Oil prices settled higher by more than 1 per cent on Monday after attacks by the United States and Iran underscored the fragility of their interim peace deal.
Brent crude futures gained $1.16 or 1.61 per cent to sell at $73.15 a barrel, while the US West Texas Intermediate (WTI) crude appreciated by $1.52 or 2.2 per cent to $70.75 per barrel.
The latest price movement appears to suggest that the market is concerned about a reduction in tanker traffic through the Strait of Hormuz following attacks on two commercial vessels on Thursday and Friday last week, and a further flare-up over the weekend.
The Thursday attack on the container ship Ever Lovely prompted some shipowners to pull back and wait for additional information about how safe transiting the Strait is. The US military on Friday carried out strikes on Iran in response to the attack on the vessel.
On Saturday, an Iranian attack on a Panama-flagged oil tanker, Kiku, while it was transiting the Strait of Hormuz, prompted additional strikes by the U.S. forces.
After the flare-up this weekend, the US and Iran appear to have agreed to cease attacks ahead of tentatively planned new talks this week.
Iranian and US technical teams working on the implementation of an interim peace deal are expected to meet in Doha in the coming days, even after both sides carried out strikes over the weekend that threatened to derail the accord.
Iranian Deputy Foreign Minister Kazem Gharibabadi said Iranian and Omani experts will start talks on redefining transit paths through the Strait of Hormuz in the coming days, adding that his country will try to obstruct vessels outside of defined paths.
Analysts cautioned that traffic through the strait is far from being fully recovered, helping keep prices somewhat elevated as outbound Persian Gulf crude exports are quickly rebounding to at least 75 per cent of pre-war levels.
Middle East producers are pushing ahead with loading oil and Liquefied Natural Gas (LNG) despite fresh ship attacks in the Strait of Hormuz and renewed strikes between the US and Iran in recent days.
Saudi oil giant Aramco resumed crude oil loadings on Friday at its Ras Tanura terminal, west of the Strait of Hormuz, after they were halted for nearly four months. Loadings continued even after a helicopter belonging to the company crashed on Sunday at Ras Tanura, killing 14 nationals. The cause of the crash was unknown.
