Spain's payment sector is rapidly evolving as cryptocurrencies and Open Finance drive technological advancements. Cryptocurrencies are facilitating secure, near-instant transactions, while Open Finance is improving integration and efficiency across financial services. New crypto projects are being developed to integrate with existing payment systems, offering enhanced security and faster settlements. The EU's Immediate Payments Regulation is set to enable transactions in under 10 seconds, further accelerating the sector's transformation. Open Finance is expanding beyond traditional banking to include insurance and wealth management, potentially increasing operational efficiency by up to 30%. However, cybersecurity remains a critical concern, with regulations like DORA enforcing strict standards. AI is increasingly used in risk management and automation, while the future of a digital euro continues to be a topic of debate among experts.
