Retail payments are relatively high-volume, low-value payments. Retail payment methods include cash, checks, debit and credit card, and ACHtransactions. While depository institutions provide cash processing services to retailers and other depository institutions, the Federal Reserve provides cash processing services only to depository institutions and the U.S. government. The Federal Reserve and correspondent banks provide check collection and settlement services. The Federal Reserve and private electronic network operators provide clearance and settlement services for ACH transactions. Private electronic network operators also provide clearance and settlement services for debit card, credit card, and automated teller machine (ATM) transactions. For consumers and retailers, cash transactions are settled instantaneously. However, checks require a more complex settlement process and more time to settle. Depository institutions have several alternative methods for clearing and settling checks. Figure 1 illustrates an example of how a check is settled through direct presentment—when depositary banks present checks directly to the paying bank. In practice, local checks generally settle in 1 business day and nonlocal checks generally settle in 1 to 2 business days. Currently, checks are settled on business days, which do not include weekends, resulting in a delay in the settlement of those checks deposited during the latter part of the week. Credit card and debit card payments also require a complex system to clear and settle transactions. A credit transaction is initiated when a customer’s card number is entered into a card reader, followed by the transaction amount. The data are transmitted to the card-issuing bank. The card-issuing bank accepts or denies the transaction. If the transaction is authorized, the customer signs to accept liability for the transaction. In the case of a debit card, the customer enters a personal identification number or sign the sales receipt to accept liability for the transaction. At the end of that day, the retailer submits the customer’s transactions along with all of the other credit card transactions to its depository institution (retailer’s bank), which credits the retailer usually in 1 to 2 business days. The credit card company is then responsible for creating the net settlement positions that result in the transfer of funds from the card-issuing bank to the retailer’s bank. These transfers typically occur by Fedwire funds tranfers through a correspondent bank. The card-issuing bank would then bill the customer. When the customer pays the bill, the cycle is complete, as shown in figure 2. Debit card transactions are authorized and cleared in a similar fashion to credit cards, except that they settle by debiting customers’ accounts and crediting retailers’ accounts on the next business day. Depository institutions use a variety of channels to settle credit and debit card transactions, including accounts at a common correspondent, ACH networks, and Fedwire. Final settlement of ACH transfers processed by the Federal Reserve occurs through debits and credits to the accounts of depository institutions on the books of the Federal Reserve. ACH transfers that are processed only by private-sector ACH operators are net settled through the Federal Reserve. Float is created because of the time it takes to clear and settle payments, which affects retailers, consumers, and depository institutions. Float is generally defined as the lag between the receipt of a check or other payment and the settlement of that payment. This lag differs according to the method of payment. There is no float for cash. Checks are subject to the longest float, primarily due to the need to physically transport checks. Federal law and regulations prohibit depository institutions from paying interest on demand deposits consisting primarily of commercial checking accounts. Many depository institutions, however, offer “sweep” accounts to business customers as a mechanism by which these customers obtain interest earnings on account balances above negotiated account minimums. During the business week, the depository institution transfers, or “sweeps,” commercial checking account balances above an agreed minimum into other accounts on which interest might be paid, such as MMDAs, or into interest-earning nondeposit financial instruments. Depository institutions typically invest these funds in short- term, low-risk assets, such as U.S. Treasury bills and notes, or money market mutual funds, among others. Depository institutions do not pay interest earnings on funds deposited on the weekend because they are unable to invest these funds until the next business day. Overall, U.S. settlement schedules are similar to settlement schedules in most G-10 countries. In some Asian countries, settlement services are available for a limited number of hours on Saturdays. Specifically, in Singapore and Hong Kong settlement occurs Saturday mornings, in addition to Monday through Friday services. Recently, South Korea ended its Saturday settlement hours because many commercial banks are closed on Saturdays. Appendix II further illustrates international payment systems’ operating hours. Weekend settlement of financial transactions would provide small benefits for retailers and consumers, and little, if any, benefit for the economy as a whole. Retail industry representatives identified weekend interest earnings as the main potential benefit for retailers. However, our analysis of grocery industry data indicated that the grocery industry currently forgoes small potential interest income on its weekend sales relative to the grocery industry’s annual sales or the national economy. If weekend settlement were adopted, retailers also could realize some secondary benefits such as reducing the amount of cash held in stores. However, other secondary benefits such as accelerated settlement represent benefit transfers primarily from consumers or banks to retailers, creating no economic stimulus to the economy. Although retail industry representatives identified weekend interest earnings as the main benefit for retailers, our analysis suggested that investing retailers’ balances in sweep accounts and other investment vehicles over the weekend would provide minimal additional earnings to retailers and have virtually no impact relative to the economy as a whole. According to grocery industry publications, the industry had sales of $494 billion in year 2000, as seen in figure 3. Therefore, because depository institutions are unable to invest retailers’ weekend cash deposits until Monday, we estimated, based on grocery industry data, that the grocery industry forgoes approximately $2.6 million each year in after-tax interest earnings, assuming a 2 percent interest rate, and $6.6 million a year, assuming an average 5 percent interest rate. The corresponding forgone after-tax interest earnings for check transactions are $2.8 million and $7 million annually, at 2 percent and 5 percent interest rates, respectively. Finally, for credit and debit cards, the forgone interest earnings are $2.5 million and $6.4 million, at 2 percent and 5 percent interest rates, respectively. Table 1 illustrates the estimates. Appendix III provides details of our estimates. Applying the same assumptions to the entire retail sector, which had sales of $3.4 trillion in the year 2000, we estimated that the annual forgone after-tax interest earnings for that sector would be $53.9 million at a 2 percent interest rate and $134 million at a 5 percent interest rate. However, these benefits might be reduced if depository institutions raised their fees, in a way that passed costs to retailers, to cover the increased costs associated with weekend operations. Weekend settlement could provide a number of secondary benefits to retailers and consumers. For example, retailers noted that weekend settlement would provide secondary benefits, such as reduced amounts of cash in stores, thereby reducing potential losses due to theft and lower insurance costs. The accelerated settlement of transactions would also benefit retailers by lowering accounts receivable balances, as noncash payments owed to retailers settle faster. Grocery officials stated that cash represents a large risk for store employees, and therefore, on a daily basis, grocers tend not to maintain large amounts of cash in stores. Excess sums generally are sent to depository institutions, usually via armored car services. Under the current system, depository institutions are not open to accept retailers’ deposits on Saturday and Sunday evenings; therefore, deposits are generally maintained in store vaults or in bonded safes at the armored car services’ facilities, which is a cost to retailers. Banking industry representatives stated that retailers currently must pay to insure large amounts of cash over the weekend. Finally, accelerated settlement of transactions could also benefit consumers if they are the recipients of check payments by making funds available sooner, assuming that the EFAA and the Federal Reserve Board’s implementing regulations were amended to include weekends in the definition of “business day.” The adoption of weekend settlement would transfer float income among retailers, consumers, and depository institutions rather than create new earnings. For example, retailers would earn interest income previously earned by check and debit card users, but no new interest income or wealth would be created. For credit cards, retailers potentially would obtain faster funds availability, but because card issuing depository institutions offer deferred payment to customers, retailers might earn additional interest income at the expense of depository institutions. For checks and debit cards, if retailers and consumers both had access to interest-bearing accounts or services provided by depository institutions, weekend settlement would move money more quickly out of customers’ accounts and into retail sector accounts. On the other hand, retail industry representatives also stated that a disadvantage of weekend settlement would be that checks they had written would clear faster, thereby reducing interest currently earned on those funds. Faster funds availability from weekend settlement also could present drawbacks for consumers. Consumer advocates stated that consumers might face increased overdrafts if they did not adjust to the accelerated debiting of their checks. Weekend settlement would negatively affect those people who depend on check float to avoid account overdrafts. For example, consumers might write a check on a Friday afternoon for an amount greater than their account balance, knowing that on the following Monday their paycheck would be credited to the account and cover the amount of the check. Further, concerning the economy as a whole, the interest payments that retailers would receive from weekend settlement reflect transfers within the economy rather than the creation of income. For example, additional income that retailers might earn from weekend settlement of checks written or debit card transactions received from customers would be offset by corresponding losses of interest by check writers, debit card users, and depository institutions. Consumers with interest-bearing checking accounts would lose the interest they would have earned on checks written on Friday evenings and Saturdays. If checks were drawn on noninterest-bearing accounts, then depository institutions would lose funds on which they were not paying interest. Corporate treasurers of retail businesses noted that although they potentially could accumulate interest earnings if weekend settlement were adopted and interest-earning accounts were available, depository institutions might pass along some or all of the costs of operating on weekends to retailers and consumers in the form of higher fees, thus lessening the gains to retailers. Depository institutions stated that to pay interest, they would need to have access to short-term investment markets on weekends. Our analysis showed that weekend settlement would be unlikely to provide any stimulus to economic growth. Its only impact would be to make funds available on weekends that would otherwise be available on Monday. Because payment system actors and processes are interdependent, weekend settlement would require payment service providers that clear and settle retail and wholesale payments to open on weekends, resulting in increased capital and operational costs. The greatest concern that payment service providers expressed to us was the cost of additional computer system and staffing resources needed to mitigate the increased risk of operational failures that weekend settlement would present. Although they could not provide exact cost figures for the additional resources they would need, payment service providers stated that costs would be significant and potentially prohibitive for small depository institutions. According to payment service providers, these operational costs would exceed any potential benefits that weekend settlement could create, and likely would reduce productivity in the payment system. Moreover, they stated that alternatives to weekend settlement with lower operational costs currently exist, and that efforts in other areas are under way to increase payment system efficiency. Because the payment system consists of interdependent processes and relationships among payment system actors, weekend settlement would require many payment service providers to open on weekends. For example, private and Federal Reserve cash and check processing centers and check transportation networks would have to be fully operational on weekends so that cash and check transactions could be cleared.However, banking industry representatives pointed out that not all depository institutions’ branches would need to open. National and regional clearing organizations also would need to open so that transactions among depository institutions could be cleared, netted, and settled. According to depository institution officials we spoke with, both Federal Reserve and private ACH networks would have to open on weekends to facilitate settlement of check and debit card transactions. Similarly, private electronic network providers told us that Fedwire would need to open on weekends to facilitate final settlement of credit card transactions. In addition, depository institutions also stated that once retailers’ transactions are settled and their accounts are credited for weekend deposits, they would need government securities and money markets to open on weekends to invest these deposits and pay interest on excess sweep account balances. Federal Reserve and investment market officials told us that Fedwire and clearing organizations for investment markets also would need to open to clear and settle these transactions. Payment service providers we met with generally viewed weekend downtime for computer systems as critical to the smooth provision of clearance and settlement services during the business week. Payment service providers stated that most computer systems are used to test, upgrade, and maintain computer-system activities on weekends when production activities are limited. These ongoing weekend activities reduce the potential for operational failures during the business week. Business continuity testing of computer systems remains a high priority for financial markets after the terrorist attacks of September 11, 2001. These tests generally take place on weekends and sometimes take more than 1 day to complete. Depository institution and clearing organization officials also said that weekend downtime is important for resolving problems that occur when implementing new software applications or upgrades to existing applications. Like other payment service providers, Federal Reserve officials told us that the Federal Reserve uses weekends to maintain and test its payment service applications and its internal accounting system that are used to settle payments. Most payment service providers told us that because tests, upgrades, and maintenance would have to continue if weekend settlement were adopted, they would need additional computer hardware and software to simultaneously perform weekend settlement and regular weekend activities, thereby increasing capital costs. One private electronic payment network that moved from a 5 day production schedule to a 7 day production schedule for transaction processing characterized its costs as substantial. The network had to purchase additional hardware to double computer system capacity so that it could maintain complete redundancy in production, contingency, and testing activities 7 days a week. Representatives for the network said that their case could be an example of the potential hardware resources that other payment service providers could face if weekend settlement were adopted. Officials at a large depository institution and investment market representatives pointed out that payment service providers would have to modify each line of relevant software code to reflect Saturdays and Sundays as valid settlement dates. The depository institution officials said that their retail banking operations would require code changes for the institution’s 80 software applications—with estimated costs in the millions of dollars. Clearing organizations also identified the need for additional software to carry out settlement on weekends and estimated that software costs would exceed potential hardware costs. Additional staff needed to carry out weekend settlement also would increase operational costs for payment service providers. Some payment service providers estimated that staffing costs for weekend settlement could increase current operating budgets by up to 40 percent. For instance, depository institutions would require additional staff in departments that currently are not open on weekends, such as staff to handle check presentments and return checks and staff to manage their general ledgers and Federal Reserve accounts. Banking industry representatives noted that small depository institutions that perform their own clearing and processing activities would need to hire additional staff to prepare cash and checks for weekend shipment to local Federal Reserve Banks and branches. This could be particularly costly for small depository institutions because “back-office” staffs often consist of one person. Similarly, Federal Reserve officials said that additional staff would be needed for check processing, ACH, Fedwire, internal accounting, credit and risk management, and information technology operations, as well as other support functions. Investment market representatives commented that the human capital costs of weekend operations would be high because firms likely would have to pay senior staff at premium rates to work on weekends. Investment market representatives said that operating on weekends would decrease market efficiency and that they generally expected that weekend markets would be inefficient and illiquid because weekend trading activity likely would be low. Investment market representatives pointed out that liquidity in weekend markets would be generated only if there were sufficient numbers of investment firms interested in obtaining retailers’ excess sweep account balances. They noted that investment firms have many other options for short-term investment beyond government securities and money market instruments—typical investment vehicles used by depository institutions for sweep account funds. For these reasons, they noted that they sometimes recommend closing markets early before holidays, such as Good Friday, if trading volumes are low, to preserve market efficiency and create greater liquidity. In general, they did not expect weekend investment market liquidity to offset the potential operating costs. Similarly, depository institution officials and clearing organizations anticipated that weekend settlement would result in the spreading out current 5-day transaction volume over 7 days of operations, thereby decreasing system efficiency. Two proposed variations of 7 day settlement are currently viewed as not practical and too costly. The first variation involves a 6 day settlement schedule, where settlement would occur Monday through Saturday. Payment service providers told us that a 6 day settlement schedule would present lower operational risk and costs relative to a 7 day settlement schedule, but currently would be complicated and too expensive. Some payment providers noted that once technology more generally allows faster computer processing, 6-day settlement could be possible because it would provide 1 day during which computer system maintenance could be performed. The second variation relates to selective processing of transactions by payment method—for example, weekend processing of cash or check transactions. However, according to banking industry representatives, processing and settlement by payment method would be impractical because depository institutions’ demand deposit accounting systems, which debit and credit customer accounts, do not differentiate transactions by payment methods. Rather, representatives from depository institutions stated that large batches of transactions are queued for debiting from and crediting to customer accounts regardless of the payment method associated with the transaction. Federal Reserve officials also said that selective settlement also would require the supporting settlement infrastructure to open on weekends, such as Fedwire funds transfer and securities transfer services. Therefore, such an approach would not lower operational costs of settling transactions on weekends. We identified current banking services that provide business customers with some of the advantages of weekend settlement but do not require payment service providers to incur costs of weekend operations. For example, officials at a large depository institution said that one of its large business customers requested a service whereby, on Mondays, the depository institution provides backdated interest on funds that the customer deposits on Mondays, as if the funds had been deposited and credited to the customer’s account over the weekend. Officials from the depository institution noted that this service is no different than other services in that it is provided to the customer for a fee. Banking industry representatives told us that some depository institutions offer “fully analyzed” accounts, whereby they calculate the average daily account balances of commercial customers and determine daily interest earnings credit based on those figures. They noted that fully analyzed accounts allow account fees and charges to be offset by earnings credit based on the average daily collected account balance. Depository institution officials and banking industry representatives said that these services are offered within the context of existing relationships with commercial customers. They generally viewed these services as alternative methods of providing weekend interest earnings for business customers that do not require other payment service providers to be in operation on weekends. According to Federal Reserve and clearing organization officials, ongoing efforts to increase payment system efficiency relate to extending Fedwire’s hours of operation during the business week to correspond with activity in Asian markets. Although extending Fedwire’s hours of operation would not provide retailers with weekend interest earnings, it could increase efficiency in the payment system by allowing firms to consolidate risk management resources. Payment service providers generally expected that in the short term, increased efficiency in the payment system would come from converting traditionally paper-based payment methods into electronic form. Some payment service providers said that check truncation—the conversion of a paper check into an electronic equivalent that is transmitted in place of the original check— would eliminate the float that transporting checks creates in the check collection process. Officials at one clearing organization said that weekend settlement costs could be lowered if there were an increase in electronic payment instruments and a corresponding decline in paper- based payment instruments within the payment system. Our legal research found no federal law that would specifically prohibit banks, clearing organizations, or other entities from engaging in weekend settlement operations. Some states, however, have laws prohibiting banks from doing business on Sundays or state holidays. OCC has determined that state bank closure laws do not apply to national banks. National banks, therefore, would not be prohibited from engaging in weekend settlement operations. However, in states prohibiting banks from operating on certain days, state-chartered banks would be precluded from conducting such operations on those days unless the closure laws were preempted. The federal financial institution regulators do not specifically regulate the hours of operation of state-chartered institutions, so state closure laws generally have not been preempted with respect to such institutions. We express no opinion regarding the extent to which the Federal Reserve, pursuant to its authority over the payment system, could preempt state closure laws in order to provide for weekend settlement services. It appears that Congress could choose to preempt such laws through legislation. Because they have not been preempted, state closure laws applicable to state banks could interfere with the development of a uniform national weekend settlements system. Our research indicates, however, that a relatively small number of states have Sunday closure laws. In addition to state closure laws, development of a weekend settlement system involves other legal considerations. For example, under the EFAA and the Federal Reserve’s Regulation CC, deposited funds must be made available and checks must be returned within time periods based on “business days” and “banking days.” The term “business day” is defined as a calendar day other than a legal holiday, Saturday, or Sunday; a “banking day” is a business day on which a bank office conducts substantially all of its banking operations. Even if banks were to conduct settlement operations over the weekend, such operations would not necessarily result in corresponding funds availability and check returns because weekends are not counted as business days. Moreover, the settlement process could be complicated by a lack of uniformity and predictability in bank operations that might exist if banks were to conduct their clearing and settlement operations using different timetables. Other legal considerations include the impact of wage and hour laws and matters of safety and soundness. To the extent bank employees involved in settlement operations are subject to federal and state wage and hour laws, institutions would have to ensure that weekend operations did not run afoul of provisions requiring, among other things, the payment of overtime for work in excess of 40 hours per week. Concerning safety and soundness issues, banks would have to ensure that utilizing computer systems and other resources on weekends would not compromise their ability to maintain and update financial and security systems. We received technical comments and corrections on a draft of this report from Treasury and the Federal Reserve that we incorporated, as appropriate. In addition, the Federal Reserve provided written comments in which it agreed that the potential costs of weekend settlement would outweigh the associated benefits. These comments are reprinted in appendix IV. As agreed with your office, we plan no further distribution of this report until 30 days from its issue date unless you publicly release its contents sooner. We will then send copies of this report to the Chairman of the Committee on Financial Services, House of Representatives; the Ranking Minority Member of the Committee on Financial Services, House of Representatives; the Ranking Minority Member of the Subcommittee on Financial Institutions and Consumer Credit, House of Representatives; the Secretary of the Department of the Treasury; and the Chairman of the Board of Governors of the Federal Reserve System. We will make copies available to others on request. In addition, this report is also available on GAO’s Web site at no charge at http://www.gao.gov. Please contact me or Barbara Keller, Assistant Director, at (202) 512-8678 if you or your staff have any questions concerning this letter. To determine the potential benefits of weekend settlement, we interviewed and requested data from consumers groups, retail representatives, and payment service providers. We focused our study on the clearance and settlement of retail payments made by cash (which requires no clearing and settles instantaneously), checks, debit, and credit cards. We spoke with consumer advocacy groups to obtain the consumer perspective, and we interviewed representatives from industries within the retail sector, including grocery industry and home improvement industry representatives. We focused on the grocery industry because the majority of sales take place on weekends and primarily involve cash, check, and debit card transactions. To estimate the forgone interest earnings of the grocery industry, we obtained studies from third-party sources, some of which were conducted by industry participants. We have not assessed the quality of the research methodologies used in these studies. We used calendar year 2000 grocery industry sales data from the Progressive Grocer (PG), an industry publication. This was the latest year for which complete information was available. We also obtained grocery industry sales data from the U.S. Census Bureau for comparison purposes. We used the results of a payments study, performed by a large electronic network provider, that tracked the purchasing behavior of 20,000 consumers to determine what percentage of grocery sales are made with cash, check, and debit cards, respectively. We also used the results of a consumer survey on when consumers shop during the week, published in the Progressive Grocer 2001 Annual Report and short-term interest rate data from the Board of Governors of the Federal Reserve System. Appendix III provides details on our calculation of the forgone interest earnings. We spoke with payment system providers to gain their perspectives on the potential costs and operational issues involving weekend settlement. We interviewed officials from several depository institutions, banking and bond market industry representatives, clearing organizations, and private electronic payment network operators. We interviewed officials from various components of the Federal Reserve involved in the provision of payment system services including cash and check processing, check transportation, ACH services, wholesale payments services, and open market operations. We also spoke with senior staff from the Department of the Treasury about the potential implications of weekend settlement on the Treasury securities market. We obtained information from corporate treasury representatives on the perceived advantages and disadvantages of weekend settlement. Finally, to analyze and compare U.S. settlement schedules, we obtained information from representatives of central banks in selected foreign countries on the operating schedules of their respective settlement systems. We also obtained information from central banks’ Web sites. We focused our analysis of international settlement schedules on countries with relatively modern, industrialized economies in selected geographic areas—specifically, Asia, Europe, North America, Australia, and New Zealand, as depicted in appendix II. We based our analysis of potential legal considerations involving weekend settlement on research of relevant federal and state statutes, regulations, judicial decisions, and other legal databases, and conducted interviews with banking agency attorneys and representatives of payment system providers. We conducted our work in Washington, D.C., Atlanta, Georgia, and New York, New York, between February and September 2002 in accordance with generally accepted government auditing standards. Wholesale System Fedwire CHIPS Bank of Japan – Network (BOJ – NET) Large Value Transfer System (LVTS) Trans-European Automated Real-time Gross settlement Express Transfer (TARGET) Society for Worldwide Interbank Financial Telecommunications – Payment Delivery System (SWIFT – PDS) Exchange Settlement Account System (ESAS) Mon – Fri Sat Mon – Fri Sat Mon – Fri 9:00 am –7:00 pm (GMT +12) 8:00 pm –8:40 am (+1 day) Closed 12:01 am Sat – 11:59 pm Sun 9:00 am – 5:30 pm (GMT +8) 9:00 am – 12:00 pm 9:00 am – 6:30 pm (GMT +8) 9:00 am – 2:45 pm 9:30 am – 4:30 pm (GMT +9) All countries have real-time gross settlement systems except Canada, which has a net-settlement system. The following European Union countries participate in TARGET: Austria, Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg, The Netherlands, Portugal, and Spain. Grocery industry representatives said that because the settlement system is not open on weekends, retailers are losing money because the funds they receive on Friday evening, Saturday, and Sunday cannot be credited to their accounts and earn interest before Monday, at the earliest. These calculations estimate the amount of interest forgone to the grocery industry for retail transactions made by cash, checks, and credit and debit cards. This calculation measures the upper bound of forgone earnings. It assumes that every store would deposit every dollar and every check at the bank on the day that it is received. It also does not take into account that payments made by retailers, under weekend settlement, would be debited from their accounts earlier, thereby potentially decreasing their interest earnings. To measure forgone interest earnings, we used the federal funds rate, the rate at which a bank with excess reserves at a Federal Reserve district bank charges other banks that need overnight funds. This is an appropriate measure because the excess grocery funds would be invested in a similar, short-term fashion. The average federal funds rate from January 1, 1998, to January 1, 2002, was approximately 5 percent. The current federal funds rate is approximately 2 percent. We estimated forgone earnings at both of these rates. To gain credit for deposits for a given day, retailers must have deposits collected by approximately 2:00 p.m. on that day. Grocery industry representatives stated that most Friday sales tend to occur after that hour; therefore, we assumed that all proceeds from Friday, Saturday, and Sunday do not get deposited until Monday. However, Sunday proceeds deposited on Monday generally would be processed as quickly as money deposited Monday through Thursday; therefore, we did not include Sunday proceeds as idle balances. In addition to those named above, Tonita W. Gillich, Marc Molino, Robert Pollard, Carl Ramirez, Barbara Roesmann, Nicholas Satriano, Paul Thompson, and John Treanor made key contributions to this report.

Summary: The U.S. payment system is a large and complex system of people, institutions, rules, and technologies that transfer monetary value and related information. The nation's payment system transfers an estimated $3 trillion dollars each day--nearly one third of the U.S. gross domestic product. Currently, settlement--the final step in the transfer of ownership involving the physical exchange of payment or securities--occurs only during the business week. Some retailers, however, generate approximately half their weekly sales on weekends--when depository and other financial institutions generally are closed--receiving cash, checks, and electronic payments that are not credited to their accounts until at least the next business day. Weekend settlement of financial transactions would provide small benefits to retailers and consumers, and little, if any, benefit to the economy as a whole. Because payment system actors and processes are interdependent, implementing weekend settlement would require payment service providers that clear and settle retail and wholesale payments to open on weekends, resulting in significantly increased operational costs. Although there are no direct federal prohibitions against weekend settlement, state laws that are not preempted by federal laws or regulations providing for weekend settlement could interfere with development of a uniform, national 7 day settlement system.
