The Export-Import Bank of the United States (Ex-Im Bank), an independent federal government agency, is the official export credit agency of the United States. It helps finance American exports of manufactured goods and services, with the objective of contributing to the employment of U.S. workers, primarily in circumstances when alternative financing is not available. Ex-Im Bank also may assist U.S. exporters to meet foreign, officially sponsored, export credit competition. Ex-Im Bank's main programs are direct loans, loan guarantees, working capital guarantees, and export credit insurance. Ex-Im Bank transactions are backed by the full faith and credit of the U.S. government. The Bank operates under a renewable charter, the Export-Import Bank Act of 1945, which requires that all of the Bank's financing have a reasonable assurance of repayment and directs the Bank to supplement, and to not compete with, private capital.
