London (CNN) — Oil prices fell sharply Tuesday after US President Donald Trump said the war with Iran would be over “very soon,” though they remain volatile and well above their levels before the conflict started.
Also on Tuesday, the world’s biggest oil exporter, Saudi Aramco, warned of the war’s potentially “catastrophic consequences” for oil markets if flows don’t resume through the vital Strait of Hormuz.
Brent crude, the global oil benchmark, slid 7% to trade at $91.8 a barrel. WTI, the US benchmark, fell more than 6% to around $88.6 a barrel. Those prices compare with around $73 and $67 respectively before the United States and Israel launched strikes on Iran on February 28.
Early on Monday, both oil prices surged above $100 a barrel, crossing that mark for the first time since Russia’s 2022 invasion of Ukraine. Brent neared $120 a barrel at one point Monday.
The sharp reversal in prices came after Trump’s comments during a phone interview with CBS appeared to calm markets. “I think the war is very complete, pretty much,” he told the broadcaster.
Although he later appeared to contradict those remarks, investors were also hopeful about other options now on the table to increase global oil supply and resume tanker transits through the Strait of Hormuz – the main channel for transporting the Middle East’s copious oil output to the rest of the world.
For example, the White House has said it will provide insurance and secure naval escorts for ships transiting the strait, although a clear plan hasn’t yet emerged. On Tuesday, Trump vowed to hit Iran “TWENTY TIMES HARDER” if it “does anything” to stop the flow of oil through the strait, according to a Truth Social post.
Meanwhile, the Group of Seven major developed economies, or G7, said Monday that they stood ready to support global energy markets through the release of oil reserves if necessary.
These reserves could be significant – around 1 billion barrels, excluding China and Canada, according to one estimate – and would help put a cap on oil prices. “Strategic reserves would help if the war is to be measured in weeks, which remains our base case,” said Mohit Kumar, an analyst at US investment bank Jefferies. “But if it’s an extended war lasting months, strategic reserves alone would not be sufficient,” he added.
Indeed, the outlook for prices remains highly uncertain. On Tuesday, Saudi Aramco, the world’s top oil exporter, warned of dire consequences should the war continue to disrupt oil flows through the Strait of Hormuz.
“There would be catastrophic consequences for the world’s oil markets, and the longer the disruption goes on… the more drastic the consequences for the global economy,” Aramco CEO Amin Nasser told reporters on an earnings call, according to Reuters.
“While we have faced disruptions in the past, this one by far is the biggest crisis the region’s oil and gas industry has faced,”
