The US Congress has enacted the 'Guidance and Establishment of the US Stablecoin National Innovation Act,' signed into law by presidential executive order. This legislation aims to enhance the US's influence in the crypto economy by creating a 'Dollar-Stablecoin-Crypto Asset' cycle, potentially reshaping global capital flows and international monetary rules. The act requires stablecoin issuers to maintain reserves in US cash or short-term government bonds, which could increase demand for US debt. With the global stablecoin market cap exceeding $270 billion and transaction volumes over $30 trillion, the act designates stablecoins as legal payment tools, impacting international financial governance.
