Oil surges 6%, stocks tumble after Trump says Iran ceasefire is ‘over’

“To me, I think it’s over,” Trump said on the sidelines of the NATO summit in Ankara, Turkey. “I don’t want to deal with them anymore.”

“As far as I’m concerned, it’s over,” the president continued. He said that negotiations could continue but that he considers them a “waste of time.”

U.S. crude oil sharply jumped more than 6.5% to $75 per barrel, its largest one-day move up since the beginning of June. International oil benchmark Brent rose 6.2% to almost $79 per barrel.

Those big jumps came one day after jitters returned to oil markets, sending U.S. crude oil prices from about $69 to more than $72.

The rapid rise in oil prices also underscores how fragile falling gas prices are. Over recent weeks, falling oil prices have translated into a national average gas price that has fallen from as high as $4.56 per gallon in May to $3.79 as of Wednesday morning. However, the drop has effectively come to a halt and the national average remained flat over the last two days, according to AAA data tracked by NBC News .

Meanwhile, U.S. stock futures sharply dropped.

S&P 500 futures pointed to a drop of more than 1% at Wednesday’s opening bell, Nasdaq 100 futures dropped 1.5% and Dow Industrial Average futures slid more than 710 points.

The drop in stock futures compounded what was already a chip and tech-stock fueled sell off that started on Tuesday.

Russell 2000 futures, which track small and mid-cap companies, tumbled 1.6%.

Heating oil prices, a proxy for jet fuel, climbed 2%.

In turn, airline stocks were some of the hardest hit shares in pre-market trading. Delta Airlines and Southwest Airlines tumbled 3%, while United Airlines fell 3.5%. Other travel stocks, such as Carnival and Royal Caribbean Cruises fell by almost 4%.

Global stocks also sold off, with flagship stock indexes in Spain, Germany and France plunging 2%. Benchmark indexes in Italy and the U.K. fell by around 1.5%.

On Tuesday, the U.S. said that Iran struck three commercial vessels near the Strait of Hormuz. Tehran has not claimed responsibility for the attacks.

Later in the day, the U.S. Treasury revoked a sanctions waiver that allowed Iranian oil to be sold into the global market and U.S. Central Command launched “a series of powerful strikes against Iran” in retaliation for the vessel attacks.

“Renewed tensions in the Middle East have interrupted what had become an increasingly complacent market narrative, prompting investors to reassess geopolitical risks after several weeks of pricing in a smooth path toward de-escalation,” said Capital.com market analyst Daniela Hathorn in a Wednesday morning note.

“The latest attacks have lifted oil prices, weighed on equity markets and reminded investors that while a ceasefire remains in place, a lasting agreement between the US and Iran is far from guaranteed,” she added.

After the U.S. and Iran signed a memorandum of understanding in mid-June, U.S. oil prices stabilized around $69-$70 per barrel and remained there for the better part of three weeks.
