Mubasher: Oil futures ends Friday in stability, record losses in a week, as many factors threaten prices.  

March Nymex WTI inched up $0.08, or 0.2%, to close at $52.74 per barrel, declining 4.6% for the week.

Igor Sechin, head of Rosneft, said in a letter to the Russian president Vladimir Putin that the oil-output-cut deal between members of OPEC and some independent producers was a threat to Russia.

Reuters reported on Friday that the US president Donald Trump might support a bill targeting the Organization of the Petroleum Exporting Countries (OPEC).
