The household saving ratio fell for the fifth consecutive quarter, the national accounts for the June 2017 quarter show.The ratio fell from to 4.6 per cent from 5.3 per cent in March 2017, on a seasonally adjusted basis.Banks have experienced this in a softening in growth rates in household deposits, with annual growth rates in deposits at mid-2017 half the six per cent level of a year ago.Household spending "was supported by a continued raid on savings", Paul Bloxham, chief economist at HSBC Australia wrote in a note to clients yesterday.Martin North, principal of Digital Financial Analytics, positioned the fall in the saving ratio to a new post GFC low as "consistent with our research of household cash flow, where more than 26 per cent of mortgaged households are now relying on savings, credit cards and the like to manage the monthly budget."North argued "this cannot continue indefinitely, because household savings are not infinite, and they are also skewed in distribution terms towards those with more assets and net worth.  Stress resides among households with lower net worth and little or no savings."
