The Renminbi Bloc is Here: Asia Down, Rest of the World to Go?1)

Abstract: A country’s rise to economic dominance tends to be accompanied by its currency becoming a reference point, with other currencies tracking it implicitly or explicitly. For a sample comprising emerging market economies, we show that in the last 3 years, the renminbi (RMB) has increasingly become a reference currency which we define as one which exhibits a high degree of co-movement (CMC) with other currencies. In East Asia, there is already a RMB bloc, because the RMB has become the dominant reference currency, eclipsing the dollar, which is a historic development. In this region, 7 currencies out of 10 co-move more closely with the RMB than with the dollar, with the average value of the CMC relative to the RMB being about 60% greater than that for the dollar. We find that co-movements with a reference currency, especially for the RMB, are associated with trade integration. We draw some lessons for the prospects for the RMB bloc to move beyond Asia based on a comparison of the RMB’s situation today and that of the Japanese yen in the early 1990s. If trade were the sole driver, a more global RMB bloc could emerge by the mid-2030s but complementary reforms of the financial and external sector could considerably expedite the process.
