London - Brent crude edged down on Wednesday as the six-day rally prompted some investors to lock in profits and Iran’s threat to halt oil shipments via the Strait of Hormuz was seen by the oil market as no more than rhetoric.
Brent fell 85 cents to $108.45 barrel by 09:34 GMT, after climbing more than a dollar in the previous session. Prices have surged over 5% since December 16. US crude turned negative, trading 40c lower at $100.94 by the same time.
Iran’s first vice-president warned on Tuesday that the flow of oil through the Strait of Hormuz would be stopped if foreign sanctions were imposed on Iran’s crude exports over its nuclear ambitions.
The remarks coincided with a 10-day Iranian naval exercise in the strait and nearby waters, a show of military force that began on Saturday.
The US state department said it saw “an element of bluster” in the threat.
“The threat by Iran to close the Strait of Hormuz supported the oil market yesterday, but the effect is fading today as it will probably be empty threats as they cannot stop the flow for a longer period due to the amount of US hardware in the area,” said Thorbjoern bak Jensen, oil analyst with Global Risk Management.
Still, any fall in oil prices may be limited for the long term by the tension over Iran.
“The issues are not going to be resolved quickly as to how supplies are going to be managed if we impose sanctions on Iran,” Greg Smith, executive director of Global Commodities.
“I’m a long-term bull and what we are seeing is justification as to why you want to be in for the long term.”
Most of the crude exported from Saudi Arabia, Iran, the United Arab Emirates, Kuwait and Iraq - together with nearly all the liquefied natural gas from lead exporter Qatar - must slip through the Strait of Hormuz, a 6.4 km-wide shipping channel between Oman and Iran.
About a third of all seaborne oil was shipped through the strait in 2009, according to the US Energy Information Administration, and US warships patrol the area to ensure safe passage.
Top oil exporter Saudi Arabia and other Gulf Opec states stood ready to replace Iranian oil if further sanctions halted Iranian crude exports, industry sources said.
