The paper considers the optimal transition path for China's exchange rate regime. How can China successfully make the shift from the current dollar peg regime to a more desirable regime, whether a basket peg or a floating regime? To answer this question, we develop a dynamic small open economy general equilibrium model. We construct four transition policies based on a basket peg or a floating regime and compare the welfare gains of these policies relative to maintaining the dollar peg regime. Two main results are derived from the quantitative analysis using Chinese data from 1999Q1 to 2010Q4. First, following a gradual adjustment to a basket peg regime is the most appropriate path for China to take, with minimal welfare losses associated with the shift in the exchange rate regime. Second, a sudden shift to the basket peg is the second best solution, and is superior to a sudden shift to floating because the monetary authority can efficiently determine optimal weights to attach to currencies in the basket to achieve policy goals once they adopt a basket peg regime. Eichengreen (2006), have pointed out the shortcomings of the de facto peg to the dollar and advocate the benefits of greater flexibility in the exchange rate under a floating regime to help the Chinese monetary authority tailor monetary conditions to domestic needs. In this context, the immediate removal of capital restrictions and gradual widening of the band of the exchange rate have been proposed.Others, such as Ito et al. (1998), Kawai (2004) and Yoshino et al. (2004a, b) propose a transition to a basket peg regime, which would overcome drawbacks of the dollar peg regime, with the economy currently negatively influenced by fluctuations in exogenous exchange rates: for instance, the dollar-yen rate. 1,2 For a country like China, which has close economic relationships with multiple partners, including the European Union, Japan and the USA, exchange rate stabilization using a basket comprising these currencies would be beneficial because it would remove the problem of large fluctuations in exchange rates. 3Contrary to the two lines of thought outlined above, McKinnon and Schnabl (2014) emphasize the importance of stabilizing the renminbi-US dollar exchange rate for the country's international competitiveness.Regardless of whether a basket peg or floating regime is considered to be appropriate in the long term, there remains a major question that has not been addressed in the literature on exchange rate regimes. How can China successfully transition to a desirable regime, whether a basket peg or a floating regime, from the current de facto peg to the dollar regime? Needless to say, a departure from the status quo would entail substantial costs for the monetary authority. Along the transition path toward a basket peg or a floating regime under perfect capital mobility, the monetary authority would have to remove capital controls and switch policy instruments (basket weight or money supply). To derive the optimal transition policy for China, we develop a ...
