The dollar and the yen plunged in early Asian trading on Friday as the outcome of the G20 meeting boosted investors' risk appetite, but the currencies trimmed their losses later, as caution returned ahead of U.S. employment figures due later in the day, which is expected to show the US economy continued to lose jobs in March.

Economists estimate that the U.S. economy lost 656,000 jobs in March and look for an unemployment rate of 8.5%.

The job losses in February were 651,000, in line with the 650,000 jobs losses expected by economists. The unemployment rate based on the household survey was 8.1% in February, up from 7.6% in the previous month. Economists had been forecasting an unemployment rate of 7.9%.

Pointing to the decision to triple funding to the International Monetary Fund to $750 billion, Obama said that the G-20 would support developing countries.

The G20 leaders convinced investors that they were united enough to keep a risk-taking rally alive, lifting Asian stocks a fourth day today.
