LONDON, July 28 (Reuters) - Britain's blue chip index dipped by midday on Monday as banks fell on lingering concerns over the impact of a credit crunch and Ryanair <RYA.I> results weighed on British Airways <BAY.L>, while commodity shares gained.
By 1040 GMT, the FTSE 100 <
> was down 15.1 points, or 0.3 percent at 5,337.5 amid a flurry of results and trading updates. The UK blue chip index lost 0.4 percent last week, and is down more than 17 percent so far this year.Heavyweight energy stocks were in demand as crude prices <CLc1> rose above $124 a barrel, rebounding from a seven-week low. BP <BP.L>, Royal Dutch Shell <RDSa.L>, BG Group <BG.L> and Cairn Energy <CNE.L> were up 0.2 to 2.8 percent.
Miners rose along with firmer metal prices. BHP Billiton <BLT.L>, Rio Tinto <RIO.L>, Anglo American <AAL.L>, Eurasian Natural Resources <ENRC.L>, Antofagasta <ANTO.L>, Lonmin <LMI.L>, Xstrata <XTA.L> and Vedanta Resources <VED.L> put on between 1.5 and 5.1 percent.
"We're at an important stage in the market. Last week we seemed to hit a bit of the bottom and bounce off that," said Angus Campbell, head of sales at Capital Spreads.
"The market closed interestingly not as well as one would have expected. Today is a bit of carry on in sentiment with banking stocks being worse off and oil prices are a little bit higher."
Banks, however, headed in the opposite direction after credit ratings agency Standard & Poor's said it might cut some ratings on Fannie Mae <FNM.N> and Freddie Mac <FRE.N> and after U.S. regulators took over two small banks and sold them to Mutual of Omaha Bank.
The U.S. Congress approved a massive housing market rescue bill on Saturday, offering emergency financing to Fannie Mae and Freddie Mac, and setting up a $300-billion fund to help hundreds of thousands of troubled homeowners.
Royal Bank of Scotland <RBS.L>, HSBC <HSBA.L>, Barclays <BARC.L>, Lloyds TSB <LLOY.L> and Standard Chartered <STAN.L> were down between 0.5 and 3.8 percent.
HBOS <HBOS.L> dropped 6.5 percent ahead of its first half results on Thursday. A Reuters poll of four analysts expected HBOS profits to fall by more than half to about 1.3 billion pounds.
"When it comes to the UK banking sector, all eyes are going to be on further credit writedowns. We are going to move into the interim reporting period starting with Lloyds on Wednesday," said Richard Hunter, head of UK equity at Hargreaves Lansdown.
"We will have a much better picture in the next couple of weeks as to the health of UK banks."
Adding to negative sentiment, Citigroup cut European banks to "underweight" from "neutral".
And a survey by property consultant Hometrack showed British house prices fell for a 10th straight month in July to stand 4.4 percent lower on the year. [
