According to CriptoNoticias, the Bank of Spain warned in its Spring 2026 Financial Stability Report that widespread adoption of stablecoins could exacerbate domestic currency substitution, increase cross-border financial flows, and amplify the cross-border transmission of shocks from U.S. monetary policy and between different jurisdictions. The report states that the global stablecoin market cap has exceeded $320 billion, with USD stablecoins accounting for 98% to 99%, while EUR stablecoins make up only about 0.2%. The Bank of Spain believes that stablecoins like USDC and USDT, issued across multiple jurisdictions, could pose risks of regulatory fragmentation and challenges in crisis management coordination. https://(wublock123.com)/news/spain-central-bank-warns-stablecoin-adoption-risks-systemic-financial-61184
