Ceasefire Frays as Iran Claims Deal Breached
US stock futures fall 0.4% as Tehran says Israeli strikes violated the two-week truce. Oil rebounds 3% with the Strait of Hormuz still effectively closed.
The ceasefire lasted less than 24 hours before cracks appeared.
Iran halted tanker traffic through the Strait of Hormuz Thursday morning, claiming Israeli strikes on Lebanon violated the terms of Tuesday's US-Iran agreement. President Trump responded with a warning that troops would remain in the region and the "shootin' starts—bigger and stronger than anyone has ever seen" if Tehran doesn't comply.
Futures retreated on the news. The Dow dropped 0.4%, roughly 180 points, to 47,963. S&P 500 futures fell 0.4% to 6,806. Nasdaq 100 futures slipped 0.3%.
The Wednesday Rally Now Looks Fragile
This reversal comes after the market's strongest session in a year. The Dow gained 1,325 points Wednesday—its best day since April 2025—on news of the two-week truce. The S&P 500 jumped 2.51% and the Nasdaq surged 2.80%.
That optimism is fading fast.
| Index | Wednesday Close | Thursday Futures |
|---|---|---|
| Dow | +2.85% (+1,325 pts) | -0.4% |
| S&P 500 | +2.51% | -0.4% |
| Nasdaq 100 | +2.80% | -0.3% |
The core problem: both sides are accusing each other of breaching the agreement. Iran says continued Israeli operations—which the US hasn't explicitly addressed—violate the spirit of the deal. Washington says Iran is failing to reopen the Strait to commercial shipping as promised.
Oil Bounces Back
Crude reversed some of Wednesday's 16% collapse. Brent jumped roughly 3% back toward $98 per barrel. West Texas Intermediate rose similarly.
The Strait of Hormuz carries about one-fifth of global crude and liquefied natural gas flows. It remains largely blocked despite the ceasefire announcement. Until tankers actually start moving again, supply disruption pricing stays in the market.
Traders who bought the relief rally Wednesday are now hedging or taking profits. The overnight Asia session saw modest gains—the Nikkei held onto most of its 5.4% Wednesday surge—but European futures opened flat to lower.
What This Means
The ceasefire isn't dead, but it's on life support. Negotiations are supposed to continue, with both sides still technically committed to the two-week framework. The question is whether the agreement survives contact with reality.
For markets, the implication is continued volatility. Wednesday's rally reflected the best-case scenario—a deal, reopened shipping lanes, oil back to pre-war levels. Thursday's pullback reflects the more likely path: messy negotiations, partial compliance, and oil staying elevated.
The Fed situation gets more complicated. We covered Hammack's rate hike comments Wednesday—inflation could hit 3.5% in April. If oil stays above $95, that forecast becomes more likely. Rate cuts are off the table regardless; the question is whether the Fed has to consider tightening.
Airlines that surged on the oil drop—Delta, American, Southwest—are giving back some gains in premarket trading. Energy stocks are rebounding. The sector rotation that unwound Wednesday is partially reversing.
The two-week ceasefire window expires around April 22. That gives markets roughly two weeks of headline risk and whipsaw moves. Plan accordingly.
