Answer:
Step-by-step explanation
U.S government with the help of central bank they decide how interset rates going to be if they have to be increased or decreased
Central bank do two thing it may increase or decrease ....what ??
CRR or SLR
CRR is also know as current reserve ratio which means that certain amount of money banks has to deposite in the central bank of their deposit and if government increase that CRR RATE means central bank adopted "tight money policy " or in simple terms they want to decrease the money supply from market so as to control inflation and if the decrease the CRR means they want to flow market with money supply .
So if CRR is increased means less money banks had to deposit in the central bank then they have less money with them to give as loan. so , interest rate is increase
And if CRR is increased the vice a virsa will happen
SLR - statuary liquidity fund
This is the sum of money , gold bank had to keep with themself as a emergency fund for bank run
It apply same way as of CRR it increase interest rate increase and if decrease then decrease
