Discount Window Lending: Policy Trade-offs and the 1985 BoNY Computer Failure

On November 21, 1985, the Bank of New York (BoNY) suffered a software failure that left it unable to redeliver securities it had received from other institutions as an intermediary. The result of the failure was that the bank sought and received $22.6 billion in discount window lending from the New York Fed, a record-setting amount. The episode presents a case study for considering when discount window lending and similar interventions are justified as a matter of efficiency, as well as the need for policymakers to take account of possible moral hazard that may lead to inadequate safeguards against failures — whether operational breakdowns or deficient financial strategies.
