First, the large scale speculation on the free floating exchange rate of currencies has been a relatively new trading enterprise, starting more or less in 1971 after the breakup of the Bretton Woods monetary system that had pegged (“fixed”) major currencies to the US Dollar (which was itself supposedly convertible to gold). In August 1971, Nixon terminated the convertibility to gold, which ended the fixed, “gold backed” system’s 26 year life (1945-1971), and allowed currencies once more to be free floating and only paper based (fiat). The New York Stock Exchange (NYSE) in contrast has been around since May 17, 1792, which gives it a 179+ year head start.

Isikhala esihlukanise imigqa kwisivini ngokujwayelekile sisuka phakathi kka 2.1m kuya ku 3.0m kodwa siba umngcingo ukwenzela ukusebezinsa kahle umhlabathi ngokwanele. Ngakhoke lokhu kukhuphula izinga lomkhiqizo nge hekhithari umphumela walokho ukuzuza inani eliphezulu nge hekhithari.
