Five tankers seen loading oil on Iran's Kharg Island, Bandar Mahshahr port

The market is likely underestimating how much of this is a storage-and-process problem rather than a pure export shutoff. If Iranian terminals keep drawing crude into floating storage to preserve reservoir/infrastructure integrity, the first-order effect is less immediate lost supply than a delayed, more disorderly release pattern: outages may be postponed for days, then converted into a sharper forced curtailment if tanker capacity is trapped or inspections intensify. That creates a convex risk profile for prompt crude and refined product cracks, with the biggest move coming if traders conclude the system has shifted from temporary congestion to involuntary shut-ins.

The second-order winners are not just upstream producers but the entire non-Iranian maritime security complex. Higher freight, rerouting, and convoy requirements should benefit ship insurers, naval contractors, and tanker operators with cleaner compliance exposure, while penalizing owners with Middle East exposure and weaker charter flexibility. The more important cross-asset implication is that this raises the probability of a short-lived but violent dislocation in diesel and LPG logistics, which can ripple into industrial freight margins and emerging-market import bills even if Brent only grinds higher modestly.

The key contrarian point is that a headline reopening does not necessarily normalize risk premia. If vessels still need coordination with state/security entities, the market may be pricing a binary on/off event when the real trade is a persistent friction tax on flows. That argues for fading any immediate collapse in energy volatility; the path of least resistance is a lower-volume, higher-variance regime until operators see several uninterrupted sailing days and a clear drop in insurance, escort, and delay costs.
