plainly wrong.. aus banks have been dropping their mortgage rates in line with the overnight cash rate set by the RBA, however not passing through all BP's. Savings rates are not slashed nearly as much and have been relative to mortgage rates been much stronger. Why? banks have been trying to reduce reliance on wholesale offshore funding and more on domestic savings ie attracting them with a relative higher rate.
EDIT: http://www.rba.gov.au/publications/fsr/2012/sep/pdf/aus-fin-sys.pdf pg21
"The risks Australian banks could face from their use
of wholesale funding are being mitigated through
the ongoing compositional change to the liabilities
side of their balance sheets (see ‘Box A: Funding
Composition of Banks in Australia’). Deposit growth
has remained strong, at around 9 per cent in
annualised terms over the past six months, reducing
banks’ wholesale funding needs. However, the
strong competition for deposits has widened their
spreads relative to benchmark rates, contributing
to an increase in banks’ funding costs relative to the
cash rate. Deposits now account for 53 per cent of
banks’ funding, up from about 40 per cent in 2008"
Thx good info. That's a significant reduction in reliance on European credit markets. However, the amount remaining as reliant on international credit growth is still very very high as a proportion of the total.
