Oil prices experienced dramatic fluctuations Monday as market participants analyzed competing signals from escalating military threats and emerging diplomatic possibilities.
Brent crude pushed above the $110 threshold during trading before retreating. By Asian mid-morning sessions, the benchmark held near $109.80, registering a 0.7% gain. West Texas Intermediate remained relatively stable at $111.62.

The price volatility demonstrates how closely energy markets monitor each development in the ongoing U.S.-Iran confrontation, which commenced following combined American and Israeli military operations against Iranian targets on February 28.
Prior to hostilities, Brent traded around the $70 mark. The benchmark crossed triple digits last week following Trump’s warning about devastating military action against Tehran.
Sunday brought an inflammatory Truth Social post from Trump, warning that American forces would target critical Iranian infrastructure including power generation facilities and transportation bridges unless the Strait of Hormuz reopened by Tuesday evening Eastern time.
Trump declared: “Tuesday will be Power Plant Day, and Bridge Day… Open the Fuckin’ Strait, you crazy bastards, or you’ll be living in Hell.”
He later confirmed the specific timing: “Tuesday, 8:00 P.M. Eastern Time.”

During a Fox News appearance, Trump suggested diplomatic resolution remained possible Monday. He mentioned the option of “blowing everything up and taking over the oil” should negotiations collapse.
Iranian officials dismissed the ultimatum. Senior military commander General Ali Abdollahi Aliabadi characterized the deadline as “helpless, nervous, unbalanced and stupid” while warning that “the gates of hell will open” for Trump.
Diplomatic Framework Takes Shape
Axios reported that American, Iranian, and regional intermediaries are examining a potential 45-day cessation of hostilities that could evolve into permanent peace. Reuters confirmed that both governments received a preliminary framework potentially taking effect Monday.
White House officials had yet to respond to media inquiries. BBC News noted it could not independently confirm the Axios reporting.
Iranian military operations continued throughout the weekend, with Tehran claiming responsibility for attacks on energy facilities across Kuwait, Bahrain, and the United Arab Emirates. Monday brought fresh IRGC warnings about intensifying strikes against American economic targets should attacks on Iranian civilian infrastructure persist.
OPEC+ Production Increase Faces Reality Check
OPEC+ members reached agreement Sunday to expand crude production by 206,000 barrels daily beginning in May. Industry observers note the increase exists primarily on paper. Multiple significant members lack capacity to boost output due to conflict-related disruptions.
The Strait of Hormuz, typically carrying approximately one-fifth of global energy shipments, has remained closed for weeks. The blockade has elevated energy costs worldwide and sparked inflation worries across nations reliant on Middle Eastern petroleum.
Wood Mackenzie consultant Sushant Gupta predicted sustained price volatility, with each conflict development triggering market reactions.
