	The Once, But Perhaps Not Future, King

Because of technological advances in digitization and data processing, electronic forms of payment have become increasingly available, convenient, and cost efficient. Established technologies, such as credit and debit cards, have long been a popular payment option. Although cash remains an important method of payment in the United States (see Figure 1 ), anecdotal reporting suggests that various electronic payment systems have become so effective and inexpensive relative to cash payments that some U.S. businesses—even those at which sales generally have a low dollar value—are increasingly choosing not to accept cash. Some observers have examined the consequences of an evolution away from cash. Proponents of reducing the use of physical currency (or even eliminating it all together and becoming a cashless society ) argue that it will generate important benefits, including potentially improved efficiency of the payment system, a reduction of crime, and less constrained monetary policy. Proponents of maintaining cash as a payment option argue that significant reductions in cash usage and acceptance would further marginalize people with limited access to the financial system, increase the financial system's vulnerability to cyberattack, and reduce personal privacy. The noncash payment systems include traditional electronic payment systems (such as credit cards or payment apps) and alternative electronic payment systems, focusing on private systems using distributed ledger technology (such as cryptocurrencies) and central bank digital currencies (which are only under consideration by central banks at this time). Advantages and Costs of Cash

				Cash Advantages for Consumers and Businesses

One of the main benefits of cash is that it is a simple, easy, robust payment mechanism that requires no ancillary technologies. Cash also acts as a safe asset in which to invest savings and its usage can involve a high degree of privacy, features that will be examined in more detail in the " Potential Costs and Risks of a Reduced Role for Cash " section below. Cash Costs for Consumers and Businesses

Using and accepting cash involves certain costs to consumers and businesses. Other costs—including consumer losses through theft, misplacement, or accidental destruction of cash—are more difficult to estimate. Cash Effects on Government Revenues

In addition to its impacts on consumers and businesses, cash directly affects government revenues through three main mechanisms: (1) seigniorage (i.e., the "profit" the government makes by producing cash), (2) Federal Reserve remittances to the Treasury, and (3) tax evasion. Advantages and Costs of Traditional Noncash Payment Systems

				Traditional Noncash Payment System's Advantages

Payment based on physically exchanging currency has some notable shortcomings that can be addressed by a payment system based on maintaining account ledgers. These intermediaries store and protect huge amounts of data. In addition, the systems themselves could be susceptible to disruption from cyberattacks. The use of these systems to make payments is quite rare relative to cash and traditional systems, and the role they will play in the future is speculative. With respect to alternative electronic payment systems, the section examines their potential advantages, costs, and obstacles to their widespread adoption. To meet costs and earn profits, these institutions charge various user fees. Several characteristics of cryptocurrency undermine its ability to serve the functions of money in a payment system. Central Bank Digital Currencies

				Overview

The risks and challenges posed by private digital currencies have led some observers to suggest that perhaps central banks should offer their own central bank digital currencies (CBDCs) to realize certain hoped-for efficiencies in the payment system in a way that would be "safe, robust, and convenient." Various trends suggest that due to market preference or government policy, the role of cash in the payment system has begun to decline and may continue to decline, perhaps significantly, in coming years. If the relative benefits and costs of cash and the various other payment methods evolve in such a way that cash is significantly displaced as a commonly accepted form of payment, that evolution could have a number of effects, both positive and negative, on the economy and society. Privacy Concerns

Opening a bank account or otherwise using traditional noncash payment systems generally requires an individual to divulge certain basic personal information, such as name, Social Security number, and birthdate, to a financial institution. Now or in the near future, policymakers may face decisions about whether to impede or hasten the decline of cash and consider the implications of doing so. Reportedly, many Swedes are generally in favor of the trend (the displacement of cash is due largely to consumer preference), though some have voiced concerns about financial access issues that the change causes for certain groups, such as the elderly.
Electronic forms of payment have become increasingly available, convenient, and cost efficient due to technological advances in digitization and data processing. Anecdotal reporting and certain analyses suggest that businesses and consumers are increasingly eschewing cash payments in favor of electronic payment methods. Such trends have led analysts and policymakers to examine the possibility that the use and acceptance of cash will significantly decline in coming years and to consider the effects of such an evolution.
Cash is still a common and widely accepted payment system in the United States. Cash's advantages include its simplicity and robustness as a payment system that requires no ancillary technologies. In addition, it provides privacy in transactions and protection from cyber threats or financial institution failures. However, using cash involves costs to businesses and consumers who pay fees to obtain, manage, and protect cash and exposes its users to loss through misplacement, theft, or accidental destruction of physical currency. Cash also concurrently generates government revenues through "profits" earned by producing it and by acting as interest-free liabilities to the Federal Reserve (in contrast to reserve balances on which the Federal Reserve pays interest), while reducing government revenues by facilitating some tax avoidance.
The relative advantages and costs of various payment methods will largely determine whether and to what degree electronic payment systems will displace cash. Traditional noncash payment systems (such as credit and debit cards and interbank clearing systems) involving intermediaries such as banks and central banks address some of the shortcomings of cash payments. These systems can execute payments over physical distance, allow businesses and consumers to avoid some of the costs and risks of using cash, and are run by generally trusted and closely regulated intermediaries. However, the maintenance and operation of legacy noncash systems involve their own costs, and the intermediaries charge fees to recoup those costs and earn profits. The time it takes to finalize certain transactions—including crediting customer accounts for check or electronic deposits—can lead to consumers incurring additional costs. In addition, these systems involve cybersecurity risks and generally require customers to divulge their private personal information to gain system access, which raises privacy concerns.
To date, the migration away from cash has largely been in favor of traditional noncash payment systems; however, some observers predict new alternative systems will play a larger role in the future. Such alternative systems aim to address some of the inefficiencies and risks of traditional noncash systems, but face obstacles to achieving that aim and involve costs of their own. Private systems using distributed ledger technology, such as cryptocurrencies, may not serve the main functions of money well and face challenges to widespread acceptance and technological scalability. These systems also raise concerns among certain observers related to whether these systems could facilitate crime, provide inadequate protections to consumers, and may adversely affect governments' ability to implement or transmit monetary policy. The potential for increased payment efficiency from these systems is promising enough that certain central banks have investigated the possibility of issuing government-backed, electronic-only currencies—called central bank digital currencies (CBDCs)—in such a way that the benefits of certain alternative payment systems could be realized with appropriately mitigated risk. How CBDCs would be created and function are still matters of speculation at this time, and the possibility of their introduction raises questions about the appropriate role of a central bank in the financial system and the economy.
If the relative benefits and costs of cash and the various other payment methods evolve in such a way that cash is significantly displaced as a commonly accepted form of payment, that evolution could have a number of effects, both positive and negative, on the economy and society. Proponents of reducing cash usage (or even eliminating it all together and becoming a cashless society) argue that doing so will generate important benefits, including potentially improved efficiency of the payment system, a reduction of crime, and less constrained monetary policy. Proponents of maintaining cash as a payment option argue that significant reductions in cash usage and acceptance would further marginalize people with limited access to the financial system, increase the financial system's vulnerability to cyberattack, and reduce personal privacy. Based on their assessment of the magnitude of these benefits and costs and the likelihood that market forces will displace cash as a payment system, policymakers may choose to encourage or discourage this trend.
