Federal Reserve Governor Lisa Cook announced that the scale of tokenized assets in the United States has doubled over the past year to approximately $25 billion. Cook emphasized that tokenization can enhance the efficiency of cross-border payments, collateral management, and liquidity, while enabling automated settlements and more flexible financial transaction structures through smart contracts. She noted that tokenization is not expected to replace traditional financial infrastructure but could integrate with existing market systems to improve financial system efficiency. Cook also cautioned about potential financial stability issues, including liquidity risks, the interconnectedness of financial systems, and vulnerabilities such as network attacks and smart contract flaws within the DeFi ecosystem.
