Stablecoins processed an unprecedented $33 trillion in transactions in 2025, nearly doubling Visa's $16.7 trillion volume. This milestone underscores stablecoins' growing significance in global finance, as they now represent over 1% of all US dollars in circulation. The market has expanded from $5 billion in 2020 to $313 billion in March 2026, with transaction volume increasing by 72% year-on-year. Stablecoin issuers have become major holders of US Treasury bills, collectively holding $155 billion, surpassing countries like Germany and Saudi Arabia. Tether and Circle are leading with $127 billion and $25 billion, respectively. The GENIUS Act, enacted in July 2025, has been pivotal, mandating 1:1 reserve backing and allowing banks to issue stablecoins, which has encouraged institutional engagement. Major payment networks like Visa, Stripe, and Mastercard are integrating stablecoins into their operations, with Mastercard acquiring BVNK for $1.8 billion. The stablecoin market is projected to reach $2 to $4 trillion by 2030, driven by increasing adoption in countries with unstable local currencies, offering a stable alternative to traditional banking.
