US gasoline prices have climbed above $4 per gallon for the first time in more than a month, driven by renewed military conflict between the United States and Iran that has disrupted oil flows through the Strait of Hormuz.

The surge in pump prices coincides with global crude benchmarks briefly touching $90 per barrel early Monday, reflecting acute supply fears amid the escalation.

The price spike underscores the persistent vulnerability of global energy markets to geopolitical shocks in the Persian Gulf.

While the initial reaction saw crude prices surge, both nations have since signaled a willingness to resume diplomatic talks, introducing a degree of uncertainty into the near-term outlook for energy prices.

This development follows a period of heightened shipping risk and diplomatic opacity in the region, which has already weighed on trade route security and investor sentiment.

The recent escalation marks a significant intensification of the conflict, moving beyond diplomatic posturing to direct military engagement that threatens critical infrastructure.
