LONDON, March 5 (Reuters) - World stocks and oil fell on Thursday after General Motors <GM.N> warned of possible bankruptcy, while European currencies and yields stayed weak after the euro zone and UK central banks cut interest rates.
U.S. automaker GM said it had substantial doubts about its ability to continue as a going concern if it fails to stem its losses and generate cash, and it may be forced to file for bankruptcy. [
]The euro and sterling were down about 0.7 percent against the dollar after the European Central Bank and Bank of England cut interest rates to all-time lows.
The BoE, after cutting the cost of borrowing to 0.5 percent, said it would buy assets worth 75 billion pounds in order to expand money supply. Euro zone rates now stand at 1.5 percent.
"The Bank of England has been cutting rates aggressively now for several months, but it hasn't sparked life into the economy so it's high time for new medicine, namely quantitative easing," said Manoj Ladwa, senior trader at ETX Capital.
"But it will only work if banks loosen their lending criteria and a measure of business confidence returns. The policy also needs to be monitored closely as increased money supply coupled with falling production could lead to demand outstripping supply and hyperinflation."
The euro fell to at $1.2562 <EUR=> while sterling was down at $1.4092 <GBP=>. The dollar rose 0.6 percent <.DXY> against a basket of major currencies.

"It appears that the battle is being lost. It doesn't add confidence."
