币界网报道：On June 13, affected by the legislation of stablecoins and the implementation of retail terminals, the share prices of the U.S. payment sector fell sharply. The U.S. Senate recently passed the GENIUS Act to lower the threshold for the issuance of stablecoins; Shopify and Coinbase piloted USDC settlement on the Base chain, and Walmart and Amazon evaluated issuing their own stablecoins. The stablecoin payment rate is only 0.2%, which is much lower than the traditional 2.5% rate and will subvert the existing payment system. About 55% of Visa and MasterCard's revenue comes from transaction fees. If the penetration rate of stablecoins reaches 10% in 2026, their revenue may decrease by US$1.3 billion. PayPal and Shopify are also under pressure to adjust their business models, and Shopify's gross profit margin may be compressed by 150bp. The market is closely watching the progress of legislation, the stablecoin trends of retail giants, and the on-chain settlement strategies of traditional payment companies.
