The monthly APRA banking statistics for December only partly confirm another widely held assumption of the impact of the credit crunch, namely that deposits in general are replacing hard-to-source and pricey wholesale funding for banks.They are, but the composition shows that business deposits are rising much faster (and especially recently) than household deposits.Business deposits increased by $32 billion, or 13 per cent in the six months from June to December 2007. Household deposits increased $30 billion, or 10 per cent over the second half of the year. (Each deposit pool is roughly $300 billion on APRA data, with the household deposit pool slightly larger than the pool of business deposits.)On a quarterly and monthly basis business deposits increased by 10 per cent and seven per cent. Household deposits increased four per cent and one per cent.These different trends are proving appealing to the strategies of a small number of deposit-takers.Only two banks recorded above-average growth in business deposits over the second half of 2007: BankWest, with growth of 21 per cent, and Commonwealth, with growth of 15 per cent. Rabobank also recorded very fast growth, but from a low base.National Australia Bank recorded tepid growth of four per cent in the business segment over six months.In the household deposit segment ING recorded growth of 16 per cent while NAB fared much better with growth of 11 per cent. Rabobank also excelled from a low base.
