Key Takeaways
- Brent crude futures are headed for a 19% monthly loss, marking the most significant decline since 2020, driven by advancing U.S.-Iran diplomatic discussions.
- Washington and Tehran have preliminarily reached consensus on extending their current truce for an additional 60 days, subject to final authorization from President Trump.
- Maritime traffic through the Strait of Hormuz continues to face constraints, though normalization prospects improve if agreements are finalized.
- American distillate inventories have reached their most depleted levels in more than twenty years during the persistent supply disruption.
- Market experts caution that even with a diplomatic resolution, restoring normal oil flows may require several months due to damaged infrastructure and shipping complications.
Crude oil markets are experiencing significant downward pressure this month as market participants digest emerging reports of a possible truce extension between Washington and Tehran. Brent crude futures declined toward the $92 per barrel mark on Friday, representing approximately a 19% loss for May. West Texas Intermediate similarly retreated to near $87. Both benchmarks are tracking their most pronounced weekly losses in recent months.

The price action follows emerging information that U.S. and Iranian negotiators have formulated a framework to prolong their current ceasefire arrangement by an additional 60-day period. Final endorsement from President Donald Trump remains outstanding. White House officials have refrained from publicly validating the agreement’s specifics.
Vice President JD Vance informed media representatives that determining “when or if” a final agreement materializes remains premature. Treasury Secretary Scott Bessent offered limited commentary, acknowledging merely that “the teams have been going back and forth.”
The Critical Role of the Strait of Hormuz
Central to the current energy crisis is the Strait of Hormuz, a strategic chokepoint responsible for facilitating a substantial portion of international petroleum transport. Following the onset of hostilities, reciprocal blockade measures implemented by both Washington and Tehran have eliminated millions of daily barrels from global supply channels, precipitating a worldwide energy disruption.
Vessel movement through this critical passage continues operating substantially beneath pre-conflict volumes. Even reporting from Axios suggesting maritime activity would become “unrestricted” under the anticipated agreement has failed to generate complete market confidence.
Petroleum prices experienced temporary declines Thursday following reports of renewed military engagements between American and Iranian military units, subsequently rebounding as diplomatic communications resumed.
Why Immediate Supply Recovery Remains Unlikely
Industry analysts emphasize that any ceasefire extension would not trigger immediate restoration of normal oil transportation. Multiple practical challenges persist.
Explosive ordnance in the Hormuz waterway requires removal. Oil fields that underwent emergency shutdowns may necessitate months for restart procedures. Critical infrastructure compromised by unmanned aerial vehicle and missile attacks requires extensive repairs. Additionally, petroleum tankers would still require weeks to complete voyages to consuming nations.
“I would expect flows to remain heavily constrained due to the time lag of tanker travel and time to get production back online,” said Ryan McKay, senior commodity strategist at TD Securities. “We can end up losing another 1 billion barrels of supply during a recovery period.”
ING analysts noted that markets have already priced in much of the resolution. “Any confirmation of a deal that reopens the strait means that further downside is likely limited,” they wrote, but added that inventories are more depleted now than before the conflict began.
Government statistics published this week revealed crude petroleum reserves at the Cushing, Oklahoma distribution center decreased for a fifth straight week to 23 million barrels, nearing the approximately 20-million-barrel threshold considered minimum operational capacity. Distillate reserves reached their most diminished position in over twenty years.
Significant negotiation obstacles remain unaddressed. These encompass Iran’s nuclear development program, jurisdictional authority over the strategic waterway, and potential sanctions elimination. Trump previously articulated that waterway reopening and Iranian surrender of weapons-grade enriched uranium constituted his prerequisites for any diplomatic settlement.
Wider macroeconomic factors are simultaneously suppressing demand projections. U.S. personal consumption expenditure inflation metrics exceeded forecasts, strengthening assessments that the Federal Reserve may maintain elevated interest rates for extended periods. Adjusted first-quarter GDP figures similarly indicated decelerating economic expansion.
