LONDON, Jan 31 (Reuters) - Britain's FTSE 100 <
> share index tumbled 1.4 percent at midday on Thursday as U.S. recession fears undermined banks and the index headed for its worst ever January.By 1221 GMT the FTSE 100 was down 84.1 points at 5,753.2 as shares slid across Europe. The UK benchmark index has shed about 11 percent so far in 2008 as persistent recession concerns have triggered global stock market ructions.
Bank shares stole 40 points off the FTSE on concerns that deepening problems for U.S. bond insurers could increase write-downs on troubled assets and deepening U.S. recessionary fears.
Barclays <BARC.L> fell more than 6 percent, Royal Bank of Scotland <RBS.L> shed 4.5 percent, HSBC <HSBA.L> dropped 2.5 percent, Standard Chartered <STAN.L> went down 3.6 percent and Bradford & Bingley <BB.L> lost more than 6 percent.
A negative note from Panmure, including "sell" ratings on the all the above banks, added to the gloom.
"It's the same thing that we've had since the beginning of the year," said Chris Iggo, strategist at Axa Investments.
"We need some interest rat cuts in the UK otherwise the bank sector is still going to struggle," he added.
"The Fed's doing its best to head off recession but the central banks in Europe haven't really got in the game yet and I think that is necessary before the FTSE can really stabilise."
The Bank of England is expected to cut interest rates next week in February to head off fears of slowing growth despite only a one-in-four chance of a recession, and end the year with rates at 4.75 percent, a Reuters poll showed last week.
U.S. stocks fell on Wednesday as speculation on CNBC television that credit rating firms would downgrade top bond insurers Ambac Financial Group <ABK.N> and MBIA <MBI.N> pushed shares in both companies down more than 10 percent, overshadowing a 50 basis-point cut in interest rates by the Federal Reserve.
With the long-mooted U.S. rate cut out of the way, investors eyeing U.S. data will now pin their focus on key jobs data due on Friday.
UNWANTED FRIENDS
Friends Provident <FP.L> was the standout mover in early trade, plunging 11.6 percent after saying it plans to sell fund manager F&C <FCAM.L> and high-end unit Lombard and cut 600 jobs in a radical overhaul to streamline the business, improve cash flow and boost profits.
