This study assesses the impact of CBDCs development on currency's invoicing capability in international trade. Based on the theories of firms' profit maximization, trade elasticity and sticky prices, this study constructs a model of currency choice for invoicing, and includes CBDC shock as a moderating effect. Utilizing a sample of the top 50 countries, covering the period from 2005 to 2022, this study finds that the development of a country's CBDC significantly amplifies the transmission of bilateral exchange rate changes between exporting country and importing country into changes in traded commodity prices, suggesting an enhanced invoicing power of the country's currency, as well as this effect is even stronger in countries that have piloted CBDC programs. Mechanism tests reveal that the development of CBDC enhances the currency invoicing power by reducing exchange rate volatility and increasing currency liquidity in international foreign exchange market. These effects make it a more attractive choice for international invoicing. Our research may provide insights for policymakers that promoting and accelerating the development of CBDCs can promote the use of national currencies in international trade, as well as improve national currency internationalization.
