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 two years, the renminbi 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 renminbi bloc, because the renminbi 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 renminbi than with the dollar, with the average value of the CMC relative to the renminbi being 40 percent greater than that for the dollar.
We find that co-movements with a reference currency, especially for the renminbi, are associated with trade integration. We draw some lessons for the prospects for the renminbi bloc to move beyond Asia based on a comparison of the renminbi’s situation today and that of the Japanese yen in the early 1990s. If trade were the sole driver, a more global renminbi bloc could emerge by the mid-2030s but complementary reforms of the financial and external sector could considerably expedite the process.
