Brent oil prices plummeted this week to five-year lows underneath $60 per barrel as markets were rocked by shrinking Chinese manufacturing output, economic turmoil in Russia and ample crude supplies.
Oil has now halved in value since June, due also to the stronger dollar and weak demand as the global economy struggles.
Investors closely watched the situation in crude producer Russia, as the ruble crashed to a series of record lows, despite a drastic interest rate hike.
"The combined effects of slumping oil, the Russian Central Bank`s interest rate hike and falling output from China have all come together to deliver a triple blow to the markets," said ETX Capital analyst Daniel Sugarman.
"Lower output from China means less of a need for oil, while as a primary oil producer Russia really feels the pain of lower oil prices, compounded by the sanctions imposed earlier this year."
Many commodities fell in line with oil, but sentiment was subdued on Friday with many traders away for an extended Christmas and New Year holiday.
OIL: Brent prices plunged late Tuesday to $58.50 -- a low last seen on May 26, 2009 -- and New York crude hit a similar low at $53.60 after OPEC signalled it has no plans to intervene to shore up plunging prices.
Brent had already breached the psychological $60 barrier earlier Tuesday as weak Chinese manufacturing data stoked global demand concerns.
The market however rebounded on Friday, in line with gains on global stock markets, as investors snapped up bargain crude.
"Until the issue of low global demand and oversupply is resolved, we will continue to see this type of market volatility as investors test the waters," Phillip Futures analyst Daniel Ang told AFP.
"There are two camps in the market at the moment. Some who believe prices can fall further, and others who are betting that it should be above $60."
The Organization of the Petroleum Exporting Countries (OPEC), the oil producers group that supplies about a third of global oil, has so far declined to cut output to curb the price plunge.
Top OPEC producer Saudi Arabia said Thursday that competitive pressures prevent it from reducing output, and the kingdom can weather falling prices.
"It is difficult, or even impossible, for Saudi Arabia or OPEC to undertake any measure that would lead to a reduction in (their) share of the market and an increase in that of others" who do not belong to the cartel, said Oil Minister Ali al-Naimi.
The latest selloffs came after OPEC opted last month to maintain its collective output ceiling at 30 million barrels per day, where it has stood for three years.
"At OPEC`s meeting in November, we took two decisions," added Kuwaiti oil minister Ali al-Omair on Tuesday.
"The first was to keep the production ceiling unchanged and the second to hold the next meeting in June. So far, nothing has changed and there are no calls for holding an emergency meeting."

The gold price was "hindered by the Fed statement confirming small steps towards rising rates which has kept the dollar strong and made the metal more expensive to buy," said Accendo Markets analysts.

BASE METALS: Base or industrial metals dived on fresh evidence of economic troubles in key consumer China.
China`s manufacturing activity worsened in December with HSBC`s purchasing managers` index (PMI) hitting a seven-month low at 49.5 percent, below the break-even point dividing expansion and contraction.
That signalled fresh weakness in the world`s second-largest economy and major consumer of oil and base metals, according to analysts.
"Since the beginning of the week, the majority of prices on the London Metal Exchange (LME) have found themselves under pressure," said Commerzbank analysts.
"HSBC`s disappointing flash PMI for Chinese industry appears to be having a greater impact than initially assumed."

COCOA: Prices gained ground, having won strength in recent months on fears that the Ebola outbreak would impact output from key producers Ghana and Ivory Coast.
"Cocoa is ... one of the few commodities likely to end 2014 in the black, its price having been driven up for a time by the Ebola epidemic in West Africa," noted Commerzbank analysts.
