The United States promotes the "Stablecoin Act" aimed at incorporating stablecoins into the statutory regulatory framework, requiring issuing institutions to hold reserve assets that correspond to the issuance volume, and to undergo regular audits and supervision. This legislation is expected to reshape the cryptocurrency industry ecosystem and bring significant changes to the overall market. As regulations are implemented, compliance costs for businesses will rise, which may be difficult for small and medium issuers to bear, leading to some exiting the market. Large stablecoins like USDC are expected to further strengthen, indicating a clear trend of industry concentration. At the same time, a clear regulatory environment helps boost investment confidence, reduce risk events, and promote the integration of traditional finance and stablecoins. However, the decentralized finance sector (DeFi) may be restricted as a result, and some algorithmically designed stablecoins may face regulatory pressure. The market may experience fluctuations in the short term, but in the long run, it will help promote the healthy development of the entire industry, although it may also suppress technological innovation and the realization of decentralization concepts.
