The grey economy is the real one In an economy in which 8 out of 10 people are unemployed, the only job Sifiso Nyoni, 26, has ever had is as a currency trader, but she has no idea who she really works for.
"Every foreign currency dealer on the street knows that the people who bring the money to us [and communicate the rates] are just small," she said. "But there are others - bigger people, who are controlling the black market."
Despite numerous measures put in place by the Reserve Bank of Zimbabwe to try and curb the parallel currency market, it continues to thrive, mainly because it offers much better prices than the official rate, and - so the rumour goes - because the cash-strapped government itself uses it.
"The rates are attractive on the black market, so I will rather risk arrest than change at the banks, where the rates are ridiculously low," said Mercy Sibanda, who had just changed R100 (around US$10).
Currently the US dollar is trading at Z$100,000 and the South African rand is worth Z$10,000. At independence in 1980, one Zimbabwean dollar fetched US$1.47.
