Global oil markets surged on Thursday following threats from U.S. President Donald Trump to impose secondary sanctions on any country purchasing crude or petrochemical products from Iran.

Why it matters:

Trump’s renewed hardline stance toward Tehran—issued just as U.S.-Iran nuclear talks stalled—jolted oil traders and triggered a nearly 2% rise in crude prices. The move could further destabilize global energy markets already facing uncertainty from OPEC+ supply decisions and weakening economic signals from the U.S.

 

The big picture:

Trump warned that “all oil or petrochemical purchases from Iran must stop,” vowing immediate sanctions against violators.

The threats followed delays in U.S.-Iran talks, originally scheduled for May 2, which were postponed at Oman’s request.

Iranian officials, including Foreign Ministry spokesperson Esmail Baghaei, confirmed that a new date would be announced later.

 

Key points:

  • Price movement:
  • Brent crude rose $1.07 (+1.8%) to $62.13 per barrel.
  • West Texas Intermediate (WTI) climbed $1.03 (+1.8%) to $59.24 per barrel.
  • Market reaction:
  • OPEC+ members are debating whether to increase output again in June.

 

Go deeper:

As Trump’s threat caused a short-term oil price bump, data released Wednesday showed the U.S. economy contracted in Q1—the first negative growth in over a year—partly due to uncertainty caused by Trump-era tariffs and import surges. According to a Reuters poll, those tariffs may help push the global economy toward recession this year. With OPEC+ members divided and Washington’s Iran policy again in flux, volatility in oil markets is poised to continue.
