Oil prices climb more than 3% on fears of new US-Iran combat

[HOUSTON] Oil prices gained more than 3 per cent on Friday (May 15), after comments by US President Donald Trump and Iran’s foreign minister further dented hopes of a deal to end ship attacks and seizures around the Strait of Hormuz.

Brent crude futures settled at US$109.26 a barrel, up US$3.54, or 3.35 per cent. US West Texas Intermediate (WTI) futures finished at US$105.42 a barrel, up US$4.25, or 4.2 per cent. Over the week, Brent has climbed 7.84 per cent and WTI 10.48 per cent on uncertainty over the shaky ceasefire in the Iran war.

“The tone between the US and Iran has once again become significantly more confrontational. While the ceasefire holds, hopes for a swift reopening of the Strait of Hormuz have faded,” Commerzbank analysts said. Iran has “no trust” in the United States and is interested in negotiating only if Washington is serious, Foreign Minister Abbas Araqchi said on Friday, adding that Iran is prepared to go back to fighting but also prepared for diplomatic solutions.

Trump said that he is running out of patience with Iran and that he has agreed with Chinese President Xi Jinping that Iran cannot be allowed to have a nuclear weapon and must reopen the strait. About a fifth of the world’s oil and liquefied natural gas normally passes through the strait, which is the gateway to the Gulf and main export route for countries such as Saudi Arabia, Iraq and Qatar.

Xi did not comment on his discussions with Trump about Iran, though China’s foreign ministry issued a statement. “This conflict, which should never have happened, has no reason to continue,” the ministry said. Among the deals the market was looking for from the US-China summit, Trump said that China wants to buy oil from the United States. Trump also said he could lift sanctions on Chinese companies that buy Iranian oil.

“Market focus is back on the deadlock and a blockaded Strait of Hormuz, with a tail risk of renewed military escalation,” said Vandana Hari, founder of oil market analysis provider Vanda Insights.

Iran’s Revolutionary Guards said that 30 vessels had crossed the strait between Wednesday evening and Thursday, still far short of the 140 a day that was typical before the war, but a substantial increase, if confirmed.

“An increasing number of vessels are filtering through the strait … although currently this has a more tangible impact on sentiment than on the actual oil balance,” PVM analyst Tamas Varga said.

The strait’s closure comes at a time when reserves are running thin.

“The world has consumed its oil safety net at a historic rate,” Phil Flynn, senior analyst with Price Futures Group, said in a note. “While strategic releases and demand reduction have prevented immediate chaos, the margin for error is shrinking rapidly. A prolonged closure of the Strait of Hormuz points towards tighter physical markets, potential refined product shortages, and upward pressure on prices in the coming weeks and months.”

Shipping analytics firm Kpler said on Thursday that 10 ships had sailed through the strait in the past 24 hours, compared with the five to seven that have crossed daily in recent weeks. “Crude is trading higher on a combination of the Trump-Xi meeting doing little to bring us closer to a reopening of the Strait of Hormuz, and continued Ukrainian attacks on Russian refineries,” Saxo Bank analyst Ole Hansen said.
