NEW YORK, Aug 21 (Reuters) - World stocks and the dollar rose on Friday after a sharp jump in U.S. home sales and an optimistic outlook from Federal Reserve Chairman Ben Bernanke stoked optimism of a global economic recovery.
European shares rose to their highest close since early November and the euro rose to its highest level against sterling in nearly one month after a euro zone manufacturing and services survey showed more improvement than expected.
A 7.2 percent rise in U.S. existing home sales in July that resulted in the fastest sales pace in two years, reported by the National Association of Realtors, further ignited markets. It was the fourth straight monthly rise and signaled that the end could be in sight for dropping home values and rising defaults.
"Cracking set of home sales from the U.S.," said Jim Wood-Smith, head of research at London-based Williams de Broe. "It is more fuel on the fire of the bull market."
Comments by Bernanke at a Fed conference that prospects for a return to global growth appeared good in the near term, even though growth is likely to be slow and unemployment to remain high, fueled the positive sentiment.
U.S. stocks rose to their highest levels of the year. The Dow Jones <.DJI> industrials average rose 1.5 percent to 9,486.23 points, while the Standard & Poor's 500 index <.SPX> increased 1.6 percent to 1023.42 points, its highest in 10 months. The Nasdaq composite <.IXIC> rose 1.1 percent to 2,011.09 points.

In Europe, banking stocks led gains. The European FTSEurofirst 300 index <.FTEU3> gained 2.3 percent. The index is up nearly 50 percent since reaching a lifetime low in early March and is up about 16 percent for the year.
The decline in the euro zone's dominant services sector almost came to a halt in August, and businesses' expectations for the future soared to their highest level in more than two years, according to a survey by Markit.

The MSCI world equity index <.MIWD00000PUS> increased 1.49 percent to 274.10, it highest since its freefall in during the flashpoint of the financial crisis in October 2008.
Emerging stocks <.MSCIEF> rose 1.2 percent. Chinese stocks <.SSEC> climbed 1.7 percent, led by banks after earnings.
"The most decisive thing now is the Chinese stock market, and as long as the Chinese market holds up, the risky assets will hold as well," said Koen De Leus, economist at KBC Securities, the equities arm of Europe's KBC Group.
DOLLAR HIGHER
The U.S. dollar rose versus the yen on Friday after the U.S. data and the Fed comments supported views of a global economic recovery and increased risk appetite among investors. This push prices lower and yields higher on U.S. Treasury bonds, which reflected concerns about growing supply of national debt and the inflation it might bring.
