Markets Today September 2 2026: Iran War Drives Oil Past $95 as Fed Hike Odds Hit 66%

Markets today September 2 2026 are opening under significant pressure: Brent crude has crossed $95 a barrel, the Federal Reserve’s September 15 meeting is now priced as more likely than not to deliver a rate hike, and Bitcoin is pulling back from its best August ever. Meanwhile, Nvidia just delivered a $96.2 billion quarter that beat Wall Street by a wide margin. Here is the full breakdown of what is moving global finance this Wednesday.

Markets Today September 2 2026: The Overnight Snapshot

While US investors slept, three major developments shifted the market outlook for the week. Fresh US-Iran military escalation sent Brent crude above $95 a barrel. The IRGC threatened to block commercial shipping through the Strait of Hormuz, rattling Asian energy markets. And Treasury yields continued their climb: the 10-year hit 4.79% and the 30-year touched 5.27%, compressing valuations across growth and tech stocks.

Asian equities fell broadly. European markets opened in the red. US futures pointed lower ahead of the open, with the Invesco QQQ Trust (QQQ) down 0.59% in premarket. Inflation expectations over a one-year horizon have crept up to 2.5%, and investors are recalibrating their entire rate and risk model for the fall.

Oil Tops $95 as Iran War Escalates

Brent crude punched through $95 a barrel overnight as the US-Iran conflict entered a dangerous new phase. A US submarine reportedly sank an Iranian warship, triggering immediate IRGC threats to block the Strait of Hormuz — the chokepoint through which 20% of global oil flows each day. WTI crude gained more than 3% in early Asian trading, and traders are now pricing in the possibility of Brent reaching $109 or higher if shipping through the Gulf is fully disrupted.

President Trump offered naval escorts for commercial vessels transiting the Persian Gulf, and Treasury Secretary Scott Bessent outlined additional stabilization measures for Gulf energy markets. But traders are not convinced the risk is contained. This supply shock is arriving at the worst possible time: US consumer prices are up 3.4% year over year, and the Fed’s preferred PCE measure sits at 3.7%. A sustained oil surge feeds directly into headline and core inflation — exactly the signal the Fed is watching ahead of September 15.

Energy stocks are the lone standout in an otherwise weak tape. Major oil producers and refiners are outperforming as the crude price surge flows directly to margins. For the broader market, this is a stagflationary warning: rising input costs at a time when rate-sensitive sectors are already under pressure from climbing yields.

S&P 500 and Nasdaq Under Pressure as Bond Yields Climb

The S&P 500 fell 0.7% and the Nasdaq Composite dropped 1.3% on Tuesday, and US equity futures are pointing lower again on Wednesday. The 10-year Treasury yield at 4.79% and the 30-year at 5.27% are functioning as a ceiling on equity multiples, particularly for tech and growth stocks valued on long-duration cash flows. The QQQ was down 0.59% in premarket.

One-year ahead inflation expectations have climbed from under 2% in recent weeks to 2.5%, a move that directly affects how bond markets price Fed policy. Rising real yields are attracting capital away from equities and into fixed income, adding another layer of pressure on already-stretched tech valuations. Defensive sectors — utilities, consumer staples, energy — are outperforming on a relative basis, while semiconductors and software are lagging.

Fed Rate Hike September 15: Odds Now at 66%

Before Jackson Hole, markets priced a 70% probability that the Fed would hold rates steady at the September 15 meeting. That has now completely reversed. Fed Chair Kevin Warsh used his keynote at the annual Jackson Hole symposium to signal he was “committed to fighting inflation,” and futures markets responded by pricing a 66% probability of a 25-basis-point hike per CME FedWatch. Prediction markets on Kalshi put the odds at 48%, but the direction of travel is clearly toward a hike.

Two forces have lowered the bar for the Fed to act. First, the ongoing Iran conflict is keeping energy prices elevated, making it harder for headline inflation to fall toward the 2% target. Second, the Fed’s decision to hold rates in July — when many expected a hike — eroded confidence in the institution’s willingness to act preemptively. Warsh’s Jackson Hole remarks appear designed to restore that credibility before the September decision.

The September 15 decision will be the most closely watched Fed meeting of 2026. A hike would mark a resumption of the tightening cycle after July’s pause. A hold would be seen as dovish capitulation in the face of energy-driven inflation, potentially damaging the Fed’s credibility further. Either way, the next two weeks are the most important for markets this year.

Nvidia Crushes Earnings: Revenue of $96.2 Billion and Stock Up 8.7%

Nvidia reported $96.2 billion in Q2 FY27 revenue on August 26, up 106% year over year and well above the $92.2 billion consensus estimate. Earnings per share came in at $2.22 against a $2.09 estimate. Gross margins expanded to 75.0%, up from 72.7% a year ago. The stock jumped 8.7% the following session — its best single-day gain since April 2025. With Nvidia controlling an estimated 80 to 90% of the AI accelerator market, the result confirmed that enterprise and hyperscaler AI spending is still accelerating at a remarkable pace.

The results matter well beyond Nvidia itself. The company’s earnings are a real-time indicator of how much capital Microsoft, Alphabet, Amazon, and Meta are directing toward AI infrastructure. A $96 billion revenue quarter means those capex budgets are not just holding but growing. The broader AI trade remains cautious given rising rates and geopolitical risk, but Nvidia has now delivered four consecutive quarters of triple-digit revenue growth.

Bitcoin Slides to $78K as September Opens Soft

Bitcoin opened September at around $78,500, sliding toward $77,900 as risk-off sentiment and rising rate expectations weighed on crypto assets. August was Bitcoin’s best month of the year — prices rose 25% — driven by optimism around the Trump administration’s CLARITY Act and record inflows into spot Bitcoin ETFs. That momentum has not carried into September.

The macro setup entering September is less friendly: a 66% probability of a Fed hike on September 15, oil-driven inflation, and rising real yields all weigh on risk assets including crypto. Fundstrat’s Tom Lee maintains his $150,000 price target, arguing that a hike-and-done scenario would ultimately be bullish for hard assets like Bitcoin. For now, $77K is the key support level — a sustained break below it could accelerate selling going into the Fed meeting.
