Oil prices have fallen about one per cent and notched a weekly loss of over six per cent, as investors worried about oversupply after the United States said it will temporarily spare eight jurisdictions from Iran-related sanctions.
US Secretary of State Mike Pompeo announced the decision in a conference call. The waivers could allow top buyers to keep importing Iranian oil after economic penalties come back into effect on Monday.
Brent crude futures fell 6 cents to settle at $US72.83 a barrel.
US crude declined 55 cents to end the session at $US63.14 per barrel, a 0.86 per cent loss.
Both contracts have fallen more than 15 per cent from the near four-year highs touched in early October on worries the looming Iran sanctions could drain supply from global markets.
Pompeo did not name the jurisdictions, but said the European Union as a whole, which has 28 members, would not receive one.
India, Iraq and South Korea were on the list of waivers, said a source familiar with the matter who spoke on condition of anonymity.
Under US law, such exceptions can only be granted for up to 180 days.
Turkey has been told it will receive a waiver on US sanctions against Iranian oil sales, Turkish Energy Minister Fatih Donmez said.
Iran said on Friday that it had no concerns over the reimposition of sanctions.
On Twitter, in a message designed to emphasise his ‘maximum pressure’ policy toward Iran, US President Donald Trump included a photograph of himself modelled on a popular television show poster with the headline: ‘Sanctions are coming November 5.’
‘It seems as though all the worries about tightening supplies due to the loss of Iranian barrels in the market have dried up,’ said Gene McGillian, director of market research at Tradition Energy in Stamford, Connecticut.
‘On top of that, concerns regarding reduced global demand has also helped … the market continues to search for a bottom.’
Prices have been under pressure as world oil production has been rising significantly in the past two months.
Russian Energy Ministry data showed on Friday the country pumped 11.41 million barrels per day of crude in October, a 30-year high.
The US believes that global oil supplies will exceed demand next year making it easier for countries to cut Iranian oil imports to zero, a senior US official said on Friday.
The Organisation of the Petroleum Exporting Countries boosted oil production in October to 33.31 million bpd, up 390,000 bpd and the highest by OPEC since 2016.
The United States is challenging Russia for title of top producer, with US crude production now above 11 million bpd.
The US oil drilling rig count declined this week for the first time in four weeks, with drillers cutting one oil rig in the week to November 2, bringing the total count down to 874, General Electric Co’s Baker Hughes energy services firm said in a report on Friday.
Hedge funds and money managers cut their net long US crude futures and options positions in latest week to a fresh one-year low, according to data from the US Commodity Futures Trading Commission.
