The koruna (Kčs), or crown, was the national currency and consisted of 100 haléřů. In 1986 the currency continued to be convertible only under restricted conditions and at official rates. Violation of exchange regulations constituted a serious offense. The koruna could be used only within the country and was not used in foreign trade. In 1987 the official, or commercial, exchange rate was Kcs5.4 per US$l; the tourist, or noncommercial, rate was Kcs10.5 per US$l. The koruna was legally defined in terms of 123 milligrams of gold, which provided a historical basis for the commercial rate.The main function of the banking system was to act as the government's agent in implementing the financial plan, an important part of which consisted of expanding and contracting credit to meet the economy's needs. The central authorities controlled most investments directly, and the national plan regulated production. The State Bank acted as a supervisory agent in extending credit to the enterprises, ensuring that the investments met plan goals. The bulk of bank credit was for working capital, largely utilized to finance the purchase of materials and the sale of finished products. The powers of the State Bank appeared to be somewhat limited, however, since credit was extended according to guidelines for planned production.
