A quote from Mervyn King, Governor of the Bank of England, in 2004 agreeing with Alan Greenspan the Chairman of the Federal Reserve. Perhaps he should have looked at the plot below which I put together with data from the Bank of England's website.
Note the discontinuity in the mortgage lending plot. This occurs where there is a change in the source of the numbers from BoE derived to mortgage lender derived. It is almost as if the BoE want to disown the data.
