When prices are falling, consumers have an incentive to delay purchases and consumption until prices fall further, which in turn reduces overall economic activity. When purchases are delayed, productive capacity is idled and investment falls, leading to further reductions in [[aggregate demand]]. This is the deflationary spiral. The way to reverse this quickly would be to introduce an [[Stimulus (economic)|economic stimulus]]. The government could increase productive spending on things like infrastructure or the central bank could start expanding the [[money supply]].<ref name=":0" /> Deflation is also related to [[risk aversion]], where investors and buyers will start hoarding money because its value is now increasing over time.<ref name="Hussman2010">{{cite web | last1 = Hussman | first1 =John O. | title = Bernanke Leaps into a Liquidity Trap | year = 2010 | url = http://www.hussmanfunds.com/wmc/wmc101025.htm }}</ref> This can produce a [[liquidity trap]] or it may lead to shortages that entice investments yielding more jobs and commodity production. A central bank cannot, normally, charge negative interest for money, and even charging zero interest often produces less stimulative effect than slightly higher rates of interest. In a [[autarky|closed economy]], this is because charging zero interest also means having zero return on government securities, or even negative return on short maturities. In an open economy, it creates a [[Carry (investment)|carry]] trade and devalues the currency. A devalued currency produces higher prices for imports without necessarily stimulating exports to a like degree. Deflation is the natural condition of economies when the supply of money is fixed, or does not grow as quickly as population and the economy. When this happens, the available amount of hard currency per person falls, in effect making money more scarce, and consequently, the [[purchasing power]] of each unit of currency increases. Deflation also occurs when improvements in production [[efficiency]] lower the overall price of goods. [[Competition]] in the marketplace often prompts those producers to apply at least some portion of these cost savings into reducing the asking price for their goods. When this happens, consumers pay less for those goods, and consequently, deflation has occurred, since purchasing power has increased. Rising [[Productivity improving technologies (historical)|productivity]] and reduced transportation cost created structural deflation during the accelerated productivity era from 1870 to 1900, but there was mild inflation for about a decade before the [[Federal Reserve Act|establishment of the Federal Reserve]] in 1913.<ref name="Wells1890"/> There was inflation during [[World War I]], but deflation returned again after the war and during the 1930s depression. Most nations abandoned the [[gold standard]] in the 1930s so that there is less reason to expect deflation, aside from the collapse of speculative asset classes, under a [[Fiat money|fiat monetary system]] with low productivity growth. [[File:CPI 1914-2022.webp|thumb|alt=CPI 1914-2022|upright=1.8|American CPI 1914-2022{{legend|#0076BA |[[Inflation]]}} {{legend|#EE220C |Deflation}} {{legend-line|#1DB100 solid 3px|[[Money supply|M2 money supply]] increases year/year}} ]] In [[mainstream economics]], deflation may be caused by a combination of the supply and demand for goods and the supply and demand for money, specifically the supply of money going down and the supply of goods going up. Historic episodes of deflation have often been associated with the supply of goods going up (due to increased productivity) without an increase in the supply of money, or (as with the [[Great Depression]] and possibly Japan in the early 1990s) the demand for goods going down combined with a decrease in the money supply. Studies of the Great Depression by [[Ben Bernanke]] have indicated that, in response to decreased demand, the Federal Reserve of the time decreased the money supply, hence contributing to deflation. Causes include, on the demand side: * Growth deflation * Hoarding And on the supply side: * Bank credit deflation * Debt deflation * Decision on the money supply side * Credit deflation === Growth deflation=== Growth deflation is an enduring decrease in the real cost of goods and services as the result of technological progress, accompanied by competitive price cuts, resulting in an increase in aggregate demand.<ref>{{Cite journal |last1=Beckworth |first1=David |title=Aggregate Supply-Driven Deflation and Its Implications for Macroeconomic Stability |journal=Cato Journal |volume=28 |issue=3 |publisher=Cato Institute |url=http://www.cato.org/pubs/journal/cj28n3/cj28n3-1.pdf |url-status=dead |archive-url=https://web.archive.org/web/20111009235909/http://www.cato.org/pubs/journal/cj28n3/cj28n3-1.pdf |archive-date=2011-10-09 }}</ref> A structural deflation existed from the 1870s until the cycle upswing that started in 1895.

A historical analysis of money velocity and [[monetary base]] shows an inverse correlation: for a given percentage decrease in the [[monetary base]] the result is a nearly equal percentage increase in money velocity.<ref name="Hussman2010"/> This is to be expected because monetary base ({{math|{{var|M}}{{sub|{{var|B}}}})}}, [[velocity of money|velocity]] of base money ({{math|{{var|V}}{{sub|{{var|B}}}})}}, price level ({{mvar|P}}) and real output ({{mvar|Y}}) are related by definition: {{math|{{var|M}}{{sub|{{var|B}}}}{{mvar|V}}{{sub|{{var|B}}}} {{=}} {{var|P}}{{var|Y}}}}.<ref>{{cite book|title=Money Mischief: Episodes in Monetary History|last=Friedman|first=Milton|year=1994|publisher=Houghton Mifflin Harcourt|isbn=9780547542225 |pages=38}}</ref> However, the monetary base is a much narrower definition of money than [[M2 (economics)|M2 money supply]].

In a credit-based economy, a slow-down or fall in lending leads to less money in circulation, with a further sharp fall in money supply as confidence reduces and velocity weakens, with a consequent sharp fall-off in demand for employment or goods. The fall in demand causes a fall in prices as a supply [[Overproduction|glut]] develops. This becomes a deflationary spiral when prices fall below the costs of financing production, or repaying debt levels incurred at the prior price level. Businesses, unable to make enough profit no matter how low they set prices, are then liquidated. Banks get assets that have fallen dramatically in value since their mortgage loan was made, and if they sell those assets, they further glut supply, which only exacerbates the situation. To slow or halt the deflationary spiral, banks will often withhold collecting on non-performing loans ([[Economic history of Japan#Deflation from the 1990s to present|as in Japan]], and most recently America and Spain). This is often no more than a stop-gap measure, because they must then restrict credit, since they do not have money to lend, which further reduces demand, and so on. ====Historical examples of credit deflation==== In the early economic history of the United States, cycles of inflation and deflation correlated with capital flows between regions, with money being loaned from the financial center in the Northeast to the commodity producing regions of the (mid)-West and South. In a [[procyclical]] manner, prices of commodities rose when capital was flowing in, that is, when banks were willing to lend, and fell in the depression years of 1818 and 1839 when banks called in loans.<ref name="North1966"> {{cite book |title = The Economic Growth of the United States 1790–1860 |last = North |first = Douglas C. |year = 1966 |publisher = W.

Most money circulated as banknotes, which typically sold at a discount according to distance from the issuing bank and the bank's perceived financial strength. When banks failed their notes were redeemed for bank reserves, which often did not result in payment at [[par value]], and sometimes the notes became worthless. Notes of weak surviving banks traded at steep discounts.<ref name="David Ginsburg"/><ref name="Taylor 1951"/> During the Great Depression, people who owed money to a bank whose deposits had been frozen would sometimes buy bank books (deposits of other people at the bank) at a discount and use them to pay off their debt at par value.<ref>Benjamin Roth, ed. James Ledbetter and Daniel B. Roth, ''The Great Depression: A Diary''. Perseus Books, 2009, p. 36. "A market for buying bank 'passbooks' also cropped up in places like Youngstown. If you were desperate enough in 1931 for money to buy basic necessities, you could get 60 to 70 cents on the dollar for your passbooks' value. Local newspapers even printed the weekly rates for buying and selling these passbooks as they became a commodity; Roth pasted one such rate chart into his diary."</ref> Deflation occurred periodically in the U.S. during the 19th century (the most important exception was during the Civil War). This deflation was at times caused by technological progress that created significant economic growth, but at other times it was triggered by [[Financial crisis#19th century|financial crises]] – notably the [[Panic of 1837]] which caused deflation through 1844, and the [[Panic of 1873]] which triggered the [[Long Depression]] that lasted until 1879.<ref name="Wells1890"/><ref name="Taylor 1951"/><ref name="North1966"/> These deflationary periods preceded the establishment of the U.S. [[Federal Reserve System]] and its active management of monetary matters. Episodes of deflation have been rare and brief since the Federal Reserve was created (a notable exception being the [[Great Depression]]) while U.S. economic progress has been unprecedented. A financial crisis in England in 1818 caused banks to call in loans and curtail new lending, draining specie out of the U.S.{{citation needed|date=February 2021}} The Bank of the United States also reduced its lending. Prices for cotton and tobacco fell. The price of agricultural commodities also was pressured by a return of normal harvests following 1816, the ''[[year without a summer]]'', that caused large scale famine and high agricultural prices.<ref>{{Harvnb|Taylor|1951|pp=336}}</ref> There were several causes of the deflation of the severe depression of 1839–1843, which included an oversupply of agricultural commodities (importantly cotton) as new cropland came into production following large federal land sales a few years earlier, banks requiring payment in gold or silver, the failure of several banks, default by several states on their bonds and British banks cutting back on specie flow to the U.S.<ref name="North1966"/><ref>{{cite web | last1 = Wallis | first1 = Hohn Joseph | last2 = National Bureau of Economic Research | title = The Depression of 1839 to 1843 | url = http://www.startabank.com/history/200809_TheDepression/depression1839.pdf }}</ref> This cycle has been traced out on a broad scale during the [[Great Depression]]. Partly because of overcapacity and market saturation and partly as a result of the [[Smoot–Hawley Tariff Act]], international trade contracted sharply, severely reducing demand for goods, thereby idling a great deal of capacity, and setting off a string of bank failures.<ref name="Beaudreau1996" /> A similar situation in Japan, beginning with the stock and real estate market collapse in the early 1990s, was arrested by the Japanese government preventing the collapse of most banks and taking over direct control of several in the worst condition. ===Scarcity of official money=== The United States had no national paper money until 1862 ([[Greenback (money)|greenbacks]] used to fund the Civil War), but these notes were discounted to gold until 1877. There was also a shortage of U.S. minted coins. Foreign coins, such as Mexican silver, were commonly used.<ref name="David Ginsburg"/> At times banknotes were as much as 80% of currency in circulation before the Civil War. In the financial crises of 1818–19 and 1837–1841, many banks failed, leaving their money to be redeemed below [[par value]] from reserves. Sometimes the notes became worthless, and the notes of weak surviving banks were heavily discounted.<ref name="Taylor 1951"/> The Jackson administration opened branch mints, which over time increased the supply of coins. Following the 1848 finding of gold in the [[Sierra Nevada (U.S.)|Sierra Nevada]], enough gold came to market to devalue gold relative to silver. To equalize the value of the two metals in coinage, the US mint slightly reduced the silver content of new coinage in 1853.<ref name="David Ginsburg"/> When structural deflation appeared in the years following 1870, a common explanation given by various government inquiry committees was a scarcity of gold and silver, although they usually mentioned the changes in industry and trade we now call productivity. However, [[David Ames Wells|David A. Wells]] (1890) notes that the U.S. money supply during the period 1879-1889 actually rose 60%, the increase being in gold and silver, which rose against the percentage of national bank and legal tender notes. Furthermore, Wells argued that the deflation only lowered the cost of goods that benefited from recent improved methods of manufacturing and transportation. Goods produced by craftsmen did not decrease in price, nor did many services, and the cost of labor actually increased. Also, deflation did not occur in countries that did not have modern manufacturing, transportation and communications.<ref name="Wells1890">{{cite book |title=Recent Economic Changes and Their Effect on Production and Distribution of Wealth and Well-Being of Society |last=Wells |first=David A. |year=1890 |publisher= D.

[[William Stanley Jevons]] predicted rising gold supply would cause inflation decades before it actually did. [[Irving Fisher]] blamed the worldwide inflation of the pre-WWI years on rising gold supply.<ref> {{cite book |title=The Cost of Living in America: A Political History of Economic Statistics, 1880–2000 |last=Stapleford |first= Thomas |year=2009|publisher=Cambridge University Press |pages=69–73}} </ref> In economies with an unstable currency, barter and other alternate currency arrangements such as [[dollarization]] are common, and therefore when the 'official' money becomes scarce (or unusually unreliable), commerce can still continue (e.g., most recently in [[Hyperinflation in Zimbabwe|Zimbabwe]]). Since in such economies the central government is often unable, even if it were willing, to adequately control the internal economy, there is no pressing need for individuals to acquire official currency except to pay for imported goods. ===Currency pegs and monetary unions=== If a country [[currency peg|pegs]] its currency to one of another country that features a higher [[productivity growth]] or a more favourable [[unit cost]] development, it must – to maintain its competitiveness – either become equally more productive or lower its [[factor prices]] (e.g., wages). Cutting factor prices fosters deflation. [[Monetary union]]s have a similar effect to currency pegs. ==Effects== {{More citations needed|section|date=September 2022}} === On spending and borrowing === Some believe that, in the absence of large amounts of debt, deflation would be a welcome effect because the lowering of prices increases [[purchasing power]].<ref>{{cite journal| last =Selgin| first =George| title =Less Than Zero: The Case for a Falling Price Level in a Growing Economy| journal =IEA Hobart Paper| volume =32| page =87| publisher =[[Institute of Economic Affairs]]| location =London| date =1997| url =http://www.iea.org.uk/sites/default/files/publications/files/upldbook98pdf.pdf| issn =0073-2818| access-date =4 December 2014 }}</ref> However, while an increase in the purchasing power of one's money benefits some, it amplifies the sting of debt for others: after a period of deflation, the payments to service a debt represent a larger amount of purchasing power than they did when the debt was first incurred. Consequently, deflation can be thought of as an effective increase in a loan's interest rate. If, as during the [[Great Depression]] in the United States, deflation averages 10% per year, even an interest-free loan is unattractive as it must be repaid with money worth 10% more each year. Under normal conditions, most central banks, such as the Federal Reserve, implement policy by setting a target for a short-term interest rate{{snd}} the overnight [[federal funds rate]] in the U.S.{{snd}} and enforcing that target by buying and selling securities in open capital markets. When the short-term interest rate hits zero, the central bank can no longer ease policy by lowering its usual interest-rate target. With interest rates near zero, [[debt relief]] becomes an increasingly important tool in managing deflation. In recent times, as loan terms have grown in length and loan financing (or leveraging) is common among many types of investments, the costs of deflation to borrowers has grown larger. === On savings and investments === Deflation can discourage private investment, because there is reduced expectations on future profits when future prices are lower. Consequently, with reduced private investments, [[#Deflationary spiral|spiraling deflation]] can cause a collapse in [[aggregate demand]]. Without the "hidden risk of inflation", it may become more prudent for institutions to hold on to money, and not to spend or invest it (burying money). They are therefore rewarded by [[saving]] and holding money. This "hoarding" behavior is seen as undesirable by most economists.{{citation needed|reason=Hayek's word alone is not a reliable source regarding what most economists think, especially when he was writing in 1932.

In this sense, its effects are the opposite of inflation, the effect of which is to transfer wealth from currency holders and lenders (savers) and to borrowers, including governments, and cause overinvestment. Whereas inflation encourages short term consumption and can similarly overstimulate investment in projects that may not be worthwhile in real terms (for example, the [[Dot-com bubble|dot-com]] and [[Real estate bubble|housing bubble]]s), deflation reduces investment even when there is a real-world demand not being met. In modern economies, deflation is usually associated with economic depression, as occurred in the [[Great Depression]] and the [[Long Depression]].

Another related idea is [[Irving Fisher]]'s theory that [[Debt deflation|excess debt can cause a continuing deflation]]. ==Counteracting deflation== During severe deflation, targeting an interest rate (the usual method of determining how much currency to create) may be ineffective, because even lowering the short-term interest rate to zero may result in a real interest rate which is too high to attract credit-worthy borrowers. In the 21st-century, negative interest rates have been tried, but it cannot be too negative, since people might withdraw cash from bank accounts if they have a negative interest rate. Thus the central bank must directly set a target for the quantity of money (called "[[quantitative easing]]") and may use extraordinary methods to increase the supply of money, e.g. purchasing financial assets of a type not usually used by the central bank as reserves (such as [[Mortgage-backed security|mortgage-backed securities]]). Before he was [[Chairman of the Federal Reserve|Chairman]] of the United States [[Federal Reserve System|Federal Reserve]], [[Ben Bernanke]] claimed in 2002, "sufficient injections of money will ultimately always reverse a deflation",<ref>[http://www.federalreserve.gov/BOARDDOCS/SPEECHES/2002/20021121/default.htm "Deflation: Making Sure 'It' Doesn't Happen Here"] {{Webarchive|url=https://web.archive.org/web/20081024060408/http://www.federalreserve.gov/BOARDDOCS/SPEECHES/2002/20021121/default.htm |date=2008-10-24 }}.

Federal Reserve.</ref> although Japan's deflationary spiral was not broken by the amount of quantitative easing provided by the Bank of Japan. Until the 1930s, it was commonly believed by [[classical economists|economists]] that deflation would cure itself. As prices decreased, demand would naturally increase, and the economic system would correct itself without outside intervention. This view was challenged in the 1930s during the [[Great Depression]]. [[Keynesian economics|Keynesian economists]] argued that the economic system was not self-correcting with respect to deflation and that governments and central banks had to take active measures to boost demand through tax cuts or increases in government spending. Reserve requirements from the central bank were high compared to recent times. So were it not for redemption of currency for gold (in accordance with the gold standard), the central bank could have effectively increased money supply by simply reducing the reserve requirements and through [[open market operations]] (e.g., buying treasury bonds for cash) to offset the reduction of money supply in the private sectors due to the collapse of credit (credit is a form of money). With the rise of [[monetarism|monetarist]] ideas, the focus in fighting deflation was put on expanding demand by lowering interest rates (i.e., reducing the "cost" of money). This view has received criticism in light of the failure of accommodative policies in both Japan and the US to spur demand after stock market shocks in the early 1990s and in 2000–2002, respectively. [[Austrian economists]] worry about the inflationary impact of monetary policies on asset prices. Sustained low real rates can cause higher asset prices and excessive debt accumulation. Therefore, lowering rates may prove to be only a temporary palliative, aggravating an eventual debt deflation crisis. ===Special borrowing arrangements=== When the central bank has lowered nominal interest rates to zero, it can no longer further stimulate demand by lowering interest rates. This is the famous [[liquidity trap]]. When deflation takes hold, it requires "[[quantitative easing|special arrangements]]" to lend money at a zero nominal rate of interest (which could still be a very high ''real'' rate of interest, due to the ''negative'' inflation rate) in order to artificially increase the money supply. === Capital === Although the values of [[capital asset]]s are often casually said to deflate when they decline, this usage is not consistent with the usual definition of deflation; a more accurate description for a decrease in the value of a capital asset is [[Depreciation (economics)|economic depreciation]]. Another term, the [[depreciation|accounting conventions of depreciation]] are standards to determine a decrease in values of capital assets when market values are not readily available or practical. ==Historical examples== === EU countries === The inflation rate of [[Greece]] was negative during three years from 2013 to 2015.

The Bulgarian currency, the [[Bulgarian lev|lev]], is [[currency peg|pegged]] to the [[Euro]] with a fixed exchange rate.

When real estate values dropped, these loans could not be paid. The banks could try to collect on the collateral (land), but this wouldn't pay off the loan. Banks delayed that decision, hoping asset prices would improve. These delays were allowed by national banking regulators. Some banks made even more loans to these companies that are used to service the debt they already had. This continuing process is known as maintaining an "unrealized loss", and until the assets are completely revalued and/or sold off (and the loss realized), it will continue to be a deflationary force in the economy. Improving bankruptcy law, land transfer law, and tax law have been suggested as methods to speed this process and thus end the deflation.<ref>{{Cite web|last=Group|first=Global Legal|title=International Comparative Legal Guides|url=https://iclg.com/practice-areas/restructuring-and-insolvency-laws-and-regulations/japan|access-date=2021-02-04|website=International Comparative Legal Guides International Business Reports|language=en}}</ref><ref>{{Cite web|title=Practical Law UK Signon|url=https://signon.thomsonreuters.com/?productid=PLCUK&viewproductid=UKPL&lr=0&culture=en-GB&returnto=https%3a%2f%2fuk.practicallaw.thomsonreuters.com%2fCosi%2fSignOn%3fredirectId%3drt_a4870076-2703-4605-97ff-f08574fb3b5b&tracetoken=0204210942140CvCsgoHJiMwaBw39XiWjYkZf7BuLWKhdD4IKQLRqkuKTNqq0uY7L-SNnb6hW5HJa_sHPQSMcrBJvtle0FRWi-kHms5dRA6MV8ZxXPCuxInbgcBE3ulPDB2z7jH1JUsZlNV_soxJ41jUzrYlUcZ7KaQ8YvWfzC2AXiVHYTeGKljRk8Bf2NxoS7YZVRmexAcKyWC8dnsRYP0pDDfB_ChO0JlUZykNMghFRGv-ye4yf3PPTtEMKJEh8jgl_D3s0C1zCeYs8Sq4HgQxBjl5XvbbK0YqbM7cru3kAM6t9DMvOVqcwdqzT3rq99Oc8xou-BUuB_KnlWcGfZFt6jFLkw2cta7S9D9F-eUxOzifxbSqBOrMjeC5Eza68vFPFsUV1IvRG|access-date=2021-02-04|website=signon.thomsonreuters.com}}</ref><ref>{{Cite web|date=2021-01-13|title=Japan's 2020 corporate bankruptcies fall to 31-year low with government aid|url=https://www.japantimes.co.jp/news/2021/01/13/business/corporate-business/japans-2020-corporate-bankruptcies-fall-to-31-year-low-government-aid/|access-date=2021-02-04|website=The Japan Times|language=en-US}}</ref><ref>{{Cite news|date=2002-05-09|title=Prize possessions|newspaper=The Economist|url=https://www.economist.com/finance-and-economics/2002/05/09/prize-possessions|access-date=2021-02-04|issn=0013-0613}}</ref><ref>{{Cite news|date=2020-09-24|title=What to do about zombie firms|newspaper=The Economist|url=https://www.economist.com/leaders/2020/09/24/what-to-do-about-zombie-firms|access-date=2021-02-04|issn=0013-0613}}</ref> * Insolvent banks: Banks with a larger percentage of their loans which are "non-performing", that is to say, they are not receiving payments on them, but have not yet written them off, cannot lend more money; they must increase their cash reserves to cover the bad loans.<ref>{{Cite web|title=Is the Bank of Japan Technically Insolvent?

When the pound was returned to the gold standard after the war it was done on the basis of the pre-war gold price, which, since it was higher than equivalent price in gold, required prices to fall to realign with the higher target value of the pound. The UK experienced deflation of approximately 10% in 1921, 14% in 1922, and 3 to 5% in the early 1930s.<ref>Bank of England Quarterly inflation report Feb 2009 p. 33 chart A</ref> ===United States=== [[Image:US Historical Inflation Ancient.svg|thumb|upright=1.8|right|Annual inflation (in blue) and deflation (in green) rates in the [[United States]] since 1666]] [[Image:US Consumer Price Index Graph.svg|thumb|upright=1.8|right|[[United States Consumer Price Index|US CPI-U]] starting from 1913. Source: U.S. Department of Labor]] ====Major deflations in the United States==== There have been four significant periods of deflation in the United States. The first and most severe was during the depression in 1818–1821 when prices of agricultural commodities declined by almost 50%. A credit contraction caused by a financial crisis in England drained specie out of the U.S. The Bank of the United States also contracted its lending. The price of agricultural commodities fell by almost 50% from the high in 1815 to the low in 1821, and did not recover until the late 1830s, although to a significantly lower price level. Most damaging was the price of cotton, the U.S.'s main export. Food crop prices, which had been high because of the famine of 1816 that was caused by the [[year without a summer]], fell after the return of normal harvests in 1818. Improved transportation, mainly from turnpikes, and to a minor extent the introduction of steamboats, significantly lowered transportation costs.<ref name="Taylor 1951">{{cite book |title=The Transportation Revolution, 1815–1860 |last=Taylor |first= George Rogers |year=1951 |publisher = Rinehart & Co. |location=New York |volume=IV |series=The Economic History of the United States |isbn= 978-0-87332-101-3 |pages=133, 331–334 |url=https://books.google.com/books?id=qjbLCQAAQBAJ&pg=PP1}} </ref> The second was the depression of the late 1830s to 1843, following the [[Panic of 1837]], when the currency in the United States contracted by about 34% with prices falling by 33%.

This "deflation" satisfies both definitions, that of a decrease in prices and a decrease in the available quantity of money. Despite the deflation and depression, GDP rose 16% from 1839 to 1843.<ref name="Atack1994"/> The third was after the [[United States Civil War|Civil War]], sometimes called [[The Great Deflation]]. It was possibly spurred by return to a gold standard, retiring paper money printed during the Civil War: {{blockquote|The Great Sag of 1873–96 could be near the top of the list. Its scope was global. It featured cost-cutting and productivity-enhancing technologies. It flummoxed the experts with its persistence, and it resisted attempts by politicians to understand it, let alone reverse it. It delivered a generation's worth of rising bond prices, as well as the usual losses to unwary creditors via defaults and early calls. Between 1875 and 1896, according to [[Milton Friedman]], prices fell in the United States by 1.7% a year, and in Britain by 0.8% a year. |source=''Grant's Interest Rate Observer'', 10 March 2006<ref>{{cite web |title=Inflation, ho!

The deflation of the Great Depression occurred partly because there was an enormous contraction of [[Credit (finance)|credit]] (money), [[bankruptcies]] creating an environment where [[monetary base|cash]] was in frantic demand, and when the [[Federal Reserve]] was supposed to accommodate that demand, it instead contracted the money supply by 30% in enforcement of its new [[real bills doctrine]], so banks failed one by one (because they were unable to meet the sudden demand for cash{{snd}}see [[Bank run]]). From the standpoint of the [[Fisher equation]] (see above), there was a simultaneous drop both in money supply (credit) and the [[velocity of money]] which was so profound that price deflation took hold despite the increases in money supply spurred by the Federal Reserve. ====Minor deflations in the United States==== Throughout the history of the United States, inflation has approached zero and dipped below for short periods of time. This was quite common in the 19th century, and in the 20th century until the permanent abandonment of the gold standard for the [[Bretton Woods system]] in 1948. In the past 60 years, the United States has experienced deflation only two times; in 2009 with the Great Recession and in 2015, when the CPI barely broke below 0% at −0.1%.<ref>{{cite news |first=Yuval |last=Rosenberg |title=America Is In Deflation.

Consumer prices dropped 1 percent in October 2008. This was the largest one-month fall in prices in the U.S. since at least 1947. That record was again broken in November 2008 with a 1.7% decline. In response, the [[Federal Reserve]] decided to continue cutting interest rates, down to a near-zero range as of December 16, 2008.<ref>{{cite press release |title=FOMC statement |publisher=Board of Governors of the Federal Reserve System |date=16 December 2008 |url=http://www.federalreserve.gov/newsevents/press/monetary/20081216b.htm}}</ref> In late 2008 and early 2009, some economists feared the U.S. would enter a deflationary spiral.
