(Recasts with latest moves, Wall Street outlook)
By Natsuko Waki
LONDON, April 23 (Reuters) - European stocks slipped and Wall Street was set for a weaker open on Wednesday as fresh concerns about the health of the banking sector weighed, while oil prices and the euro stepped back from recent record peaks.
The chief executive of German bank HVB <HVMG.DE>, a unit of Italy's UniCredit <CRDI.MI>, said the bank will have significant writedowns in the first quarter given financial market turmoil.
Ambac Financial Group <ABK.N>, a bond insurer that struggled to raise capital earlier this year, posted a bigger-than-expected quarterly core loss per share due to its exposure to credit derivatives.
Investors, since the start of the month, have bought into stocks as first-quarter earnings results have so far shown firms are escaping the worst case scenario of plunging profits due to the credit crisis.
However, the financial sector -- the epicentre of the crisis -- is undoubtedly getting hit and an expected slowdown in global growth could weigh on corporate profitability going forward.
"The key issue over the next week is whether analysts reset expectations. As U.S. and UK GDP weakens, investors have still not factored in a slowdown, and they may start doing this," said Justin Urquhart Stewart, investment director at 7 Investment Management.
The FTSEurofirst 300 index <
> were down 0.7 percent while MSCI main world equity index <.MIWD00000PUS> erased gains to stand slightly down on the day. Banking stocks <.SX7P> fell more than 2 percent, one of the worst performers in Europe.U.S. stock futures were down 0.4 percent <SPc1>, indicating a weaker open on Wall Street later. Key U.S. earnings results due later include Boeing <BA.N> and Apple <AAPL.O>.
In the London interbank money market, the cost of borrowing three-month dollars <LIBOR> remained at a six-week peak of 2.92000 percent, indicating persistent stress in money markets.
The euro was down 0.2 percent at $1.5964 <EUR=> after rising to record highs above $1.60 on Tuesday.
Emerging sovereign debt spreads <11EMJ> tightened 1 basis point while emerging stocks <.MSCIEF> rose 0.3 percent.
The June Bund future <FGBLM8> rose 20 ticks, gaining support from steady U.S. Treasuries in Asia.
INFLATIONARY THREAT
U.S. light crude <CLc1> stood at $117.54 a barrel, down 0.4 percent on the day, after setting a record peak of $119.90 on Tuesday.
Gold <XAU=> ticked lower to $918.30 an ounce, while Shanghai copper futures rose and London tin futures hit a record high. U.S. rice futures climbed more than 2 percent to a fresh all-time peak <RRN8>.
Firmer energy and commodity prices are a double-edged sword for stocks as they boost energy firms and emerging market assets but also push up inflation which would erode corporate profits.
Rising prices are grabbing attention around the world. The Australian dollar hit a 24-year peak against the U.S. currency <AUD=> after data showed core inflation in the country accelerated to its fastest pace in nearly 17 years in the first quarter.
In the euro zone, recent comments by European Central Bank officials focusing on inflation raised expectations that the next move in interest rates would be a rise.
Some analysts say even a U.S.-led economic slowdown as a result of the credit crisis might not be enough to tame inflation risks.
"The U.S. slowdown has not been of dimensions sufficient to ease global resource price pressures. With the bulk of the demand side of the commodity shock being generated by developing economies, the U.S. recession would have had to be of savage proportions to tame the commodity inflation trend," noted Tim Bond, head of global asset allocation at Barclays Capital.
"Inflation risks will quickly, perhaps even seamlessly, move to replace credit risks as the major threat." (Editing by Stephen Nisbet)
