The mechanism of inflation was simple. The government issued paper promises to pay, and the Reichsbank issued money on the security of these promises. When a government spends more than its income, it must borrow. If it merely borrows money from its citizens by selling them bonds, there need be no inflation. Instead of that money being spent or invested by the citizen, it is borrowed and spent by the government, but the total amount of money is not increased.
When the government needs more money than its people are able or willing to lend it, it monetizes the debt. That is what happens in this country when the government runs a big deficit. The Federal Reserve (our central bank) "buys" as many bonds as necessary to stabilize the market. It prints money on the security of these bonds. Despite the facade of the government supposedly "borrowing," the net result is the creation of printing press money. (Actually these days the money is created in the form of new bank deposits--checkbook money--but the net result is exactly the same as if bills were printed.)
This is what happened in Germany. The government issued notes which were promptly discounted by the Reichsbank, i.e., the bank issued money on the "security" of these worthless notes. To compound the evil, the bank failed to raise its interest rate sufficiently. Businessmen found it very profitable to borrow money from the bank and buy up goods, shares and companies. Their debt was wiped out within weeks by the rapid inflation, and the businessman remained holding the valuable assets he had bought. The net result was a huge "private inflation" caused by the rapid expansion of credit. Even foreign exchange was bought with borrowed money, so that the Reichsbank actually financed speculation against its own currency. Yet the bank refused to raise interest rates, arguing that this would only add to the cost of business and thus would increase inflation!
The tax system virtually broke down. Businessmen found that by merely delaying tax payments, the depreciation in the mark would virtually eliminate their true value. But the government, lacking adequate income, felt forced to resort more and more to creating money. By October 1923, 1% of government income came from taxes and 99% from the creation of new money.
