The global financial system is undergoing a period of increasing fragmentation as payment and settlement infrastructures become politicised and alternative systems emerge. Platforms such as SWIFT and Euroclear remain central to cross-border finance, yet their use in sanction enforcement has encouraged the development of parallel payment and settlement arrangements, particularly among BRICS economies. This paper examines the implications of global payment system fragmentation for Cyprus, a small open economy and euro-area financial centre. Rather than focusing on direct exclusion or adoption of alternative systems, the analysis highlights indirect transmission channels, including confidence effects, compliance costs, capital flow volatility, and reputational risk. A conceptual framework is developed to explain how infrastructure fragmentation affects rule-taking economies, followed by a scenario analysis illustrating potential outcomes under different fragmentation trajectories. The results suggest that even under managed coexistence, fragmentation increases operational complexity and regulatory pressures for small financial centres. More severe fragmentation scenarios could amplify funding risks and challenge financial intermediation models. The paper concludes with policy recommendations for Cyprus and the European Union, emphasising regulatory alignment, compliance capacity, and infrastructure governance as key tools for managing fragmentation-related risks.
