This is the first War & Markets weekly briefing — our regular look at the war impact on markets, from crude oil and natural gas to defense stocks, gold, equities, and wheat. Every figure below was checked on Friday, October 2, 2026, at 7:00 PM Central Time; markets move constantly, so treat these as snapshots, not live prices. Each move is paired with the conflict news reported as driving it, attributed to the outlet that reported it.
The dominant story this week was the seven-month-old US-Iran war: Washington is sending a third aircraft-carrier strike group and up to 10,000 additional troops to the Middle East as President Trump weighs resuming strikes on Iran after the US midterm elections, while Tehran rejected the latest ceasefire terms and the Strait of Hormuz remains only partially reopened.
Oil: a tug-of-war around $100
Brent crude spent the week swinging around the $100-a-barrel mark and ended Friday near $99.56, down about 2.7% on the session; US benchmark WTI fell roughly 4% to about $89.22, according to Barron's end-of-week coverage. The choppiness tells the story of two opposing forces.
Pushing prices up: on Thursday, crude surged more than 2% after the Wall Street Journal reported the third US carrier deployment and Trump's post-midterm strike planning, while Reuters reported that Chinese refiners had suspended refined-product exports for October to preserve domestic inventories. Barchart noted the gains accelerated on deadlocked US-Iran talks keeping the Strait of Hormuz from fully reopening, plus Russia extending its diesel export ban through October.
Pulling prices down: on Friday, the G7 agreed to release 100 million barrels of crude oil and diesel from emergency stockpiles, and JPMorgan estimated Middle East crude exports had rebounded to 17.5 million barrels per day — about 98% of pre-war levels. Bloomberg tracking showed Saudi crude exports at 5.28 million bpd in September, the highest in seven months, after the kingdom restored part of its East-West Pipeline capacity damaged by earlier drone strikes. JPMorgan added a caveat that matters: refined-product flows were still only about 58% of pre-war levels, which is why diesel markets stayed tight even as crude eased.
Defense stocks slip as escalation builds
In a week thick with escalation headlines, America's big defense contractors mostly drifted lower. Lockheed Martin closed Friday at $505.41, essentially flat on the day; RTX ended at $184.68, down about 0.2%; and Northrop Grumman fell 0.8% to $478.00 — a new 52-week low, with the stock down roughly 11% over the past month, according to market data and the Daily Political's Friday report.
That divergence is worth noting without over-reading it: rising geopolitical tension does not automatically lift defense shares, which also answer to contract timing, margins, and analyst sentiment. On the fundamental side, RTX raised its full-year 2026 sales outlook to $95–96 billion in late September, and Lockheed Martin won a US Army contract worth up to $1.2 billion for its Precision Strike Missile in September — reminders that the order books behind these stocks move on procurement cycles as much as headlines.
Gold and gas: the hedges
Gold, the classic haven bid, rose about 0.7% on Friday to roughly $4,184 an ounce — though it remains down about 3.4% on the week and roughly 11% year-to-date, well below its January all-time high near $5,318. The metal's muted response to a week of carrier headlines suggests traders are, for now, more focused on interest-rate signals than on war risk.
US natural gas was firmer: the Henry Hub benchmark traded around $3.01–3.12 per MMBtu, up about 2% on the day, with November futures settling at their highest since late September on bets that the Cove Point LNG export plant is close to restarting, per Finimize. In Europe, the TTF benchmark sat at $83.76 per MWh, up about 1% — a reminder that European heating and power costs remain tightly coupled to Gulf shipping risk heading into winter.
Stocks and wheat: the wider picture
The S&P 500 closed Friday at 7,722.72, up 0.7%, as a weaker-than-expected jobs report cooled bets on further interest-rate hikes; AI-linked stocks led, with Micron's strong earnings lifting the tech trade, according to the Wall Street Journal and Investopedia. Notably, MarketWatch documented how the seven-month Iran war has flipped the oil–stocks relationship: the 63-day correlation between WTI and the S&P 500 fell from near zero before the war to around minus 0.48 — when oil jumps, stocks increasingly fall.
In food commodities, CBOT December wheat closed Thursday at $6.82¾ a bushel, up 7 cents, in what Barchart described as modest strength on short-covering. The war link runs through the Black Sea: Ukraine's agriculture minister warned this week that the country's wheat area could drop 17% for 2027 as backed-up supplies squeeze farmers, keeping a slow-burn risk under a market that is otherwise well supplied.
