Spain's financial regulator, CNMV, has granted a MiCA license to Renta 4 Banco, making it the fourth Spanish bank authorized to offer cryptocurrency trading, custody, and transfer services. This follows similar approvals for BBVA, Cecabank, and Openbank. The MiCA passport mechanism has also enabled EU institutions like Commerzbank, CACEIS, and Société Générale to operate crypto businesses in Spain. Currently, 54 registered crypto service providers operate in Spain, with many hailing from other EU member states, highlighting Spain's rapid advancement in crypto regulation.
