Credit Creation: How does Commercial Banks Create Credit? by Supriya Guru Commercial Banks Advertisements: Creation of credit is one of the most outstanding functions of a modern bank. A bank has sometimes been called a factory for the manufacture of credit. How credit is created? It is an open secret that the banks do not keep cent per cent reserves against deposits in order to meet the demands of depositors. The bank is not a cloak room where you can keep your currency notes or coins and claim those very notes or coins back when you desire. It is generally understood that money received by the bank is meant to be advanced to others. A depositor has to be content simply with the bank’s promise or undertaking to pay him whenever he makes a demand. Thus the banks are able to do with a very small reserve, because all the depositors do not come to withdraw money simultaneously; some withdraw, while others deposit at the same time. The bank is thus enabled to erect a vast superstructure of credit on the basis of a small cash reserve. The bank is able to lend money and charge interest without parting with cash, as the bank loan creates simply a deposit or it creates a credit for the borrower. This is what is meant by creation of credit. Similarly, the bank buys securities and pays the seller with its own cheque which again is no cash; it is just a promise to pay cash. The

    Itshouldbefurthernotedthatthetotalexpansionofdepositsbythebankingsystemdependsuponthecashreserveratio(CRR).Thesmallerthecashreserveratiothelargetheexpansionofdepositsorcredit.Thus,intheabovecase,wenotedthat,giventhecashreserveratioof20%,thetotaldepositsexpansionfromthecashdepositsofRs.1,00,000,wasequaltoRs.5,00,000.Thusthetotaldepositsexpandedtowasfivetimestheoriginalcashdeposits.

    whererstandsforcashreserveratio.

    Thusdepositmultiplieristhereciprocalofcashreserveratio(CRR)whichwehavedenotedbyrinthemeasureofdepositmultiplier.

    Thus,whenthecashreserveratiois20%,thatis,0.20or1/5,thedepositmultiplier.

    =1/1/5=5

    Now,ifthecashreserveratioisraisedbyReserveBankto25percent,thatis,0.25,thedepositmultiplier,

    dm=1/0.25=1/1/4=4

  • Thus,thegreaterthecashreserveratio,thelowerwillbethevalueofdepositmultiplier.Inotherwords,increaseinthecashreserveratio(CRRorr)willleadtothecontractionofcreditcreatedbythebanks,andviceversa.

    Similarly,ifthecashreserveratiois10%,i.e.,1/10,thenthedepositsmultiplier=1/1/10=10.Inthiscaseinitialdepositsofsomecashamountinthebankingsystemwillleadtotentimesexpansioninthetotaldeposits.Figure11.1makescleartheprocessofdepositsexpansionbythebankingsystem.

  • dm=D/R

    or,inourfirstexample,dm=D/R=1/r=1/0.20=5

    Now,inouraboveexampletheprimarycashdepositsofRs.100,000ledtothecreationofdeposits(i.e.increaseincredit)equaltoRs.4,00,000bythebankingsystemitselfwhenmakingloansorcreatingcreditforbusinessmen.

    WhereCmrepresentscreditmultiplier

    Since
