The incumbent superpower has blinked in its confrontation with the rising one: the US Treasury has decided to postpone a report due by April 15 on whether China is an exchange-rate manipulator. Since a programme of multilateral and bilateral consultations is under way, it was right to give these discussions a chance before taking any action.
Is China a currency manipulator? Yes. China has intervened on a gigantic scale to keep its exchange rate down. Between January 2000 and the end of last year, China's foreign currency reserves rose by $2,240bn; after July 2008, when the renminbi's gradual appreciation against the dollar – begun three years earlier – halted, reserves rose by $600bn (see chart); and reserves are now close to 50 per cent of gross domestic product. Finally, a massive effort has been aimed at curbing the inflationary effects of intervention.
Thus, China has controlled the appreciation of both nominal and real exchange rates. This surely is currency manipulation. It is also protectionist, being equivalent to a uniform tariff and export subsidy. Premier Wen Jiabao has protested against “depreciating one's own currency, and attempting to pressure others to appreciate, for the purpose of increasing exports. In my view, that is protectionism”. The Chinese pot is calling the US kettle black.
