Here, C refers to currency and DD to net demand deposits. The term net refers to that part of the demand deposits which can be withdrawn through cheques by public. Net demand deposits can be obtained by subtracting inter-bank deposits from total demand deposits. The inter-bank deposits refer to deposits of one bank held with other bank(s). Such deposits can’t be withdrawn by public.

(b) Broader Concept:

The broader concept of money supply is based not only on the medium of exchange function of money but also on the store value function of it. Accordingly, all assets possessing liquidity high enough to serve as a store of value along with the currency and the demand deposits of public comprise money supply in broader sense. The expression for money supply under this concept can be made as:

Ms = C + DD + TD

Here, TD refers to time deposits (fixed deposits) with commercial banks as well as those with the post offices while DD, to the net demand deposits. Note that the time deposits qualify as a component of money supply in broader sense.
