. President Trump told Fox News he’d “probably” be open to meeting Iranian President Masoud Pezeshkian during this week’s UN General Assembly. The mere possibility of talks was enough to take the risk premium out of crude — at least temporarily.
Treasury yields followed oil lower. The 10-year shed 4 basis points to 4.951%, while the 30-year dipped to 5.284% — still elevated by historical standards, but off the 19-year highs reached on hike day.
The Week Ahead: Diplomacy and Data
Today, Richmond Fed President Thomas Barkin speaks at 1 p.m. ET — the first Fed voice since the hike. Later this week, the calendar heats up: September flash PMIs drop Wednesday, weekly jobless claims and new home sales arrive Thursday, and durable goods plus the final University of Michigan consumer sentiment reading land Friday.
Also looming: the Trump-Xi summit, where AI governance, tariffs, and critical minerals are on the agenda. Treasury Secretary Scott Bessent met with Chinese Vice Premier He Lifeng ahead of the talks — a signal both sides are at least attempting to keep economic channels open (CNBC).
Bottom Line
The market’s message this week is simple: the Fed can hike, oil can spike, and geopolitical risk can flare — but as long as AI earnings keep delivering and diplomacy keeps crude from spiraling, there’s a bid under stocks. The question is durability. A rally built on three chipmakers and a rumor of peace talks isn’t a broad recovery. It’s a bet. And in a week packed with data and diplomacy, that bet is about to get tested.
