NEW YORK, April 20, 2026, 09:36 EDT
- Dow, S&P 500, and Nasdaq 100 futures slipped roughly 0.4% early Monday; Brent crude edged closer to the $95 mark per barrel.
- After the U.S. seized an Iranian cargo vessel, Tehran signaled it would skip new negotiations for the time being—knocking back optimism that last week’s ceasefire would stick.
- Investors brace for a packed earnings week as shipping traffic in the Strait of Hormuz slows to a crawl and inflation worries resurface.
Stock futures in the U.S. slipped Monday, while oil prices surged after Washington seized an Iranian cargo ship, and Tehran responded by ruling out fresh talks with the U.S. Contracts for the Dow, S&P 500, and Nasdaq 100 dropped 0.45%, 0.41%, and 0.39% respectively. Brent crude, on the other hand, climbed roughly 5%.
This shift lands just after Wall Street wrapped up last week at fresh highs. The S&P 500 and Nasdaq each notched new closing records for a third consecutive day on Friday, after Iran’s brief statement that the Strait of Hormuz remained open. That news helped fuel a rally strong enough to wipe away the market’s earlier war-driven losses.
Hormuz isn’t your average corridor. Roughly a fifth of global oil and liquefied gas moves through here, but on Monday, traffic sank to only three crossings over 12 hours—down from Saturday’s more than 20. The sharp drop has rattled investors, putting fuel prices, inflation, and rate hike fears back on the table as earnings reports pick up speed.
Aberdeen’s Lizzy Galbraith described the latest developments as “diplomatic whiplash,” warning the path to a lasting ceasefire remains choppy—“two steps forward, one step back.” This week, investors are eyeing results from Lockheed Martin, RTX, IBM, ServiceNow and Tesla. LSEG figures project S&P 500 earnings will climb 14.4% in the first quarter. Reuters

Sector moves stuck to the usual script. Exxon Mobil and Chevron were each up roughly 1% in premarket action; Occidental Petroleum did a bit better, gaining 1.7%. On the flip side, pricier crude weighed on airlines—American Airlines and Delta Air Lines both dropped 2.6%, with United Airlines down 3.2%.
Fallout didn’t stay local. The STOXX 600 in Europe slid 1.1%. Airlines—easyJet, Lufthansa, Ryanair—were hit hardest, losing between 3.1% and 4%. Over in Asia, indexes closed up in Tokyo, Seoul, and Hong Kong, but those gains cooled from the highs earlier in the session.
Oil analysts are pointing to deeper trouble in the physical market than recent price moves suggest. According to June Goh at Sparta Commodities, crude production of 10 million to 11 million barrels a day is still offline. Bjarne Schieldrop from SEB highlighted ongoing pressures: rerouted shipments, extended travel times, and pricier freight and insurance are keeping supply tight.
The outlook remains up in the air. After an initial climb, the dollar surrendered some of its advance. Chris Weston at Pepperstone called the move “orderly,” not the mark of a full-blown volatility jolt—implying traders may still be betting on renewed negotiations. Should that assumption unravel and Hormuz remain closed, pricier oil stands to squeeze consumers, cut into corporate profits, and dampen rate-cut expectations even further. Reuters
Wall Street finds itself caught in a tough spot. The war—which started Feb. 28 and has dragged into its eighth week—has sent stocks on a wild ride, swinging on every diplomatic signal. By April 15, the S&P 500 had clawed back all its earlier losses, even notching a new high. But Monday’s drop is a different test: Can earnings hold the rally together if Gulf shipping stays clogged and the ceasefire slips apart?
