International banking is the academic field and research domain concerned with the cross-border financial activities and operations of banking institutions. This encompasses the systematic investigation of international financial flows, foreign exchange markets, global payment systems, the diverse regulatory and legal environments governing banking across national borders, and the strategic management and risk profiles inherent in multinational banking. Characterized by its multi-jurisdictional scope and exposure to varied economic, political, and currency risks, its significance lies in analyzing the mechanisms facilitating global trade and investment, international capital allocation, and understanding systemic risks within the global financial architecture.
