By Sitaraman Shankar
LONDON, Oct 22 (Reuters) - European shares slumped 5.4 percent on Wednesday, led by bank and energy stocks as investors added emerging markets ructions and waning commodity demand to their list of worries.
The FTSEurofirst 300 <
> index of top European shares ended down 50.03 points at 873.90 points. The benchmark has lost around 18 percent so far in October and is firmly on track for its worst month on record.Stocks have been battered this year by credit market problems which led to a full-blown financial sector crisis, the effects of which are spilling over into emerging markets.
On Wednesday, Hungary raised rates to defend its economy, Ukraine sought IMF help and Argentina moved to nationalise the country's private pension system.
Banks took most points off the index, with Santander <SAN.MC> tumbling 9.9 percent on concerns over Latin American economies after the Argentine move.
Other Spanish stocks also took a hit: oil group Repsol <REP.MC> fell 15.8 percent, while Telefonica <TEF.MC> lost 8.8 percent. BBVA <BBVA.MC>, which runs one of the funds to be nationalised, lost 9.1 percent.
"The crisis has moved up in scale, from companies to countries, and this is a logical progression of the same theme," said Philippe Gijsels, strategist at Fortis in Brussels.
"Everybody is deleveraging and as the water level goes down, the rocks are more apparent," he said. "The banks are being hit by fears that countries could start to default and quite a lot of bad loans will emerge."
Financials slumped with Royal Bank of Scotland <RBS.L> down 14 percent, ING <ING.AS> losing 11 percent after a Moody's downgrade of some ratings and AXA <AXAF.PA> off 8.2 percent.
Across Europe, Britain's FTSE <
> and Germany's DAX < > lost 4.5 percent and France's CAC < > fell 5.1 percent. U.S. stocks <.SPX> < > < > were 1.6 to 2.8 percent lower.
COMMODITIES SLIDE
The DJ Stoxx European basic resources index <.SXPP> was the worst performing sectoral benchmark in the region, sliding 9 percent as copper and aluminium prices sank to their lowest in almost three years.
Miners Xstrata <XTA.L> and Vedanta <VED.L> tumbled more than 13 percent, while Kazakhmys <KAZ.L> lost 15.5 percent and steelmaker ArcelorMittal <MTP.PA> fell 10 percent.
Energy stocks across Europe fell, with BP <BP.L>, Total <TOTF.PA> and Shell <RDSa.AS> down 5.5 to 6.2 percent as oil <CLc1> slid $4 to near $68 a barrel.
Among gainers, British Airways <BAY.L> rose 4.3 percent on market talk of interest from Cathay Pacific <0293.HK>. BA declined to comment.
Dutch telecoms group KPN <KPN.AS> rose 3.5 percent after it announced core earnings above expectations and set a 1 billion euro share buyback.
Slumping global equity markets have prompted policy responses that included concerted interest rate cuts and massive bank bailouts by governments.
Interbank borrowing costs mostly fell on Wednesday, with further steep falls in dollar rates and spreads indicating that the flood of liquidity pumped into the banking systems in recent weeks is easing money market constraints.
But recession fears, and worries over emerging markets, held centre stage.
"The old 'story' that has been put aside in the recent period of financial market crisis now comes back to the market's mind: recession fears," Commerzbank said in a note.
Fortis' Gijsels said he expected equity markets to bottom next year or in 2010. "We may see a big bear market rally before the end of the year but we will go down again," he said. (Additional reporting by Sarah Marsh; Editing by David Holmes)
