Brent crude rose 1.2% to $106.64/barrel, peaking at $107.97, after media report of Iran's proposal to reopen Hormuz.
WTI increased 0.9% to $95.21/barrel amid limited oil flows through Hormuz and ongoing US‑Iran tensions.
Iran's proposal includes postponing nuclear discussions; US Treasury Secretary said waiver for Russian/Iranian oil purchases will not be renewed.
Iran's blockade since late February cut roughly 20% of global crude supply, keeping markets wary of supply disruptions.
