The 2026 Oil Price Crash: How a Ceasefire Unleashed a Chaotic Supply Surge

How Much Have Brent and WTI Fallen?

The scale of the decline was dramatic. Brent crude fell from a wartime peak around $105–$115/bbl in Q2 2026 to settle at $77.18/bbl on June 18, then dropped further to near $70/bbl by late June. It posted a roughly 30% decline in Q2 2026 — its largest quarterly drop since 2020 . WTI briefly dipped below $70/bbl on June 24, the first time since before the Iran conflict, and by June 30 was trading around $69.94/bbl, down 24.12% over the prior month . Brent fell 9% in a single week in mid-June and saw single-day drops of over $3 (4.3%) on June 24 .

How Quickly Has Persian Gulf Production Recovered?

The recovery was much faster than initial EIA and analyst expectations, though full restoration is still underway.

• Rystad Energy estimated that shut-in production across the six main Gulf producers had dropped to 9.6 million bpd by mid-June 2026, down from a peak loss of 24.2 million bpd versus pre-war levels. Rystad expects full regional supply restoration by the end of 2026, with the UAE and Saudi Arabia leading the recovery .
• Middle East crude production rebounded to between 14.6 and 15 million bpd in late June .
• Saudi Arabia and Kuwait were among the first to restart halted output and resume liftings. Bloomberg reported that Kuwait was already lifting products and moving tankers through the strait in early June .
• The IEA reported global oil supply was still 13.6 million bpd below pre-war levels in May, but the ceasefire framework was expected to support a "gradual recovery" .

What Three Key Developments Drove the Faster-Than-Expected Supply Rebound?

1. Immediate tanker exodus from the Strait of Hormuz: Dozens of oil tankers that had been stuck for months began departing the Persian Gulf as soon as the ceasefire was signed. Over 20 oil tankers exited in the first days, and around 31 supertankers carrying ~62 million barrels of trapped crude were poised to flood the market .

2. US lifting of the naval blockade on Iran: This allowed Iranian crude exports to resume almost overnight, adding millions of barrels per day of supply that the market had not fully priced in .

3. OPEC+ pre-agreed output increase: OPEC+ had already agreed in April 2026 to boost production once the Strait reopened, and key Gulf states (Saudi Arabia, UAE, Kuwait) had idle capacity ready to bring online quickly .

How Have Analysts and Barclays Revised Their 2026 Oil Price Forecasts?

The speed of the recovery forced major banks into a rapid series of downgrades. Barclays' trajectory illustrates the whiplash: on March 13, 2026, it raised its Brent forecast to $85/bbl due to the Strait of Hormuz disruption ; by May 1–22, 2026, it raised it further to $100/bbl, warning prices could go higher ; on June 16, 2026, it maintained the $100/bbl forecast with an end-June baseline for Hormuz reopening ; and on June 26, 2026, it cut its 2026 Brent forecast to $96/bbl (from $100) and its 2027 forecast to $85/bbl (from $88), citing the "rapid recovery of oil flows through the Strait of Hormuz" .

Other banks also adjusted quickly. J.P. Morgan revised its Brent forecast lower for the latter half of 2026 following the Hormuz reopening . Goldman Sachs had earlier projected 2026 Brent at $56/bbl and WTI at $52/bbl, and maintained that supply would "largely rebound within months" after a full Hormuz reopening . The EIA had projected Brent peaking at $115/bbl in Q2 2026 before easing, a view that was rapidly overtaken by events .

What Unusual Trade Flows Have Emerged?

• A "chaotic" wave of trapped oil hitting Asia: Around 31 supertankers (~62 million barrels) that had been stuck inside the Strait of Hormuz were suddenly released, creating a "race to liberate trapped volumes" that swamped Asian refiners who had spent months sourcing alternative barrels from the Atlantic Basin and the US .

• Reverse flow from Atlantic Basin back to Europe: During the Hormuz closure, Asia had scrambled to buy US and West African crude. With Gulf supply surging back, some of those non-Middle Eastern cargoes were being re-routed or backed up, creating logistical congestion .

• Iranian oil moving again through unusual channels: The NYT reported that Iranian oil was transiting the Strait of Hormuz under a new routing pattern, with "numerous ships" moving Iranian crude after the blockade was lifted .

• Tanker "dark" transits: Some tankers used AIS dark zones to transit the Strait even before the formal reopening, signaling that black-market or sanctioned oil flows were accelerating in anticipation of the deal .

• Massive destocking: With over 20 oil tankers departing the Gulf in the first wave, Kpler data showed an abrupt surge in available floating storage being discharged into the market .
