DP9378 Is the UK triple-A?

The immediate background to this paper is the downgrade of the U.K.'s credit rating in February 2013, the market's view that this should have occurred earlier and the emphasis in fiscal policy on reducing debt rather than recovery from recession. We propose a measure of the U.K. sovereign credit rating based on an open economy macroeconomic model that is simple to compute and easily automated. Whether based on an ad hoc debt-GDP limit or a DSGE model of an open economy, our measure downgrades the U.K.'s sovereign credit rating from the middle of 2008. From 2010 the rating improves and is nearly restored to triple-A by 2012.
