Brent crude surged 9.0% to $100.29 a barrel and West Texas Intermediate rose 8.9% to $94.97 as Iranian attacks on shipping lanes threaten the Strait of Hormuz.

Geopolitical instability in the region has overshadowed short-term supply assurances, with traders prioritizing conflict-driven risks over inventory replenishment efforts. The IEA's intervention, while substantial, failed to calm market nerves as fears of sustained output interruptions persist.

This sharp price movement underscores the fragility of energy markets amid escalating tensions, highlighting how geopolitical flashpoints continue to dominate commodity trading dynamics.
