Collateral Programs

Government agencies must ensure the security of public money on deposit at depository institutions, such as a bank. A bank must pledge collateral (see Treasury’s lists of acceptable collateral) to secure these funds.

This page contains information and links to the rules governing Treasury’s Fiscal Service collateral programs, lists of acceptable collateral, and collateral margins tables.
