ConflictDeveloping

The oil tanker MV Skylight was struck off the coast of Oman in waters near the strait of Hormuz, injuring four crew members. The attack is the first confirmed hit on a commercial vessel since the IRGC broadcast its "no ships may pass" closure on VHF Channel 16 at the conflict's outset . Two other vessels — MKD Vyom, which suffered an engine room fire from a projectile strike, and Sea La Donna, details still pending — were also attacked in the same period. In hours, the strait moved from a zone shipping companies were avoiding voluntarily to one where vessels were under direct fire.

The economic consequences arrived immediately. Vessel traffic through the strait fell 70%. More than 150 tankers sat at anchor in open Gulf waters. CMA CGM, Maersk, Hapag-Lloyd, Nippon Yusen, Mitsui, and Kawasaki Kisen all halted transits. CMA CGM imposed an emergency surcharge of $2,000–$4,000 per container, effective immediately. Brent Crude stood at roughly $73 before the first strikes and opened Saturday at $82.37 — a price set before the tanker attacks. Goldman Sachs had forecast a peak of $110; JP Morgan projected $120–$130 for a prolonged conflict and raised its US recession probability to 35% . With merchant vessels now absorbing hits, those figures look like floor estimates rather than worst-case scenarios.

The last sustained military campaign against commercial shipping in these waters was the 1984–88 Tanker War during the Iran-Iraq conflict. Over four years, 546 vessels were struck; insurance premiums tripled; Kuwait reflagged its tankers under the US flag to secure naval escorts. Three vessels have been hit here in 72 hours. The modern global economy is more exposed than it was in the 1980s — roughly 20% of the world's traded oil and a quarter of global LNG transits the strait daily. Alternative routes exist: the Saudi east-west pipeline, the UAE's Habshan-Fujairah bypass. Neither can handle more than a fraction of normal throughput. Mohsen Rezai, secretary of Iran's Expediency Council, had declared the strait "officially open" while simultaneously calling US warships "legitimate targets" . The four injured crew of the MV Skylight are the first evidence of what that contradiction looks like in practice.

Deep Analysis

Synthesis

The clustering of tanker attacks with simultaneous strikes on Gulf cities raises a key interpretive question: co-ordinated strategy to make the Gulf economically ungovernable, or simultaneous activation of pre-positioned capabilities by units operating without central direction. Either reading is alarming. Co-ordination implies deliberate escalation to maximum economic pressure. Autonomous execution implies Iran's most strategically significant weapons are in the hands of commanders without current political direction. Regardless of how the immediate conflict resolves, the longer-term consequence may be a permanent re-evaluation by Asian and European energy consumers of Gulf supply dependence, accelerating strategic reserve expansion and energy transition investment.

Root Causes

Attacking the strait distributes economic pressure across non-belligerent states — Japan, South Korea, India, China, European importers — creating an incentive structure for third-party governments to lobby for de-escalation regardless of their own political positions. The costs land primarily on states that had no role in the conflict's initiation. Some attacks may also reflect localised IRGC naval unit decisions rather than centralised direction, which would make them harder to terminate through negotiated agreement even if political will for de-escalation emerged.

Escalation

The US Navy's Fifth Fleet has substantial Gulf assets and a historical doctrine of protecting commercial shipping. However, its forces are currently committed to offensive strikes against Iranian military targets. If tanker attacks continue, the US faces pressure to divert naval resources to escort duties — which creates a direct US-Iran naval confrontation scenario separate from the air campaign already under way.

What could happen next?

2 consequence2 risk1 precedent

Consequence
Vessel traffic through the Strait of Hormuz has fallen 70% within 72 hours of the first tanker attack, removing approximately 12–14 million barrels per day of oil transit from global supply chains.
Immediate · Reported
Risk
If tanker attacks continue at the observed pace, US naval doctrine creates pressure for escort operations that could generate a direct US-Iran naval confrontation, independent of the air campaign dynamic.
Short term · Assessed
Consequence
Consumer energy prices in Europe, Asia, and North America are likely to begin rising within weeks as current supply stockpiles are drawn down and the forward curve in oil futures reprices.
Short term · Assessed
Risk
If Iranian military units are operating without central command authority, the political mechanism required to order a halt to tanker attacks — and thus to restore shipping confidence — may not currently exist, making the economic disruption structurally harder to terminate than in a conventional state-directed confrontation.
Short term · Suggested
Precedent
The return of active combat against commercial shipping in the Strait of Hormuz for the first time since the 1980s Tanker War will permanently elevate risk premiums and insurance costs for Gulf transit, incentivising long-term investment in alternative supply routes and strategic reserve capacity regardless of how this conflict resolves.

This story draws on mixed-leaning sources from United States

United States×2

The US response to the 1984–88 Tanker War culminated in Operation Earnest Will (1987): Kuwait reflagged its tankers under the US flag to qualify for naval escorts.

The operation ended badly — the USS Vincennes shot down Iran Air Flight 655 in July 1988, killing 290 civilians — a precedent that complicates the domestic political calculus for any administration considering a repeat.

Why it’s relevant now

Operation Earnest Will is directly relevant as a precedent for the US naval response option — but the Vincennes incident illustrates that naval escort operations in contested Gulf waters carry a documented risk of catastrophic miscalculation that could independently generate a major escalatory incident.

Asian economies — Japan, South Korea, and India — collectively import approximately 55–60% of their oil from Gulf States and face the most acute direct exposure; their sovereign bond markets and equity indices will price this in near-term sessions.

Tanker equities (Frontline, Euronav, DHT Holdings) will see sustained upward pressure alongside Brent and LNG spot prices for as long as commercial transits remain suspended.

The US Strategic Petroleum Reserve was substantially drawn down during the 2022 energy crisis and not fully replenished, limiting Washington's ability to dampen price effects as it did in 1991.

US Naval War College doctrine specialists have noted that Operation Earnest Will established convoy escort precedent against a state with intact command structures — the current scenario of Iranian units potentially operating without central political authority makes rules-of-engagement calculations significantly less predictable.

The International Maritime Organisation has no formal mechanism for compelling states to ensure safe transit through contested waters; commercial shipping protection depends entirely on naval power-projection by states willing to provide it.

This Event

Tanker MV Skylight hit near Hormuz

The attack on commercial shipping transforms the Hormuz crisis from a broadcast closure — which markets could treat as potentially temporary — into an active combat zone where merchant vessels face direct military attack. This converts a geopolitical risk premium into sustained physical supply disruption.

Different Perspectives

Turkiye

Erdogan followed the Pakistani delegation to Jeddah for an instrument that has not been signed. Ankara's entry widens Saudi Arabia's defence architecture beyond the existing Pakistan pact, adding a second non-Gulf military partner mid-conflict.

Oman

Muscat is the corridor's broker but has published nothing about the arrangement Fars describes on its behalf. The account leaves Oman administering outbound traffic only, a narrower role than the shared route its mediation has rested on since 1979.

Pakistan

Islamabad sent Sharif, Munir and Dar to Jeddah to widen a defence commitment it has honoured in cheaper registers since March, when Dar invoked the Saudi mutual defence pact. Jeddah tests whether that hedge becomes a binding trilateral instrument with Turkiye.

United States

Washington rejected the Majlis Hormuz bill outright while CENTCOM's own tally kept climbing to 49 vessels redirected since 14 July. Both instruments tightened in the same week Trump promised the strait would reopen soon.

Iran

Iran's foreign ministry is selling a phased Hormuz corridor through Oman and denying any percentage cargo tariff, while its own Majlis is legislating fines to 20% and a bar on Israeli-linked cargo. The two accounts, from the same government, do not agree with each other.

Saudi Arabia

Riyadh published a target forecast, not an attribution, for the campaign it says the Najran strike previewed. That keeps an Article 51 case available while it formalises a trilateral defence architecture with Pakistan and Turkiye.
