Crude oil valuations surged more than 5% this Wednesday following President Donald Trump’s declaration that the understanding reached with Iran to conclude Gulf hostilities was “over.”

During his remarks at a NATO gathering in Turkey, Trump criticized Tehran for engaging in duplicitous behavior. “As far as I’m concerned, it’s over,” he declared, characterizing negotiations with Iran as “just a waste of time.”
These statements sent shockwaves through financial markets already experiencing heightened anxiety following recent military confrontations between American and Iranian forces.
Brent crude futures surged 5.5% to reach $78.24 per barrel. U.S. West Texas Intermediate climbed roughly 3% to settle at $72.49 per barrel. This represents Brent’s most substantial single-session gain since the end of May.
Persian Gulf Military Confrontations Intensify
Iran’s Islamic Revolutionary Guards Corps announced it had targeted 85 American military facilities across Kuwait and Bahrain, while also destroying an American MQ-9 reconnaissance drone.
The Pentagon characterized its military operations as retaliatory measures in response to Iranian aggression against commercial shipping in the Strait of Hormuz. U.S. Central Command confirmed striking over 80 Iranian targets and approximately 60 Iranian small watercraft in and around the strategic waterway.
Tehran has declined to accept responsibility for Tuesday’s assaults on commercial vessels near Oman’s coastline, which affected a Saudi petroleum tanker and a Qatari ship transporting liquefied natural gas.
Discussions toward a lasting peace settlement are now reportedly on hold during funeral proceedings for former Iranian Supreme Leader Ayatollah Ali Khamenei, who perished during a combined U.S.-Israeli military operation against Iran in late February.
The Strait of Hormuz serves as the transit point for approximately one-fifth of global oil and LNG shipments. OCBC analysts suggested that while a complete return to armed conflict seems improbable given domestic political considerations ahead of November midterm elections, they emphasized that “no clear path to fully securing the Strait of Hormuz” currently exists.
The United States additionally withdrew a sanctions exemption that had previously enabled Iran to market oil on international markets, a decision that may further constrict global crude availability in coming weeks.
Equities Decline, Government Debt Yields Climb
The oil surge severely impacted worldwide financial markets. European equities dropped 1.6%, tracking toward the STOXX 600’s steepest single-day decline since mid-March. U.S. stock index futures descended between 0.8% and 1.2%.
The VIX volatility gauge jumped nearly 13%, marking its largest one-day increase in more than a month.
U.S. 10-year Treasury yields advanced to a one-month peak of 4.56%. German and Italian government bond yields similarly reached one-month highs.
Recently published data revealed U.S. Strategic Petroleum Reserve inventories fell to their lowest point since 1983, increasing market vulnerability to supply interruptions.
Semiconductor and artificial intelligence equities were experiencing downward pressure even before Trump’s remarks, as market participants reassessed elevated valuations. Samsung declined for a consecutive session despite announcing a 19-fold profit increase. Apprehension is mounting that memory chip consumption may decelerate during the year’s latter half.
The dollar strengthened throughout the trading session, lifting the euro marginally above $1.14. The Federal Reserve’s June policy meeting minutes are scheduled for release later Wednesday.
