31 CFR § 356.17 - How and when do I pay for securities awarded in an auction?
(a) General. By bidding in an auction, you agree to pay the settlement amount for any securities awarded to you. (See § 356.25.) For notes and bonds, the settlement amount may include a premium amount, accrued interest, and, for inflation-protected securities, an inflation adjustment.
(b) Securities held directly with Treasury. You must pay for your awarded securities by a debit entry to a deposit account that you are authorized to debit or by using the redemption proceeds of your certificate of indebtedness. Payment by debit entry occurs on the settlement date for the actual settlement amount due. (See § 356.25.)
(c) Commercial book-entry system. Unless you make other provisions, payment of the settlement amount must be by charge to the funds account of a depository institution at a Federal Reserve Bank.
(1) A submitter that does not have a funds account at a Federal Reserve Bank or that chooses not to pay by charge to its own funds account must have an approved autocharge agreement on file with us before submitting any bids. Any depository institution whose funds account will be charged under an autocharge agreement will receive advance notice from us of the total par amount of, and price to be charged for, securities awarded as a result of the submitter's bids.
(2) A submitter that is a member of a clearing corporation may instruct that delivery and payment be made through the clearing corporation for securities awarded to the submitter for its own account. To do this, the following requirements must be met prior to submitting any bids:
(i) We must have acknowledged and have on file an autocharge agreement between the clearing corporation and a depository institution. By entering into such an agreement, the clearing corporation authorizes us to provide aggregate par and price information to the depository institution whose funds account will be charged under the agreement. The clearing corporation is responsible for remitting payment for auction awards of the clearing corporation member.
(ii) We must have acknowledged and have on file a delivery and payment agreement between the submitter and the clearing corporation. By entering into such an agreement, the submitter authorizes us to provide award and payment information to the clearing corporation.
