PARIS, May 26 (Reuters) - European stocks were slightly down around midday on Monday, falling for the fourth time in five sessions as fresh asset writedown fears at UBS <UBSN.VX> knocked banking shares lower.
Crude oil prices <CLc1> holding above $130 a barrel also continued to put pressure on stocks as concerns over rising inflation persisted.
Nokia <NOK1V.HE> retreated, down nearly 2 percent on market talk that the world's largest cellphone maker may cut its handset prices by as much as 20 percent in a bid to gain a bigger slice of the market from players like Motorola <MOT.N>.
Shares in Nokia's Asian rival LG Electronics <066570.KS> tumbled more than 8 percent on the rumours.
At 1050 GMT, the FTSEurofirst 300 <
> index of top European shares was down 0.1 percent at 1,320.83 points, after falling 3.2 percent last week.Both UK and U.S. markets were closed on Monday for a public holiday.
"The focus remains on oil prices, with concerns arising on how a number of sectors will cope with that. We've seen a sharp correction last week on airline stocks after company outlooks, citing high oil prices, disappointed the market," said Benoit De Broissia, analyst at Richelieu Finance, in Paris.
"The pressure from rising commodity prices is now so great that it reignites fears of second-round inflation, with wage hikes," he said.
The rise in oil prices aggravated existing worries among investors over inflation and stripped more than 2 percent off Japan's Nikkei <
> overnight.
WRITEDOWN FEARS RETURN
Banks were the heaviest negative weight on the market, with the DJ Stoxx index of European banks <.SX7P> down 0.7 percent, led by a decline in shares of UBS <UBSN.VX>, down 3.1 percent after the Swiss lender said it continues to be exposed to U.S. mortgages in its prospectus for its upcoming $15-billion rights issue.
UBS "continues to hold positions exposed to the United States residential mortgage and may record additional losses to such exposures," the bank said.
UBS will trade ex-rights on Tuesday and some traders said this was also already weighing on the company's stock.
UBS is Europe's largest subprime casualty so far, having written down $37 billion of assets hit by the U.S. subprime lending crisis.
