Brent crude is down 3.6% at $94.00 a barrel as of 07:26 US Eastern (12:26 GMT) on Monday 9 November, according to Oilprice.com. The US benchmark, WTI, is down 3% at $88.09.
That is lower than the $96.38 a barrel CBS News reported in an entry updated at 11:39 GMT. Monday's fall has therefore deepened through the morning.
Oilprice.com links the latest drop to Qatar's prime minister taking an Iranian proposal on the Strait of Hormuz to the White House.
The site also says last week's 16% slide in Brent was its steepest weekly fall since the start of the Covid-19 pandemic. That is consistent with earlier reporting, which put last week's fall at more than 16%. The comparison with the pandemic has not been independently checked.
