Core Focus: The concept of monetary sovereignty in the digital age, the geopolitical dimensions of CBDC development, and the potential for CBDCs to reshape the international monetary system.

In-Depth Notes:
CBDCs are not merely a payment innovation; they are instruments of monetary sovereignty and instruments of geo-economic competition. Across the globe, central banks are either actively exploring or are already engaged in developing CBDCs, and these initiatives are widely seen to be motivated by geo-economic dynamics .

Monetary Sovereignty in the Digital Age:
Monetary sovereignty—the ability of a state to control its currency and monetary policy—is the central concern driving CBDC development. As private digital currencies and foreign CBDCs proliferate, national currencies face unprecedented competition. Smaller economies may face the risk of CBDCs from larger countries crowding out national digital money, leading to “digital dollarisation” or “yuanisation” . This could reduce the effectiveness of monetary policy as central bank interest rate settings become less relevant. A CBDC ensures that the national currency remains the primary medium of exchange in the digital sphere, preventing a shift to foreign private digital currencies and CBDC . For the European Central Bank, the digital euro is seen as an instrument to strengthen the singleness of the euro in a digitalising economy and to protect European payment autonomy .

CBDCs as Instruments of Geopolitics:
CBDCs are increasingly viewed as geopolitical instruments. They have the potential to facilitate international transactions that no longer rely on the use of the US dollar and therefore on clearing institutions under US jurisdiction . As such, they could become instruments to evade the reach of Western sanctions and to shield domestic and cross-border transactions from foreign interference . The mBridge project, involving China, Hong Kong, the United Arab Emirates, and Thailand, is an example of how multi-CBDC arrangements could provide an alternative to the dollar-centric correspondent banking system . These initiatives reflect a growing recognition that payment infrastructure, standards, and instruments are strategic assets of national and supranational sovereignty that states can no longer leave entirely in private or foreign hands .

The Future of the International Monetary System:
The future of the international monetary system is at stake. CBDCs could reinforce the dominance of the US dollar if US dollar-pegged stablecoins proliferate globally. Alternatively, they could challenge that dominance if multi-CBDC platforms provide viable alternatives to dollar-based payment systems. The geopolitical competition between the United States and China is being waged in part through digital currency policy: the US is promoting private dollar-pegged stablecoins as an extension of dollar dominance, while China is building a parallel financial system where Chinese fintechs are allowed to issue stablecoins from Hong Kong . The choices made by central banks, regulators, and governments over the coming years will determine whether the international monetary system remains anchored in the dollar, becomes more multipolar, or fragments into competing digital currency blocs.
