Why Ships Aren't Rushing Back to Hormuz Yet — Even After Ceasefire

HORMUZ PARADOX: CEASEFIRE, NO TRAFFIC

The two-week Iran-US ceasefire should be a pressure release. Instead, it's a confidence test the market is failing.

As of April 8, fewer than a handful of vessels have crossed the Strait of Hormuz since the July agreement. S&P Global tracked 244 tankers queued west of the strait and 156 east, but they're not moving. Kpler's risk analysts say there are "no clear signs yet of large-scale positioning or queuing that would indicate ships are preparing to move through in significant numbers."

Operators are holding back. Here's why three layers matter:

LAYER 1: THE INSURANCE TRAP War-risk premiums jumped over 1,000% during the crisis. Even with a ceasefire, insurers and P&I clubs aren't confident rates will collapse immediately. The risk hasn't disappeared—it's been deferred for 14 days. Shipowners know that if hostilities resume mid-voyage, their premium advantage disappears. The rational move is wait-and-see. Until underwriters signal durability, the passage economics don't work.

LAYER 2: UNCLEAR PASSAGE RULES Iran's framework for reopening the strait includes potential transit fees. Some intelligence suggests $1-2 million per tanker crossing. For a typical 1-2m barrel carrier, that's $0.50-$1.00 per barrel in additional shipping costs. Capital Economics estimates this could amount to a "de facto partial nationalisation of the shipping route." Operators need clarity on final terms. Ambiguity kills volume.

LAYER 3: THE REFINERY BOTTLENECK The International Air Transport Association warned that "it will take months for global jet fuel supplies to return to normal even after the Strait reopens because of disruptions to Middle East refineries." Key production nodes (Saudi, Qatar, UAE) sustained operational damage during the war. Reopening Hormuz doesn't fix downstream production. Tankers can flow, but there's no product to carry. That delays the recovery cycle and keeps operators cautious.

THE SO WHAT Markets priced in immediate relief. Oil dropped 15%+ on ceasefire news, touching $94/barrel. But that assumes rational economic behavior. Operators are not behaving rationally—they're behaving carefully. The shadow queue of 400+ tankers won't clear at $94. It will clear when confidence—not hope—returns. That's weeks, not days.

Until then, Hormuz remains effectively constrained. War-risk economics override peace logistics. The ceasefire is real. The confidence is not.
