LONDON, Oct 30 (Reuters) - World stocks and the euro rallied on Thursday, boosted by sweeping gains in emerging markets after the U.S. Federal Reserve cut interest rates and opened swap lines to four developing economies.
The Fed slashed half a point off the fed funds rate to 1.0 percent and left the door open to further cuts, renewing weakness in the dollar but improving risk appetite as carry trade-favourite yen softened.
Japan and Germany also said they would plough billions of dollars into their economies, hoping to provide a cushion against a deep recession and complement a series of expected interest rate cuts. [
]"The Fed gave the market what it wanted and at the margin we're seeing more positive sentiment creeping back in. But underlying it all are deep-seated fears about global recession," said Nicola Chadwick, international economist at CBA.
The MSCI world equity index <.MIWD00000PUS> rallied by 3 percent, driven by gains of over 9 percent in the benchmark emerging equities index <.MSCIEF>.
Emerging equities have bounced by nearly 22 percent from four-year lows set on Tuesday.
They got a further boost from the International Monetary Fund's approval of a short-term financing facility for emerging market economies that have a good economic track record but are having difficulties accessing credit. [
]The Fed also opened up dollar liquidity aid beyond traditional markets, with four new $30 billion currency swap lines with Brazil, Mexico, South Korea and Singapore.

"This is a fantastic rally, but it is only a rally," said Justin Urquhart Stewart, director at Seven Investment Management.
"The rate cuts are encouraging. But we're dealing with a slump. It's not a matter of whether it's bad, it's a matter of how bad."
