G20 Supports Asia Ahead of US Employment Data

Efforts by G20 leaders convinced investors that policy makers were united enough to keep a risk taking rally alive Friday, pushing up Asian markets higher for a fourth day and knocking the yen to a six-month low against the Australian dollar.

The perception of global policy coordination added to a growing optimism based on sprouts of economic recovery around the world in the last month. For example, a gauge of Chinese manufacturing in March released on Thursday reflected expansion for the first time since September 2008.

Though caution reigned ahead of the latest U.S. payrolls figure due later Friday, views on the medium-term outlook improved markedly after the Group of 20 pledged $1.1 trillionin additional funds for the International Monetary Fund and to support global trade finance.

The yen took an early beating against higher yielding currencies such as the Australian and New Zealand dollars but then regained its footing.

Oil futures is currently trading above $51 a barrel in the Asian session.

Japan's Nikkei 225 Average rose 0.3 percent to a three-month closing high, boosted by increasing optimism about the U.S. economy and active foreign buying of blue-chip exporters such as Sony.

South Korea's KOSPI ended half a percent higher, but gains were limited as shares took a breather following their latest run of advances.

Australian shares closed up 1.5 percent, their highest level in nearly three months, as tentative hopes the global economy may have found a bottom spurred buying of blue-chip bank and mining stocks. But shares in gold miners dropped after gold prices fell below $900 an ounce on renewed talk of gold sales by the International Monetary Fund, and reduced safe-haven demand as Wall Street rallied.
