Poland 1923: The Marka Hyperinflation and the Birth of the Zloty
Poland's hyperinflation ran from January 1923 to January 1924 and peaked in October 1923, when wholesale prices rose 275 percent in a single month and doubled roughly every 16 days (Hanke-Krus World Hyperinflation Table, Cato Institute). The largest banknote Poland ever put into circulation was the 10,000,000 marka note dated 20 November 1923, cataloged as Pick 39 (Standard Catalog of World Paper Money), and the crisis ended when Wladyslaw Grabski's reform replaced the marka with the zloty at 1,800,000 to 1 in late April 1924.

Poland's marka hyperinflation lasted thirteen months, from January 1923 to January 1924, and reached a peak monthly inflation rate of 275 percent in October 1923, an equivalent daily rate of 4.50 percent, with prices doubling every 16.0 days (Hanke-Krus World Hyperinflation Table, Cato Institute). That places Poland seventeenth on the Hanke-Krus ranking of documented hyperinflations, severe by any standard, yet roughly two orders of magnitude milder than the German episode raging across the border at exactly the same moment. Poland's story is the quieter twin of Weimar, and in some ways the more instructive one. A brand new state, stitched together in 1918 from three separate imperial currency zones, fought a war with Soviet Russia, rebuilt a shattered countryside, and paid for all of it on the printing press. The banknotes tell the arc precisely: the Polish National Loan Fund went from a 10,000 marka top denomination in March 1922 to 10,000,000 marka in November 1923, a thousandfold jump in twenty months.
Why did the Polish marka collapse?
The marka collapsed because the Second Polish Republic had to finance national reconstruction, a war with Soviet Russia, and the unification of three separate imperial economies before it had a functioning tax system, and it covered the gap by issuing notes. Currency in circulation grew from 880 million marka at the 1918 Armistice to 207 billion marka by 1922, and then accelerated (Polish marka, Wikipedia).
The currency itself was an inheritance rather than a choice. The marka polska was created by decree on 9 December 1916 under German occupation, issued by the Polska Krajowa Kasa Pozyczkowa, the Polish National Loan Fund, and deliberately pegged in name and design to the German mark. When Poland regained independence in November 1918, this occupation currency was the only monetary infrastructure that existed. A law of 15 January 1920 made the marka legal tender across the entire Republic, absorbing the Russian rubles of the former Congress Kingdom, the Austrian crowns of Galicia, and the German marks of the Prussian partition into a single unit.
What followed was a textbook fiscal deficit spiral. The Polish-Soviet War of 1919 to 1921 consumed resources the new treasury did not have, reconstruction of a countryside fought over for four years consumed more, and tax collection machinery had to be built from nothing in territories that had never been administered as one country. The Loan Fund covered the shortfall by advancing notes to the government, and each new issue reduced the value of the last.
By early 1923 the process had crossed into self-sustaining territory. Wages chased prices, prices chased the exchange rate, and the exchange rate chased the presses. The timing was brutal: France and Belgium occupied the Ruhr in January 1923, and the German papiermark went into freefall alongside the marka, so Poland's largest trading partner and its currency benchmark were disintegrating simultaneously. For that side of the story see the Weimar hyperinflation of 1922 to 1923, and for where both episodes sit against the full record see every hyperinflation ranked.
How bad was it compared with Germany and Austria?
Poland's peak was 275 percent per month in October 1923. Germany's peak, in the very same month, was 29,500 percent per month, more than a hundred times faster. Austria's earlier episode peaked at 129 percent in August 1922, and the Free City of Danzig, which used the German papiermark, peaked at 2,440 percent in September 1923 (all figures: Hanke-Krus World Hyperinflation Table, Cato Institute).
| Country | Currency | Episode | Peak month | Peak monthly rate | Daily rate | Prices double in |
|---|---|---|---|---|---|---|
| Germany | Papiermark | Aug 1922 to Dec 1923 | Oct 1923 | 29,500% | 20.9% | 3.70 days |
| Free City of Danzig | German papiermark | Aug 1922 to mid-Oct 1923 | Sep 1923 | 2,440% | 11.4% | 6.52 days |
| Poland | Marka | Jan 1923 to Jan 1924 | Oct 1923 | 275% | 4.50% | 16.0 days |
| Austria | Crown | Oct 1921 to Sep 1922 | Aug 1922 | 129% | 2.80% | 25.5 days |
Those numbers deserve a moment. A doubling time of 16 days sounds almost manageable next to Germany's 3.7 days, but compounded over a year it is catastrophic. Polish wholesale prices rose 4,303 times between December 1921 and March 1924 (HISTORIA.org.pl). A savings account opened in late 1921 and left untouched through the reform retained a tiny fraction of the purchasing power it started with, and fixed incomes, pensions, insurance policies, and long-term contracts were all rewritten by arithmetic.
Poland's episode also stands out for how it ended. Austria's crown was rescued under the League of Nations reconstruction scheme agreed in the Geneva Protocols of October 1922, while Poland stopped its own hyperinflation through domestic legislation and a new issuing bank. The dating shows it worked: the Hanke-Krus end date is January 1924, three months before the new currency reached the public.
For the far end of the scale, the Polish figures are dwarfed by the Hungarian pengo of 1946, which holds the record at 4.19 x 1016 percent per month with prices doubling every 15 hours (Hanke-Krus World Hyperinflation Table, Cato Institute). See Hungary 1945 to 1946 and Yugoslavia 1992 to 1994.
What were the largest Polish marka banknotes?
The largest Polish banknote ever released for general circulation was the 10,000,000 marka note dated 20 November 1923, cataloged as Pick 39 (Standard Catalog of World Paper Money; issue dates from the Polish National Loan Fund banknote record). The top denomination climbed from 10,000 marka in March 1922 to 10,000,000 marka in November 1923, a thousandfold increase in twenty months, and the whole family of inflation-era notes was issued across five printed dates.
| Denomination | Printed date | Pick number | Note |
|---|---|---|---|
| 10,000 marka | 11 March 1922 | P-32 | First of the inflation issues |
| 50,000 marka | 10 October 1922 | P-33 | |
| 250,000 marka | 25 April 1923 | P-35 | Issued ahead of the 100,000 |
| 100,000 marka | 30 August 1923 | P-34 | |
| 500,000 marka | 30 August 1923 | P-36 | |
| 1,000,000 marka | 30 August 1923 | P-37 | First seven-figure Polish note |
| 5,000,000 marka | 20 November 1923 | P-38 | |
| 10,000,000 marka | 20 November 1923 | P-39 | Highest circulating banknote denomination |
The sequencing in that table is one of the small oddities collectors enjoy. The 250,000 marka note carries an earlier printed date, 25 April 1923, than the 100,000 marka note dated 30 August 1923, which is why the Pick numbers run out of numerical order against the dates. Catalog numbering follows denomination order rather than chronology. If Pick numbers are new to you, our guide to Pick catalog numbers explains how the system is built and why anomalies like this one appear.
Above the banknotes sat something rarer. Alongside the million-marka notes, the Polish National Loan Fund printed bearer transfer orders, known as przekazy, in denominations of 50,000,000 and 100,000,000 marka, carrying the same date of 20 November 1923. They were not banknotes. Each carried a promise to pay the bearer up to 31 March 1924, the reverse was left blank, and they served as paper money in the final months before the zloty (Przekazy Polskiej Krajowej Kasy Pozyczkowej, Wikipedia). A 50,000,000 marka banknote was being prepared for early 1924, but the Grabski reform overtook it before issue (Banknoty Polskiej Krajowej Kasy Pozyczkowej 1919 to 1923, Wikipedia). That makes 10,000,000 marka the ceiling of Polish circulating banknotes, and it is a useful benchmark: Poland never approached the scale reached by the German 100 trillion mark note, and it never needed to.
All Polish National Loan Fund notes issued from early 1919 onward were withdrawn from circulation on 1 July 1924, once the zloty was established. Anything that survives today survived because somebody kept it deliberately.
What did the collapse look like in daily life?
In Lublin, a kilogram of lard cost 151,000 marka in October 1923 and 268,000 marka a month later. Beef went from 77,000 to 110,000 marka per kilogram over the same four weeks (HISTORIA.org.pl). Those are the prices a household actually faced while the top banknote in the country was still only 1,000,000 marka.
That gap between wallet capacity and shopping-basket cost is the defining physical experience of hyperinflation. When the largest note is 1,000,000 marka and a kilogram of lard costs 268,000, an ordinary week of groceries requires a bundle rather than a bill. The Loan Fund's answer, issuing 5,000,000 and 10,000,000 marka notes on 20 November 1923, arrived within weeks of those Lublin prices being recorded.
| Year | Marka per US dollar |
|---|---|
| 1918 | 9 |
| 1919 | 110 |
| 1920 | 590 |
| 1921 | 2,922 |
| 1922 | 17,800 |
| 1923 | 6,375,000 |
| 1924 | 9,250,000 |
Read down that column and the shape of the crisis is obvious. Between 1918 and 1922 the marka lost ground steadily but comprehensibly, roughly a factor of two thousand across four years. Then 1922 to 1923 alone multiplies the dollar price by more than 350 times. That is the moment inflation became hyperinflation. Independent point readings record roughly 5,000,000 marka per dollar in November 1923 and about 9,300,000 in January 1924 (Polish marka, Wikipedia), corroborating the trajectory.
The human consequences ran along familiar lines. Anyone holding cash or a fixed claim lost ground weekly, anyone holding land, goods, or foreign currency did comparatively well, and wage negotiations moved from annual to monthly to weekly. It is the same pattern seen in every episode we document, from Weimar Germany to modern Venezuela.
How did the Grabski reform end the crisis in 1924?
Wladyslaw Grabski became Prime Minister on 19 December 1923 while simultaneously holding the Treasury portfolio, and the Sejm passed the Act of 11 January 1924 on the repair of the State Treasury and currency reform (Wladyslaw Grabski, Wikipedia). That act created a new monetary system and a new issuing bank, and at the end of April 1924 the Bank of Poland began issuing the zloty at a rate of 1,800,000 marka to 1 zloty (Polish zloty, Wikipedia).
The design of the reform mattered as much as the arithmetic. Grabski liquidated the Polish National Loan Fund, the wartime institution that had been advancing notes to the government since 1916, and replaced it with Bank Polski SA, structured as a joint stock company precisely so that it would sit at arm's length from the treasury. Shares were sold to private subscribers during the winter of 1924, and the first shareholders' meeting on 15 April 1924 completed the formal establishment (Wladyslaw Grabski, Wikipedia). Cutting the physical link between the government's spending needs and the note press was the whole point.
The new zloty was defined against gold at 9/31 of a gram of pure gold, roughly 0.2903 grams, which put it at par with the Swiss franc and set the dollar rate at 5.18 zloty (The Mark, the Lech and the Zloty, Polish History). Deliberately choosing parity with a respected European currency was a credibility signal aimed as much at Polish savers as at foreign markets.
The name carries its own story. In 1919 a decree proposed calling the future currency the "lech," after the legendary founder of the Polish nation, but within three weeks the name was changed to "zloty," which simply means "golden" and reaches back to Poland's pre-partition coinage (The Mark, the Lech and the Zloty, Polish History). The first zloty banknotes carry the printed date 28 February 1919 even though they did not reach the public until 1924, a five-year gap between the paper's stated date and its actual release (Polish zloty, Wikipedia).
The old notes were withdrawn on 1 July 1924, and the marka ceased to circulate. Poland's hyperinflation had already been arrested by January 1924 according to the Hanke-Krus dating, which means the announcement and legislation did most of the work before a single zloty note was printed. That is the same lesson visible in the Hungarian pengo to forint conversion of 1946: hyperinflations end when the fiscal source is credibly closed, not when new paper appears.
What should collectors know about 1923 marka notes?
The 1923 Polish marka issues are among the most accessible entry points into serious hyperinflation collecting, because the full arc from 10,000 to 10,000,000 marka is contained in eight catalog numbers issued across five printed dates. A run of P-32 through P-39 tells the entire story on a single page of an album.
Design is the first thing people notice. The Polish National Loan Fund banknote record describes the inflation denominations as graphically a complete break from the earlier so-called Viennese series (Banknoty Polskiej Krajowej Kasy Pozyczkowej 1919 to 1923, Wikipedia), and side by side the two families barely look like the same country's money. Seeing that shift laid out in order is one of the reasons we assemble multi-country hyperinflation sets.
On condition, the usual hyperinflation logic applies. Notes issued late in an episode often circulated for only weeks before demonetization, so uncirculated examples of the very largest denominations can be more available than well-preserved examples of the everyday small notes that were handled to death. Before you buy, read our banknote grading guide so that terms like VF, AU, and Gem UNC mean something concrete, and our comparison of graded versus raw banknotes if you are weighing third-party certification.
Two practical cautions. Novelty reproductions of famous hyperinflation notes circulate widely online, and although they are usually marked, the markings are easy to miss in a photograph; our guide to spotting counterfeit and reproduction banknotes covers the paper, ink, and watermark checks that settle it. And century-old paper is fragile in exactly the ways you would expect, so see how to store banknotes for archival sleeve and humidity guidance.
Availability shifts constantly and prices vary with grade, centering, and inventory. Current stock lives on our hyperinflation sets category, certified material under graded banknotes. If you are just starting, how to collect world banknotes is the right first read.
Frequently asked questions
How bad was Poland's hyperinflation in 1923?
Poland's hyperinflation ran from January 1923 to January 1924 and peaked in October 1923 at 275 percent per month, equivalent to 4.50 percent per day, with prices doubling every 16.0 days (Hanke-Krus World Hyperinflation Table, Cato Institute). Polish wholesale prices rose 4,303 times between December 1921 and March 1924 (HISTORIA.org.pl). That ranks Poland seventeenth among documented hyperinflations, severe but far milder than neighboring Germany's simultaneous collapse.
What was the highest Polish marka banknote ever issued?
The highest circulating Polish banknote was the 10,000,000 marka note dated 20 November 1923, cataloged as Pick 39 (Standard Catalog of World Paper Money; issue dates from the Polish National Loan Fund banknote record). It was issued alongside a 5,000,000 marka note of the same date. The Polish National Loan Fund also printed bearer transfer orders, called przekazy, of 50,000,000 and 100,000,000 marka carrying the same date, payable to the bearer up to 31 March 1924, but those were not banknotes (Przekazy Polskiej Krajowej Kasy Pozyczkowej, Wikipedia).
What was the Grabski reform?
The Grabski reform was Poland's 1924 currency and fiscal stabilization, led by Wladyslaw Grabski, who became Prime Minister on 19 December 1923 while also serving as Treasury Minister. The Act of 11 January 1924 created a new monetary system, liquidated the Polish National Loan Fund, and established Bank Polski SA as an independent joint stock issuing bank (Wladyslaw Grabski, Wikipedia). The zloty entered circulation at the end of April 1924.
How many marka were exchanged for one zloty?
The conversion rate was 1,800,000 Polish marka to 1 zloty (Polish zloty, Wikipedia). The new zloty was defined at 9/31 of a gram of pure gold, approximately 0.2903 grams, which placed it at par with the Swiss franc and set the exchange rate at 5.18 zloty to one US dollar (The Mark, the Lech and the Zloty, Polish History). All Polish National Loan Fund notes issued from early 1919 onward were withdrawn from circulation on 1 July 1924.
Are 1923 Polish marka banknotes hard to find today?
The eight inflation-era denominations from 10,000 to 10,000,000 marka remain obtainable, though availability in any given grade shifts constantly. Notes issued late in the crisis circulated only briefly before the July 1924 withdrawal, so high-grade examples of the largest denominations often surface more readily than crisp examples of heavily handled smaller notes. Prices vary with grade and inventory; see our Poland banknotes category for current stock.
