Any mention of money printing in Zimbabwe fuels fears of a return to hyper inflation and the black market trade in scarce foreign currency that peaked in 2008.
Bond notes were introduced last November to ease chronic shortages of US dollars, and to encourage exporters who earn the country foreign currency.
'Drip feed basis'
The central bank has so far fed 175 million dollars’ worth of the notes, in denominations of two and five dollars, into the economy.
But in a monetary policy statement on Wednesday, Central Bank Chief John Mangudya said another 300 million dollars of the notes would be released, backed, like the first 200 million, by a loan from the Cairo-based African Export-Import Bank (Afreximbank).
"As like under the 200 million US-dollar facility, the (central) bank will release the bond notes into the market on a drip-feed basis," he said.
