Prices Have Nearly Tripled

Group III base oil prices have nearly tripled compared with prewar levels, reaching about $4,000 per tonne in Europe and the US . In Europe specifically, prices climbed from roughly €1,000/ton in February to approximately €3,500/ton by July 2026 . The Independent Commodity Intelligence Services (ICIS) described the situation as particularly acute for Group III, where recovery timelines are significantly longer due to structural disruptions — including the Pearl GTL outage .

A Structural Shortage, Not Just a Shipping Problem

Nearly 44% of the Group III base oil used globally in motor oil comes from just three Persian Gulf producers — all locked behind the Strait of Hormuz closure . This created an immediate structural shortage that a Hormuz reopening alone cannot fix, because the Pearl GTL outage is a separate, lasting production loss. Even after a ceasefire, total Group III supply for the year is expected to remain well below normal capacity, with stabilization not expected until the end of 2026 or early 2027 .

Automakers Feel the Pinch

Toyota and Nissan have issued dealer bulletins rationing 0W-20 and 5W-30 synthetic oil, with Group III supply running roughly 44% below normal capacity . Major carmakers have scrambled to secure alternative supply and avert production-line stoppages. The Financial Times reported that the world's largest carmakers are urgently seeking to avert a motor oil crisis .

Petrochemical Sector & Polyethylene: A $20–25 Billion Trade at a Standstill

Roughly $20 billion to $25 billion worth of petrochemicals and polymers from the Middle East typically transit the Strait each year. That trade ground to a near-halt after the closure .

By late March 2026, roughly 50% of global polyethylene capacity was either directly offline or indirectly constrained through feedstock shortages . Plastic and polymer prices surged to roughly four-year highs, affecting everything from auto parts to toys . The Middle East accounted for over 40% of global polyethylene exports in 2025, making the disruption especially severe .

S&P Global Platts reported in July 2026 that a swift return to prewar trade volumes for Middle East chemicals is improbable; shipping bottlenecks will persist through at least the second half of the year . ICIS estimated that even after the Strait fully reopens, it will take 12 to 18 months for Middle East polymer exports to fully recover .

Fertilizer Prices: A 20% Global Rise Threatens Food Supply

Fertilizer markets took an enormous hit because the Gulf region is a major exporter of urea, ammonia, and phosphates. About one-third of global seaborne fertilizer trade typically passes through the Strait of Hormuz .

United Nations data shows that between April 2025 and April 2026, urea exports from the region declined by 83% . Ammonia exports fell 75%, and methanol exports dropped 80% .

Price Spikes and Food Security Risks

As of mid-March 2026, DAP and MAP had risen above $700/MT, urea above $600/MT, and UAN above $400/MT . The FAO projected fertilizer prices would rise 20% overall in 2026, intensifying pressure on global food supply chains . The World Bank's fertilizer price index rose more than 12% in Q1 2026, reaching its highest level since October 2022 .

University of Illinois analysis projected urea peaking at $782/short ton in June 2026 even under a "Quick Reopening" scenario, and significantly higher — up to $996/short ton — under an "Extended Conflict" scenario .

Industrial Gases: Helium and Neon Collateral Damage

The UN has documented severe disruption to industrial gas exports from the region. The indirect effect on helium — a byproduct of natural gas processing — is acute: natural gas exports through the Strait dropped by 95% . Qatar supplies roughly 30% of the world's helium, a critical input for semiconductors, medical imaging (MRI), and aerospace . With LNG and gas processing effectively halted, helium production and export capacity collapsed. Spot helium prices doubled in the first month of the crisis and were projected to surge another 25–50% if disruptions persisted .

Neon supply chains — critical for laser lithography in chipmaking — also faced disruption as a knock-on from constricted petrochemical and industrial gas logistics .

Commercial Shipping at a Near-Standstill

Insurance has become unavailable or prohibitively expensive for vessels transiting the Strait, and seafarers refuse to make the journey. Commercial shipping is at a near-standstill except for a tiny number of vessels paying exorbitant "passage fees" to the Islamic Revolutionary Guard Corps .

The UN reports combined export volumes for 12 tracked product categories fell by 54% between April 2025 and April 2026 . The Pentagon testified on April 21, 2026, that fully clearing the Strait of mines and debris would take an estimated six months .

Oil Price Volatility: The Largest Supply Shock in History

Brent crude jumped 8% from $71.32/bbl on February 27 to $77.24/bbl on February 28 alone . Brent later climbed above $100 per barrel multiple times, reaching a peak of $138/bbl in April before settling around $106/bbl after a ceasefire . By July 2026, crude was trading above $100/bbl again after Iran rejected a US ceasefire proposal .

The World Bank's April 2026 Commodity Markets Outlook projected a 16% rise in average commodity prices for 2026 — the first annual increase since 2022 — driven primarily by the Hormuz closure . The supply shock was described as three to five times larger than the 1973 Arab oil embargo or the 1990 Gulf War in terms of volume removed from global markets .

Beyond the Headlines: Key Data Points

Recovery: A Year or More, Even Under Optimistic Scenarios

The crisis has two separate recovery timelines that do not move in lockstep. The Strait itself could reopen to shipping within six months of active clearing operations . But the Group III base oil crisis has a separate, longer clock: Shell's Pearl GTL repair alone is estimated at one year . Even after a ceasefire, ICIS expects a six- to nine-month period before stabilization, meaning a return to normalcy is likely not until the end of 2026 or early 2027 .

For polyethylene and broader petrochemicals, ICIS estimates a 12- to 18-month recovery for Middle East polymer exports after reopening, encompassing ceasefire terms, insurance market normalization, carrier service resumption, and inventory rebuilding across the entire chain .

The cascading consequences — from tripled synthetic motor oil prices and automaker rationing to 83% declines in fertilizer exports and a near-total halt to commercial shipping — make this clear: the Hormuz closure has triggered the largest energy supply shock since the 1973 oil crisis, and the recovery will be measured in years, not weeks.
