That, as I say, was four years ago. The unsustainable has been sustained a while longer. And there is no point in denying that this might go on for another four years, or more. That is quite possible. Timing the ends of episodes like this one is notoriously difficult. But it would be a grave error to believe that the past four years have refuted that earlier analysis. In fact, those earlier fears are better grounded now than before. Massive extra debts have accumulated, the willingness of foreigners to continue to lend to America is visibly under strain, and in some ways (overinflated housing prices and the galloping cost of oil, to name but two), the economy is more vulnerable to economic stresses than it was back then.
So it is important not to be reassured by the mere familiarity of the issue. The problem is all too real: Imbalances in global trade and finance are exposing the United States and the world to some serious economic hazards. The changes at the IMF indicate at least that governments are recognizing the issue. If they are not yet doing anything meaningful to address it, at least they see that they ought to pretend to. That is progress, of a kind.
The IMF's new mandate is to oversee a mediated negotiation among the countries with the biggest external imbalances—on one side, America with its colossal deficit; on the other, with their offsetting surpluses, China, Germany, Japan, and the main oil-exporting nations. First, the IMF will prepare and publish an analysis of the issues. (Publication is important; it gives the IMF a bit more clout than it would otherwise have.)
We already know what it will say, because the IMF and many others have been saying it for so long. Still, the new mandate is a license to speak more frankly.
Once the analysis is done, officials will aim to reach agreements with the governments concerned on the policies needed to put things right. No surprises there, either.
There will be two main points. The United States will be advised to increase its domestic savings, preferably by cutting the government's budget deficit (this will discourage imports and reduce the need for foreign capital). China will be advised to let its currency appreciate (thereby causing the dollar to be devalued, further reducing American imports and making the country's exports more competitive).
There will be recommendations for other countries too, partly to spread the blame around and show that everybody is chipping in. The European Union, for instance, will be told to stand ready to stimulate demand as curbs on America's budget deficit take hold. The idea there is to keep global demand roughly steady. As demand in America is trimmed back, it needs to be stimulated elsewhere—otherwise, by trying to forestall a global recession, governments might start one instead.
