Oil Prices Drop Faster Than Expected After Iran Peace Deal
Oil prices have fallen significantly faster than analysts anticipated following the signing of a preliminary peace agreement between the United States, Israel, and Iran in mid-June 2026, raising hopes that fuel costs could return to pre-war levels. A barrel of crude oil dropped nearly $10 in ten days, with US WTI crude trading around $69 per barrel and Brent crude at approximately $72 per barrel on June 26 — levels not seen since before the conflict began in late February, according to HLN’s liveblog.
Sharp Declines at the Pump
In Belgium, consumers are already feeling the relief. According to Het Laatste Nieuws, diesel prices dropped 11% in a single week to €1.92 per liter, while gasoline fell 8% to €1.80 per liter as of June 28. Maximum prices for gasoline (E10) hit €1.806 per liter — the lowest level since March 18, 2026.
“After the signing of the preliminary peace agreement, everyone expected the price to drop a bit, but not as sharply as is now the case,” said Johan Albrecht, energy economist at Ghent University (UGent) and the Itinera think tank, in an interview with HLN.
A Speculative Market Reaction
Despite the dramatic price drops, Albrecht cautions that the decline is primarily a speculative market reaction rather than a reflection of actual supply increases. The Strait of Hormuz — a narrow waterway through which approximately 20-30% of the world’s oil passes — has been only partially reopened, and hundreds of ships remain anchored waiting to transit.
“It is a purely speculative reaction of the market,” Albrecht explained. “It is clearly reacting optimistically to the signing of the preliminary peace deal. Yet the idea that oil can be transported again seems sufficient to lower prices.”
Full normalization of shipping through the Strait of Hormuz could take months, according to logistics experts. NU.nl reported in late May that US President Donald Trump had warned the blockade would remain in effect until a deal was actually finalized.
Fragile Peace, Uncertain Outlook
The interim peace deal, reportedly brokered with involvement from Pakistan, includes a US commitment to lift oil sanctions on Iran and Iran’s commitment to reopen the Strait of Hormuz, as NU.nl reported on June 12. However, multiple analysts emphasize the agreement’s fragility.
“I fear we are not yet ready for a full normalization of prices,” Albrecht said. “There is a preliminary peace deal, but it is very fragile.” Multiple incidents between Iran and the US have already occurred since the signing, and Iran briefly re-announced a blockade after Israeli strikes on Lebanon on June 22.
Albrecht identified Israel as the most unpredictable factor. “For me, Israel is the most unpredictable factor. And possibly that is also the case for the energy markets,” he told HLN.
Pre-War Context and Remaining Gap
Before the war, oil was trading at approximately $60 per barrel in early January 2026. The current level of around $70 still represents a $10 gap from pre-crisis prices. Analysts at Bank of America and Citi Group have lowered their forecasts, with Brent expected to average $75 for the second half of 2026.
The conflict, which began in late February 2026 when the US and Israel initiated military operations against Iran, caused oil prices to spike sharply above $90 per barrel. The war centered around Iran’s nuclear program and regional influence, with the blockade of the Strait of Hormuz causing massive disruptions to global energy supply chains.
Broader Implications
The crisis has reinforced arguments for accelerating the energy transition. Albrecht noted that “after the war in Ukraine, we already knew that renewable energy and electrification were important, but this crisis has underscored that even further.”
Belgian authorities have also taken action. Ministers Rob Beenders (Consumer Protection) and Mathieu Bihet (Energy) introduced measures to combat misleading energy contract practices, including a ban on deceptive welcome discounts that lock consumers into expensive contracts.
What to Watch For
The key question remains whether the fragile peace will hold. If violence escalates and Iran re-closes the Strait of Hormuz, all price declines could be reversed in an instant. The coming weeks of negotiations between the US, Israel, and Iran will be critical in determining whether European consumers can expect sustained relief at the pump or whether the energy crisis will flare up once again.
As Albrecht summarized: “We are still in the middle of it. There are no guarantees that all parties will truly silence their weapons in the coming weeks and months.”
