A Roy Morgan Single Source survey, which was carried out in the year to May 2017, shows that Australia’s four major banks have increased their share of customers’ dollars ("share of wallet") over the last decade, which correlates with their improvement in satisfaction over this period. The Commonwealth Bank of Australia recorded the highest growth in share of wallet among the big four banks over the last decade (7.4%), although BankSA recorded the largest growth (12.4%). Meanwhile, the top quintile (or 20%) of banking customers, based on the value of all their banking products, now accounts for nearly three quarters (74.2%) of the total value of banking products. The best performer for "share of wallet" in the top quintile is Bank SA (60.3%), followed by CBA (58.1%).
