The measure is equivalent to the US M3 (see Money supply for US definitions).
M4 = M0 + UK residents' bank deposits + deposits made by the private sector
Where M0 (Narrow Money) denotes the total of notes and coin in circulation in the economy plus commercial banks' deposits with the Bank of England.
There are several different definitions of money supply to reflect the differing stores of money. Due to the nature of bank deposits, especially time-restricted savings account deposits, the M4 represents the most illiquid measure of money. The M0, by contrast, is the most liquid measure of the money supply.
