Oil Prices Plunge Nearly 8% on U.S.-Iran Diplomacy Hopes as ISM Manufacturing PMI Jumps to 55.5
Oil prices fell sharply on Monday, November 2, 2026, with U.S. crude futures down nearly 8% in early-afternoon trading, as investors bet that the United States and Iran are moving toward a diplomatic resolution of the conflict in the Middle East. The energy slide arrived alongside a stronger-than-expected October reading from the Institute for Supply Management (ISM), which showed U.S. factory activity expanding for a 10th straight month. Together, the two developments helped the Dow Jones Industrial Average climb about 1% after October’s bruising tech sell-off.

Why Oil Prices Are Falling Today
Crude’s drop reflects shifting expectations around the U.S.-Iran conflict. According to The Motley Fool’s midday market report, crude prices plunged more than 7% “as investors bet on a diplomatic resolution to the conflict with Iran.” Yahoo Finance similarly attributed the move to reports that Washington and Tehran are seeking a diplomatic path to ending the war.
Developing information: No diplomatic agreement had been announced as of this writing. Reports from the region remain mixed — Iranian negotiators were reported to have left talks with Qatari mediators in Doha, and shipping risks in the Strait of Hormuz remain in the news, according to a Just Security news roundup citing Reuters. Traders are pricing in the possibility of de-escalation rather than a confirmed outcome.
What Lower Oil Prices Mean for Sectors
- Energy producers: ExxonMobil (NYSE: XOM) fell about 2.2% as crude tumbled, per The Motley Fool.
- Consumer cyclicals: The sector led gains at midday, as lower fuel costs ease pressure on household budgets and transportation-heavy businesses. Amazon (NASDAQ: AMZN) rose more than 4%.
- Laggards: Real estate and technology were the weaker groups at midday. Oracle (NYSE: ORCL) fell more than 6% after announcing plans to raise about $20 billion — roughly $10 billion in stock and $10 billion in bonds — to fund AI infrastructure.
ISM Manufacturing PMI: October 2026 by the Numbers
The ISM report, released at 10:00 a.m. ET, showed manufacturing activity accelerating. A PMI reading above 50% signals expansion. Production climbed to its highest level since November 2021, according to Yahoo Finance, and 12 industries reported growth.

The Inflation Signal Inside the Report
The Prices index eased 2.7 points to 75.2 but remains at a level indicating rapidly rising input costs. Yahoo Finance noted that prices “remained elevated” amid higher energy prices, tariffs and supply-chain bottlenecks. A sustained decline in crude could eventually relieve some of that pressure, but today’s oil move is a single-session change. The separate S&P Global U.S. Manufacturing PMI came in at 54.9 for October, down from 55.9 in September.
Interest Rates and the Fed
The 10-year Treasury yield edged lower, trading between roughly 4.88% and 4.94% during the session depending on the time of the quote (Yahoo Finance; The Motley Fool). The federal funds target range stands at 3.75%–4.00%.
Market pricing, not a forecast: Yahoo Finance reported that CME FedWatch data showed about 76% odds of a 25-basis-point rate hike at the Federal Reserve’s December meeting. Expert commentary: Apollo chief economist Torsten Sløk wrote in a Monday blog post that, by his model, rates would need to rise about 275 basis points, to 6.75%, by the end of 2027. These are market-implied probabilities and one economist’s view, not Fed guidance.
Context: Rebound After October’s AI Sell-Off
Monday’s gains follow a rough October. The Nasdaq Composite lost 5.2% for the month amid an AI-driven sell-off, and the Nasdaq 100 ended Friday about 9% below its October 6 record, according to Yahoo Finance.
