Key Highlights
- Brent crude reached $90.75 per barrelāa five-week peakābefore settling near $88-$89 on Monday
- U.S. military operations against Iran entered their ninth consecutive day
- Only four vessels successfully navigated the Strait of Hormuz on Sunday, down from normal levels
- Two oil tankers were reportedly hit and disabled while attempting passage through the strategic waterway
- Market analysts from ANZ confirmed the expected shipping rebound has “effectively stalled”
Crude oil markets experienced significant volatility Monday as prices climbed to their highest point in more than five weeks, driven by intensifying military confrontations between the United States and Iran that have severely restricted oil tanker movement through the strategically vital Strait of Hormuz.
Brent crude touched $90.75 per barrel during intraday tradingāmarking its strongest performance in five weeksābefore retreating to approximately $88.26 following comments from an Iranian foreign ministry official suggesting Tehran might consider diplomatic engagement with Washington based on national security considerations.

Meanwhile, West Texas Intermediate declined 0.4% to settle at $82.18 per barrel after briefly trading above the $83 threshold earlier in the session.
Critical Shipping Route Experiences Dramatic Decline
The reduction in tanker traffic navigating the strait has been dramatic. Data from LSEG indicates only four vessels completed the passage on Sunday, representing a decline from the eight ships that transited the previous day.
Market strategists at ANZ reported that transit figures have collapsed to single-digit levels, noting that “the anticipated recovery in shipping has effectively stalled.”
Prior to the outbreak of hostilities with Iran in late February, approximately one-fifth of the world’s petroleum supplies passed through this critical chokepoint.
According to the Islamic Revolutionary Guard Corps, two petroleum tankers suffered explosions and became immobilized during transit attempts. Iranian authorities claimed the vessels had been advised by U.S. military personnel to utilize what Tehran characterized as a hazardous southern corridor.
Reuters reported it was unable to independently confirm these assertions.
American military forces have executed operations targeting Iranian positions for nine straight days. Iran has retaliated with counterstrikes against U.S. aircraft stationed at a Jordanian airfield, along with attacks on American military installations in Kuwait and Syria.
Bahrain authorities also confirmed warning sirens were activated Monday morning.
Supply Concerns Mount as Stockpiles Decline Globally
Giovanni Staunovo, an energy analyst at UBS, indicated the oil market is “again tightening,” as continuous attacks on vessels attempting to cross the strait have resulted in fewer tankers departing from Gulf regions.
ANZ market observers pointed out that despite increases in American crude production, these gains have failed to substantially alter the overall supply-demand equilibrium. Worldwide petroleum reserves continue their downward trajectory, maintaining pressure on both crude and refined product markets.
Brent benchmark prices recorded their strongest weekly performance since April last week, surging 15.9%. West Texas Intermediate jumped 15.5% during the corresponding timeframe, representing its most substantial weekly advance since early March.
Earlier during the conflict, Brent crude had surged past $110 per barrel before declining to roughly $70 following a ceasefire agreement signed in June. That peace accord has subsequently unraveled.
Persian Gulf nations did increase crude oil and condensate shipments in early July to their most robust levels since hostilities commenced. Nevertheless, movement through the Strait of Hormuz is decelerating once more as military operations intensify.
Tehran has also reportedly urged Houthi forces to shut down the Red Sea shipping corridor should American forces target Iranian electrical infrastructure, creating the possibility of additional supply chain interruptions.
