Fears of another interest rate rise have emerged after Reserve Bank governor Michele Bullock warned the central bank is prepared to raise rates again if needed, as Australia’s inflation remains stubborn. Ms Bullock’s warning comes ahead of key inflation data due to be released on Wednesday, with economists expecting underlying inflation to remain above the Reserve Bank’s target range. Asked whether the Government should be doing more to bring inflation down, Ms Rishworth stressed that interest rate decisions were a matter for the Reserve Bank’s independent board. Ms McKenzie argued the Government had failed to present a credible economic plan, leaving the Reserve Bank to rely on higher interest rates to cool inflation. Pressed on where a Coalition government would cut spending, Ms McKenzie said the Opposition would reduce migration, rein in spending on the National Disability Insurance Scheme and stop funding projects linked to the CFMEU.
