LONDON, June 4 (Reuters) - Britain's blue chip index slid 1.5 percent by midday on Wednesday as a firmer dollar weighed on commodity prices, hitting miners and oil shares, while banks took a beating on fresh funding concerns.
By 1012 GMT, the FTSE 100 <
> was down 91.6 points at 5,966.1, losing its grip on the key 6,000 mark and tracking weakness in U.S. stocks overnight amid signals from the Federal Reserve that it would be reluctant to cut interest rates again because of dollar-led inflation.The unusually explicit warning from Fed Chairman Ben Bernanke sent the dollar higher against other currencies, pushing down crude <CLc1> and other commodity prices.
"The index points that come off the lower oil prices are larger than the index points that go on the stocks that might potentially benefit from lower oil prices," said Darren Winder, equity strategist at Cazenove.
Oil shares were the biggest sectoral loser, knocking 31 points off the index. BP <BP.L> dropped 2.6 percent, Royal Dutch Shell <RDSa.L> shed 2.4 percent and gas producer BG Group <BG.L> lost 2.6 percent.
Miners also suffered, with BHP Billiton <BLT.L>, Rio Tinto <RIO.L>, Eurasian Natural Resources <ENRC.L>, Anglo American <AAL.L>, Xstrata <XTA.L> and Vedanta Resources <VED.L> off between 1.3 and 5 percent.
"The dollar actually rules the roost today," said Howard Wheeldon, a senior strategist at BGC Partners. "We are reminded that the dollar isn't just about oil, it has a significant effect on all commodities."
"Bernanke has told us what we probably had come to already accept but we needed the personal verification -- no more interest rate cuts."
In the UK, the Bank of England is expected to leave rates unchanged at 5 percent when it announces its verdict on Thursday.
SHIVERING BANKS
Banks felt a shiver from a tumble in Lehman Brothers shares on concern that it may need to raise more capital, with Barclays <BARC.L> down 3.1 percent, Lloyds TSB <LLOY.L> falling 1.2 percent, Royal Bank of Scotland <RBS.L> slipping 0.5 percent, HBOS <HBOS.L> easing 3.1 percent and Standard Chartered <STAN.L> losing 2.5 percent.
But Alliance & Leicester <ALLL.L> added 5 percent.
Also weighing on sentiment, a survey showed British consumer confidence fell further in May with people even gloomier about the state of the economy.
Marks & Spencer <MKS.L>, Kingfisher <KGF.L>, Home Retail <HOME.L> and Next <NXT.L> were down 0.7 to 1.9 percent.
Housebuilders remained under pressure, with Persimmon <PSN.L>, Taylor Wimpey <TW.L>, Barratt Developments and Bovis Homes <BVS.L> down 2.3 to 6.9 percent after UBS issued a negative sector note.
Index heavyweight Vodafone <VOD.L> shed 4.5 percent after going ex-dividend.
British Airways <BAY.L> climbed 3 percent ahead of the release of the airline's May traffic figures and as oil prices fell.
Associated British Foods <ABF.L>, Enterprise Inns <ETI.L>, Imperial Tobacco <IMT.L>, National Grid <NG.L> and WPP <WPP.L> also fell after going ex-dividend.
Ex-divs took nearly 15 points off the index, according to Reuters calculations. (Additional reporting by Michael Taylor; editing by Elaine Hardcastle)
