The United States promotes the "Stablecoin Act," which aims to incorporate stablecoins into the legal regulatory system, requiring issuing entities to hold reserve assets corresponding to the issuance volume and to undergo regular audits and supervision. This act is expected to reshape the cryptocurrency industry ecosystem and bring significant changes to the overall market. As regulations come into effect, the compliance costs for businesses will increase, making it difficult for small and medium-sized issuers to bear, which may lead to some exiting the market. Large stablecoins like USDC are expected to further strengthen, with a clear trend toward industry concentration. At the same time, a clear regulatory environment helps boost investor confidence, reduce risk events, and promote the integration of traditional finance and stablecoins. However, the decentralized finance (DeFi) sector may be restricted as a result, and some algorithmically designed stablecoins may face policy pressure. The short-term market may experience fluctuations, but in the long run, it is conducive to promoting the healthy development of the entire industry, although it may also suppress technological innovation and the realization of decentralized ideals.
