The internationalization of the banking sector presumes the investment of banks operating through their representative offices abroad. Banks are transferred to TNB if their subsidiaries are operating abroad and enabling them to take a dominant position in the global banking market.

Internationalisation of banks refers to the process by which banks expand their operations beyond their home countries to serve global markets. This can involve opening branches, subsidiaries, or representative offices in foreign nations, as well as offering cross-border financial services. The goal is to access new customers, diversify income sources, and take advantage of international growth opportunities. Internationalisation also helps banks support multinational clients and participate in global trade and investment flows. It increases competition and promotes financial innovation but also exposes banks to additional risks such as currency fluctuations, regulatory challenges, and geopolitical instability. Overall, internationalisation allows banks to become global players in the financial system, contributing to the integration of world economies.
