population is mostly illiterate, and even were it otherwise it could not have availed itself of the cheque system, because Indian banks refuse to conduct their business in any other medium but English. Besides, the growth of the cheque system presupposes a widespread network of banks, a condition which is far from being fulfilled in India. In the absence of banking, a cheque is the worst instrument that could be handled. If not presented within a certain time, a cheque may become stale and valuless, and is therefore inferior to a note as a store of wealth. In such circumstances as these, it is no wonder that in India cheques did not come into being on a sufficiently large scale to amend the inelasticity of the notes.
But even if Indian banks had succeeded in making use of credit in a form other than that of notes, they could not have eased the money market to the same extent as the English banks have been able to do. One of the incidents of banking consists in the liability of banks to pay cash on demand. If all their deposits were received in cash this liability would involve no risk. As a matter of fact, a larger part of their deposits consists of bills which they make it their business to undertake to pay in cash. One of the first things, therefore, that a banker has to look to is the proportion which his cash deposits bear to his credit deposits. Now, this proportion may be adversely affected either by an increase in his credit deposits or by diminution in his cash deposits. In either case his ability to pay cash is pro tanto weakened by lowering the ratio of his total cash to his total liabilities. Against an undue expansion of credit a banker may effectually guard himself. But, notwithstanding the development of the cheque system, there is always lurking the possibility of withdrawal of some cash at some time or other. A banker must, therefore, provide by keeping on hand a certain minimum reserve. How large should be the reserve depends upon what the possibilities for the withdrawal of cash are. The point is that to the extent of the reserve the power of the bank to grant credit is curtailed. If the reserve of the bank is already at the minimum it must stop discounting or must strengthen its position by recovering the cash withdrawn from its coffers. Now, it is obvious that if the amount of money withdrawn is kept in the current of business where the banks can get at it, they of course can strengthen their position again immediately, and not only always keep themselves well away from the danger line of minimum reserve, but be always prepared to meet the needs
