TL;DR

This paper examines how geopolitical tensions, such as trade wars and sanctions, are prompting countries to shift towards alternative financial networks, leading to increased regional fragmentation in global finance.

Contribution

It introduces a dynamic theoretical model explaining payment system migration driven by sanctions, investment, and network effects, supported by empirical data from multiple countries.

Findings

Countries are increasingly adopting alternative financial networks.

Financial fragmentation is rising due to geopolitical tensions.

International institutions can play a role in mitigating systemic risks.

Abstract

Global financial systems are undergoing strategic shifts as geopolitical tensions reshape international trade and payments. The United States (US)-China trade war, sanctions regimes, and rising concerns over the weaponization of financial infrastructures like SWIFT have led countries to seek alternative networks, including China's CIPS and emerging cross-border CBDCs. This letter presents a dynamic theoretical framework where sanction risks, investment choices, and network effects drive payment system migration. Empirical evidence from Russia, Saudi Arabia, India, and Argentina supports the model. Policy implications point toward increasing financial fragmentation, with critical roles for international institutions to mitigate systemic risks. The future of finance may be less global and more regionally fragmented, influenced heavily by political considerations.
