You may well be comfortable with it but that does not mean it is either equitable or sustainable in a normal banking environment. To some extent I feel that I am arguing against my core points on the initial post now, but to be fair I never postulated a position where low margin historic loans should be subsidized by higher margin current loans. I.e. the historic decisions made by banks in formulating the Tracker products were based on risk assessments made at that time together with an acceptance of a relatively low return on these products. Low profitability or even losses on these products should not be used as an excuse to increase rates on other clients who were not part of the Tracker agreements.
From a banking and commercial perspective I acknowledge and accept Brendan's point that SVR mortgages should be viewed on a stand-alone basis. Banks charge high SVR rates because they can!! Not because they are assessing their mortgage book on a holistic basis! This is simple economics. The banks currently have a Cartel and while competition is virtually non-existent they will charge their clients the highest price the market will bear. The rates now being applied to SVR's are based on that approach rather than a risk based one as postulated earlier. Naturally, risk is a factor in identifying the break-even cost of the mortgage product but the resultant additional margin is based on both competition and income growth. Competition is currently a non-factor so income growth is the predominant factor.
