Oil Prices and Global Markets Reel as the Iran Crisis Deepens

London / New York / Dubai, May 19, 2026 — Brent crude surged $2.23 to $111.50 a barrel on May 18 a single session after Iranian strikes lit a fire at the UAE’s Barakah nuclear complex. WTI climbed $2.54 to $108.00. Gold, already trading near $5,300 an ounce, held its safe-haven premium. Treasury yields pushed toward 4.6 percent. And somewhere in the Gulf of Oman, 22,500 mariners remained stranded aboard more than 1,550 commercial vessels unable to transit a strait that has been functionally closed for 69 days.

This is what global market instability looks like when the iran crisis stops being a geopolitical abstraction and becomes a live arithmetic problem for every trader, refiner, central banker, and finance minister on earth.

The Oil Shock: From $70 to $138 and Where It Stands Now

When the US-Iran War began on February 28, 2026, with US-Israeli strikes that killed Supreme Leader Ayatollah Ali Khamenei and triggered Iran’s closure of the Strait of Hormuz, Brent crude was trading at $72.87. Within weeks, it had surged past $100. By April 7, it peaked at $138 a barrel a level last seen only in the most extreme supply crises in modern energy history. April’s average settled at $117. May has brought partial relief, with Brent retracing to the $102–$111 range, but each fresh Iranian strikes event snaps prices back toward the upper bound.

The IEA’s May Oil Market Report is unsparing: global oil supply has fallen by 3.9 million barrels per day across 2026. Production shut-ins averaged 10.5 million barrels per day in April the largest supply disruption in the history of the global oil market, surpassing 1973, 1979, and 2022 combined. The market is running an oil deficit of 1.78 million barrels per day for the full year. The IEA projects May–June Brent near $106 a barrel, with the steepest inventory draws of the entire conflict occurring right now.

Goldman Sachs has modelled a severe scenario in which persistent Strait closure keeps Brent averaging $120 in Q3 and $115 in Q4. JPMorgan has warned of $150 oil in worst-case scenarios. Morgan Stanley puts its severe scenario at $150–$180 a barrel if the Strait remains closed for months. Energy Aspects Director Amrita Sen, speaking to Bloomberg, warned that economies are “sleepwalking” into a “big recession” and described investor sentiment as showing “extremely misplaced euphoria” about the Iran crisis’s long-term damage.

Beyond Oil: LNG, Gold, Fertilisers, and Freight

The iran crisis has not confined its damage to crude oil. Every connected commodity market has been repriced.

LNG spot prices in Asia have surged more than 140 percent from pre-conflict levels. A March 18 strike damaged Qatar’s Ras Laffan facility one of 14 LNG trains reducing Qatar’s production capacity by 17 percent. At peak disruption, one-quarter of global LNG export capacity was offline. Prices are expected to trade above $26 per MMBtu through mid-June, with gas rationing already implemented in parts of Asia.

Gold spiked above $5,300 an ounce immediately after the February 28 strikes a 2-plus percent single-day jump from $5,100 and has held near record peaks as safe-haven demand from institutional investors, central banks, and retail buyers sustains the bid.

Fertilisers have been devastated. Anhydrous ammonia has risen from $828 per tonne before the conflict to $1,123 per tonne by April a 35 percent surge. The American Farm Bureau Federation estimates 70 percent of American farmers cannot afford the fertiliser they need. Thirty-five percent of the world’s urea supply originates in Gulf states; shortages are acute across Asia, Africa, India, Bangladesh, and Sri Lanka.

Shipping freight rates have tripled. The Strait of Hormuz handles 20–25 percent of seaborne oil and 20 percent of global LNG. With the strait effectively closed, vessels are rerouting around the Cape of Good Hope adding 3,500–4,000 nautical miles and 10–14 days to every voyage, compounding the oil price shock with a logistics cost shock across every supply chain on earth.

Equities: Resilient on the Surface, Fragile Underneath

The global market reaction to the US-Iran War has confounded many analysts. The S&P 500 closed above 7,400 for the first time ever on May 10 a record high reached while oil sat above $100 and the Strait of Hormuz remained closed. The Nasdaq held near 26,274. The Dow topped 49,700.

The explanation lies in composition: modern equity indices are dominated by technology companies whose earnings are largely insulated from energy input costs. Apple, Nvidia, Microsoft, and Meta do not run refineries. But the resilience is superficial when viewed through the lens of inflation, yield curves, and consumer spending power.

The US 10-year Treasury yield has risen nearly 24 basis points in a single week to approach 4.6 percent a level not seen in nearly a year as bond markets price in the inflationary consequences of sustained $110 oil. The ECB has warned that prolonged conflict will trigger stagflation across Europe, with technical recession risks for Germany and Italy by year-end. The ECB is now pricing in a June rate hike plus at least one more to contain an energy-driven inflation shock that monetary policy was not designed to absorb.

The IMF has cut its 2026 global growth forecast to 3.1 percent down 0.2 percentage points with an adverse scenario projecting 2.5 percent growth and 5.4 percent inflation, and a severe scenario of just 2 percent growth with inflation exceeding 6 percent.

The Signals Markets Are Watching

Every diplomatic development in the US-Iran War now moves prices in real time. The May 13–15 Beijing bingo summit between Trump and Xi Jinping which produced Xi’s endorsement of a stable Strait and China’s agreement to purchase American oil provided a brief $3–4 relief rally before the Iranian strikes on Barakah on May 17 erased the gains.

As Al Jazeera’s market analysis confirmed, traders are parsing every statement from Tehran, Washington, and Islamabad for ceasefire signals while simultaneously hedging against escalation. Trump’s “Clock is Ticking” post after Barakah, and a Situation Room meeting called for May 19 to discuss military options, sent the market back to risk-off mode overnight.

The IEA’s May report projects Q4 2026 Brent at $89 a barrel a forecast that implies a Strait reopening and Iranian production recovery. The EIA projects similar normalisation by year-end. Both forecasts carry an asterisk the size of a nuclear power plant: they assume diplomacy works.

It has not worked yet.
