LONDON, Jan 27 (Reuters) - Global stock markets fell again on Wednesday, hitting their lowest in two months as investors fretted about a monetary squeeze from central banks around the world and also the impact of tightening U.S. banking regulation.
European markets <
> were down 0.2 percent, well off their lows as Wall Street looked set for a modestly positive start.Asia stocks <.MIAPJ0000PUS> had a 9th straight day of losses on continued reverberations over China's credit tightening this week.
Investors were also on edge as the U.S. Federal Reserve was due to end its latest two-day policy meeting later in the day.
While the meeting is expected to yield little in terms of a near-term policy shift, traders will scour its statement for clues on when it may wind down its policy of quantitative easing -- effectively money printing via purchases of bonds.
What is more, the meeting is taking place amid a fierce Senate debate over whether Fed Chairman Ben Bernanke should be appointed for a second term, another factor weighing on investor confidence this week.
There were also concerns about the intensifying regulatory backlash against U.S. and global banks, captured by U.S. President Barack Obama's latest proposals to limit the size of banks, their proprietary trading and their links to hedge funds.
"There are worries about the Fed phasing out quantitative easing," said Bernard McAlinden, investment strategist at NCB Stockbrokers. "There are also still worries about Obama's plans for banks, and Chinese growth."
"We're well into a major correction now, and this is about as big as most corrections get. The outlook is for some sideways trading," he said.
ASIA, EMERGING MARKETS RATTLED
Risk aversion everywhere was heightened by regulatory concerns, China tightening, the Fed meeting and sovereign debt worries in Greece and elsewhere.
The premium investors demand to hold 10-year Greek government bonds rather than benchmark German Bunds jumped to a euro lifetime high after the Greek finance ministry said there was no deal to sell bonds to China.
Ten-year Greek bonds yielded as much as 345.6 basis points over German Bunds after the comments denying press reports Greece planned to sell about 25 billion euros of its debt to China. [
]"They've denied the China sale story and that was the only thing that was keeping the market in," said a trader in London.
The dollar <.DXY> was flat against a basket of currencies after earlier rising.
"Concerns over China and Greece are still in the background. The uncertainty all this suggests is likely to keep risk on the back foot," said Gavin Friend, currency strategist at National Australia Bank.
Euro zone government bonds yields <EU10YT=RR> were higher.
