The correlation maximization of the RMB/USD and the basket currency index may determine the weight and quantity of the basket currency. The currency basket indicates that the weight of the USD is highest, whereas that of the GB Pound is the lowest. Our currency basket has a high linear dependence on that of the central bank. We found that the RMB/USD and currency basket indices have a long-term co-integration relationship according to the optimal currency weights. The results of the error-correcting model manifest as the RMB/USD exchange rate deviates from the long-term equilibrium level, wherein 76.3% will be corrected. This paper checks the prediction capacity, which indicates the good fit of the model. By using the Granger causality test the findings show that the People＇s Bank of China adjusts the RMB/USD exchange rate with reference to the currency basket.展开更多

We find the following stylized facts： the value of the RAIB became stable after the reform; the weight of the US dollar remained high in the basket, while other currencies remained statistically significant; and the floating band gradually increased to lO percent during 2005-2008, and then greatly narrowed from the late summer of 2008 under the assumption of a yearly resetting interval. We find that the foreign exchange market pressure increased from 2005 to 2008. A possible reason is that the weight of the US dollar in the basket was slightly lower than the share of the US dollar in total transactions on the Chinese foreign exchange market. Therefore, it is reasonable for China to adopt a dollar peg exchange rate regime.展开更多

Market interventions backed by huge foreign exchange reserves and capital controls are not sufficient to eliminate the expectations of devaluation. Creating a market-based and flexible RMB exchange rate regime holds the key to the elimination of devaluation expectations. The present paper compares the pros and cons of severaI policy options, and proposes to introduce, as a transition to free floating, a new exchange rate regime pegged to a currency basket with a wide band. The new regime should be able to give the RMB exchange rate enough flexibility to eliminate devaluation expectations as well as prevent excessive overshooting. To ensure a smooth transition, the new regime needs to be supported by controlling cross-border capital flOWS.展开更多

Reforming the exchange rate formation mechanism is a complex engineering project influenced by numerous factors such as the economic development mode,industrial structure,basic economic system,market system condition,financial and macroeconomic policy system as well as the new advantages arising from opening-up initiatives.Since 2005,China has achieved substantial success in reforming the exchange rate formation mechanism but still faces a plethora of issues.To address these issues,China should strengthen the role of the market in the exchange rate formation process and gradually push for the free convertibility of the renminbi under the capital account.Amidst the raging global financial crisis,China should further adapt to the diversification of the international monetary system and aggressively proceed with renminbi regionalization and internationalization.展开更多
