Banks have made up the ground they lost in customer satisfaction late last year and early this year, following the out-of-cycle rate increases in November. Retail bank customer satisfaction ratings released by Roy Morgan Research yesterday show all but a handful of institutions improved their ratings over the months from March to June. The big improver was Citibank - up 18.1 percentage points (Roy Morgan cautions that Citibank has a small and volatile sample size). Other institutions that improved their ratings over the period were Bankwest (up 4.6 percentage points), Macquarie Bank (up 3.2 percentage points) and Bank of Queensland (up three percentage points). Among the majors, the big mover was National Australia Bank (up 2.8 percentage points), followed by Westpac (up 2.2 percentage points), ANZ (up 2.1 percentage points) and Commonwealth Bank (up 1.8 percentage points). Among the banks, ING Direct has the highest rating, with a score of 88.6 percent. However, Teachers Credit Union has the highest rating of all out of all the financial institutions, with a satisfaction score of 92.1 per cent. Roy Morgan's latest business customer ratings, also released yesterday, show a similar, although more muted, trend. Banks improved their ratings by an average of 0.2 percentage points over the months from March to June. Westpac was the big mover among the majors, followed by ANZ. Medium and large business drove the improvement in sentiment, followed by micro businesses. Small business (turnover $1 million to $5 million a year) reported lower satisfaction. DBM Consultants reported on Monday that business customer satisfaction with the major banks was at record levels. However, DBM found it was micro business that was driving the improvement in sentiment, while large businesses were less satisfied. And, while Roy Morgan has ANZ as the top-rated business bank, DBM gives the gong to Westpac.
