46 U.S.C. § 53716 — Deposit fund

(a) In General. There's a deposit fund in the Treasury for this section. The Secretary or Administrator, under an agreement described in (b), may deposit and hold in it cash belonging to an obligor, to serve as collateral for that obligor's guarantee. (b) Agreement. The Secretary or Administrator and the obligor must make a reserve fund or collateral agreement governing deposits, withdrawals, retention, use, and reinvestment of the obligor's cash in the fund. It must include: (1) the terms this section requires; (2) terms giving the U.S. government a security interest in everything deposited; and (3) any other terms the Secretary or Administrator thinks are needed to fully protect the government's interest. (c) Investment. The Secretary or Administrator may invest and reinvest fund money in government obligations maturing in time to meet the agreement's needs. Cash beyond current needs must be kept uninvested, and the Secretary of the Treasury must pay interest on it. (d) Withdrawals. (1) Cash deposited in the fund can't be withdrawn without the Secretary's or Administrator's consent. (2) Subject to (3), the Secretary or Administrator may pay the obligor any income earned on the obligor's deposited cash, following their agreement. (3) The Secretary or Administrator may instead keep and use any or all of the obligor's cash in the fund, and its earnings, to help recover losses if the obligor defaults on an obligation.
