Crude Oil Jumps After Trump’s ‘Crushing’ Economic Threat to Iran

Oil prices climbed sharply on Thursday after US President Donald Trump threatened “economic warfare” against Iran. Brent crude futures rose more than 2%, touching almost $94 a barrel, the highest level since late July. US benchmark WTI futures gained around 2.5%, trading near $86 a barrel. The jump in oil prices Iran markets came hours after Trump posted a warning on Truth Social about a major economic crackdown on Tehran.

What Trump said

Trump said Iran had failed to take an offer to end the war with the United States. He announced what he called the “most crushing economic operation ever taken against any country.” He described the plan as “Economic Warfare and Isolation on an unprecedented scale.”

Trump also warned that any country helping Iran would face heavy consequences. He wrote that nations allowing their banks, businesses, airports, or government bodies to support Iran would suffer serious economic fallout. He called on US allies to join the effort, calling it an “ECONOMIC D-DAY.”

The president listed specific targets for the crackdown. These include:

• Oil smuggling networks
• Currency swap lines
• Cash transfers
• Exchange houses
• Ship registries
• Front companies linked to Iran

Trump did not share exact details on how the operation would work.

Background on the US-Iran conflict

Tensions between Washington and Tehran have grown since a 60-day ceasefire expired earlier this week. The two sides failed to reach a diplomatic breakthrough during that window. Fighting between the US, Israel, and Iran restarted weeks before the deadline, after months of on-and-off military action.

Iran has effectively closed the Strait of Hormuz since fighting began in February. The strait is a major route for global oil shipments, and its closure has disrupted supply chains worldwide. The United Arab Emirates recently said it was suspending trade with Tehran, adding pressure on Iran’s economy.

Iran’s economy has struggled through the conflict. Inflation has stayed near 65% over the past year, according to Iran’s central bank. Trump has said the country’s currency has become largely worthless and that Iran’s military infrastructure has suffered heavy damage.

Why oil prices are reacting

Brent crude has risen for five straight sessions, adding more than 5% over that period. Analysts say the market is responding to fears that economic and military pressure on Iran could further disrupt oil flows through the Gulf region. Some analysts noted that the price increase was relatively mild given the scale of Trump’s threats, suggesting markets may be waiting for more concrete details before reacting further.

The Trump administration has shifted its approach in recent weeks. Officials have moved from direct military action toward broader economic pressure, aiming to push Iran back to the negotiating table. The stated goals include ending the war, stopping Iran’s nuclear program, and reopening the Strait of Hormuz.
