By Dominic Lau
LONDON, Aug 14 (Reuters) - Britain's top share index rose 1.1 percent by midday on Thursday as firmer raw material prices boosted commodity stocks, though battered banks remain under pressure and Rolls-Royce <RR.L> eased on negative broker notes.
By 1041 GMT, the commodity-heavy FTSE 100 <
> was up 60 points at 5,508.6, recovering from the previous session's 1.6 percent loss and snapping a two-day losing run."I have been using this recent rally back up from the end of July ... to bank a few profits," said Tim Whitehead, head of portfolio services at Redmayne-Bentley.
"I am wary about the whole situation. It's encouraging that inflation pressure might recede a little bit with the oil prices going down, but the latest Bank of England report shows that food prices going up. That will bring pressure on wage inflation."
Energy stocks contributed more than 30 points to the index, as crude prices <CLc1> traded above $116 a barrel.
BP <BP.L>, Royal Dutch Shell <RDSa.L>, gas producer BG Group <BG.L>, Cairn Energy <CNE.L> and oil and gas services firm Petrofac <PFC.L> advanced 1.8 to 5.1 percent.
Miners were also standout gainers, tracking stronger metal prices. Rio Tinto <RIO.L>, BHP Billiton <BLT.L>, Anglo American <AAL.L>, Xstrata <XTA.L>, Antofagasta <ANTO.L> and Ferrexpo <FXPO.L> were up between 4.3 and 6.2 percent.
Banks were the top losing sector, with HSBC <HSBA.L>, Royal Bank of Scotland <RBS.L>, HBOS <HBOS.L>, Lloyds TSB <LLOY.L> and Barclays <BARC.L> down between 0.2 and 3.3 percent.
Analysts at Goldman Sachs said Barclays may need to write down 1.5 billion pounds more over the next 18 months, adding the bank has little room to absorb further material losses without the dividend potentially being cut or paid in shares.
HBOS, meanwhile, said it would cut up to 425 jobs and shut one of its five mortgage brands to new business as the group positions itself for a shrinking loan market and a drop in house prices.
