Ravi Menon, Director General of the Monetary Authority of Singapore, pointed out that tokenization technology can solve many problems of cross-border payments, and central banks should use current research and future cooperation to solve the biggest problem of cross-border payments, that is, settlement barriers. Ravi Menon said that the use of tokenization technology will make payments smoother, but there must be a sound regulatory framework, through the implantation of smart contracts, regulatory requirements and other rules can be put on the blockchain, because international regulation should be synchronized, so multiple central banks should cooperate to study the same framework. According to Erik Thedéen, president of the Riksbank, the Riksbank will be ready to connect to Europe in cross-border payments in the future, but as a smaller export-oriented economy, it will not become a leading region.
