Australia's big banks insist they can't afford to pass on the Reserve Bank's interest rate cut, but angry mortgage holders are increasingly likely to respond by switching lenders.
An Ernst and Young report found that 66 per cent of people think there are better deals available than their present loans.
However, if lenders wanted to take advantage of people's desire to switch, they had to simplify what are currently complicated mortgage products.
Since the Reserve Bank cut the cash rate by 25 basis points to 3.25 per cent last Tuesday, Westpac, Commonwealth Bank and National Australia Bank cut their variable home loan rates by less than that, citing high deposit costs. ANZ will review its lending rates on Friday.
Only four out of 13 lenders that have so far responded have passed on the rate in full, according to financial comparison website RateCity.
