LONDON, June 27 (Reuters) - Britain's blue-chip share index was driven lower by banks and retailers by midday on Friday, adding to the previous session's steep declines, but losses were limited by robust oil shares that tracked record crude.
By 1128 GMT, the commodity-heavy FTSE 100 <
> was down 9.0 points, or 0.16 percent, at 5,509.2 points, after slipping 2.6 percent to its lowest close since late March on Thursday.It has fallen 15 percent this year.
Investors fretted about the financial sector, which was worst hit by a credit market crisis that began last year. Sentiment received a further blow as mid-cap Bradford & Bingley <BB.L> tumbled 18 percent after entrepreneur Clive Cowdery scrapped his plan to inject nearly $800 million into the company, saying the lender's "entrenched" refusal to open its books made a deal impossible.
"The market does remain very nervous. In the short-term, there is a powerful mix of negativity," said Henk Potts, equity strategist at Barclays Stockbrokers.
"You have got a nightmare oil price and runaway inflation, which is eroding real wages and has the potential to further reduce household demand," he added.
Energy stocks gained on the back of record high crude prices, which have doubled in a year on supply disruptions and geopolitical tensions in the Middle East. Rising flows of cash into commodities from investors seeking to hedge against inflation and the weak dollar have also added to gains.
Royal Dutch Shell <RDSa.L>, gas producer BG Group <BG.L>, Cairn Energy <CNE.L> and Tullow Oil <TLW.L> added between 1.3 and 5 percent.
Miners also gained on firmer metals prices, with BHP Billiton <BLT.L> up 0.6 percent and Eurasian Natural Resources <ENRC.L> rising 2.3 percent.
Major world stocks fell to a three-month low on the back of record high crude prices above $141 a barrel and a deteriorating global inflation picture.
BANKS STRUGGLE
Shares in HBOS <HBOS.L> fell 1.6 percent to 273.45 pence and below their 275 pence rights issue price on persisting concerns about its exposure to a weak UK economy and housing market and the threat that a big chunk of shares will not be taken up during its rights issue.
Barclays <BARC.L> shed 2.3 percent and HSBC <HSBA.L> dropped 0.1 percent.
"Aside from the credit crunch, which has been with us for some while now, the position of banks looks even more precarious than it had been a short while ago," said Mike Lenhoff, chief strategist at Brewin Dolphin.
"Their capacity to finance economic growth appears to be diminishing by the day. So long as banks remain under pressure, the markets are going to remain under pressure."
Food and drug retailers also slipped, with high prices forcing consumers to cut their spending. Superstores struggled to retain their market shares amid concerns that the economy was slowing.
Britain's economy grew more slowly than previously thought in the first quarter as the service sector recorded its weakest performance in more than a decade, official figures showed.
The world's third-largest food retailer Tesco <TSCO.L> fell 1.7 percent, Britain's third-biggest supermarket group J Sainsbury <SBRY.L> shed 2.4 percent and Britain's fourth-biggest supermarket group Wm Morrison <MRW.L> lost 1.8 percent.
Investors will focus on U.S. core PCE data for May, due at 1230 GMT, and Reuters/University of Michigan consumer sentiment data for June, due at 1355 GMT. (Editing by David Cowell)
