Brent crude fell 1.87% to $92.63 on Monday, giving back part of last week's rally as traders assessed Washington's escalating pressure campaign on Iran.
West Texas Intermediate slid 1.97% to $85.35. The selling ran across the energy complex, with natural gas, gasoline, and heating oil each losing between 1.68% and 1.88%.

Both benchmarks gained more than 5% last week on the escalating rhetoric. President Donald Trump on August 19 announced what he described as the “most crushing economic operation ever taken against any country.”
Trump said the measures would target Iran’s economy and isolate the country internationally, while warning that nations providing financial, commercial, or other support to Tehran could face severe economic consequences.
“This will be an ECONOMIC D-DAY, and we need all of our Allies to stand with the United States of America to isolate, and defeat, the Iran threat,” he said.
Bessent made the same case in a Financial Times opinion piece published Sunday, writing that an economic D-Day begins at dawn.

President Trump has dismantled Iran’s military capabilities, destroyed nearly 100 percent of its military factories, and buried its nuclear program.

We are now entering the endgame. At dawn begins an economic D-Day — the single greatest financial offensive ever marshaled against…
Narrower measures are already in force. The Treasury's Office of Foreign Assets Control (OFAC) froze more than $130 million in crypto tied to Iran in July, then hit a Hormuz shipping toll scheme weeks later.
Monday's reversal, therefore, points to supply news rather than the policy outlook. BeInCrypto reported that ship transits through the Strait of Hormuz climbed from 39 to 192 over two weeks, a 392% rise.
Traffic still sits roughly 90% below pre-war levels, when about 20.9 million barrels a day moved through the waterway, according to EIA figures.
Many captains switch off transponders in a war zone. Part of the increase, therefore, reflects ships restoring signals rather than fresh cargo.
Iran’s Revolutionary Guard Calls the Campaign an Admission of Defeat
Iran dismissed the campaign. Hossein Mohebbi, spokesman for the Islamic Revolutionary Guard Corps, called it an admission of military defeat, TASS reported.
"[US President Donald] Trump’s executive order on the launch of the toughest economic warfare against Iran mounts to a tacit acknowledgement of Washington’s defeat on the military front," he said.
Mohsen Rezaei, secretary of Iran's Supreme National Security Council, threatened to halt oil flows through the strait entirely.
Markets have also grown less responsive to the rhetoric. Axios tracked 269 Trump posts mentioning Iran or Hormuz since February and found the price impact fading over time.
Scope will decide whether Monday's decline holds. Iranian exports are already constrained by a naval blockade, so fresh measures may add little to the supply picture. The unresolved question is China, which buys more than 80% of Iran's shipped oil according to Kpler.
