Hyperinflation

Stabilising a Hyperinflation

How it ends

Eight steps, about twelve minutes, a question at each. You need no economics and no preparation, only a willingness to guess before you are told.

Step 1 of 8

The question

On 15 November 1923 a new German bank began issuing a currency worth 1 Billion Papiermark, which in English is a trillion.

The last part was what a hyperinflation takes away. This part is how each of these three stopped.

Why it matters and what it covers

All three did stop, within a few years of starting. The odd thing is how little the three endings have in common. They fall in 1923, 2009 and 2021, in three countries on three continents, and what did the work differs in each.

So the question these eight steps ask is whether Germany 1923, Zimbabwe 2009 and Venezuela 2021 have anything underneath them that is the same. The last step is where the comparison runs out.

What this module covers

  • What actually has to change for one of these to stop
  • The currency Germany brought in, and what stood behind it
  • What Germany's Reichsbank told the government that November
  • How Zimbabwe's ended
  • What that cost the country afterwards
  • How Venezuela's ended, and who decided it
  • The one thing all three had in common
  • How far each of them actually went

Written for every level. Tap any underlined word for what it means, and open the boxes below for the economics behind each decision. If you already know the theory, skip both and the history reads straight through.

Step 1 · Germany, Austria, Hungary, Poland

Four endings in the 1920s

Sargent's four European cases of the 1920s all ended the same way, as the government stopped needing its to pay for what it spent. The rule changes, not the month's decision.

The new money was being made because the was spending more than it raised. Close that gap and the reason to make the money closes with it.

Thomas Sargent studied what happened in Germany, Austria, Hungary and Poland in the 1920s, and named two essential measures each time. An independent central bank committed by law to refuse the government further unsecured credit. And a change to the tax and spending rules at the same moment.

The Peterson Institute's handbook opens its section on stopping them the same way: to stop one, a government must stop paying for its budget by making money.

central bank
The bank a government sets up to issue its money and set the interest rate the rest of the banking system builds on. It deals with banks and with the state rather than with the public.
Budget
The annual statement in which a government sets tax rates and spending plans for the year ahead and reports how the last year turned out. It is the main moment at which a government can change tax. Who delivers it differs by country: in Britain the Chancellor, in Germany the finance minister.

Take a guess. You are not expected to know the answers, and being wrong is what makes a number stick.

Three of these turn up in these episodes without ending one. Which is the odd one out?

Step 2 · 15 November 1923

Germany's Rentenmark arrives

On 15 November 1923 a new German bank began issuing the Rentenmark, and one Rentenmark was set equal to 1 Billion Papiermark.

The Papiermark was the old paper money, and the German word Billion is a million millions, a trillion in English. The new currency was a transitional one, replaced by the Reichsmark in August 1924.

The dollar was set at 4,20 Rentenmark, and that was fixed for all the exchanges on 20 November.

The German Reich lacked gold enough for the new bank's capital, so land was charged instead. The museum record calls it a mortgage of 3,2 Milliarden Rentenmark, which is 3.2 thousand million, a Milliarde being a thousand times smaller than a Billion. The federal archive calls the same act compulsory loans on farming land.

Getting people to hold the Rentenmark and getting the Reich to pay its bills were two jobs. The charge on the land is what the new notes were promised against, and what happened to the government's borrowing in the same weeks is what made them hold.

exchange rate
What one country's money is worth in another's. A stronger pound makes imports cheaper for people here and exports dearer for buyers abroad.

What was the Rentenmark issued against?

Step 3 · November 1923

What Germany's Reichsbank gave up

Germany's Reichsbank announced that it would stop discounting the government's Treasury bills from a cut-off date in November 1923.

A Treasury bill is a short-dated IOU from the German state. The bank bought them for less than they would pay out, and that gap is the discount the practice is named for. It paid with money it made, which is how the government's spending became the country's money.

The Bundesbank's own published history records the announcement, gives the cut-off as a date in November of that year, and says the bank kept to the deadline.

The new currency on its own would not have done it. Sargent's other three countries each wrote a limit on lending to the state into law, two of them by requiring security against every advance, the third by naming a maximum sum.

What did the Reichsbank announce it would stop doing?
