Hungary’s 1946 Hyperinflation

The Worst Inflation in History and the Fall of the Pengő

Post-War Chaos and the Seeds of Hyperinflation

In the aftermath of World War II, Hungary’s economy was in ruins. The war had obliterated roughly 40% of the nation’s wealth, with an estimated 80% of the capital city, Budapest, left destroyed. Infrastructure was shattered – nearly half of rail lines were wrecked and many factories lay in rubble. On top of this physical devastation, Hungary was burdened with hefty war reparations (pledged at $300 million to the Soviets, among others) and the ongoing costs of Soviet occupation. The occupying Red Army not only confiscated resources and goods as “compensation,” but even issued its own unbacked pengő currency in occupied areas, which flooded the money supply and aggravated inflation.

Politically, the post-war Hungarian government was weak and split. A “coalition” government in 1945–46 struggled to govern alongside the Soviet-backed Communists, and effective taxation was nearly impossible amid the chaos. With tax revenues unable to cover war costs and reparations, the government resorted to printing money on an unprecedented scale. Some historians even argue that the Soviet authorities deliberately abetted Hungary’s monetary collapse to wipe out the middle class and destabilize the economy for political ends. Whether by necessity or design, all the ingredients for runaway inflation were in place: massive economic loss, huge external obligations, a shattered tax base, and uncontrolled paper money issuance.


The Pengő’s Collapse: From Inflation to Hyperinflation

In 1945, prices in Hungary began rising rapidly – and then explosively. What started as high inflation soon snowballed into the worst hyperinflation in recorded history. By July 1946, Hungary’s inflation rate reached 4.19×1016% for the month (41.9 quadrillion percent). In practical terms, prices were doubling about every 15 hours during that month. For comparison, even Zimbabwe’s notorious 2008 hyperinflation never quite surpassed this record, and Weimar Germany’s 1923 episode was orders of magnitude milder. Hungarian inflation in mid-1946 was so extreme that whatever a person had in their pocket in the morning would lose half its buying power by the evening.

Peak Hyperinflation Comparison

Country Period Peak Monthly Rate Prices Doubled Every Highest Denomination
Hungary July 1946 4.19 × 1016 % 15.6 hours 1020 pengő (100 quintillion)
Zimbabwe Nov 2008 7.96 × 1010 % 24.7 hours 1014 dollars (100 trillion)
Weimar Germany Oct 1923 29,500% 3.7 days 1014 marks (100 trillion)

Several attempts were made to slow the inflation, but none succeeded. In late 1945 the government imposed a steep 75% “capital levy” tax on wealth, requiring citizens to buy stamps worth triple a banknote’s value and affix them to high-denomination pengő notes. Unstamped notes became nearly worthless. This one-time tax temporarily reduced the money in circulation, but inflation resumed its upward spiral soon after.

The authorities also tried to simplify accounting amidst the torrent of zeros by introducing new unit names for the currency. After the pengő had lost too much value to count, the government issued notes denominated in milpengő (short for millió pengő, or one million pengő) and later in b.-pengő (short for billió pengő, or one trillion pengő on the long scale). These were not new currencies but rather naming conventions to cut down the length of numbers.

Understanding the Denomination Shorthand

Shorthand Meaning Equivalent in Pengő
1 milpengő Millió pengő (million pengő) 1,000,000 pengő
1 b.-pengő Billió pengő (trillion pengő, long scale) 1,000,000,000,000 pengő
100 million b.-pengő Largest denomination ever circulated 100,000,000,000,000,000,000 pengő (1020)
1 milliárd b.-pengő Printed but never circulated 1,000,000,000,000,000,000,000 pengő (1021)

This convention allowed the re-use of printing plates with just a color change and a new label instead of designing entirely new banknotes for every extra zero. Despite these efforts, the value of the pengő continued to plummet at a dizzying pace.

By mid-1946 the numbers became mind-boggling. In July 1946, the Hungarian National Bank issued the 100 million B.-pengő banknote, the largest denomination ever actually circulated in the country. This single bill was emblazoned “100,000,000 B.-Pengő,” which equaled 100 quintillion pengő (1020 pengő) in ordinary terms. It holds the grim record of being the highest denomination banknote ever issued for circulation in the world. Even higher notes were printed in Hungary – a 1 “milliárd” B.-pengő worth 1021 pengő, i.e. one sextillion pengő – but that note never made it into circulation. Tellingly, when the 100 million B.-pengő note was released in July 1946, its purchasing power was only about USD $0.20 in real value. In other words, a quintillion pengő could hardly buy a candy bar.

Speed of Denomination Escalation

Date Highest Note in Circulation Value in Pengő
April 1946 10,000 milpengő 1010 pengő
June 1946 1,000,000 milpengő 1012 pengő
July 1946 100,000,000 b.-pengő 1020 pengő

Banknotes literally rushed out of the printers and into the streets, often with only weeks (or days!) between successive issues. Citizens eventually stopped referring to money by its face value – the numbers were too large to keep straight – and instead identified banknotes by their color or design. For example, people might ask for “a blue note” or pay with “two reds,” since saying “100 trillion pengő” or “one quintillion pengő” had become almost meaningless in daily life.


The Adópengő: A Temporary Lifeline for a Failing Currency

Amid the currency free-fall, the Hungarian government introduced a parallel currency known as the adópengő (meaning “tax pengő”) in an attempt to stabilize daily transactions. Launched on 1 January 1946, the adópengő was originally an indexed unit of account – a way to quote prices and salaries in more stable terms by adjusting its value daily against the pengő. Initially, 1 adópengő was defined equal to 1 pengő. But with inflation roaring, the government would announce a new conversion rate each day (often via radio broadcasts) to keep the adópengő’s value roughly in line with prices.

For a few months, this strategy provided a modicum of stability. However, as the pace of inflation accelerated, even the adópengő couldn’t hold value. The exchange rate of adópengő to pengő had to be raised exponentially:

The Adópengő’s Accelerating Collapse

Date 1 Adópengő Equaled
January 1, 1946 1 pengő
May 1, 1946 630 pengő
July 1, 1946 7,500,000,000 pengő (7.5 billion)
July 10, 1946 2 × 1021 pengő (2 sextillion)

In essence, the adópengő was inflating almost as fast as the pengő – just with a slight lag. Beginning in late May 1946, the Ministry of Finance started issuing adópengő paper bills (essentially tax credit certificates) in denominations from 10,000 up to 100,000,000 adópengő. These simple, low-quality notes were soon declared legal tender and circulated alongside pengő notes. By the final months of hyperinflation, prices were commonly quoted in adópengő rather than pengő, since the regular pengő figures had become unmanageably huge. In fact, adópengő notes almost completely replaced pengő in daily use by July 1946.

One side effect of the adópengő scheme was practical: the enormous quantity of paper required to print all those tax notes caused a shortage of quality paper stock in Hungary. Ironically, this paper shortage impeded the printing of the new currency (forint) notes that were planned to end the crisis. By July 1946, it was evident that only a radical currency reform could restore confidence. The pengő – once a proud and stable currency in the interwar years – was effectively dead.


Everyday Life During Hungary’s Hyperinflation

For ordinary Hungarians, daily life in 1945–46 was nightmarish. The pengő’s collapse wiped out the savings of an entire generation. People who had stored wealth in cash (as many did, since the pengő had been a trusted currency in the 1930s) saw those life savings become worthless virtually overnight. Middle-class families that had scrimped and saved were suddenly destitute. Everyone became a pauper at roughly the same time – a traumatizing experience that Hungarians summed up as “when money died.”

As cash lost its value by the hour, normal commerce broke down. A barter economy sprang up in its place. Goods became the true currency: city-dwellers would travel to the countryside lugging whatever valuables they had left – clothing, linens, jewelry, even porcelain – to trade for food. Farmers, understandably, refused to sell food for paper pengő that might be worthless the next day; they wanted tangible goods in return. Markets turned into swap meets where a pair of boots might be exchanged for a sack of potatoes.

The Price of Bread During the Crisis

Date Cost of One Loaf of Bread
August 1945 6 pengő
May 1946 8,000,000 pengő
June 1946 5,850,000,000 pengő (5.85 billion)

This barter system was inefficient and often inequitable, but it was the only way to survive when the national currency was “not worth the paper it’s printed on.” Indeed, photos from the time show banknotes being used as fuel for fires or as wallpaper, since they were more plentiful than actual fuel and cheaper than blank paper. One striking image from 1946 shows a woman lighting her cigarette with a torch of pengő notes – a poignant demonstration that the money had more value as kindling than as currency.

Workers’ wages lagged hopelessly behind prices, despite employers increasing pay sometimes daily or even more frequently. Many employers resorted to paying workers in kind (with food or goods) or in adópengő tax bills, since cash was essentially useless. Pensions and fixed incomes were obliterated – by the time pensioners received their check and went to buy groceries, the prices had doubled or tripled.

Public services and businesses struggled to function. Shop owners couldn’t keep up with repricing goods every few hours, and many shops simply closed down. Restaurant menus were often left without prices listed, or prices were adjusted between a customer ordering and paying. Train fares and postage stamps were adjusted constantly; eventually the postal service started overprinting stamps with new, higher values, just as the bank had overprinted currency.

In such chaos, daily life was reduced to a frantic race to spend money as soon as one got it. There was a popular saying: “Spend your pengő before it loses its value by sundown.” People would literally run from their workplace on payday to the shops to purchase anything of real value (food, clothes, tools) immediately, because waiting even a day meant the cash would buy far less.

Socially, the hyperinflation was a great leveler – it erased distinctions between rich and poor (aside from those with hard assets or gold). Everyone was equally desperate, queueing up with bags or even wheelbarrows full of notes for the simplest groceries. Yet, remarkably, despite the desperation, Hungarian society remained largely orderly. Still, the psychological toll was immense. Confidence in government and the financial system was shattered. As one Hungarian later recalled, “we had to learn that money can die, and when it does, pieces of paper are no substitute for bread.”


Stabilization: The Forint Ends the Crisis

By the summer of 1946, the only solution to this economic death spiral was currency stabilization and a complete reset. On August 1, 1946, the Hungarian government replaced the pengő with a new currency, the forint. The conversion rate was set at 1 forint = 400 octillion pengő (4×1029 pengő). In other words, 400,000,000,000,000,000,000,000,000,000 old pengő = 1 forint.

The Currency Reset in Numbers

Conversion Rate 1 forint = 4 × 1029 pengő (400 octillion)
Zeros Dropped 29
Total Pengő in Circulation (July 1946) ~7.6 × 1025 pengő
Value of All Pengő in Circulation 0.19 forint (a few U.S. cents)
Gold Backing 13.21 forints per gram of gold

This astounding exchange rate effectively acknowledged the pengő’s utter collapse. To put it another way, all the pengő cash in circulation in mid-July 1946 was converted into only about 0.19 forint in total value. The entire money stock of the country became worth less than one-fifth of a forint.

The government’s stabilization program did more than just introduce a new currency. It was a comprehensive plan that included drastic fiscal and monetary reforms. Key steps included: halting the printing presses to stop any further increase in money supply; instituting new taxes (and enforcing collection) to cover government spending without inflation; and securing as much backing for the new currency as possible. The National Bank accumulated whatever hard assets it could – including recalling gold reserves that had been evacuated abroad during the war – to build confidence in the forint.

Prices were immediately reined in once the forint was introduced – and critically, people believed in the forint, something that could no longer be said of the pengő. With a strict limitation on forint issuance and newfound fiscal discipline, inflation fell to normal levels by late 1946, effectively ending the nightmare. The hyperinflation had lasted barely a year, but its impact would scar Hungary’s economy and psyche for decades.


Comparing Hungary’s Hyperinflation to Weimar Germany and Zimbabwe

Hungary’s 1945–46 currency collapse often invites comparison to other famous hyperinflations, especially Weimar Germany (1923) and Zimbabwe (2007–2009). All three episodes shared the common feature of paper money overproduction amid economic collapse, but there were important differences in causes and outcomes.

Hyperinflation Comparison: Causes, Severity & Outcomes
Factor Hungary (1946) Weimar Germany (1923) Zimbabwe (2008)
Root Cause WWII devastation, Soviet reparations, possible deliberate destabilization by occupying forces WWI reparations, government debt, printing money to fund Ruhr strike support Peacetime mismanagement, land redistribution destroying agriculture, Congo War spending
Peak Rate 4.19 × 1016% monthly 29,500% monthly 7.96 × 1010% monthly
Highest Note 1020 pengő (circulated) / 1021 (printed) 1014 marks 1014 dollars
Resolution Forint introduced Aug 1, 1946 (still in use today) Rentenmark introduced Nov 1923, backed by land values Dollar abandoned Apr 2009, adopted USD/ZAR for transactions
Political Aftermath Communists consolidated power, portrayed themselves as economic saviors Social unrest contributed to conditions enabling the rise of the Nazi party Ruling regime retained power but with significant reputational damage

Despite differences, a common thread among these episodes is that once hyperinflation starts feeding on itself, drastic action – essentially a currency reset – is the only way out. And in each case, the notes from those periods have transitioned into the collectibles market, where they are actively traded as tangible reminders of the frailty of monetary systems.


Collecting Hyperinflation Banknotes: Pengő and Adópengő Today

For today’s currency collectors and history enthusiasts, the banknotes of the Hungarian hyperinflation offer a fascinating window into this dramatic era. What was once nearly discarded “hyperinflated money” is now sought after as historical collectibles. In particular, the highest-denomination B-pengő notes of 1946 and the peculiar adópengő tax notes attract significant interest. Collectors are drawn to them not for their original face value, but for their historical significance, novelty, and scarcity in good condition.

Key Considerations for Collectors
Factor What Collectors Should Know
Historical Significance Every pengő or adópengő note from 1945–46 tells a story of economic collapse. Owning a 100 million B.-pengő note – the largest denomination ever circulated – is like holding a world record in your hand. These notes are tangible artifacts of the worst inflation in history, and serve as educational pieces about monetary policy gone awry.
Scarcity & Condition Despite the trillions printed, finding these notes in excellent condition can be challenging. During the inflation, people handled notes roughly or carried them in huge bundles, and most were discarded or destroyed after the forint conversion. High denominations in pristine uncirculated condition are far scarcer. The 1 milliárd B-pengő (one sextillion pengő) was never circulated, and surviving specimens are exceedingly rare. Notes with crisp paper, bright colors, and no folds command a premium.
PMG-Graded Examples Many serious collectors seek notes that have been professionally graded and encapsulated by services like PMG (Paper Money Guaranty). It’s not uncommon to see Hungarian hyperinflation notes with high grades given their short circulation period. For instance, an uncirculated 1946 1 Milliárd B.-Pengő graded PMG 64 Choice Uncirculated is an exceptional piece of hyperinflation history. Some collectors also enjoy notes with the Planet Banknote exclusive PMG Pedigree Label, indicating they came from a notable source or collection.
Collector Demand The market for hyperinflation notes is global. Hungarian pengő notes, much like Zimbabwe dollars or Weimar marks, have a broad appeal – they attract banknote specialists, casual collectors, history buffs, and even people who find the concept of a “100 quintillion” note fascinating. Common mid-range denominations may sell for just a few dollars, but top-tier notes in high grade can fetch significant sums. Their numismatic value has increased substantially over the years, and demand has kept prices on an upward trend, especially for professionally graded examples.

For enthusiasts looking to own a piece of Hungary’s currency collapse, there are many options. Planet Banknote features a range of graded pengő and adópengő banknotes from the hyperinflation period. Collectors can browse through PMG-certified pengő notes from modest billions to the staggering hundred-quintillion pengő notes. Each comes with a story contextualizing its place in the hyperinflation timeline. Holding one of these notes in hand can be awe-inspiring: the design and printing are of high quality, belying the chaotic economic conditions during which they were produced, and the strings of zeros serve as a sobering reminder of how money can lose meaning.

The Enduring Legacy

Ultimately, Hungarian hyperinflation banknotes have an enduring appeal to collectors because they encapsulate a singular moment in monetary history. They are conversation pieces, educational tools, and cautionary tales all in one. Whether one is interested in the 100 Million B.-Pengő note as the “largest banknote ever,” or an adópengő note as a quirky relic of a failed monetary experiment, these pieces carry lessons about economics and resilience. And unlike in 1946, when these notes could barely buy a loaf of bread, today they are treasured in a very different sense – as collectible pengő banknotes valued for their extraordinary historical legacy.
