In some cases, the clearing corporation may assume significant counterparty, financial, or risk management responsibilities for the clearing system.
Also known as a Clearinghouse.
Clearing Account –

Confirmation –
The process in which the terms of a trade are verified either by market participants directly or by some central entity.
Correspondent Bank –
A bank that holds deposits for other banks and performs services, such as check clearing. The deposit balance is a form of payment for services.

Counterparty –

Default –
Failure to complete a funds or securities transfer according to its terms for reasons that are not technical or temporary, usually as a result of bankruptcy.
Delivery-vs-Payments system (DVP) –
A system that ensures that the final transfer of one asset will simultaneously occur if, and only if, the final transfer of another asset (or other assets) occurs.
Depository –
Facility for holding securities in either a certified or an uncertified (dematerialized) form. Allows securities transfers through book-entry. Depositories may also offer funds accounts and permit funds transfers as a means of payment. Depositories may be privately or publicly operated.

Finality –
An irrevocable and unconditional transfer of payment which occurs during settlement.

Foreign Exchange Settlement Risk (a.k.a. Herstatt Risk) –
The potential loss of principal associated with settling transactions sequentially instead of simultaneously.
Hybrid Settlement System –
A combination of a real-time gross settlement system and a multilateral net settlement system. Some deferred net settlement systems have incorporated mechanisms for making irrevocable and unconditional funds transfers during the day rather than only at the end of the day. In some cases this has resulted in hybrid systems which combine features, including risk control measures, of gross and net settlement systems.
Large-Value Transfer System –
A type of wholesale payment system used primarily by financial institutions in which large values of funds are transferred between parties. Fedwire and CHIPS are the two large-value transfer systems in the U.S.
Multilateral Netting –
Multilateral netting is an arrangement among three or more parties to net their obligations. In settlement systems of this type transfers are irrevocable, but are only final after the completion of end-of-day-settlement.
Net Debit Cap –
The maximum dollar amount of daylight overdrafts an institution is permitted to incur in its Federal Reserve account. The exact dollar amount is a multiple – determined by the Federal Reserve – of an institution's capital. Under current policy, institutions are subject to two caps: a daily cap and a 2-week average cap. Net debit caps help reduce the credit risk to the Federal Reserve and taxpayers by limiting losses should an institution fail. In April 1994, as a supplement to the existing net debit cap policy, Federal Reserve Banks began charging fees to depository institutions for average daylight overdrafts in deposit accounts with the Federal Reserve.
Net Settlement Systems –
(Also referred to as Deferred Net Settlement Systems). A category of payments system. A system in which banks continually send payment instructions over a period of time, with final transfer occurring at the end of the processing cycle. During the period, a record is kept of net debits and credits.
Payment –
A transfer of value.
Payment System –
The mechanism – the rules, institutions, people, markets, and agreements – that make the exchange of payments possible.
Payment vs. Payment –

Point-of-Sale (POS) Network –
A network of banks, debit cardholders, and merchants that permit consumers to electronically make direct payment at the place of purchase. The funds transfer directly from the account of the cardholder to the account of the merchant.
Real-Time Gross Settlement (RTGS) System –
A category of payments system. A system is said to operate in real-time if each payment is processed as it is initiated – which provides immediate finality – rather than in batch. This serves to reduce Herstatt Risk. Gross settlement refers to the settlement of each transfer individually rather than netting. Fedwire uses a real-time gross settlement system.
Reserve Account –
A non-interest earning balance that depository institutions maintain with the Federal Reserve Bank or with a correspondent bank to satisfy the Fed's reserve requirements. Reserve account balances play a central role in the exchange of funds between depository institutions.
Reserve Requirements -
The percentage of deposits that a bank or other depository institution may not lend out or invest and must hold either as vault cash or on deposit at a Federal Reserve Bank. Reserve requirements affect the potential of the banking system to create transaction deposits.
Retail Payments –
Small-dollar payments made in the goods and services market.
Securities Settlement System –
The full set of institutional arrangements for confirmation, clearance, and settlement of securities trades and safekeeping of securities.
Settlement –
The final step in the transfer of ownership involving the physical exchange of securities or payment. In a banking transaction, settlement in the process of recording the debit and credit positions of the parties involved in a transfer of funds; in a financial instrument transaction, settlement includes both the transfer of securities by the seller and the payment by the buyer. Settlements can be "gross" or "net." Gross settlement means each transaction is settled individually. Net settlement means that parties exchanging payments will offset mutual obligations to deliver identical items, at a specified time, after which only one net amount of each item is exchanged.
Settlement date –
The date on which the parties to a transaction agree that settlement is to take place.
Smart-Card –
A card-based payment system that stores values for transactions on a computer chip instead of a magnetic stripe. As the card is used for transactions, the amounts are subtracted from a balance on the chip. As the balance approaches zero, the chip can be "reloaded" through a number of methods. These cards are often used in closed-systems for specific types of purchases but do not have to be so restricted. The chip also allows the owner to keep a variety of information with them at all times.
Wholesale Payments –
Large-value payments used primarily in the financial markets.
