(Adds Ifo reaction, Wall Street outlook)

LONDON, Feb 26 (Reuters) - World stocks hit a three-week peak on Tuesday as upbeat results from Standard Chartered <STAN.L> and optimism on U.S. bond insurers brightened investor morale, while an upbeat German business survey boosted the euro.
European credit market sentiment improved with the cost of corporate debt insurance falling further, while commodity and energy prices came off recent lofty peaks, calming inflation concerns.
Asia-focused bank Stanchart reported a 27 percent rise in annual profit and said wholesale banking had a record January, easing concerns about the health of the banking sector hit by the six-month-old credit crisis.
Also helping sentiment, Standard & Poor's removed on Monday its threat to downgrade insurer MBIA <MBI.N> while a rescue plan for rival Ambac Financial <ABK.N> is set to be announced soon.
Investors have been spooked by the threat of credit downgrades of these "monoline" insurers due to their exposure to U.S. subprime mortgages.
Downgrades of the monolines, which provide cover against defaults in securitised debt, could trigger a wave of forced selling in bonds and lead to more losses by banks.
"The news we've had on the monolines have been risk appetite-friendly, commodities are coming back a little bit from their recent highs," said Ian Stannard, senior foreign exchange strategist at BNP Paribas.
The FTSEurofirst 300 index <
> was up 1.1 percent while the MSCI main world equity index <.MIWD00000PUS> rose half a percent to levels last seen early in February.Stanchart shares rose more than 6 percent while the broader banking sector <.SX7P> was up 2 percent.
U.S. stock futures were up around 0.1 percent <SPc1>, indicating a firmer open on Wall Street later.
The iTraxx Crossover index <ITCRS5EA=GFI>, most-widely watched indicator for European credit market sentiment, tightened to 529 basis points. The index widened to record levels last week due to concerns about forced debt selling.
The euro hit $1.4878 <EUR=> after the German Ifo corporate sentiment survey showed its headline index, based on a monthly poll of around 7,000 firms, unexpectedly rose in February. Interest rate futures trimmed expectations for a euro zone rate cut by end-June to 1-in-4 from 1-in-3 before the data.
OIL, GOLD OFF HIGHS
U.S. light crude <CLc1> fell 0.1 percent to $99.09 a barrel as expectations rose for higher crude stocks. Gold <XAU=> fell to $932.85 an ounce after the U.S. Treasury said it would support gold sales by the International Monetary Fund, which holds more than 3,000 tonnes of bullion.
Platinum <XPT=> also tracked gold lower.
A recent surge in commodity prices has fanned inflation concerns. A February survey by the Confederation of British Industry showed retailers expect to ramp up prices at the sharpest rate in more than a decade.
Inflation concerns could slow the pace of interest rate cuts by the Federal Reserve and other central banks keen to limit the effects of the credit crunch on the real economy.
"Inflation expectations remain critical and any significant deterioration on that front would be a trigger for financial market volatility," UBS said in a note to clients.
"With market sentiment highly dependent on further Fed easing, upward inflation pressure would certainly put the Fed on the defensive."
Interest rate futures expect the Fed to cut interest rates by half a point in March.
Emerging sovereign spreads <11EMJ> were unchanged while emerging stocks <.MSCIEF> rose a third percent.
The March Bund future <FGBLH8> was steady on the day.
