VLCC freight rates nearly doubled in a single week to an all-time record — and the insurance collapse means the cost persists even after the shooting stops.

Key takeaway

The decoupling of the insurance timeline from the military timeline creates a second, commercial blockade that will persist independently of any ceasefire, because P&I clubs and hull underwriters cannot restore War risk coverage in less than several weeks regardless of battlefield developments.

Very Large Crude Carrier freight rates hit $423,736 per day on 7 March — a 94% increase from the prior Friday close and the highest figure ever recorded. At these rates, shipping costs alone add approximately $3–4 per barrel before crude reaches a refinery, a surcharge passed through to refiners and, ultimately, to consumers at the pump.

The rate reflects physical scarcity, not speculation. More than 150 vessels sat at anchor in The Gulf of Oman and Arabian Sea as of 5 March, unable to transit the strait of Hormuz. Every major P&I club's War risk coverage expired at midnight on 5 March; no new commercial transits were documented after the deadline. Trump's promised DFC insurance programme and Navy convoy escorts remain non-operational — the US Navy has not conducted a single escorted passage. Shipping consultancy Simpson Spence Young assessed Navy convoys as "unlikely in the near-term" given simultaneous combat demands.

The freight market has priced in something political analysts have been slower to articulate: the energy disruption runs on two separate timelines. The military timeline could theoretically end with a ceasefire. The insurance timeline cannot. P&I reassessments typically take weeks regardless of battlefield developments. Even if hostilities ceased today, commercial shipping would not resume until underwriters complete their reviews and agree to cover vessels transiting waters where the IRGC struck the Sonangol Namibe — a Bahamas-flagged Angolan state oil company tanker — causing a cargo tank rupture and oil spill just 30 nautical miles from Kuwait.

Every day the strait remains closed, the available global VLCC fleet shrinks as vessels queue outside The Gulf instead of cycling through it. Routes bypassing Hormuz — the Cape of Good Hope for Gulf-to-Europe cargoes, trans-Pacific alternatives — are longer, tying up tankers for additional weeks per voyage and compounding the shortage. The freight rate is not a war premium that dissipates with a ceasefire. It is the market's recognition that the physical infrastructure of global oil transport has been dislocated in a way that does not reverse on the day the missiles stop.

Deep Analysis

In plain English

Very Large Crude Carriers (VLCCs) are the supertankers that move most of the world's oil — each carries roughly 2 million barrels. Their daily hire rate just hit a record of over $400,000, nearly double a week ago. The more consequential fact: commercial shipping insurance for The Gulf war zone effectively expired on 5 March, and reassessing it takes weeks. This means commercial ships will not enter the region even if shooting stops tomorrow. The war has created two separate blockades — one military, one commercial — and only one of them can be ended by a ceasefire.

Deep Analysis

Synthesis

The combination of all-time-high freight rates and structural insurance withdrawal creates a two-layer blockade: one physical (Iranian military activity), one commercial (insurance market failure). These layers operate on different timelines and respond to different interventions — meaning any ceasefire framework that addresses only the military layer will leave the commercial blockade intact. A durable economic resolution requires explicit mechanisms for restoring commercial insurability, not merely a halt to hostilities.

Root Causes

Global P&I insurance is concentrated in thirteen clubs comprising the International Group of P&I Clubs, which collectively cover approximately 90% of world merchant shipping by tonnage. Their simultaneous withdrawal of War risk coverage creates a structural market failure with no private-sector alternative at comparable scale — a single point of failure embedded in the architecture of global trade that pre-dates this crisis by decades and reflects a historical assumption that major transit straits would remain navigable under great-power deterrence.

Escalation

VLCC rates at $423,736/day make Cape of Good Hope rerouting economically viable despite adding approximately 14 days and $500,000–700,000 in additional bunker costs per voyage. However, the global VLCC fleet cannot simultaneously serve both normal Hormuz-routed demand and full Cape rerouting without effective capacity reduction, meaning the volume of oil reaching Asian refiners will decline regardless of price — the physical constraint, not cost, is the binding variable.

What could happen next?

Consequence
A ceasefire alone will not restore commercial shipping through Hormuz — P&I and hull war risk insurance timelines require weeks of formal reassessment regardless of battlefield developments, maintaining the effective commercial blockade.
Short term · Assessed
Risk
Asian refinery throughput may begin declining within 2–4 weeks as strategic petroleum reserves are drawn down and Cape-rerouted alternative supply proves insufficient to replace full Hormuz transit volumes.
Short term · Suggested
Precedent
The simultaneous expiry of all major P&I war risk policies demonstrates that commercial insurance markets can enforce a de facto naval blockade without any military action — a dynamic relevant to future crisis planning and deterrence doctrine.
Long term · Suggested
Consequence
Shipowners operating VLCC capacity on Cape rerouting receive record freight income while bearing higher operating costs — a windfall concentrated in fleet owners based in Greece, Japan, South Korea, and Norway that partially offsets those countries' higher import costs.

Source Landscape

This story draws on mixed-leaning sources from United States and Serbia

United States

Serbia

The 1984–1988 Tanker War — the subset of the Iran-Iraq War targeting Gulf shipping — is the direct structural precedent.

Lloyd's of London suspended normal war risk underwriting for Gulf routes in 1984, and the 'Gulf Add' war risk premium reached 0.25–0.5% of hull value per voyage. The US Navy's Operation Earnest Will (1987–1988) ultimately reflagged Kuwaiti tankers under the Stars and Stripes specifically to force naval escort and deter Iranian attacks — the last occasion on which commercial shipping viability in The Gulf required direct superpower military intervention to restore.

Why it’s relevant now

Operation Earnest Will's resolution required diverting significant US naval assets to convoy escort duty; replicating that approach in 2026 would require pulling warships currently committed to offensive strike operations, creating a direct and unacknowledged resource trade-off for CENTCOM planners.

Cape of Good Hope rerouting adds roughly 14 days per voyage for Gulf-to-Europe and 10+ days for Gulf-to-Asia routes.

At $423,736/day hire plus $500,000–700,000 additional bunker fuel per voyage, a single VLCC Cape rerouting costs approximately $6.5–7.5 million more than a Hormuz transit.

Applied across the estimated 15–20 VLCCs per day that would normally transit Hormuz, the daily incremental shipping cost of rerouting the entire flow exceeds $100 million — a cost ultimately borne by end consumers through refined product prices and one that persists for the duration of any Hormuz closure irrespective of ceasefire.

The Joint War Committee (JWC) of Lloyd's Market Association designates high-risk areas for hull war risk purposes; The Gulf is currently listed and cannot be delisted without a formal JWC review process requiring sustained evidence of threat reduction — a process with no mandatory timeline and typically measured in weeks to months.

Maritime law practitioners note that shipowners entering a JWC-listed zone without valid war risk hull cover risk voiding their entire P&I third-party liability cover, creating catastrophic liability exposure that dwarfs any freight rate premium and effectively eliminates commercial risk appetite regardless of insurance cost.

This Event

Supertanker rates hit $424k/day, up 94%

Record supertanker rates expose the energy disruption's two-timeline problem: military hostilities could theoretically end with a ceasefire, but the P&I insurance collapse cannot. Freight markets are pricing in weeks of continued disruption regardless of the battlefield, and every day the strait stays closed shrinks the available global tanker fleet as vessels queue rather than cycle.
