The dollars—and pounds, and francs—came pouring in. Speculators and small savers across Western Europe raced to exchange their currencies for the Deutsche Mark. “Hot money” flowed into Germany at astounding rates. The reserves of West Germany's central bank, the Bundesbank, shot up by DM 9.4 billion ($2.15 billion) in the first three weeks of November 1968—with DM 7.3 billion arriving in just three days of trading. Airports in Germany barred exchanges of more than one hundred francs at a time; train stations in Zurich stopped accepting French notes altogether.
