What is defined as moving money from one country to another?

The correct choice is International Banking, as it specifically pertains to the activities related to transferring funds and financial services across national borders. This area of banking deals with foreign exchange, trade finance, and the financing of international transactions, which are essential for businesses and individuals engaging in cross-border commerce.

International Banking plays a vital role in the global economy, facilitating the movement of money for various purposes such as trade, investment, and personal remittances. By supporting these activities, this type of banking ensures that financial operations can occur smoothly between different currencies and regulatory environments.

In contrast, Retail Banking focuses primarily on providing services to individual consumers, such as savings accounts, personal loans, and mortgages, rather than international transactions. Investment Banking deals with raising capital for corporations, providing advisory services for mergers and acquisitions, and facilitating securities trading, which again does not inherently involve the direct movement of money between countries. Commercial Banking typically serves businesses and provides services like working capital loans and cash management, without the emphasis on international money transfer.
