Norwegian Insurers Hold Hormuz Terms Steady as Talks Drag On
Two Norwegian shipping underwriters told Montel on Tuesday (2026-06-23) that war-risk terms for tankers in the Persian Gulf remain unchanged despite the latest round of Iran-US negotiations, keeping the effective cost of a Hormuz transit well above most operators' break-even.7
The gap between geopolitical process and commercial reality matters. An insurer's unwillingness to rerate is the clearest signal that Hormuz remains operationally shut for most commercial traffic, regardless of what negotiators in Washington or Tehran may announce. Insurance terms are set on evidence of physical risk, not on ceasefire announcements.
The war-risk market had already digested a run of mixed signals. President Trump announced a two-week ceasefire between the United States and Iran on Wednesday (2026-05-20), triggering a sharp reversal in energy prices. ICE Brent crude front-month fell 13.3% that day to $94.75, its largest one-day decline since 2020, while the Nasdaq Composite closed up 2.8%.3 But that price move did not translate into easier insurance terms. By Monday (2026-05-18), vessel tracking data showed just one ship exiting the Gulf while two entered — a near-standstill that underscored how little the diplomatic news had changed conditions on the water.4
The price of attempting a voyage has remained prohibitive. Argus Media data showed US, UK and Israeli-affiliated ships being charged war-risk premiums as high as 5%, making a single voyage for a $150 million tanker cost up to $7.5 million in insurance alone.5 Iran added a further layer of cost by demanding transit fees of up to $2 million per ship, payable in cryptocurrency or Chinese yuan.5 Together, those costs push the economics of most voyages into negative territory.
The LNG market has borne this most acutely. The Strait of Hormuz handled roughly 20% of global LNG supply before the US-Israel conflict with Iran began on 28 February, at which point it came to an effective halt for laden carriers.2 One crossing occurred in the weeks after the ceasefire announcement, but analysts told Montel that further laden voyages were unlikely in the near term absent a durable regional settlement.2
Those dynamics help explain the current tape. ICE Brent crude front-month sits at $77.06 as of Tuesday (2026-06-23), well below the above-$100 levels seen during the acute phase of the blockade but still pricing in residual risk. JKM — the benchmark for Asian spot LNG — stands at $15.86, reflecting the continued diversion of Middle East cargoes around the Cape of Good Hope rather than through the strait. ICE Endex TTF front-month is €41.67.7
Energy markets described the situation as "fragile, uncertain" even after the ceasefire extension was announced, analysts told Montel on Wednesday (2026-05-20).1 That read has not changed. The structure of the insurance market suggests underwriters are calibrating to a scenario in which talks continue indefinitely without delivering the clearances that would enable a resumption of normal traffic.
A Poten & Partners executive told Montel that Iran had little incentive to forge a swift deal while its grip on Hormuz continued to reverberate through global energy markets.6 Until war-risk underwriters in Oslo and elsewhere see evidence of de-escalation on the water — not in diplomatic communiques — tanker economics through the Persian Gulf will not normalize.
The indicator to follow is the insurance market itself, not the diplomatic calendar. A reduction in war-risk premiums below the 5% level currently quoted for high-flag-risk vessels would signal genuine de-escalation. Until that happens, Hormuz remains physically shut to most commercial traffic, irrespective of what either side's negotiators say next.
