Cashless Australia, Fractional Reserve Banking and the Capital Adequacy Ratio By James Reed

I am no expert on economics, but the thought just popped into my head another reason why the banks may want to eliminate cash. Fractional reserve banking operates as follows: “Fractional-reserve banking is the system of banking operating in almost all countries worldwide, under which banks that take deposits from the public are required to hold a proportion of their deposit liabilities in liquid assets as a reserve, and are at liberty to lend the remainder to borrowers. Bank reserves are held as cash in the bank or as balances in the bank's account at the central bank. The country's central bank determines the minimum amount that banks must hold in liquid assets, called the "reserve requirement" or "reserve ratio". Most commercial banks hold more than this minimum amount as excess reserves.”

Note that the bank reserves are held in cash as stated above, the main liquid asset. That puts a small brake upon the creation of credit out of nothing by the banks. But if cash is eliminated, is there any brake left upon the banksters creation of credit? I may well be wrong, and no doubt are, but I can’t see any limitations any more. People more knowledgeable  than me, and there are many, may choose to discuss this.
