MonitorAllowing free capital flows is fast going out of fashion
The world is increasingly moving away from economic orthodoxy and accepting that capital controls are necessary to contain hot money

Hopes are high that when Premier Li Keqiang launches Shanghai's new free-trade zone this weekend, he will announce a major opening up of the mainland's financial system.
But if Li is indeed planning a big relaxation of Beijing's strict controls on cross-border capital flows, he will be swimming against the tide of international economic thought.
For decades economic orthodoxy dictated that emerging economies should open up their financial systems.
Any backsliding was roundly condemned, as in 1998 when in the depths of the Asian currency crisis Malaysia banned free capital flows to stabilise its currency, the ringgit.
Recently, however, orthodox opinion has reversed.
In the future, capital controls could prove not just useful, but essential, for some markets
Consider the Damascene conversion of Stanley Fischer. Between 1994 and 2001, as first deputy managing director of the International Monetary Fund, Fischer was closely associated with the Fund's hardline opposition to capital controls.
