Fast facts

  • The BIS announced on Wednesday a new “Project Mariana” that will study the use of automated market makers (AMMs) to automate foreign exchange markets and settlement, and potentially improve cross-border payments.
  • An AMM is a type of smart contract that adopts liquidity pools to transfer digital assets automatically, as opposed to the traditional process of matching buyers and sellers, according to the BIS.
  • “As DeFi and its applications have the potential to become systemically important parts of the financial ecosystem, central banks need to understand their impact for cross-border payments,” the BIS said.
  • The BIS explained that the concept of such AMM protocols could form the basis for a new generation of financial infrastructures that facilitate cross-border exchanges of CBDCs.
  • The BIS last week published a report on its mBridge pilot project examining CBDC cross-border payments in collaboration with the central banks of Thailand, China, the United Arab Emirates and Hong Kong.
