Oil prices climbed on Monday as shipping traffic through the Strait of Hormuz slowed significantly, reflecting renewed tensions between Washington and Tehran.
The disruption comes as the first meeting between U.S. and Iranian officials under an interim peace deal got off to a bumpy start, raising immediate concerns about the durability of the ceasefire.
Brent crude futures rose in the session, driven by fears that the re-closure of the waterway could disrupt global energy flows.
The Strait of Hormuz remains a vital artery for global oil trade, and any sustained reduction in transit capacity typically triggers a risk premium in energy markets.
Traders are closely monitoring whether the slowdown in shipping is a temporary tactical move or a sign of deeper diplomatic failure.
The development follows recent statements from U.S. President Donald Trump, who indicated that the ceasefire with Iran is on life support after Tehran rejected a counterproposal to end the war.
