The Marshall Plan aid was mostly used for the purchase of goods from the United States. The European nations had all but exhausted their foreign-exchange reserves during the war, and the Marshall Plan aid represented almost their sole means of importing goods from abroad. At the start of the plan, these imports were mainly much-needed staples such as food and fuel, but later the purchases turned towards reconstruction needs as was originally intended. In the latter years, under pressure from the United States Congress and with the outbreak of the Korean War, an increasing amount of the aid was spent on rebuilding the militaries of Western Europe. Of the some $13 billion allotted by mid-1951, $3.4 billion had been spent on imports of raw materials and semi-manufactured products; $3.2 billion on food, feed, and fertilizer; $1.9 billion on machines, vehicles, and equipment; and $1.6 billion on fuel.Also established were counterpart funds, which used Marshall Plan aid to establish funds in the local currency. According to ECA rules, recipients had to invest 60% of these funds in industry. This was prominent in Germany, where these government-administered funds played a crucial role in lending money to private enterprises which would spend the money rebuilding. These funds played a central role in the reindustrialization of Germany. In 1949–50, for instance, 40% of the investment in the German coal industry was by these funds.The companies were obligated to repay the loans to the government, and the money would then be lent out to another group of businesses. This process has continued to this day in the guise of the state-owned KfW bank, (Kreditanstalt für Wiederaufbau, meaning Reconstruction Credit Institute). The Special Fund, then supervised by the Federal Economics Ministry, was worth over DM 10 billion in 1971. In 1997 it was worth DM 23 billion. Through the revolving loan system, the Fund had by the end of 1995 made low-interest loans to German citizens amounting to around DM 140 billion. The other 40% of the counterpart funds were used to pay down the debt, stabilize the currency, or invest in non-industrial projects. France made the most extensive use of counterpart funds, using them to reduce the budget deficit. In France, and most other countries, the counterpart fund money was absorbed into general government revenues, and not recycled as in Germany.The Netherlands received US aid for economic recovery in the Netherlands Indies. However, in January 1949, the American government suspended this aid in response to the Dutch efforts to restore colonial rule in Indonesia during the Indonesian National Revolution, and it implicitly threatened to suspend Marshall aid to the Netherlands if the Dutch government continued to oppose the independence of Indonesia.At the time the United States was a significant oil producing nation — one of the goals of the Marshall Plan was for Europe to use oil in place of coal, but the Europeans wanted to buy crude oil and use the Marshall Plan funds to build refineries instead. However, when independent American oil companies complained, the ECA denied funds for European refinery construction.
