2003. évi XXIII. törvény a fizetési, illetve értékpapír-elszámolási rendszerekben történõ teljesítés véglegességérõl

This law establishes rules to ensure that payments and securities transfers are irrevocable and unconditional once they reach a certain stage of processing. This prevents systemic risk by ensuring that a participant's insolvency does not cause a chain reaction of failed transactions across the financial network. This primarily affects banks, financial institutions, and payment system operators in Hungary, providing legal certainty for high-value payment and securities settlement systems.
