Negative interest rates debate steps up as Reserve Bank confronts COVID19 woes. Westpac chief economist Bill Evans wants the negative option at least on the RBA's radar

Could Australia be on the cusp of negative interest rates? 

Reserve Bank governor Philip Lowe says the prospect is unlikely, but Westpac chief economist Bill Evans says negative rates would stop investors hoarding money and lower the Australian dollar as the economy faces the end of JobKeeper payments in September. 

But Mr Evans tells ABC's Peter Ryan there is a risk that negative rates would further unsettle economic recovery.
