Interesting view from Cullen Roche:
Most fixed income traders view long rates as a function of the economy and short rates as a function of the Fed’s views on the economy. So, when the Fed increases rates it means that the Fed thinks the economy is improving and needs some tightening so it doesn’t cause the Fed to create too much inflation and overheat the economy. But fixed income traders account for this and front-run the Fed’s thinking by trying to anticipate their views on the economy. Said more simply – long rates are a function of short rates for the most part. And the fact that long rates are remaining low means that fixed income traders increasingly believe that we’re in a permanent state of low interest rates.
