What happened with ASX 200 energy shares last week?
The Brent Crude oil price shot 5.5% higher to US$107 per barrel last week as negotiations to end the Iran war stalled.
The Strait of Hormuz, through which about 20% of the world's gas and oil supply is shipped, remained effectively shut down.
On Friday, Trading Economics analysts said:
The key shipping route remains under a dual blockade that has emerged as a central obstacle in negotiations, with President Donald Trump saying the current ceasefire was on "massive life support" after dismissing Tehran's latest response to his peace proposal.
Meanwhile, the IEA reported that crude and fuel flows through the Strait of Hormuz dropped by around 4 million barrels per day in March and April, warning that the global oil market could stay materially undersupplied through October even if the conflict is resolved next month.
Meanwhile on the market, the Woodside Energy Group Ltd (ASX: WDS) share price rose 3.99% to close at $31.25 on Friday.
