Crude benchmarks fell on Tuesday as geopolitical risk premiums eased after US President Donald Trump announced a suspension of a scheduled military attack on Iran.
Brent crude futures fell 1.5% to $110.42 per barrel, while Murban oil futures were down 1.5% to $106.62/bbl.
Analysts noted that the sudden downward shift in market momentum was directly triggered by a Truth Social post from Trump.
"No ships have reportedly left Iran's main export terminal during the past 10 days, potentially increasing the prospects for a deal," Saxo Bank analysts said.
Meanwhile, the US extended a key sanctions waiver that expired over the weekend, authorizing the sale of stranded Russian oil currently floating at sea for an additional 30 days.
The emergency extension permits these sales until June 17. This regulatory extension will provide substantial relief to Asian refining hubs, which carry the highest structural exposure to the ongoing shipping blockade.
However, the fundamental physical landscape remains severely constrained.
Transit through the critical Strait of Hormuz, the choke point for roughly one-fifth of global oil supply, continues to operate at only a small fraction of its pre-war baseline.
The physical toll of these prolonged disruptions is already manifesting heavily in Asian downstream processing volumes.
Fresh macroeconomic data out of China underscores a sharp contraction in the domestic oil sector.
According to ING analysts, Chinese refineries processed 13.35 million barrels per day of crude oil in April.
This represents a 5.8% year-on-year decline and marks the lowest crude throughput level for the world's largest oil importer since August 2024, confirming that supply-driven bottlenecks and high import costs are actively curbing global demand, ING added.
