A massive global oil glut is imminent and projected to hit the market as major energy agencies forecast a looming supply surplus that could exceed 4 million barrels per day by 2027.
After a naval blockade agreement and peace deal were reached, crude prices quickly retreated.
On Wednesday, oil prices were hovering near $76 to $79 per barrel, easing from earlier highs as markets react to a U.S.-Iran peace deal and expanding global supplies. West Texas Intermediate, the U.S. benchmark, trades were around $76.50 per barrel, while global benchmark Brent Crude trades near $79.50 per barrel. Prior to the war, benchmark crude was trading in the range of $67 to $72 per barrel, with global crude prices briefly touching a wartime peak of roughly $126 per barrel.
According to Financial Times, an oil glut often follows shortage because high prices during the shortage trigger 'demand destruction' while simultaneously incentivizing a surge in global production. When geopolitical conflicts or supply chain blockages such as those in the Strait of Hormuz are resolved, supply recovers rapidly, creating a market oversupply.
During a shortage, soaring energy and fuel prices naturally force consumers, businesses and industries to cut back on consumption or transition to alternative energy sources, permanently lowering overall demand, as well as incentivizing producers worldwide to maximize output, drill new wells, and revive dormant oilfields, according to the International Energy Agency (IEA).
Governments and global entities often release massive amounts of emergency oil stockpiles to stabilize prices during a crisis. When normal trade routes reopen, both these emergency supplies and commercial supplies hit the market at the same time The war is estimated to have blocked more than 14 million barrels per day (bpd) of Middle East oil output according to the IEA.
The IEA forecasts suggest that supply “will come in around “ 920,000 bpd below total demand in 2026, narrowing from a 1.78 million bpd deficit in the previous month's report, and the 2027 supply will outweigh demand by 5.05 million bpd, as demand growth is overshadowed by supply ramping up as Middle East barrels return.
Inventories have fallen at a rate of 3.8 million bpd since the start of the war on February 28, with stock draws in May alone at around 4.6 million bpd, according to preliminary IEA data.
The United States and Iran have agreed to a 60-day ceasefire and signed a Memorandum of Understanding aimed at reopening the Strait of Hormuz and initiating broader nuclear and regional negotiations, with President Trump writing on social media that “oil will flow,” once the deal is signed. Iranian Deputy Foreign Minister Kazem Gharibabadi confirmed that the text of a memorandum had been finalized and that a formal signing ceremony would take place in Switzerland on Friday, as well as Pakistan and Qatar, the two lead mediators in the deal, also confirming the agreement.
Importantly for oil markets, Iran will be able to resume crude exports during the 60-day ceasefire period while broader nuclear negotiations continue.
