[NEW YORK] Oil prices climbed more than 4 per cent to their highest in more than a month on Friday (Jul 17) after the US and Iran stepped up attacks across the Gulf, with shipping threatened by a potential Red Sea closure on top of the restricted traffic through the Strait of Hormuz.
Brent crude futures settled US$3.87, or 4.59 per cent, higher to US$88.10 a barrel, while US West Texas Intermediate futures rose US$3.54, or 4.48 per cent, at US$82.49. Both were at their highest since mid-June.
For the week, both benchmarks gained about 16 per cent, with Brent on track for a third consecutive weekly gain and WTI set for its second.
The two foes expanded fighting on Friday, with the US striking bridges and an airport in Iran and Teheran hitting a power and desalination plant in Kuwait. Iran said it launched more strikes on US facilities in the Middle East, including the first direct attack in Syria, after a sixth straight night of US strikes on Iranian military facilities.
“The market is reacting to the increasing hostilities between Iran and the United States that have culminated this week with nightly attacks on Iranian infrastructure and retaliation by Iran on its neighbors’ infrastructure,” said Andrew Lipow, president of Lipow Oil Associates. “If more tankers come under fire and become damaged, we’re going to see oil prices continue to move up as shipowners simply refuse to enter the Persian Gulf.”
The collapsed truce between the US and Iran has resulted in a sharp decline in oil flows in the strait as Iran targets vessels transiting through it. Before the Iran war, about 20 per cent of global oil supplies flowed through the waterway. Iran has pressed the Houthis to close the Red Sea route if the US attacks Iran’s power infrastructure.
“Given that so much of Saudi Arabia’s exports have been redirected to the port of Yanbu via the East-West Pipeline to avoid Hormuz, any such development is a threat indeed,” Tamas Varga, analyst at PVM Oil Associates, wrote in a note.
Saudi Arabia has diverted more than 70 per cent of its normal daily crude exports to the Red Sea port of Yanbu since the beginning of the war. Shipments from Yanbu averaged 4 million barrels per day in recent weeks, up from around 973,000 bpd in the same period last year.
Qatar’s defence ministry said its armed forces thwarted an Iranian missile attack early on Friday and the interior ministry said a child was wounded by shrapnel resulting from interception operations.
