Few images capture a financial crisis like Germans pushing wheelbarrows of banknotes to buy bread, or children playing with bundles of worthless money. In 1923, the German mark collapsed in one of history's most famous hyperinflations. In Part 5 of Great Financial Crises, we look at what caused it, what life was like and how it was finally stopped.
What is hyperinflation?
Inflation is a general rise in prices. Hyperinflation is an extreme form, often defined as prices rising by 50% or more in a single month. At that pace, money loses value so quickly that people try to spend it the moment they receive it.
The roots: war and debt
Germany financed much of World War I by borrowing and printing money rather than raising taxes, expecting to win and make the losers pay. By the end of the war in 1918, prices had already risen significantly, and the mark had lost much of its value.
Defeat brought the Treaty of Versailles, which required Germany to pay large reparations to the Allies. The amount was set in 1921 and had to be paid largely in gold or foreign currency. Economists still debate how much reparations themselves caused the hyperinflation, but they added huge pressure to an already fragile budget.
Printing money to cover the gap
The new Weimar Republic faced war debts, pensions, unemployment and reparations, with weak tax revenues and political instability. The government increasingly covered deficits by having the central bank, the Reichsbank, discount government debt, effectively printing money. Inflation accelerated through 1922.
The Ruhr crisis of 1923
In January 1923, after Germany fell behind on reparations deliveries, French and Belgian troops occupied the Ruhr, Germany's industrial heartland. The German government urged workers to resist passively by going on strike and paid them to do so.
The Ruhr economy ground to a halt, tax revenues fell further and spending rose. The government printed money on a massive scale to cover the gap, using hundreds of printing presses. Inflation exploded into hyperinflation.
Life in hyperinflation
- Prices rose so fast that workers were paid daily, sometimes twice a day, and rushed to spend wages before they lost value.
- Banknotes were issued in ever-larger denominations, eventually reaching 100 trillion marks.
- People traded goods directly, and foreign currencies such as the dollar became highly sought after.
- Savers and people on fixed incomes, such as pensioners, saw their savings wiped out. Debtors, including those with mortgages, effectively had their debts erased.
- Some people who owned real assets, such as land, factories or foreign currency, became richer, deepening resentment.
By November 1923, one US dollar was worth about 4.2 trillion paper marks.
How it was stopped
In autumn 1923, a new government under Chancellor Gustav Stresemann ended passive resistance in the Ruhr. Finance Minister Hans Luther designed a stabilisation plan, and Hjalmar Schacht was appointed currency commissioner.
On 15 November 1923, a new currency, the Rentenmark, was introduced. With no gold available, it was backed by a mortgage on agricultural and industrial land. Its value was fixed at 1 Rentenmark for 1 trillion paper marks, which kept the dollar at about 4.2 Rentenmarks.
Crucially, the government strictly limited how many Rentenmarks could be issued and stopped financing deficits by printing money. Luther cut spending and balanced the budget by early 1924. Confidence returned remarkably quickly, and prices stabilised.
In 1924, the Dawes Plan restructured reparations payments and brought foreign loans. In August 1924, the gold-backed Reichsmark was introduced at the same value as the Rentenmark.
Long-term consequences
The hyperinflation destroyed the savings of much of Germany's middle class and undermined trust in the Weimar Republic. Historians often link these experiences, along with the Great Depression a few years later, to the political extremism that followed. The memory of 1923 also shaped Germany's strong commitment to price stability and an independent central bank after World War II.
Other hyperinflations
Germany's was not the worst. Hungary in 1946 experienced the highest recorded hyperinflation, and Zimbabwe (2007 to 2009) and Venezuela in the late 2010s also suffered extreme inflation. Common causes include war or economic collapse, large deficits financed by money creation, and a loss of confidence in the currency.
Lessons for investors today
- Cash is not always safe. In high inflation, money held as cash or fixed-income savings loses value quickly.
- Real assets and diversification help protect wealth against inflation.
- Central bank independence matters. When governments can freely print money to fund spending, currencies can collapse.
- Confidence can be restored with credible fiscal and monetary discipline, as the Rentenmark showed.
In Part 6, we look at the 1970s, when oil price shocks brought high inflation and economic stagnation together.
