Crude oil prices ticked higher on Tuesday, supported by escalating US-Iran tensions and constrained maritime trade through key Middle East chokepoints.
Front-month Murban crude futures edged up 0.5% to $98.20 per barrel following a rally on Monday, while Brent futures gained 0.4% to $91.22/bbl.
"Oil remains supported near $90/bbl by Middle East tensions and attacks on vessels in the Strait of Hormuz," ING analysts said.
Commercial vessel traffic through the Strait of Hormuz slowed to a trickle last week as persistent regional security threats continued to deter operators, while traffic via the Bab el-Mandeb increased despite threats, according to shipping data released Monday.
The latest data from MarineTraffic show that a total of 95 vessels crossed the Strait of Hormuz last week, down 19.5% from 118 during Aug. 2-9.
Iranian Foreign Ministry spokesman Esmail Baqaei reportedly ruled out talks to extend a June memorandum of understanding, alleging that the US violated the agreement from the outset, while an Iranian official warned of potential regional escalation.
"Crude oil prices rose on fading hopes of a peace deal between the US and Iran. Talks appear to be at a standstill, as the 60-day truce expired on Monday," ANZ analysts noted.
Crude prices are likely to test higher levels in the near term as renewed US-Iran tensions and constrained shipping via the Strait of Hormuz offset bearish signals from rising US crude inventories and strong production, EBW Analytics Group strategists said in a note Monday.
The US Department of Energy's Strategic Petroleum Reserve data released Monday showed SPR inventory levels as of Aug. 14 stood at 293.4 million barrels.
