The Geography of Dollar Funding of Non-US Banks

Where do non-US banks obtain the funding for the large amount of US dollars they lend? Traditionally, their branches and subsidiaries in the United States were a major source of dollar funding, but the role of these affiliates has declined. Instead, dollars are increasingly raised in the home country. Where dollar funding is raised, however, is distinct from the location of the funding provider, as cross-border liabilities play a large role.
