RBA's Lowe says lower $A would be helpful

RBA governor Philip Lowe says a lower Australian dollar would be helpful to amplify the positive effects of its falls in recent years.

A lower Australian dollar would be helpful in amplifying the economic benefits of its recent falls, Philip Lowe has said at his first appearance as Reserve Bank governor.

"Of course most central banks say the same thing - most people would like a slightly lower exchange rate and I think it reflects the deficiency in aggregate demand in the global economy," Mr Lowe told a hearing of the House of Representatives economic committee in Sydney.

"Many of my peers think the same, but of course we can't all have a lower exchange rate," he said.
