The change in classification methodology implemented with retroactive effect to April 2008 is explained in Habermeier and others (2009). Note that changes in the classification of EAC countries at this time followed from the methodological change rather than a judgment that there has been a substantive alteration in the countries’ de facto exchange-rate policies.
