The cost of mortgages is on the up despite bank’s costs falling to record lows. The cost of three and five year fixed mortgages has risen again despite bank’s paying less to obtain the funds they lend.

It means that for a £100,000 mortgage, the banks are making £515 more annual profit than they were just nine months ago in January. Figures show that the average price of a three year fixed rate mortgage increased from 4.67% in July to 4.81% at the end of August. For five year deals the price increased from 6.68% to 5.72%.

At the same time, the three year interest rates paid by the banks on the wholesale money markets was 3.3% and five year rates were 2.6 %.

But the biggest cash cow for banks are tracker mortgages. Banks are borrowing funds for these products at 0.7% and lending it out on tracker mortgages at 3.84%.

In our view these represent market forces where the demand for mortgages simply exceeds the volume of funds which banks, post credit crunch, are prepared to supply. Until demand and supply come more into balance, we are likely to see the banks making hay whilst the sun shines and taking the opportunity to boost their profits and balance sheets.
