Finance Expert
M0, also known as the monetary base or narrow money, refers to the most liquid form of money supply in an economy. It includes: Currency in Circulation: Physical banknotes and coins held by the public.
M0 is the total amount of paper money and coins in circulation, plus the current amount of central bank reserves. M1 is the most frequently reported headline number. It is M0 plus money held in regular savings accounts and travelers' checks.
The money supply denoted by M0 is relatively straightforward. Reserve accounts of banks at the central bank would be M0, plus cash-in-circulation. By definition, M0 means central bank money (ie, a liability on the central bank balance sheet).
We'll start by looking at "base money" (M0), which refers to physical currency created by the central bank. Then, we'll move on to broader definitions, such as M1 (which includes currency in circulation plus checkable deposits) and M2 (which includes M1 plus savings accounts and other easily convertible assets).
Reserve Money (M0):
Reserve Money is also referred to as “High Powered Money” or the “Base Money.” It is the total liability of the RBI.

Narrow Money Explained
The term 'Narrow Money' is derived from the fact that M1/M0 are the narrowest or most restrictive types of money that form the basis for an economy's medium of exchange. The narrow supply of money includes only the most liquid financial assets. These funds must be available on-demand.
Money supply is measured and categorized on a scale from narrow to broad. Although the classification does vary depending on the country, it is typically classified through an “M” scale, where M0 includes the narrowest forms of the money supply, and M4 includes the broadest forms of the money supply.
The components of the most liquid measures of the money supply, M0 and M1, all act as a medium of exchange in the economy, while the added components of M2 are used primarily as a store of value. Thus, the general idea is that there is a positive relationship between the medium of exchange property and liquidity.
While money is finite, value (and therefore wealth) is not. Any time someone figures out a new use for something, that thing's value increases. Technological (not necessarily computer) advancements are constantly increasing the total amount of value in the world.
