Zimbabwe's finance minister Patrick Chinamasa says that he knows the new bond notes aren't meeting the country's demand for cash. Chinamasa told Parliament that Zimbabweans' needs for cash will be met in due course.The central bank injected 10 million bond notes and two million bond coins into the system on Monday -- to local and international criticism. Advertised as a bid to stimulate exports, bond notes are a surrogate currency, similar to Zimbabwe's bearer cheques between 2003 and 2009. Overprinting back then sparked hyperinflation and widespread shortages. But the central bank insists that won't happen again.
