Today, ONS published its second estimate of GDP for the 4th Quarter of 2015. The annual rate of change (compared to Q4 2014) was 1.9% for both real and nominal GDP. In Q3, the real and nominal rate of change was 2.1%. Identical in both quarters.
We have to go back to 1959/60 to find a similar case. True, in Q4 of 1999, there was a single moment when real and nominal came together – in that case at 3.7% - but that was ephemeral.
