NAB to slash mortgage rates after RBA moveNAB will cut variable home loan rates in response to the Reserve Bank of Australia's latest cash rate decision. NAB will wipe the full 25 basis points from variable mortgage rates after the central bank once again moved to ease pressure amid weakening inflation. A 25 basis point reduction is expected to see NAB's lowest advertised variable mortgage rate – that on its Base Variable Home Loan – fall from 5.94% p.a. "Today’s RBA cash rate cut is a welcome change that should boost Australian optimism," NAB personal banking executive Ana Marinkovic said. NAB joins CommBank, Westpac, ANZ, and Macquarie in passing on the full RBA rate cut to its variable rate home loan customers.
