LONDON, April 24 (Reuters) - European stocks and the euro fell while safe-haven government bonds gained on Thursday as surveys showing deterioration in German corporate morale and the UK manufacturing sector raised concerns about Europe's economy.
The Ifo Institute's German business climate index fell to 102.4 in April, its lowest since January 2006, from 104.8 a month ago, against a forecast for a drop to 104.3. Current conditions and expectations indexes also fell.
A separate survey showed British manufacturing orders unexpectedly fell in April, weakening at their sharpest rate in 18 months.
The surveys came as bleak first-quarter results from Credit Suisse <CSGN.VX> overwhelmed positive reports from some European firms, fuelling fears that financial sector weakness due to the global credit crisis would spill over into the real economy.
"The market is beginning to question whether the euro zone is isolated from the U.S. slowdown or whether we're finally beginning to see a catch-up in the euro zone, softening in line with the United States, and that clearly is euro negative," said Adam Cole, global head of currency strategy at RBC.
The FTSEurofirst 300 index <
> was down 1 percent, dragged lower by banks <.SX7P> which fell more than 1 percent as a sector. MSCI's main world equity index <.MIWD00000PUS> was down 0.6 percent, off Monday's three-month high.Better-than-expected earnings results from Swiss engineer ABB <ABBN.VX> and German chemicals and drugmaker Bayer <BAYG.DE> contrasted with the unveiling of 5.3 billion Swiss francs ($5.26 billion) of credit-related writedowns and an above-forecast Q1 loss at Credit Suisse.
This followed Wednesday's worse-than-expected loss from Ambac Financial Group <ABK.N>, a U.S. bond insurer that struggled to raise capital earlier this year.
U.S. stock futures were down 0.6 percent <SPc1>, indicating a weaker open on Wall Street where key results from firms including Microsoft <MSFT.O>, Dow Chemical <DOW.N> and Ford Motor <F.N> are due later.
The interbank cost of borrowing three-month euro funds rose to a four-month peak of 4.83375 percent <LIBOR>, reflecting persistent stress in the money market.
The cost of borrowing sterling funds eased, but strains in funding since the outbreak of the credit crisis last August have darkened the UK housing market, with housebuilder shares falling broadly in London trading.
A barrage of gloomy earnings forecasts in Japan pushed Tokyo stocks lower <

FALLING CONFIDENCE
The decline in German corporate sentiment followed similar drops in business confidence in France, Belgium and the Netherlands.
"The message coming from the release of the business confidence indicators is unanimous across the main euro area countries: at the start of the second quarter, the outlook for the manufacturing sector has deteriorated substantially," Lehman Brothers said in a note to clients.
"In addition to the continued deterioration of the international environment, surging oil prices, the strong euro and slowing world demand probably explain these developments."
Emerging sovereign spreads <11EMJ> and emerging stocks <.MSCIEF> were steady on the day.
U.S. light crude <CLc1> eased 0.7 percent to $117.23 a barrel after hitting record highs of $119.90 earlier in the week. Gold <XAU=> ticked lower to $900.80 an ounce.
