President of the United States Donald Trump has threatened Iran with a potentially much larger military attack following strikes by Iran-aligned Houthi forces on Saudi oil tankers in the Red Sea, escalating fears that the widening Middle East conflict could further disrupt global energy supplies and international shipping.
Trump said Iran and its Houthi allies would face “major military punishment” following missile and drone attacks on two Saudi oil tankers, as Washington increasingly holds Tehran responsible for the actions of the Yemeni group.
The president indicated that he was considering an attack larger than previous US operations against Iran.
The warning came after the Houthis said they had attacked two Saudi tankers as part of what they described as a naval blockade of Saudi Arabia. The vessels were identified by Reuters as the Encelia and Layla.
The attacks have dramatically increased concerns over the security of the Bab el-Mandeb Strait, the narrow passage connecting the Red Sea with the Gulf of Aden and one of the world's most important maritime trade routes.
A Second Oil Chokepoint
The significance for energy markets extends well beyond the two vessels attacked.
Iran's restrictions on shipping through the Strait of Hormuz have already disrupted tanker movements from the Persian Gulf. Houthi attacks around Bab el-Mandeb now threaten another major route used to carry Middle Eastern crude towards Europe and Asia.
Together, disruption around Hormuz and Bab el-Mandeb could affect routes normally handling more than a quarter of global oil and gas shipments.
Tankers avoiding the Red Sea must instead sail around the Cape of Good Hope, adding considerable time, fuel consumption and freight costs to voyages.
Markets React Immediately.
Brent crude surged around 7% on Thursday to settle at US$100.69 a barrel, crossing the psychologically important US$100 threshold for the first time since May. The rally represented a dramatic reversal from early July, when Brent had fallen to around US$72 amid hopes of progress in US-Iran negotiations.
Prices eased on today, with Brent trading around US$99, but the international benchmark remained on course for a weekly gain of roughly 12%.
Wall Street Feels the Shock
The oil spike added another layer of anxiety to financial markets already unsettled by technology-sector earnings.
Wall Street fell sharply on Thursday, with the Nasdaq losing more than 2% and the S&P 500 dropping more than 1%. Investors were simultaneously digesting disappointing results and heavy artificial-intelligence spending by major technology companies, including Alphabet and Tesla. Tesla shares fell around 14%, while Alphabet dropped about 7%.
The return of US$100 oil has also revived fears that energy costs could feed another wave of global inflation.
Higher fuel prices increase transportation, aviation, manufacturing and logistics costs, while also reducing household spending power.
Persistently high crude prices could therefore complicate efforts by central banks to lower interest rates. Bond markets have already begun reflecting those concerns, with longer-term yields rising as investors reassess the inflation outlook.
Shipping Industry Faces Another Escalation
For global shipping, the Houthi attacks represent an especially worrying development.
The Red Sea crisis had already forced many container lines to divert vessels around southern Africa. A sustained campaign against Saudi oil shipments could now produce similar changes in tanker deployment, increasing voyage distances and tightening available vessel capacity.
The greater danger is that the Middle East's two critical maritime gateways could face disruption simultaneously.
That prospect turns the conflict from primarily a regional military confrontation into a potentially systemic threat to global trade. Energy prices, tanker freight rates, marine insurance premiums and shipping schedules could all face further pressure if attacks intensify.
Trump's latest threat therefore carries substantial economic consequences. A major new US strike against Iran could provoke further Iranian retaliation - either directly against American and regional targets or indirectly through allied groups such as the Houthis.
With Brent back around US$100 and investors already retreating from risk assets, markets are increasingly confronting the possibility that the latest escalation may not remain confined to the battlefield.
