* China raises interest rates for first time since 2007
* World stocks, commodities fall; dollar extends gains
By Dominic Lau
LONDON, Oct 19 (Reuters) - World stocks, commodity prices and the Australian dollar fell on Tuesday after China raised its interest rates for the first time since 2007 to keep a rein on its booming economy.
The People's Bank of China said it would raise its benchmark one-year lending and deposit rate by 25 basis points effective from Oct. 20.
World stocks measured by MSCI All-Country World Index <.MIWD00000PUS> fell 0.4 percent and the Thomson Reuters global equity index <.TRXFLDGLPU> dropped 0.9 percent, while the MSCI emerging market benchmark <.MSCIEF> slipped 0.6 percent.
The dollar index <.DXY>, which tracks the U.S. currency against a basket of currencies, rose 0.8 percent after hitting the day's high of 77.592.
"The PBOC move follows a clear need by the Chinese authorities to take out some of the heat from the economy. Whether this move will lead to a broader move on its currency is open to debate," said Simon Derrick, head of currency research at Bank of New York Mellon.
"It certainly leads to speculation that the U.S. and China are in some sort of a deal which will perhaps see the U.S. taking a more gradualist approach to quantitative easing. The dollar has already moved higher after this news."
The greenback was earlier supported by comments from U.S. Treasury Secretary Timothy Geithner in favour of a strong dollar.
The Australian dollar <AUD=D4>, seen as a proxy of China's economic growth because of the country's commodity exports to China, fell to the day's low of $0.9805 from $0.9880.
Futures on the tech-heavy U.S. Nasdaq Composite index <NDc1> extended losses, down 1.3 percent to indicate a weaker opening, after Apple <AAPL.O> reported weaker-than-expected gross margins and iPad shipments disappointed investors.
Futures for the S&P 500 <SPc1> and the Dow Jones <DJc1> fell 0.2 and 0.6 percent, respectively.
Bank of America <BAC.N>, the largest U.S. bank by assets, said its third quarter net loss quadrupled from a year ago, as the bank recorded a previously announced $10.4 billion goodwill charge for its card business.
In Europe, the FTSEurofirst 300 <
> index eased 0.1 percent after trading in positive territory before Chinese rates announcement.As China is a major consumer of commodities, the reaction was broadly bearish. Copper prices <MCU3> lost 1.6 percent and gold <XAU=> fell 1 percent, while oil prices <CLc1> dropped 1.6 percent to trade below $82 a barrel. Commodity prices and emerging market assets have been buoyed by expectations of another round of money-printing by the U.S. Federal Reserve to stimulate a flagging recovery as investors searched for higher yields, while the dollar has come under pressure against other currencies.
Emerging market shares have gained more than 12 percent this year, outpacing a 6-percent rise in global equities.
The market is looking for further clues on the size of the quantitative easing, and will scrutinise any comments from Fed Chairman Ben Bernanke and other U.S. central bank officials later in the day.
