Are Offshore RMB Arrangements the Basis for a Long-term Exchange Rate System without Convertibility?

This paper discusses China's relatively new structure of dual onshore and offshore RMB markets. Its distinguishing feature is both offshore trading at exchange rates that are market determined and onshore trading at exchange rates anchored at the official spot rate with capital account inconvertibility. We note that thus far the CNH and CNY spot rates have largely tracked each other, suggesting that the shadow price on the convertibility constraint onshore and also the offshore diversification benefit is close to zero. However, this could change in the future. We discuss the potential for the offshore RMB market to grow with trade settlement and bilateral swap arrangements in RMB, which would provide a big enough pool of liquidity for the RMB to become a vehicle currency and reserve currency. These potential developments will be restrained by onshore inconvertibility, but moving to convertibility seemingly implies major change in China's financial structure and the offshore RMB arrangements are only a small first step along this path. Crucial in this evolution of arrangements will be future Chinese growth performance and the relative attractiveness of onshore inconvertible but offshore marketable RMB relative to the debt laden and slow growth currencies of the USA, the EU and Japan.
