Why Financial Innovation Must Challenge Legacy Architecture
- •Professor Wenxin Du challenged claims surrounding financial innovation at the Jackson Hole Economic Policy Symposium by critiquing popular propositions about payments and stablecoins.
- •The critique evaluates new technology within a static financial architecture, assuming current systems are constraints rather than structures that need redesigning for the intelligence economy.
- •Incumbent financial systems possess massive scale and liquidity advantages, but historical technological shifts show that innovation is almost always marginal before it scales.
- •Payment infrastructure has evolved into geopolitical infrastructure where resilience, sovereignty, and programmability hold immense value beyond mere transaction costs.
- •Central bankers must ask how economic architecture should change because of technology, ensuring institutions evolve to remain relevant to the modern world.
Key Questions Answered
At the 2026 Jackson Hole Economic Policy Symposium, Professor Wenxin Du questioned whether 24/7 atomic real-time gross settlement is the future of wholesale payments, whether retail payment friction is primarily a legacy-technology issue, and whether stablecoins are inherently efficient for cross-border payments.
Systems like CLS achieve high liquidity savings, settling approximately $7.9 trillion of FX transactions daily while requiring only about $300 billion in actual funding, which results in a netting efficiency of around 96 per cent.
Project mBridge was expressly designed to explore instant cross-border settlement through a multi-CBDC architecture, progressing toward meaningful transaction volumes alongside expansions of cross-border e-CNY infrastructure by 2026.
