I have seen this graph (or similar) in several places. It shows how the market has consistently and incorrectly predicted interest rates will rise back to normal levels. With the benefit of hindsight, has anyone produced a reasonable explanation as to why the market got it so wrong?
I’ll give one technical and one economic reason: first, if you believe in the zero bound for interest rates (bank of England will not set a negative short rate) then mathematically, if the current bank rate is close to zero (as it was post the 2008 crisis), then the distribution of rates 2-3 years forward is going to be biased upwards. Secondly, what happened economically during this period was that central banks saw that even with rates close to zero, inflation was not being stoked and in fact deflation was more of a worry. Hence the central banks never were able to raise rates as much as the forward curves expected.
