The next big global financial crisis will emanate from China. That is not a firm prediction. But few countries have avoided crises after financial liberalisation and global integration. Think of the US in the 1930s, Japan and Sweden in the early 1990s, Mexico and South Korea in the later 1990s and the US, UK and much of the eurozone now. Financial crises afflict every kind of country. As Carmen Reinhart of the Peterson Institute for International Economics and Kenneth Rogoff of Harvard have remarked, they are “an equal opportunity menace”. Would China be different? Only if Chinese policymakers retain their caution.

Such caution permeated last week’s report that the People’s Bank of China has recommended accelerated opening up of the Chinese financial system. Given what is at stake, in both China and the world, it is essential to consider the implications. Maybe the world will then do a better job of managing this process than it has done in the past.

This plan was published by Xinhua, the state news agency, not on the PBoC’s web site. Moreover, it was published under the name of Sheng Songcheng, head of the statistics department, not that of the governor or a deputy governor. This must mean that it is more an exercise in kite-flying than a policy. Nevertheless, this was published with the PBoC’s approval and, quite possibly, with that of people much higher up still.
