FIELD LISTING :: STOCK OF NARROW MONEY
This entry, also known as "M1," comprises the total quantity of currency in circulation (notes and coins) plus demand deposits denominated in the national currency held by nonbank financial institutions, state and local governments, nonfinancial public enterprises, and the private sector of the economy, measured at a specific point in time. National currency units have been converted to US dollars at the closing exchange rate for the date of the information. Because of exchange rate movements, changes in money stocks measured in national currency units may vary significantly from those shown in US dollars, and caution is urged when making comparisons over time in US dollars. Narrow money consists of more liquid assets than broad money and the assets generally function as a "medium of exchange" for an economy.

note: Zimbabwe's central bank no longer publishes data on monetary aggregates, except for bank deposits, which amounted to $2.1 billion in November 2010; the Zimbabwe dollar stopped circulating in early 2009; since then, the US dollar and South African rand have been the most frequently used currencies; there are no reliable estimates of the amount of foreign currency circulating in Zimbabwe
