Fedwire Payments for NASA

The Federal Reserve Banks provide the Fedwire Funds Service, a real-time gross settlement system that enables participants to initiate funds transfer that are immediate, final, and irrevocable once processed. Depository institutions and certain other financial institutions that hold an account with a Federal Reserve Bank are eligible to participate in the Fedwire Funds Services. There are approximately 7,300 participants who make Fedwire funds transfers. The Fedwire Funds Service is generally used to make large-value, time-critical payments. International and Domestic financial institutions can use Fedwire to send a wire transfer in United States dollars directly to the bank to the United States Treasury, which then forwards the payment to NASA.

The Fedwire Funds Service is a credit transfer service. Participants originate funds transfers by instructing a Federal Reserve Bank to debit funds from its own account and credit funds to the account of another participant. Participants may originate funds transfers online, by initiating a secure electronic message, or off line, via telephone procedures.

The Fedwire Funds Service business day begins at 9:00 p.m. Eastern Time (ET) on the preceding calendar day and ends at 6:30 p.m. ET, Monday through Friday, excluding designated holidays. For example, the Fedwire Funds Service opens for Monday at 9:00 p.m. on the preceding Sunday. The deadline for initiating transfers for the benefit of a third party (such as a bank’s customer) is 6:00 p.m. ET each business day. Under certain circumstances, Fedwire Funds Service operating hours may be extended by the Federal Reserve Banks.

SWIFT Payment

Society for Worldwide Interbank Financial Telecommunication (SWIFT) payment is an interbank communications system in which financial institutions worldwide can send and receive information about financial transactions in a secure, standardized and reliable environment. SWIFT does not facilitate funds transfer; rather, it sends payment orders, which must be settled by correspondent accounts that the institutions have with each other. 
Each financial institution, to exchange banking transactions, must have a banking relationship by either being a bank or affiliating itself with one or more. SWIFT is linked to more than 9,000 financial institutions in 209 countries and territories. For payments to NASA, the SWIFT message directs funds to a United States Treasury account, which then references and forwards the payment to a NASA Center. Please view the instructions by accessing SWIFT Payment Instructions.
Note: NASA does not charge the SWIFT fee.
