In the past governments have funded their deficits – for example, they have borrowed in the bond market rather than through treasury bills. This is despite the fact that, for the past 80 years, the rate of interest on bonds has been greater than that on Treasury bills; that is, we have had an upward sloping yield curve.
I suggested in a recent blog that this was because governments correctly perceived that there were considerable economic risks in not funding, and that it was worth paying the additional cost to avoid these risks. Quantitative easing, which is a form of underfunding, must therefore have increased these risks. Defenders of QE need either to argue that these risks have not risen or that the benefits we have received from QE outweigh the rise in risks. To be consistent, those who hold that no additional risks have been incurred must now hold that governments should not have funded in the past and must now stop. But their silence is deafening, and such views are implausible, being held, I think, in the hope of dissuading discussion rather than from any conviction that they would survive much debate. Read more
