Green fintech merges sustainable finance with data-intensive innovation, but national translations of EU rules can create regulatory risk. This study examines how such risk manifests in Central Europe and which policy tools mitigate it. We develop a three-dimension framework—regulatory clarity and scope, supervisory consistency, and innovation facilitation—and apply a comparative qualitative design to Hungary, Slovakia, Czechia, and Poland. Using a common EU baseline, we compile coded national snapshots from primary legal texts, supervisory documents, and recent scholarship. Results show material cross-country variation in labelling practice, soft-law use, and testing infrastructure: Hungary combines central-bank green programmes with an innovation hub/sandbox; Slovakia aligns with ESMA and runs hub/sandbox, though the green-fintech pipeline is nascent; Czechia applies a principles-based safe harbour and lacks a national sandbox; and Poland relies on a virtual sandbox and binding interpretations with limited soft law. These choices shape approval timelines, retail penetration, and cross-border portability of green-labelled products. We conclude with a policy toolkit: labelling convergence or explicit safe harbours, a cross-border sandbox federation, ESRS/ESAP-ready proportionate disclosures, consolidation of recurring interpretations into soft law, investment in suptech for green-claims analytics, and inclusion metrics in sandbox selection.

The paper analyzes the banking systems of the Slovak Republic under the influence of the European Union legislation and banking system of the Russian Federation from the perspective of opening the banking sector to foreign capital. A fundamental difference between the given legislations, which is reflected mainly in the recent period, lies in the degree of openness of the banking system to foreign capital. While the banking system of the Slovak Republic under the influence of the European Union law can be considered as highly open banking system to foreign capital, the legislation concerning the Russian banking system is characteristic by legal limitation for foreign capital entry. The analysis of these contradictory tendencies which have common goal – to ensure a stable banking system could bring important knowledge that may help in resolving the issue of stability of the banking system at the global level.
