Definition ∞ PSD2 Overlap describes the intersection or common ground between the European Union’s Revised Payment Services Directive (PSD2) and other regulatory frameworks or emerging financial technologies. This term identifies situations where PSD2 principles or requirements may apply to or conflict with new digital payment methods or blockchain-based services. It highlights areas of regulatory congruence or divergence.
Context ∞ The PSD2 overlap with decentralized finance (DeFi) and crypto payments presents a complex regulatory challenge. Authorities are determining how to apply existing directives to non-traditional financial intermediaries and protocols. Ongoing discussions focus on clarifying jurisdictional boundaries and ensuring consistent consumer protection and anti-money laundering measures across these evolving sectors.
