Some economists and pundits have been arguing for banning Money in physical form such as banknotes and coins. More. Used in this sense, cash is the 11% of the From the Latin word moneta, nickname that was given by Romans to the goddess Juno because there was a minting workshop next to her temple. Money is any item that is generally accepted as payment for goods and services and repayment of debts, such as taxes, in a particular region, country or socio-economic context. Its onset dates back to the origins of humanity and its physical representation has taken on very varied forms until the appearance of metal coins. The banknote, a typical representati... More stock (calculated as M2) made of This is often used as a generic expression to refer to banknotes, versus the “metal currency” expression, which refers to coins. More in the United States. The rest of the U.S. money stock consists almost entirely of electronic entries for bank deposits and money market funds. (Coins, which are not included in the definition of cash here, add only 3% to The money used in a particular country at a particular time, like dollar, yen, euro, etc., consisting of banknotes and coins, that does not require endorsement as a medium of exchange. More.) Through checks, debit cards, direct transfers, etc., electronic money makes up nearly 60% of transactions and more than 80% of their value. Cash is even less used in some Scandinavian countries, which many see as becoming cashless societies.
The best-known proponent of banning cash is Harvard University professor Kenneth S. Rogoff1. Banning cash means that the government would stop issuing it and would buy the outstanding stock in The Eurosystem comprises the European Central Bank and the national central banks of those countries that have adopted the euro. More for interest-bearing securities. Rogoff proposes a gradual phasing out over 10 to 15 years, starting with $100 and $50 bills and then extending to $20 bills. Eventually, only denominations of $10 and under—which now represent only 3% of the cash—would be allowed, or perhaps replaced by heavy coins.
This is a much bigger issue than it first appears to be. Not only would banning cash as we know it inconvenience a lot of people, but also, as we shall see, it would come with many new regulations and controls. For example, it would require tight regulation of crypto-currencies, harassment of “cash hoarders,” and prohibition of prepaid cards (which are too similar to cash).
The arguments that Rogoff and others invoke for a partial or total prohibition on cash are its widespread use in criminal activities, its constraining effect on monetary policy, and its diminishing convenience for legitimate use. Each of these arguments is flawed, as I will explain later. Let’s look more closely at the first two arguments.
The main argument is that cash facilitates crime. It is anonymous and leaves no See Banknote paper. More trail. Larger bills are relatively easy to carry and to store, and constitute a large proportion of currency—80% for $100 bills. Surveys suggest that American consumers hold only a small proportion of the cash in domestic circulation, and, thus, most of the large bills are supposedly used in criminal activity: drug-related transactions, cash sales and salaries in the underground economy (to pay illegal immigrants, for example), and terrorism. The situation is similar with national currencies in other countries.
The second main argument for banning cash requires a detour into macroeconomic theory. When government wants to stimulate aggregate demand to escape a recession or slow growth (as is happening currently), it will, according to mainstream theory, push down interest rates. When interest rates are close to zero (as they currently are), reducing them further requires pushing them down into negative territory. No one had experimented with this idea until the past few years in a few countries (including some countries in the Eurozone). But if saved money (say, in a bank account) brings a negative return or, in other words, requires a fee, individuals and businesses will, at some point, start The term refers to the use of cash as a store of value. However, the term has a negative connotation of concealment, and is often used in the context of the war on cash. See Precautionary Holdings. More cash instead. This would nullify the policy goal of making them spend the money. Thus, monetary policy cannot go much below the “zero bound” of interest rates. The advantage of a cashless society, the argument goes, would be to have no zero bound, thus liberating the full power of monetary policy.
There is a possible universe in which these arguments against cash would be true. In such a world, politicians and bureaucrats would know and single-mindedly pursue the public interest (that is, what is in the interest of everybody), economists and bureaucrats would perfectly understand the consequences of government policies, clear laws and transparent regulations would never be used for anything else than their well-understood original purposes, and prosecutors would always protect individual rights.
But the world in which we live is very different. As Lord Acton said, “Power tends to corrupt and absolute power corrupts absolutely.” It is in the interest of nearly everybody that government power be constrained. In Western societies, social and political institutions have developed for this purpose.
Consider the crime argument. Constraining government, even in fighting crime, forms the constitutional basis of a free society. Criminals are probably more likely than blameless citizens to invoke the Fifth Amendment against self-incrimination, or the Fourth Amendment against “unreasonable searches and seizures.” The Eighth Amendment, against “cruel and unusual punishments,” looks even more tailor-made for criminals. But this is not a valid reason to abolish these constitutional rights, which are meant to protect individuals against government overreach.
A similar argument is relevant to neutral things like cash. Why should innocent individuals be prevented from using cash only because criminals use it improperly? It is estimated that alcohol is involved in a third of crimes2, but this is not a good argument for a new Prohibition. Preventing crime should normally be done by dissuasive punishments, not by prior controls on non-criminal behavior.
Moreover, not all crimes are real crimes3. Terrorism is a real crime, but there are already many laws and regulations against actions committed by terrorists. And cash is probably not a major factor in terrorism. Victimless crimes are different. Tax evasion, selling and buying drugs or cigarettes among adults, and ordinary activities in the underground economy are “criminal” in a different sense than murder.
Furthermore, some activities that the law currently defines as crimes (in certain countries) may actually provide useful built-in constraints against abuse of power. Tax dodging, for example, limits the voracity of Leviathan and its tax exploitation. It increases the cost to the state of raising taxes and, thus, tends to maintain them at a level more likely to gain the consent of most citizens4.
The same argument applies to the underground economy more generally. It provides a built-in constraint against overregulation. As regulation increases, more people—consumers, entrepreneurs, unfashionable minorities—move to the underground economy. Thus, government cannot regulate past a certain point, and this constraint kicks in more rapidly in a free society.
That cash plays a role in making these built-in constraints more effective against abuses of power is a benefit, not a cost. In a free society, one could provide a cogent argument for increasing the The figure or amount written on the banknote or coin which indicates the amount of its economic value. It is usually written in letters and numbers. More of the largest-denomination notes. The largest Swiss note, for example, is 1,000 Swiss francs (roughly the same as $1,000 at the September 22, 2016 The rate at which one currency will be exchanged for another. More).
Because of all these constraints, the cost of fighting crime is certainly higher in a free society. But for the vast majority of individuals, the benefits of freedom are even higher. Liberty is not a bug—it’s a feature.
Facilitating negative interest rates is the second argument used against cash, and its cogency is far from obvious. Monetary theory is complex. Is it true that a recession requires government to try to boost “aggregate demand”? Does it work? Different schools of economic thought give different answers. We still debate the causes of the Great Depression 80 years later, not to mention the controversies about the recent Great Recession. The precise influence of central banks on interest rates is debatable5. We don’t understand why exactly interest rates have been on a downward trend since the 1980s. Economists know relatively little about the efficacy of monetary policy. Politicians and the general public know even less.
The consequences of a deliberate policy of negative interest rates are very uncertain. Negative rates don’t seem to work at low doses, as we see in Europe and Japan. Many observers are worried that the current low interest rates are already fueling an asset bubble—perhaps in commercial real estate6. The hubris of proposing a new prohibition in order to facilitate a more daring experiment with negative interest rates is puzzling.
The diminishing convenience argument cannot bolster the case against cash. To argue against the usefulness of cash is to deny the revealed preferences of many individuals. The fact that cash has not disappeared even in non-criminal hands means that it is convenient for many individuals. Economic efficiency is defined in terms of what individuals want.
Why many individuals want cash, including large bills, is, like all preferences, ultimately subjective. Some may value privacy more than others. Depending on risk aversion, cash also provides a sort of insurance policy. Holding cash or at least having access to it reserves the capability, if ever needed, to avoid capital controls or outright confiscation, by moving money across borders. Cash can also protect individuals and their intermediaries—pension funds, life insurance companies, etc.—against negative interest rates on their savings. It is for each individual to make his own cost-benefit analysis.
Foreigners hold at least one half of U.S. cash—in Zimbabwe and some South American countries, for example, to protect themselves, often illegally, against the debasement of their own currencies by their own governments. This reminds us that good cash is often useful. It also suggests that, as the economist would normally assume, the welfare of these foreigners should be included when evaluating policy proposals.
The real issue is whether governments, including the U.S. government, should be the ones supplying cash. It is true that producing cash to satisfy transaction demand costs nothing to the taxpayer: on the contrary, the central bank earns seigniorage (the difference between the cost of printing banknotes and their market value). It is an intriguing fact that the availability of government currency provides protection against government intrusion itself.
Were the U.S. government to stop producing Monetary unit of the United States of America, and a number of other countries e.g. Australia, Canada and New Zealand. More bills, Americans would probably experience little inconvenience, as foreign cash (pounds, Swiss francs, euros…), notes from private banks, or cryto-currencies could easily be substituted.7 But proponents of cash prohibition also want to ban these substitutes. What they don’t like is any monetary instrument that reduces government control.
Mission creep naturally follows from the logic of government regulation. For example, the war on drugs generated the new crime of The operation of attempting to disguise a set of fraudulently or criminally obtained funds as legal, in operations undeclared to tax authorities, and therefore not subjected to taxation. Money laundering activities are strongly pursued by authorities and in most countries, there are strict rules for credit institutions to cooperate in the fight against money laundering operations, to declare and report any transactions that could be considered suspicious. More, boosted civil forfeiture laws8, and contributed to mass criminalization. Money laundering regulations have scared American banks into retreating from many foreign activities—so that now, the U.S. government feels obliged to assure them that it does not, in this case and for the time being, take a zero-tolerance approach!9
Enforcing a total or partial ban on cash would generate a new crop of regulations and controls, as Kenneth Rogoff admits. During the implementation period, restrictions on the maximum size of cash payments could be required. As cash is being phased out, other measures would have to be taken, including subsidized debit cards or their provision by government for low-income people. The use of foreign cash or any other cash would have to be prevented. Crypto-currencies would have to be regulated. Fees on withdrawals and deposits of any remaining cash might be required. Moreover, in case of very negative interest rates, prepayment of taxes would have to be controlled, and banks might need bailouts. Many savers would no doubt ask for state help. Other regulations would be adopted to close newly discovered loopholes.
Government is not manned by angels, and constraining its actions is as necessary as it ever was, if not more so. Banning cash would do the opposite, which is the broad reason why it is a bad idea. In their ivory towers, policy makers and their economic advisers sometimes forget that efficiency is what individuals want. Indeed, it is often in the policy makers’ own interest to forget it. Contrary to the prohibitionist temptation, the default option should not be to intervene, but to leave people free to strike their own bargains in free markets.
