LONDON - Investors were edgy Wednesday ahead of the appearance of U.S. Federal Reserve chairman Ben Bernanke before lawmakers in Congress.
Following a run of upbeat U.S. economic news, largely related to housing and jobs, there's been talk in the markets that the Fed may soon put a brake on its super-easy monetary policy, which has boosted liquidity in financial markets over the past few years.
However, on Tuesday, regional Fed chief James Bullard said the Fed should continue its monthly $85 billion in bond purchases, which drives down interest rates and thus encourages lending and spending, to help spur the U.S. economic recovery.
One aspect of the monetary stimulus, which has been replicated by a number of other central banks around the world, including most recently the Bank of Japan, has been to send stock indexes flying despite a patchy recovery from recession in many parts of the world.
Over the past few weeks, a number of the world's main markets, such as the Dow Jones and Germany's DAX have recorded a series of all-time highs, while others such as Japan's Nikkei and Britain's FTSE 100 have hit multi-year highs.
"So far, Bernanke has remained pretty dovish, which is what I expect more of today," said Craig Erlam, market analyst at Alpari. "However, any hawkish undertones from Bernanke could spark some panic in the markets."
Ahead of the testimony which starts at 1400 GMT, stocks drifted lower.
In Europe, the FTSE 100 was down 0.2 percent at 6,790 while the DAX fell 0.3 percent to 8,443. The CAC-40 in France was 0.6 percent lower at 4,011.
