What roles do U.S. banks play in the international marketplace?

"The financial marketplace spans the globe, with money routinely flowing across international borders. U.S. banks play an important role in global business by providing loans to foreign governments and businesses. Multinational corporations need many special banking services, such as foreign-currency exchange and funding for overseas investments. U.S. banks also offer trade-related services, such as global cash management, that help firms manage their cash flows, improve their payment efficiency, and reduce their exposure to operational risks. Sometimes consumers in other nations have a need for banking services that banks in their own countries don’t provide. Therefore, large banks often look beyond their national borders for profitable banking opportunities. Many U.S. banks have expanded into overseas markets by opening offices in Europe, Latin America, and Asia. They often provide better customer service than local banks and have access to more sources of funding. Citibank, for example, was the first bank to offer banking by phone and 24-hour-a-day ATM service in Japan."
