The Japanese yen plummeted across the board on Monday morning in Asia as worldwide equities rally and the global optimism buoyed by positive comments from U.S. Federal Reserve Chairman Ben Bernanke increased investors' risk appetite. The Japanese currency tumbled to new multi-month lows against its major counterparts.

The U.S. Federal Reserve Chairman Ben Bernanke said last week that he will use all tools available to him to stabilise financial markets. Bernanke said on Friday that programs enacted by the Federal Reserve to unfreeze the credit markets are working. Bernanke also praised the actions of policymakers as having lowered the cost and increased the availability of credit. In the midst of extraordinarily challenging times for the financial system and economy, Bernanke stated that he is confident that growth will be restored.

The positive comments from Bernanke eclipsed the negative data from the U.S. on Friday, with a greater-than-expected fall in non-farm payrolls in March took unemployment rate to a 25-year high of 8.5%.

The US Department of Labor said on Friday that non-farm payroll employment fell by 663,000 jobs in March following an unrevised decrease of 651,000 jobs in February. The drop in jobs came roughly in line with economists' expectations of a decrease of 658,000 levels. With the continued decrease in jobs, the unemployment rate rose to 8.5 percent in March from 8.1 percent in the previous month, in line with expectations. More than 5 million American have lost their jobs since the U.S. economy slipped into recession in December 2007.

Separately, the Institute for Supply Management released its report on activity in the service sector for March, showing that its index of activity in the sector unexpectedly fell to 40.8 in March from 41.6 in February, with a reading below 50 indicating a contraction in the sector.
