Ben Bernanke's dollar crisis went into a wider mode yesterday as the greenback was shockingly upstaged by the euro and yen, both of which can lay claim to the world title as the currency favored by central banks as their reserve currency.

Over the last three months, banks put 63 percent of their new cash into euros and yen -- not the greenbacks -- a nearly complete reversal of the dollar's onetime dominance for reserves, according to Barclays Capital. The dollar's share of new cash in the central banks was down to 37 percent -- compared with two-thirds a decade ago.

Currently, dollars account for about 62 percent of the currency reserve at central banks -- the lowest on record

Bernanke could go down in economic history as the man who killed the greenback on the operating table.

After printing up trillions of new dollars and new bonds to stimulate the US economy, the Federal Reserve chief is now boxed into a corner battling two separate monsters that could devour the economy -- ravenous inflation on one hand, and a perilous recession on the other.

"He's in a crisis worse than the meltdown ever was," said Peter Schiff, president of Euro Pacific Capital. "I fear that he could be the Fed chairman who brought down the whole thing."
