Hyperinflation

A vicious circle is created in which more and more inflation is created with each iteration of the ever increasing money printing cycle. This is not the same as and has nothing to do with, for example, the US Federal Reserve Bank´s and the Bank of Japan´s "Quantitative easing (QE)" programs.

Hyperinflation becomes visible when there is an unchecked increase in the money supply (see hyperinflation in Zimbabwe) usually accompanied by a widespread unwillingness on the part of the local population to hold the hyperinflationary money for more than the time needed to trade it for something non-monetary to avoid further loss of real value. Hyperinflation is often associated with wars (or their aftermath), currency meltdowns like in Zimbabwe, and political or social upheavals.

In 1956, Phillip Cagan wrote The Monetary Dynamics of Hyperinflation, generally regarded as the first serious study of hyperinflation and its effects. In it, he defined hyperinflation as a monthly inflation rate of at least 50%. International Accounting Standard 1 requires a presentation currency. IAS 21 provides for translations of foreign currencies into the presentation currency. IAS 29 establishes special accounting rules for use in hyperinflationary environments, and lists four factors which can trigger application of these rules:

The IASB is currently requesting comment on its Exposure Draft: Severe Hyperinflation - Proposed Amendment to IFRS 1 - in which it proposes that the currency of a hyperinflationary economy is subject to severe hyperinflation if it has both of the following characteristics: (a) a reliable general price index is not available to all entities with transactions and balances in the currency. (b) exchangeability between the currency and a relatively stable foreign currency does not exist.

The main cause of hyperinflation is a massive and rapid increase in the amount of money that is not supported by a corresponding growth in the output of goods and services. This results in an imbalance between the supply and demand for the money (including currency and bank deposits), accompanied by a complete loss of confidence in the money, similar to a bank run. Enactment of legal tender laws and price controls to prevent discounting the value of paper money relative to gold, silver, hard currency, or commodities, fail to force acceptance of a paper money which lacks intrinsic value. If the entity responsible for printing a currency promotes excessive money printing, with other factors contributing a reinforcing effect, hyperinflation usually continues. Often the body responsible for printing the currency cannot physically print paper currency faster than the rate at which it is devaluing, thus neutralizing their attempts to stimulate the economy.

Hyperinflation is generally associated with paper money, which can easily be used to increase the money supply: add more zeros to the plates and print, or even stamp old notes with new numbers. Historically, there have been numerous episodes of hyperinflation in various countries followed by a return to "hard money". Older economies would revert to hard currency and barter when the circulating medium became excessively devalued, generally following a "run" on the store of value.

Hyperinflation effectively wipes out the purchasing power of private and public savings, distorts the economy in favor of extreme consumption and hoarding of real assets, causes the monetary base, whether specie or hard currency, to flee the country, and makes the afflicted area anathema to investment. Hyperinflation is met with drastic remedies, such as imposing the shock therapy of slashing government expenditures or altering the currency basis. An example of the latter occurred in Bosnia and Herzegovina in 2005, when the central bank was allowed to print only as much money as it had in foreign currency reserves. Another example was the dollarization in Ecuador, initiated in September 2000 in response to a massive 75% loss of value of the Sucre currency in early January 2000. Dollarization is the use of a foreign currency (not necessarily the U.S. dollar) as a national unit of currency.

The aftermath of hyperinflation is equally complex. As hyperinflation has always been a traumatic experience for the area which suffers it, the next policy regime almost always enacts policies to prevent its recurrence. Often this means making the central bank very aggressive about maintaining price stability, as was the case with the German Bundesbank or moving to some hard basis of currency such as a currency board. Many governments have enacted extremely stiff wage and price controls in the wake of hyperinflation but this does not prevent further inflating of the money supply by its central bank, and always leads to widespread shortages of consumer goods if the controls are rigidly enforced.

As it allows a government to devalue their spending and displace (or avoid) a tax increase, governments have sometimes resorted to excessively loose monetary policy to meet their expenses. Inflation is effectively a regressive consumption tax, but less overt than levied taxes and therefore harder to understand by ordinary citizens. Inflation can obscure quantitative assessments of the true cost of living, as published price indices only look at data in retrospect, so may increase only months or years later. Monetary inflation can become hyperinflation if monetary authorities fail to fund increasing government expenses from taxes, government debt, cost cutting, or by other means, because either

Theories of hyperinflation generally look for a relationship between seigniorage and the inflation tax. In both Cagan's model and the neo-classical models, a tipping point occurs when the increase in money supply or the drop in the monetary base makes it impossible for a government to improve its financial position. Thus when fiat money is printed, government obligations that are not denominated in money increase in cost by more than the value of the money created.

From this, it might be wondered why any rational government would engage in actions that cause or continue hyperinflation. One reason for such actions is that often the alternative to hyperinflation is either depression or military defeat. The root cause is a matter of more dispute. In both classical economics and monetarism, it is always the result of the monetary authority irresponsibly borrowing money to pay all its expenses. These models focus on the unrestrained seigniorage of the monetary authority, and the gains from the inflation tax. In Neoliberalism, hyperinflation is considered to be the result of a crisis of confidence. The monetary base of the country flees, producing widespread fear that individuals will not be able to convert local currency to some more transportable form, such as gold or an internationally recognized hard currency. This is a quantity theory of hyperinflation.

In neo-classical economic theory, hyperinflation is rooted in a deterioration of the monetary base, that is the confidence that there is a store of value which the currency will be able to command later. In this model, the perceived risk of holding currency rises dramatically, and sellers demand increasingly high premiums to accept the currency. This in turn leads to a greater fear that the currency will collapse, causing even higher premiums. One example of this is during periods of warfare, civil war, or intense internal conflict of other kinds: governments need to do whatever is necessary to continue fighting, since the alternative is defeat. Expenses cannot be cut significantly since the main outlay is armaments. Further, a civil war may make it difficult to raise taxes or to collect existing taxes. While in peacetime the deficit is financed by selling bonds, during a war it is typically difficult and expensive to borrow, especially if the war is going poorly for the government in question. The banking authorities, whether central or not, "monetize" the deficit, printing money to pay for the government's efforts to survive. The hyperinflation under the Chinese Nationalists from 1939-1945 is a classic example of a government printing money to pay civil war costs. By the end, currency was flown in over the Himalayas, and then old currency was flown out to be destroyed.

Hyperinflation is regarded as a complex phenomenon and one explanation may not be applicable to all cases. However, in both of these models, whether loss of confidence comes first, or central bank seigniorage, the other phase is ignited. In the case of rapid expansion of the money supply, prices rise rapidly in response to the increased supply of money relative to the supply of goods and services, and in the case of loss of confidence, the monetary authority responds to the risk premiums it has to pay by "running the printing presses."

Nevertheless the immense acceleration process that occurs during hyperinflation (such as during the German hyperinflation of 1922/23) still remains unclear and unpredictable. The transformation of an inflationary development into the hyperinflation has to be identified as a very complex phenomenon, which could be a further advanced research avenue of the complexity economics in conjunction with research areas like mass hysteria, bandwagon effect, social brain and mirror neurons.

The United States has avoided hyperinflation. It came close, however, during the Revolutionary War, when the revolutionary government churned out paper continentals to pay bills. The monthly inflation rate reached a peak of 47 percent in November 1779 (Bernholz 2003: 48). A second close encounter occurred during the Civil War, when the Union government printed greenbacks to finance the war effort. Inflation peaked at a monthly rate of 40 percent in March 1864 (Bernholz 2003: 107).

Many other cases of extreme social conflict encouraging hyperinflation can be seen, as in Germany after World War I, Hungary at the end of World War II and in Yugoslavia in the late 1980s just before break up of the country.

Less commonly, inflation may occur when there is debasement of the coinage: wherein are consistently shaved of some of their silver and gold, increasing the circulating medium and reducing the value of the currency. The "shaved" specie is then often restruck into coins with lower weight of gold or silver. Historical examples include Ancient Rome, China during the Song Dynasty, and the U.S. beginning in 1933. When "token" coins begin circulating, it is possible for the minting authority to engage in fiat creation of currency.

Much attention on hyperinflation naturally centres on the effect on savers whose investment become worthless. Academic economists seem not to have devoted much study on the (positive) effect on debtors. Interest rate changes often cannot keep up with hyperinflation or even high inflation, certainly with contractually fixed interest rates. (For example, in the 1970s in the United Kingdom inflation reached 25% per annum, yet interest rates did not rise above 15% - and then only briefly - and many fixed interest rate loans existed). Contractually there is often no bar to a debtor clearing his long term debt with "hyperinflated-cash" nor could a lender simply somehow suspend the loan. "Early redemption penalties" were (and still are) often based on a penalty of x months of interest/payment; again no real bar to paying off what had been a large loan. In interwar Germany, for example,much private and corporate debt was effectively wiped out; certainly for those holding fixed interest rate loans.

Since hyperinflation is visible as a monetary effect, models of hyperinflation center on the demand for money. Economists see both a rapid increase in the money supply and an increase in the velocity of money if the (monetary) inflating is not stopped. Either one, or both of these together are the root causes of inflation and hyperinflation. A dramatic increase in the velocity of money as the cause of hyperinflation is central to the "crisis of confidence" model of hyperinflation, where the risk premium that sellers demand for the paper currency over the nominal value grows rapidly. The second theory is that there is first a radical increase in the amount of circulating medium, which can be called the "monetary model" of hyperinflation. In either model, the second effect then follows from the first — either too little confidence forcing an increase in the money supply, or too much money destroying confidence.

In the confidence model, some event, or series of events, such as defeats in battle, or a run on stocks of the specie which back a currency, removes the belief that the authority issuing the money will remain solvent — whether a bank or a government. Because people do not want to hold notes which may become valueless, they want to spend them in preference to holding notes which will lose value. Sellers, realizing that there is a higher risk for the currency, demand a greater and greater premium over the original value. Under this model, the method of ending hyperinflation is to change the backing of the currency, often by issuing a completely new one. War is one commonly cited cause of crisis of confidence, particularly losing in a war, as occurred during Napoleonic Vienna, and capital flight, sometimes because of "contagion" is another. In this view, the increase in the circulating medium is the result of the government attempting to buy time without coming to terms with the root cause of the lack of confidence itself.

In the monetary model, hyperinflation is a positive feedback cycle of rapid monetary expansion. It has the same cause as all other inflation: money-issuing bodies, central or otherwise, produce currency to pay spiralling costs, often from lax fiscal policy, or the mounting costs of warfare. When businesspeople perceive that the issuer is committed to a policy of rapid currency expansion, they mark up prices to cover the expected decay in the currency's value. The issuer must then accelerate its expansion to cover these prices, which pushes the currency value down even faster than before. According to this model the issuer cannot "win" and the only solution is to abruptly stop expanding the currency. Unfortunately, the end of expansion can cause a severe financial shock to those using the currency as expectations are suddenly adjusted. This policy, combined with reductions of pensions, wages, and government outlays, formed part of the Washington consensus of the 1990s.

Whatever the cause, hyperinflation involves both the supply and velocity of money. Which comes first is a matter of debate, and there may be no universal story that applies to all cases. But once the hyperinflation is established, the pattern of increasing the money stock, by whichever agencies are allowed to do so, is universal. Because this practice increases the supply of currency without any matching increase in demand for it, the price of the currency, that is the exchange rate, naturally falls relative to other currencies. Inflation becomes hyperinflation when the increase in money supply turns specific areas of pricing power into a general frenzy of spending quickly before money becomes worthless. The purchasing power of the currency drops so rapidly that holding cash for even a day is an unacceptable loss of purchasing power. As a result, no one holds currency, which increases the velocity of money, and worsens the crisis.

That is, rapidly rising prices undermine money's role as a store of value, so that people try to spend it on real goods or services as quickly as possible. Thus, the monetary model predicts that the velocity of money will rise endogenously as a result of the excessive increase in the money supply. At the point when ordinary purchases are affected by inflation pressures, hyperinflation is out of control, in the sense that ordinary policy mechanisms, such as increasing reserve requirements, raising interest rates or cutting government spending will all be responded to by shifting away from the rapidly dwindling currency and towards other means of exchange.

During a period of hyperinflation, bank runs, loans for 24 hour periods, switching to alternate currencies, the return to use of gold or silver or even barter become common. Many of the people who hoard gold today expect hyperinflation, and are hedging against it by holding specie. There may also be extensive capital flight or flight to a "hard" currency such as the U.S. dollar. This is sometimes met with capital controls, an idea which has swung from standard, to anathema, and back into semi-respectability. All of this constitutes an economy which is operating in an "abnormal" way, which may lead to decreases in real production. If so, that intensifies the hyperinflation, since it means that the amount of goods in "too much money chasing too few goods" formulation is also reduced. This is also part of the vicious circle of hyperinflation.

Once the vicious circle of hyperinflation has been ignited, dramatic policy means are almost always required, simply raising interest rates is insufficient. Bolivia, for example, underwent a period of hyperinflation in 1985, where prices increased 12,000% in the space of less than a year. The government raised the price of gasoline, which it had been selling at a huge loss to quiet popular discontent, and the hyperinflation came to a halt almost immediately, since it was able to bring in hard currency by selling its oil abroad. The crisis of confidence ended, and people returned deposits to banks. The German hyperinflation (1919-Nov. 1923) was ended by producing a currency based on assets loaned against by banks, called the Rentenmark. Hyperinflation often ends when a civil conflict ends with one side winning. Although wage and price controls are sometimes used to control or prevent inflation, no episode of hyperinflation has been ended by the use of price controls alone. However, wage and price controls have sometimes been part of the mix of policies used to halt hyperinflation.

As noted, in countries experiencing hyperinflation, the central bank often prints money in larger and larger denominations as the smaller denomination notes become worthless. This can result in the production of some interesting banknotes, including those denominated in amounts of 1,000,000,000 or more.

One way to avoid the use of large numbers is by declaring a new unit of currency (an example being, instead of 10,000,000,000 Dollars, a bank might set 1 new dollar = 1,000,000,000 old dollars, so the new note would read "10 new dollars.") An example of this would be Turkey's revaluation of the Lira on 1 January 2005, when the old Turkish lira (TRL) was converted to the New Turkish lira (TRY) at a rate of 1,000,000 old to 1 new Turkish Lira. While this does not lessen the actual value of a currency, it is called redenomination or revaluation and also happens over time in countries with standard inflation levels. During hyperinflation, currency inflation happens so quickly that bills reach large numbers before revaluation.

Some banknotes were stamped to indicate changes of denomination. This is because it would take too long to print new notes. By time the new notes would be printed, they would be obsolete (that is, they would be of too low a denomination to be useful).

Metallic coins were rapid casualties of hyperinflation, as the scrap value of metal enormously exceeded the face value. Massive amounts of coinage were melted down, usually illicitly, and exported for hard currency.

Governments will often try to disguise the true rate of inflation through a variety of techniques. These can include the following:

None of these actions addresses the root causes of inflation and they, if discovered, tend to further undermine trust in the currency, causing further increases in inflation. Price controls will generally result in hoarding and extremely high demand for the controlled goods, resulting in shortages and disruptions of the supply chain. Products available to consumers may diminish or disappear as businesses no longer find it sufficiently profitable (or may be operating at a loss) to continue producing and/or distributing such goods, further exacerbating the problem.

Inflation rate is usually measured in percent per year. It can also be measured in percent per month or in price doubling time.

Often, at redenominations, three zeroes are cut from the bills. It can be read from the table that if the (annual) inflation is for example 100%, it takes 3.32 years to produce one more zero on the price tags, or 3 × 3.32 = 9.96 years to produce three zeroes. Thus can one expect a redenomination to take place about 9.96 years after the currency was introduced.

Western Europe, North America and many parts of Asia and Australasia have economies that depend a lot on computerized transaction procession of money transfers. However, most nations that are subject to hyperinfation risk have not done assessments as to the ability of the the electronic part of the finance system to remain intact under hyperinflation.

It is assumed (based upon IT practices for transnational processing that have evolved since the 1970s) that most money held by banks is not represented by 64 bit floating numbers. Under hyperinflation conditions most bank processing systems could fail due to overflow conditions .
