Most Germans Wanted Hard Money Because a Single Generation Had Lost Its Monetary Savings Twice: In the Hyperinflation of 1923 and in the Currency Reform of 1948

The EMS [European Monetary System] tried to fix exchange rates that had been allowed to float in a corridor of ±2.25 percent around the official rate. But the intention of fixed exchange rates was incompatible with the system built to achieve that aim. The idea was that when the exchange rate would threaten to leave the corridor, central banks would intervene to bring the rate back into the corridor. For this to happen, a central bank would have to sell its currency, or in other words, produce more money when the currency was appreciating and moving above the corridor. It would have to buy its currency, selling assets such as foreign exchange reserves, if its currency was depreciating, falling below the corridor.

The Spanish Central Bank provides us with a good example. If the peseta appreciated too much in relation to the Deutschmark, the Bank of Spain had to inflate and produce pesetas to bring the peseta's price down. The central bank was probably very happy to do so. As it could produce pesetas without limits, nothing could stop the Bank of Spain from preventing an appreciation of the peseta. However, if the peseta depreciated against the Deutschmark, the Bank of Spain would have to buy its currency and sell its Deutschmark reserves or other assets, thereby propping up the exchange rate. This could not be done without limits, but was strictly limited to the reserves of the Bank of Spain. This was the basic misconstruction of the EMS and the reason it could not work. It was not possible to force another central bank to cooperate, i.e., to force the Bundesbank to buy peseta with newly produced Deutschmarks when the peseta was depreciating. In fact, the absence of such an obligation was a result of the resistance of the Bundesbank. France called for a course of required action that would reduce the independence of the Bundesbank. Bundesbank president Otmar Emminger resisted being obliged to intervene on part of falling currencies in the EMS. He finally got his way and the permission from Helmut Schmidt to suspend interventions leading to the purchase of foreign currencies within the EMS agreements. Countries with falling currencies had to support their currencies themselves.

Indeed, an obligation to intervene in favor of falling currencies would have created perverse incentives. A central bank that inflated rapidly would have forced others to follow. Fiat paper currencies are introduced for redistribution within a country. Fixed fiat exchange rates coupled with an obligation to intervene allowed for redistribution between countries. In such a setup, the faster inflating central bank (Bank of Spain) would force another central bank (Bundesbank) to follow and buy up faster, inflating one’s currency. The Bank of Spain could produce pesetas that would be exchanged into Deutschmarks buying German goods. Later the Bundesbank would have to produce Deutschmarks to buy peseta and stabilize the exchange rate. There would be a redistribution from the slower-inflating central bank to the faster-inflating central bank.

Yet, in the EMS there was no obligation to buy the faster-inflating currency. This implied also that the EMS could not fulfil its purpose of guaranteeing stable exchange rates. Fixed fiat exchange rates are impossible to guarantee when participating central banks are independent. Governments wanted both fiat money production for redistributive internal reasons and stable exchange rates. This desire makes voluntary cooperation in the pace of inflation necessary. Without voluntary cooperation, coordinated inflation is impossible. The Bundesbank was usually the spoilsport of coordinated inflation. It did not inflate fast enough when other central banks, such as the Bank of Italy, inflated the money supply to finance Italian public deficits.

The Bundesbank did not inflate as much on account of German monetary history. A single generation had lost almost all monetary savings two times, namely, after two world wars: in the hyperinflation of 1923 and the currency reform in 1948. Most Germans wanted hard money, and expressed that through the institutional set up of the Bundesbank, which was relatively independent of the government. What all of this means is that, in practice, the EMS would only function if central banks were only able to inflate as much as the slowest links in the chain: the Bundesbank and its traditional ally, De Nederlandsche Bank.
