The Group of Seven industrialized nations will call for transparency and privacy protection as part of a common set of guiding principles created for central bank digital currencies, a draft document showed Monday.

The 13-point rules are expected to be endorsed during a meeting of finance chiefs in Washington on Wednesday, and approval would come at a time when China is taking the lead in the global race to launch a CBDC, which has sparked concerns the development could allow stronger surveillance of its economy and people.

While noting the issuance of such currencies is a "sovereign matter," the document obtained by Kyodo News said that "by setting out a common set of principles, and underscoring the fundamental importance of shared values such as transparency, rule of law and sound economic governance, these principles can guide and inform exploration of retail CBDC in the G-7 and beyond."
