Stock Futures Decline as US-Iran Conflict Intensifies Over Hormuz Strait

Key Takeaways

• Major US equity futures declined Monday following a weekend spike in US-Iran hostilities that jeopardized diplomatic efforts
• Dow futures retreated 0.6%, while S&P 500 and Nasdaq 100 futures declined 0.5%
• US forces intercepted an Iranian vessel; Iran responded with attacks on shipping and a Strait of Hormuz closure
• Crude oil jumped dramatically, with WTI climbing 5.7% to approximately $87/barrel and Brent advancing 4.7% to roughly $95/barrel
• Gold declined 1.3%, the greenback ticked up 0.1%, and Bitcoin decreased 0.5% to $74,942

American equity futures pointed toward a negative open Monday morning following a weekend escalation of hostilities between Washington and Tehran that dampened optimism for diplomatic resolution and triggered a significant spike in crude oil valuations.

Dow Jones Industrial Average futures declined 394 points, representing a 0.6% decrease. Both S&P 500 and Nasdaq 100 futures registered approximately 0.5% losses.

The downturn follows an impressive stretch for American equities. Both the S&P 500 and Nasdaq established fresh all-time highs during the previous week. The Nasdaq had remarkably achieved 13 straight sessions of gains — marking its most extended winning run since the early 1990s.

This positive trajectory now confronts significant headwinds.

During the weekend, President Trump announced that US Naval forces had intercepted an Iranian commercial vessel attempting to circumvent the blockade at the Strait of Hormuz, disabling its propulsion system. Tehran retaliated by launching attacks on maritime traffic in the strategic waterway and implementing a complete shutdown of passage, reversing prior commitments to permit limited vessel transit.

Crude Surges, Flight-to-Safety Assets Show Mixed Signals

Oil markets responded immediately. Brent crude surged 4.8% to approximately $94.70 per barrel. WTI advanced 5.1% to $86.82. While both benchmarks continue trading beneath the psychologically significant $100 threshold that would amplify inflation concerns, the upward trajectory is creating unease among market participants.

The intensified disruption at the Strait of Hormuz — a critical passage handling approximately one-fifth of worldwide petroleum shipments — is rekindling inflation anxieties precisely as financial markets had begun anticipating a more predictable economic environment.

The US dollar strengthened modestly by 0.1% versus major currency pairs. Gold, traditionally viewed as a safe-haven asset, surprisingly retreated 1.3% to $4,818 per ounce. Bitcoin decreased 0.5% during the 24-hour period to $74,942. The benchmark 10-year Treasury yield advanced 3 basis points to 4.27%.

Looking Forward: This Week’s Calendar

Corporate earnings releases maintain their rapid pace. Tesla (TSLA), Intel (INTC), and United Airlines ($UAL) are scheduled to publish quarterly results this week, offering investors opportunities to shift attention back to company performance metrics instead of international conflicts.

As of Monday’s pre-market session, Dow futures traded at 49,365, S&P 500 futures stood at 7,129.50, and Nasdaq 100 futures registered 26,718.75.

Iran’s Islamic Republic News Agency maintained its pessimistic stance regarding negotiation prospects through Sunday.
