The Export-Import Bank’s charter is set to expire Tuesday, meaning the 81-year-old agency is on course to be eliminated, at least temporarily.

The bank, the official export credit agency of the federal government, has been called a form of “corporate welfare” and engine of “cronyism” by opponents. Supporters claim the bank helps small businesses in the U.S. compete globally.

Although the charter will expire, supportive lawmakers may attempt to revive it in the future if an amendment concerning the bank is added to a must-pass bill, such as legislation supporting the Highway Trust Fund. With the bank’s ultimate fate still unclear, here are the current presidential candidate’s positions on renewing Ex-Im.
