Digital currencies and payment infrastructure are changing how money moves across borders, and the global monetary system is changing with them. CGTN's Guan Xin sits down with Marc Schwartz—chairman and CEO of the Monnaie de Paris, former senior advisor at the French Treasury, and author of The New Currency Wars. They explore the slow but steady shift toward a three-polar currency world, the critical fight for interoperability between CIPS and the digital euro, the hidden mechanics of dollar-backed stablecoins, and why central banks are loading up gold.
