Iran's assault on a UAE oil port and US warships in the Strait of Hormuz tests a shaky cease-fire, reigniting fears of regional instability. The attacks, involving cruise missiles and projectiles, followed US efforts to escort commercial vessels through the strategic waterway. Two US-flagged ships transited safely, but tensions persist as oil prices surged 3% on fears of supply disruptions. US Central Command confirmed Iran's strikes, while President Trump warned against further aggression near the strait.

The escalation risks destabilizing global oil markets, with Brent crude futures hitting a two-year high. Analysts warn that prolonged hostilities could disrupt 20% of the world's oil supply, impacting energy-dependent economies. The fragile truce, brokered earlier this year, now faces renewed pressure as Iran's actions challenge diplomatic efforts to de-escalate.

Trump's blunt warning underscores US resolve to protect maritime routes, though military options remain limited. The Strait of Hormuz, a critical chokepoint for 17 million barrels of daily oil shipments, remains a focal point. Meanwhile, Gulf nations brace for potential fallout, with UAE officials condemning the attacks as a violation of sovereignty.

This flare-up highlights the fragility of geopolitical balances in the region. With sanctions relief and nuclear talks stalled, the conflict could spill over into broader economic repercussions, from shipping insurance costs to energy sector investments. Markets await clarity on Iran's objectives and the US response threshold.
