Oil prices extended the gloom on Monday after a Saudi-Russian price war and an equities meltdown sparked by the coronavirus pandemic saw their biggest weekly losses in more than a decade.
US benchmark West Texas Intermediate (WTI) briefly fell below US$30 a barrel, or 5.5 percent, in morning Asian trade before regaining its footing.
It was trading at US$31.13 a barrel at around 0530 GMT, down nearly two percent from Friday's close.
The Brent global benchmark was down 3.28 percent at US$32.74 a barrel.
Last week's price war began after Saudi Arabia and other members of an informal alliance of major crude producers led by the OPEC oil cartel pushed for an output cut to combat the impact of the virus outbreak.
But alliance partner and non-OPEC member Russia, the world's second-biggest oil producer, refused - prompting Riyadh to drive through massive price cuts and pledge to boost production.
The COVID-19 outbreak added to downward pressure as it throttled global equities, with growing concerns over a potential worldwide recession and escalating travel restrictions prompting a crash in demand forecasts.
Prices made a feeble rally late last week after US President Donald Trump announced US$50 billion in Federal spending to stem the damage from the coronavirus and plans to buy "large quantities of crude oil" to top up strategic reserves.
But both benchmarks still fell by around 25 percent in the biggest weekly drop since the global financial crisis in 2008, and more losses are expected.
"Rallies will likely continue to fade so long as the market continues to weigh the double-whammy of the COVID-19... and the massive jump in supply," said Stephen Innes, global chief markets strategist at AxiCorp.
"The rare combination of severe shocks to both supply and demand has caused the crude market to collapse as producers... steel themselves for an unexpected glut of oil in coming weeks," added Sukrit Vijayakar of Trifecta Consultants. - AFP
