I knew that the September 2014 changes to the National Accounts were big, but having a cursory look at Business Investment has been eye opening. The chart below shows the total amount (£ million), as of February 26th 2015, versus June 2013. The 2009 recovery phase is a stunning contrast. I've heard informally macro forecasters suggest that we just rip up everything we thought we knew. Why isn't this bigger news?
