In fact, compared with the means he used in Weimar and China, schacht's strategy this time is much simpler. He founded a metallurgical research joint-stock company with a registered capital of only 6.5438 million marks (abbreviated as MEFO, so it is also abbreviated as MEFO). Specifically, the plan is as follows:
Pay the Mayfair bills issued by this shell company to the arms contractor, and then the contractor will find a German private bank to "discount" these bills, and the bank will be happy to give them cash because they know that the Bundesbank will definitely discount these Mayfair bills. Sources: gaimar, schacht, Mayford Draft and German Economic Revival 1933- 1939.
Because the Meffer draft never appeared in the official statement of the Bundesbank, people didn't know the size of the German army until Germany rearmed its troops and prepared for war.
This plan also includes many other aspects. If you are interested, you can have a good look at the articles mentioned above.
It is speculated that Hitler's hasty launch of World War II was mainly due to economic reasons: because a large number of Meifu bills were about to be discounted (usually it would take five years for Meifu bills to be discounted), and Germany did not have enough funds to cash them. The way they can get money is to invade and plunder other countries. In fact, schacht and Hitler had differences on the amount of funds needed for rearmament, and Hitler dismissed the governor of the central bank in 1939.
