LONDON, Aug 26 (Reuters) - Britain's top share index slid 1.9 percent by midday on Tuesday as commodity stocks tracked weaker metal and crude prices on concerns over global growth, while lingering credit worries hurt banks.
By 1029 GMT, the FTSE 100 <
> was down 102.5 points at 5,403.1, underperforming other major European indexes after the UK market was closed for a holiday on Monday, when the other benchmarks fell. The UK index had rallied 2.5 percent on Friday."It's a little discouraging but I suppose it's something we have to expect in a way because we will be constantly shocked with credit worries," said Mike Lenhoff, chief market strategist at Brewin Dolphin.
"The banks have pretty well lost so much capacity to finance economic growth...the whole question about progressing is a little up in the air. At the same time, the central banks can't do much about it because inflation has accelerated from targets. The market is caught in a trap."
Lenhoff also said the corporate bond market had sensed there would be trouble in the corporate sector with spreads widening.
"Against this kind of background, it's going to be difficult for the equity market to make any progress," he added.
In the credit derivatives market, the investment-grade Markit iTraxx Europe index <ITEEU5Y=GF> was at 101 basis points, about 4 basis points wider versus late on Friday.
Energy stocks were the top-weighted loser on the index as crude prices <CLc1> slipped below $114 a barrel. BP <BP.L>, Royal Dutch Shell <RDSa.L>, gas producer BG Group <BG.L>, Cairn Energy <CNE.L> and Tullow Oil <TLW.L> shed 2.5 to 3.7 percent.
Energy services company John Wood Group <WG.L> slipped 2.6 percent despite posting a 44 percent rise in first-half profit and saying it expected to beat full-year expectations.
Miners also fell along with weaker metal prices. BHP Billiton <BLT.L>, Anglo American <AAL.L>, Xstrata <XTA.L>, Vedanta Resources <VED.L>, Kazakhmys <KAZ.L> Ferrexpo <FXPO.L> and Antofagasta <ANTO.L> lost between 3 and 9.2 percent.
Rio Tinto <RIO.L> reported a 55 percent rise in first-half earnings, boosted by its takeover of Alcan last year and record iron ore production feeding Chinese demand. [
]Rio shares were down 3.4 percent.
London Stock Exchange <LSE.L> sank 4.9 percent, making it among the top losers on the FTSE 100, following increased competition in the sector and general negative sentiment in the finance industry.
PERSISTING CREDIT FEARS
Banks were another standout loser, with Barclays <BARC.L>, Royal Bank of Scotland <RBS.L>, HBOS <HBOS.L>, Lloyds TSB <LLOY.L> and Standard Chartered <STAN.L> down between 1.6 and 3.8 percent. HSBC <HSBA.L> headed north, up 0.3 percent.
U.S. stocks fell sharply overnight as credit concerns hounded financial stocks while global growth worries hurt big technology and industrial companies. In Asia, Japan's Nikkei average <
> lost 0.8 percent.JPMorgan Chase <JPM.N> said the market value of its investments in Fannie Mae <FNM.N> and Freddie Mac <FRE.N> preferred stock has dropped by half to $600 million this quarter. [
]Data on U.S. new home sales for July and consumer confidence for August, both due at 1400 GMT, will provide further clues to the state of the world's largest economy.
Mid-cap Taylor Wimpey <TW.L>, however, soared 8.8 percent as traders cited market talk that the housebuilder could have reached a deal with its banks ahead of the firm's interim results, due later this week. The debt-laden builder was not immediately available for comment.
The rise in Taylor Wimpey shares boosted the housebuilding sector, with Bovis Homes <BVS.L> reversing earlier losses and trading up 2.1 percent despite reporting a slump in first-half profit following what it called the toughest period of trading in its life as a public company.
Liberty International <LII.L> surged 4.9 percent to top the FTSE 100 gainers after U.S. real estate investor Simon Property Group <SPG.N> raised its stake in Liberty to 4.22 percent, fuelling speculation Simon was set to bid for Britain's biggest shoppinga mall owner. [
