The world economy in 2016 is in a fragile state, with growth likely to dip below that registered in both 2014 and 2015. The mediocre performance of developed countries since the 2008–2009 economic and financial crisis is set to continue, with the added threat that the loss of momentum in developing countries over the past few years will be greater than previously anticipated. Without a change of course in the former, the external environment facing the latter looks set to worsen with potentially damaging consequences for their prosperity and stability in the short to medium run. More widespread contagion from unforeseen shocks cannot be ruled out, knocking global growth back even more sharply. The decision by the United Kingdom electorate to leave the European Union (EU) is such a shock.
