US Forces Begin Hormuz Clearance Operations; Oil Prices Spike as Strait Reopening Enters Active Phase

U.S. warplanes and helicopters initiated operations to reopen the Strait of Hormuz on March 20, 2026, according to the Wall Street Journal. The operation follows Iran's near-total blockade of the strait over the preceding 72 hours, which cut global oil transit by approximately 99%. Oil prices have risen sharply in response to the closure and ongoing conflict.

Sustained Hormuz clearance operations lock U.S. naval aviation into a permanent escort mission, consuming carrier air wing sorties that would otherwise support operations in the Indo-Pacific.

Simultaneously, the blockade itself—not yet fully broken—keeps global oil prices elevated, raising operating costs for allied navies conducting concurrent freedom-of-navigation operations and increasing pressure on allied governments to fund parallel energy security initiatives (LNG spot purchases, strategic reserves drawdown).

If Iran maintains even partial denial capability, the U.S. faces a choice between accepting higher transit risk (reducing insurance and shipper confidence) or extending the air campaign deeper into Iranian territory, expanding the conflict's geographic footprint.

WHY IT MATTERS

This marks the transition from air-to-air/air-to-ground strikes to active sea-control operations.

The U.S. is now committing aviation assets to physically contest Iranian control of the strait—a higher-cost, sustained operation than previous strikes. Success depends on whether U.S. forces can suppress Iranian anti-ship capabilities (Hormuz-adjacent missile batteries struck on March 18, but Iranian naval assets remain operational).

If the clearance operation stalls or suffers attrition, oil prices will remain elevated indefinitely, creating pressure on allied economies and potentially forcing early ceasefire negotiations. If successful, it unlocks LNG and crude exports but validates the U.S. commitment to open-ended operations—consistent with Hegseth's March 19 statement that the conflict has no defined end date.

WHAT THIS DOESN’T TELL US

The article does not specify which Iranian anti-ship systems remain operational, the scale of U.S. aviation commitment (number of sorties, aircraft types, or rotation schedule), or whether multinational escort operations announced by seven nations on March 19 are coordinating with U.S. clearance eff...
