Spain is set to fully implement two significant cryptocurrency regulatory frameworks in 2026: the EU's Markets in Crypto-Assets Regulation (MiCA) and the Directive on Administrative Cooperation (DAC8). MiCA will take full effect on July 1, 2026, mandating that all crypto service providers obtain full authorization to continue operations. Meanwhile, DAC8 will be enforced from January 1, 2026, requiring exchanges to report user transactions, balances, and fund flows to EU tax authorities.
