The main purpose of this paper is to analyze problems of managing foreign exchange reserves in Taiwan since 1980. we have the following conclusions. 1.The motive for holding foreign exchange reserves in Taiwan is different from that in developed countries. In addition to transactionary, precautionary and speculative motives, there is another motive, which has been reflected in our foreign reserve managing policy: assisting economic development. 2.Currently, the Central Bank of China, CBC, is managing the foreign reserves of Taiwan in several ways: (1)Since 1972 the CBC has administered several different kinds of foreign capital financing operations for domestic and foreign borrowers. These are selective credit financing operations. They can also be regarded as a practical means of assisting economic developing. (2)The CBC has established foreign currency all loan market whose initial funds were provided by the foreign reserves. (3)Currently, the CBC has put some portion of the foreign reserves into foreign branches of domestic banks, and is aggressively participating in international financial cooperation. (4)As to foreign market operation the basic attitude of the CBC is to let the exchange rate be decided by market demand and supply. Only when market failure exists due to irrational phenomena or unexpected drastical fluctuation, will the CBC intervene.
