Despite worldwide concerns about the US dollar, the Chinese renminbi is not yet ready to be a serious contender for leading international currency status. This Policy Brief examines three of the most important Chinese approaches to increasing the renminbi’s role as an international settlement currency: promote bilateral swap agreements between the People’s Bank of China and other central banks; create international payment systems that do not involve the dollar, most notably the Cross-Border Interbank Payment System; and develop a central bank digital currency for alternative payment infrastructures.
The authors find that Beijing’s efforts fall short of posing a systemic challenge to the dollar or to infrastructures like SWIFT. Nevertheless, these approaches have enabled China to use its currency for bilateral foreign policy. US and European policymakers should consider countering or attenuating these efforts, even though they have had limited success in increasing renminbi usage.
