Hormuz Transit Collapses to Near-Zero; Iran Blockade Cuts Global Oil Flow 99%
Hormuz closure feeds back into the March 17 missile depletion signal: sustained air operations against Iran require energy-intensive logistics, but rising global oil prices from the blockade increase fuel costs for US military transport and operations, creating a cost spiral that accelerates the munitions replenishment crisis already flagged by Nikkei Asia.
Additionally, energy price shocks force allied defense budgets to choose between energy subsidies and procurement — this reshapes the timeline for allied rearmament that Gulf states were demanding.
A near-complete Hormuz closure forces immediate energy price spikes and exposes US allies' energy vulnerability.
Global oil supply loses ~20-25% of transit capacity; LNG and refined products face rerouting delays of 15-20 days around the Cape of Good Hope. This validates the March 16 signal in which Gulf Arab states privately urged the US to pursue regime-threatening objectives — they were already signaling energy supply as a constraint on their tolerance for limited strikes.
Defense primes reliant on energy-intensive production (aerospace, shipbuilding, semiconductor fabs) face margin compression from power costs. The blockade also signals Iranian capability to enforce a chokepoint despite ongoing strikes on its military infrastructure, which complicates US-Israeli damage assessments of their air campaign effectiveness.
The article does not specify current daily transit volumes (exact number, not just 'near zero'), does not confirm whether Iran is actively enforcing the blockade via naval/missile interdiction or relying on shipping industry avoidance, and does not distinguish between tanker vs. dry cargo flow — cri...
