Fresh from mauling the black market by threatening big players with bank freezes, the RBZ has struck another blow to Bureau De Changes. They are now supposed to pay not more than 7% above the trending interbank rate.
This gives the black market wind in its sails
This is likely to fuel trading on the black market as was happening before bureau de changes were liberalised. The restrictions on what people can buy means more buyers are going to look for foreign currency on the black market where they can freely trade.
It seems the central bank is more interested in styming the market than it is in solving the economic factors driving demand for foreign currency.
