The pace of deposit growth at banks picked up in late 2010, a result perhaps of fading demand for credit, as well as efforts across the sector to increase the level of funding from this source. The Australian Prudential Regulation Authority put growth in household deposits at 1.5 per cent over the month of December 2010, 2.3 per cent over the December quarter and 8.8 per cent over the year.The one-month and three-month data points to an acceleration in the rate of deposit growth on top of the already high rates reported for banks over the last two years.When it comes to business deposits, the pick-up in growth rates is stronger still.APRA put growth in business deposits at 2.3 per cent over the one-month period, at 6.3 per cent over the three months and 13.2 per cent over the 12 months.National Australia Bank has garnered above-system growth in household deposits, as the accompanying table notes. The trend is true over the short term as well as the 12-month period featured in the table.This is especially true for NAB, which is reporting growth rates in deposits over one month and three months of roughly double that of the remainder of the banking system. This is likely a result of both the pricing and the improving product range of its UBank brand.Otherwise, most of the gains in market share in deposits are concentrated among niche banks and foreign banks, as the table highlights.Citibank, which is supporting the re-entry of Virgin Money into the banking market reports stand-out growth on household deposits (though balances in fact declined in December 2010).Rabobank, ME Bank and ING Direct are also reporting above-system growth in deposits.Bank of Queensland and Bendigo and Adelaide Bank are also picking up market share in business deposits, though their gains have been inconsistent over recent months.
