Lower interest rates are lifting measures of consumers' satisfaction with banks. Roy Morgan Research said that in May 2013 consumers' satisfaction with the big banks increased to a 17-year high of 79 per cent, up from 76.2 per cent in May 2012. Norman Morris, industry communications director for Roy Morgan, said this improvement of 2.8 percentage points was largely due to a 4.3 percentage point increase in the satisfaction level of the Big Four's home loan customers, as a result of five decreases in the cash rate by the Reserve Bank of Australia over the last year. Over the last 12 months, ANZ, NAB and Westpac had bigger increases in the satisfaction levels of their mortgage customers compared with that of their non-mortgage customers. Morris noted that "sixteen other smaller banks all have higher satisfaction levels than the best of the Big Four. The average satisfaction level for all of the banks outside the Big Four in May 2013 was 85.0 per cent compared... [with] 79.0 per cent for the Big Four."
