When did recipients of aid have to pay for the war goods?
a.) never
b.)at some point
c.)when war broke out
d.)when the war ended

The correct option is B

The OECE had taken over the distribution of the funds and the ACE was in charge of European imports. US producers were paid in dollars from the Marshall Plan and the imported goods, of course, were not free, but Europeans had to pay for them, either cash or credit, with the local currency. This money was going to a counter value fund, and could be reused for investment projects.

Most of the countries participating in the Plan already knew from the beginning that they would never have to return the money deposited in the countervalue funds to the United States, so they were absorbed into national budgets and "disappeared". On the contrary, all the aid offered to Germany had to be returned; although after the agreements of London on the debts of 1953, the amount to return was reduced to 1 000 million dollars (including the war reparations). The aid given to the Germans until July 1, 1951 amounted to 270 million dollars, of which the Germans returned 16.9 through the Export-Import Bank of the United States. In fact, until 1953, Germany did not know the exact amount of money to be returned to the United States, and insisted that money from the countervalue funds was given only in the form of loans, a system through which, thanks to the interests, money grew instead of being reduced. The United States commissioned a mortgage bank to be in charge of controlling the system, and loans from the European Recovery Program were mostly used to support the activity of small and medium-sized enterprises. In the end, Germany paid the debt in installments, payment that ended in June 1971. However, the money for the payment of the debt came out of the national budgets, and not from the counter value funds, so these today continue existing.
