Stock futures surged on Wednesday after the U.S. and Iran agreed to a two-week ceasefire, narrowly averting a major military escalation. The announcement led to a 15% drop in Brent crude oil prices, providing relief for energy-sensitive sectors like airlines. Delta Air Lines, which owns a refinery near Philadelphia, is expected to show relative resilience compared to peers due to this vertical integration.

Why it matters

The de-escalation between the U.S. and Iran offers a vital reprieve for global markets that had been bracing for a potential supply chain crisis and further oil price spikes. This immediate calm provides breathing room, but the long-term outlook remains uncertain as the two sides work to negotiate a more conclusive agreement.

The details

Just hours before a critical deadline, President Trump and Iranian officials agreed to a temporary cessation of hostilities and a coordinated reopening of the Strait of Hormuz. International crude prices cratered nearly 15% on the news, with Brent crude falling to approximately $93 per barrel as supply chain panic eased. While the long-term outlook remains uncertain, the immediate de-escalation provides a vital reprieve for global markets and energy-sensitive sectors.
