During the 1980s, significant opposition to apartheid grew in the USA, particularly as the fear from the USSR and communism diminished. Congress overrode the president’s veto over sanctions → more companies withdrew investment. US banks (Chase Manhattan) began to refuse to renew loans, for example $10 million of short-term loans maturing in 1987, creating a severe financial crisis which led in part to the South African government beginning negotiations to end apartheid.
