Secondary credit is available to depository institutions that are not eligible for primary credit. It is extended on a very short-term basis, typically overnight, at a rate that is above the primary credit rate. Secondary credit is available to meet backup liquidity needs when its use is consistent with a timely return to a reliance on market sources of funding or the orderly resolution of a troubled institution. Secondary credit may not be used to fund an expansion of the borrower's assets. The secondary credit program entails a higher level of Reserve Bank administration and oversight than the primary credit program. A Reserve Bank must have sufficient information about a borrower's financial condition and reasons for borrowing to ensure that an extension of secondary credit would be consistent with the purpose of the facility.
