Is a global economic recession likely? If so, what might trigger it? Willem Buiter, Citi’s chief economist and the Financial Times’ erstwhile Maverecon blogger, answers these questions: “Yes” and “China”. His case is plausible. This does not mean we must expect a recession. But people should see such a scenario as plausible.

Mr Buiter does not expect world output to decline. The notion here is a “growth recession”, a period of growth well below the potential rate of about 3 per cent. One might imagine 2 per cent or less. Mr Buiter estimates the likelihood of such an outcome at 40 per cent.

His scenario would start with China. Like many others, he believes China’s growth is overstated by official statistics and may be as low as 4 per cent. This is plausible, if not universally accepted.
