Interest rates for five year fixed rate mortgages are at a low of 3.61% at the moment, partly the result of the government's Funding for Lending scheme to make cheap money available to banks and building societies.
But the consequence is that savings rates have continued to suffer.
Instant access accounts pay an average of 0.98% in interest. That's including the annual bonuses some accounts offer.
And tax-free ISAs, excluding bonuses, are giving you just 0.81% a year.
Both of these average rates are plumbing new depths.
These are Bank of England's figures on quoted interest rate. The 5 year fixed rate mortgage number goes back to 1995, when it stood at 9.44%. Remember that!
