SYDNEY, March 8 Reuters The Australian and New Zealand dollars rose against the greenback on Monday as the passage of a 1.9 trillion stimulus bill in the worlds largest economy buoyed appetite for risk, underpinning commoditylinked currencies.

The Aussie rose 0.3 to 0.7701, after falling for two consecutive weeks. It hit a 3year high of 0.8007 on Feb. 25, as the recent rout in global bond markets weighed on risksensitive currencies.

The kiwi dollar rose 0.30 to 0.7165, after having also fallen in recent weeks. It hit its highest in three and a half years at 0.7463 on Feb. 25.

Both currencies have benefited from unprecedented global fiscal and monetary stimulus during the COVID19 pandemic.

But the rapid global economic rebound has more recently fuelled concerns about inflation, pushing global bond yields higher, and hurting appetite for riskier assets.

The Aussies rejection at 0.80 late February has extended, though the brighter Australia and U.S. growth outlook has helped the currency stabilise, said Sean Callow, senior currency strategist at Westpac.

With a relatively quiet local data calendar, the Australian dollar is being supported by global factors, such as rising prices for oil and metals, according to traders.

Commodities have been volatile but spot iron ore has held above 170 per tonne, key to Australias record 10.1 billion trade surplus in January, Callow added.
