LONDON, Feb 18 (Reuters) - Banks drove European shares higher on Monday ahead of this week's key earnings data which will show their progress in writing down losses related to U.S. subprime mortgages, while platinum raced to new historic highs.
The dollar rose against a basket of major currencies after hitting 1-1/2 week low last week following disappointing U.S. data. Oil climbed above $96 a barrel, helping to erase earlier losses in emerging market assets.
Weekend news that the British government is to nationalise Northern Rock <NRK.L>, which fell victim last year to a jump in interbank lending rates as a result of the credit crisis, has also helped sentiment among British banks.
This week's earnings results from scandal-hit French bank Societe Generale <SOGN.PA>, peer BNP Paribas <BNPP.PA> and Britain's Barclays <BARC.L> will show the global banking sector's progress in writing down an estimated $300-400 billion of subprime losses.
The extent of the sector's damage from the credit crisis holds the key to investor risk sentiment and the performance of risky assets including stocks after some share indexes dipped into a bear market cycle -- a period of prolonged losses.
"This is a bear market, and there will be some rallies in it," said Justin Urquhart Steward of 7 Investment Management.
"The focus this week is going to be on the banks, as investors scrutinise their results to see if they've put off balance sheet things that should actually be on balance sheet, and whether we've actually been led a merry dance."
The FTSEurofirst 300 index <
> was up 1.4 percent while MSCI main world equity index <.MIWD00000PUS> was up 0.2 percent.U.S. financial markets are closed for Presidents Day holiday.
The iTraxx Crossover index <ITCRS5EA=GFI>, the mostly-widely watched indicator of European credit market sentiment, tightened to 565 basis points, after hitting record wides last week due to concerns about forced selling on credit products.
Emerging sovereign spreads <11EMJ> widened 3 basis points while emerging stocks <.MSCIEF> was steady on the day.
The March Bund future <FGBLH8> was down 0.3 percent.
SHINING PLATINUM
Platinum <XPT=> surged to $2,107 an ounce, gaining more than 20 percent since late January after South Africa, which accounts for 80 percent of global supply, was hit by power cuts that forced mines to shut for five days last month.
Gold <XAU=> was steady at $903.40 an ounce.
U.S. light crude <CLc1> rose 0.8 percent to $96.25 a barrel as an escalating row between OPEC member Venezuela and oil major Exxon Mobil <XOM.N> outweighed concerns about the effect of a slowing U.S. economy.
The dollar rose 0.3 percent against a basket of major currencies <.DXY>, gaining some support from firmer stocks and recouping some of the losses made on Friday after data showed U.S. consumer sentiment fell to a 16-year low.
Investors expect the Federal Reserve to cut interest rates by 50 basis points in March, on top of its rate reduction of 225 bps since September -- moves which have depressed the dollar.
"The lethal combination of weakening house prices, high energy prices, tighter lending and volatile asset markets will be difficult to overcome and even the prospect of further rate cuts could do little in this environment," Calyon said in a note to clients.
