"There is a lot of volatility at the moment, and it is being created by hedge funds which represent some of Europe's richest individuals," he said.

In Asia, Japanese stocks rebounded on Friday from a historic fall the previous session as positive sentiment regained some momentum following strong overnight gains on Wall Street.
Still, market sentiment remained cautious amid continuing concerns about the financial crisis and prospects of a worldwide recession.

"So they are buying into relatively safe stocks."

Kevin Rudd, the Australian prime minister, announced an emergency meeting with the country's top business leaders on Friday to tackle the threat of global recession.
