More Oil, Same War: Why Increased Exports Aren’t a Sign of Iran’s Collapse

Council on Foreign Relations | Max Boot

President Donald Trump’s eight-month-old war with Iran has entered a new phase as non-Iranian Middle East oil exports rebounded in September to just under 70 percent of prewar levels despite an ongoing maritime conflict. Although the U.S. Navy blockaded Iranian exports in July, Brent crude remains above $100 a barrel, driving domestic gas prices to $4.47 a gallon.

This persistent price pressure stems from the high cost of alternative shipping bypasses and extensive damage to regional energy infrastructure. The Strait of Hormuz remains highly treacherous. While the Islamic Republic suffers from an inflation rate averaging over 80 percent, its leadership refuses to capitulate, instead escalating attacks on shipping and utilizing Houthi allies to threaten the Bab al-Mandab Strait. In response, Washington is preparing to deploy a third aircraft carrier and ten thousand additional troops, yet a lasting resolution will ultimately require returning to negotiated concessions.

Comment

The reliance on alternative maritime bypasses to mitigate the Strait of Hormuz blockade exposes the severe logistical friction of long-distance energy rerouting. Diverting crude through the Red Sea and the Suez Canal has driven shipping costs to China up to $35 a barrel, demonstrating that volume recovery does not equate to economic efficiency. This logistical strain is compounded by the vulnerability of these bypasses, as seen in the Houthi control of the Bab al-Mandab Strait. The geographical shift in transit routes merely redistributes the operational risk to alternative choke points like the Bab al-Mandab Strait.

The sustainment of this maritime security architecture depends on an intensive U.S. Navy escort presence that strains Fifth Fleet rotation schedules. Deploying three carrier strike groups simultaneously to the Middle East forces the Pentagon to draw naval assets away from the Indo-Pacific theatre. This prolonged escort mandate depletes the operational readiness of Arleigh Burke-class destroyers, as continuous deployment outpaces the maintenance capacity of U.S. naval shipyards.

Strategic Question for Discussion

If the Houthi blockade of the Bab al-Mandab Strait persists indefinitely, how long can the Pentagon sustain the deployment of Arleigh Burke-class destroyers before the resulting maintenance backlog severely degrades naval readiness in the Indo-Pacific?

The available evidence points toward a critical operational threshold within twelve to eighteen months, as prolonged deployments accelerate wear on propulsion and radar systems. My assessment is that the Pentagon will be forced to transition from continuous active escorts to a reactive, strike-based posture to prevent a systemic readiness collapse. This shift would inevitably increase the risk profile for commercial shipping transiting the Bab al-Mandab Strait, forcing a more permanent reliance on longer Cape of Good Hope bypasses.
