Iran lifts petrochemical export ban, adding supply to tight market

Tehran's reversal of a three-month export ban on petrochemicals will release additional supply into a global market already grappling with shifting crude flows and refining bottlenecks.

Iran's customs authority on July 13 lifted an emergency ban on exports of chemicals, polymers and petrochemical products, reversing a restriction imposed during the Strait of Hormuz crisis and freeing up supply for international buyers. Export controls on industrial tallow and sulfonic acid remain in effect, according to the directive reported by CCTV.

"The removal of export restrictions signals Iran's intent to restore revenue streams after months of disrupted trade, though the broader market remains constrained by ongoing hostilities around the strait," said Ole Hansen, head of commodity strategy at Saxo Bank.

Brent crude has rebounded from $71 to $79 a barrel after managed-money net long positions on the benchmark fell to just 55,600 contracts in late June, down 87% from a March peak of 429,000, with gross shorts hovering near an all-time high of 226,000 contracts, according to Saxo Bank data. The extreme short positioning left crude vulnerable to a squeeze as geopolitical risks escalated.

The petrochemical export ban was originally imposed after Iran's closure of the Strait of Hormuz in early March, a move that disrupted roughly a fifth of the world's traded crude oil and natural gas. Beijing responded by banning domestic exports of refined petroleum products and slashing foreign crude purchases, effectively neutralizing the supply shock and keeping a lid on prices. That demand freeze has now thawed: Chinese refiners have secured 26 million barrels for July and August delivery from Gulf Cooperation Council producers, according to Argus data, and licensed refineries are projected to export roughly three million tonnes of refined fuel this month.

The Clearing of Floating Storage and the Waiver Reversal

The easing of physical supply constraints was reinforced by a rapid drawdown of floating storage. Crude and condensate stored on vessels in East Asian waters plunged from 49.02 million barrels in May to 24.45 million barrels by the end of June, a decline of roughly 50%, as a large overhang of Iranian crude accumulated since late 2025 was absorbed by the market, according to S&P Global Commodities. The drawdown was driven by a 60-day U.S. general sanctions waiver introduced alongside a mid-June peace framework, which temporarily removed logistical barriers to seaborne Iranian oil exports.

That waiver has now been canceled, abruptly cutting off the legal flow of those barrels and reinstating strict maritime enforcement. The brief window of physical liquidity is already slamming shut, even as Iran's government approved a comprehensive support package to assist economic enterprises damaged by U.S.-Israeli attacks, according to the AhlulBayt News Agency.

What's at Stake for Global Supply

The timing of Iran's export ban reversal is critical. Global diesel markets are tightening as Russia's ban on foreign fuel sales — a direct result of Ukrainian drone strikes that cut Russian diesel exports in half year-over-year — removes a key source of supply. Increased Chinese diesel exports will act as a necessary offset to this structural deficit rather than oversupplying the market, according to the Oilprice.com analysis.

The last time Iran imposed and then lifted export restrictions during a period of elevated geopolitical risk, in 2019, crude prices swung by more than $15 a barrel over a three-month period as supply expectations shifted faster than physical barrels could reach buyers. A similar pattern may unfold now, with the petrochemical export resumption adding supply to a market where Brent's brief flirtation with contango masked critically low inventories and a massive return of Chinese demand.
