VIII. Trade and Project Financing There are five commercial banks operating in Botswana: Barclays Bank of Botswana, First National Bank, Standard Chartered Bank, Union Bank, and Zimbank. The Bank of Botswana was established in 1975 and is responsible for management of Botswana's substantial foreign exchange reserves. The Bank of Botswana also administers exchange controls and regulates financial institutions operating in Botswana. Short-term finance, including pre-and post-shipment credit, is readily available through the commercial banking system at market rates of interest. Export credit insurance is available through local insurance companies. The credit environment in Botswana is more favorable to investors than in most of sub-Saharan Africa. Provisions for U.S. and other foreign firms borrowing in Botswana are liberal, local banks are highly liquid, and interest rates are presently negative in real terms. However, Botswana's commercial banks have been hampered from making long-term credit available by the short maturity nature of their deposits, and their small capital base. At present, commercial banks finance only about USD 18.5 million of the total USD 55.5 million invested each year in industrial development projects. A Government parastatal, the Botswana Development Corporation (BDC), contributes a similar amount, leaving two-thirds of the total capital invested in industrial development to come from private sector funds, reinvested profits, and foreign capital. The availability of foreign aid and Botswana's favorable balance of payments situation has meant the country -- with one or two exceptions -- has not been forced to borrow externally on commercial terms. The World Bank and the African Development Bank have, however, provided several long-term loans to the government and various parastatals, often at near commercial rates. These loans have typically been for financing major infrastructure projects. Total public external debt increased from USD 155.6 million to USD 565.5 million during 1980 - 1990, and the debt service ratio increased from 1.9 percent to 5.3 percent. Eximbank programs are available to exporters to finance exports to Botswana. Eximbank has not, however, been active in Botswana in recent years. All five commercial banks operating in Botswana have correspondent relationships with U.S. banks.
