An increase in the so-called federal funds rate also probably would further strengthen the dollar, making U.S. exports more expensive and hurting the U.S. economy, World Bank Chief Economist Kaushik Basu said.
But the effects would be greatest in emerging markets, which already are dealing with volatility caused by concerns over China's economy and that nation's recent move to devalue its currency, he told the Financial Times.
"I don't think the Fed lift-off itself is going to create a major crisis but it will cause some immediate turbulence," Basu said. "It is the compounding effect of the last two weeks of bad news.... In the middle of this, it is going to cause some panic and turmoil.
Fed policymakers meet next week to decide if the U.S. economy is strong enough for an increase in the rate, which has been near zero since late 2008 in an unprecedented attempt to stimulate growth during and after the Great Recession.

The recent steep decline in financial markets has reduced inflationary pressures, negating the need for a rate hike right now, Summers said.
The World Bank and the
Worries by both institutions about the effects of a rate hike, particularly on emerging market nations, have increased recently.
"The world economy is looking so troubled that if the U.S. goes in for a very quick move in the middle of this, I feel it is going to affect countries quite badly," Basu said.
