According to Reuters on August 2nd, the cryptocurrency craze, led by stablecoins, is exacerbating uncertainty within the US credit card duopoly. In recent earnings calls, Visa and Mastercard executives, facing new legislative developments that could accelerate the adoption of stablecoins for the first time, generally downplayed the potential threat posed by dollar-pegged digital currencies to their payment networks. While both companies have provided some comfort to the market with their stable profits and strong valuations, the surge in stablecoin operator Circle Internet Group's market capitalization, exceeding $40 billion, reveals diverging expectations in the capital market for changes in the payments sector, making it difficult for both groups of investors to maintain a balanced view.
