Primary credit. A Federal Reserve Bank may extend primary credit on a very short-term basis, usually overnight, as a backup source of funding to a depository institution that is in generally sound financial condition in the judgment of the Reserve Bank. Such primary credit ordinarily is extended with minimal administrative burden on the borrower. A Federal Reserve Bank also may extend primary credit with maturities up to a few weeks as a backup source of funding to a depository institution if, in the judgment of the Reserve Bank, the depository institution is in generally sound financial condition and cannot obtain such credit in the market on reasonable terms. Credit extended under the primary credit program is granted at the primary credit rate.
