Currencies dominated this year’s annual meetings of the International Monetary Fund. More precisely, two currencies did: the dollar and the renminbi, the former because it was deemed too weak and the latter because it was deemed too inflexible. But, behind the squabbles, lies a huge challenge: how best to manage the global economic adjustment.

In his foreword to the new World Economic Outlook, Olivier Blanchard, the IMF’s economic counsellor, states: “Achieving a ‘strong, balanced and sustained world recovery’ – to quote from the goal set in Pittsburgh by the G20 – was never going to be easy?.?.?.?It requires two fundamental and difficult economic rebalancing acts.”

The first is internal rebalancing – a return to reliance on private demand in advanced countries and retrenchment of the fiscal deficits that opened in the crisis. The second is external rebalancing – greater reliance on net exports by the US and some other advanced countries and on domestic demand by some emerging countries, notably China. Unfortunately, concludes, Professor Blanchard, “these two rebalancing acts are taking place too slowly”.
