7. not according to the man who stabilized the mark.
"The dollar reached an exchange rate of 12 trillion marks on the free market of the Cologne Bourse. This speculation was not only hostile to the country's economic interests, it was also stupid. In previous years such speculation had been carried on either with loans which the Reichsbank granted lavishly, or with emergency money which one printed oneself, and then exchanged for Reichsmarks.
Now however, three things had happened. The emergency money had lost its value. It was no longer possible to exchange it for Reichsmarks. The loans formerly easily obtained from the Reichsbank were no longer granted, and the Rentenmark could not be used abroad. For these reasons the speculators were unable to pay for the dollars they had bought when payment became due (and they) made considerable losses."
Hjalmar Schact, Stabilizing the Mark
According to schact, it was not the printing of money, it was the speculative attacks on the mark (i.e. short-selling).
The german hyperinflation began in 1922 a few months after the german central bank was made independent of control by the government -- i.e. run entirely by private bankers. (The autonomy law).
The german hyperinflation ended in 1923 when hjalmar schacht instituted regulations that made the speculation that had been going on much more difficult.
