Assume a simultaneous open market purchase of 100 million from the Bank of England and a repayment of a discount loan of 5 million from Bank A to the Bank of England. Show the overall change in their balance sheets and discuss the implications for the monetary base.If the currency ratio is 0.6, the excess reserves ratio is 0.3, and the required reserve ratio is 0.1, compute the change in the money supply and comment on your result. If the Bank of England would prefer the money supply to change by the amount it would have if it was not for the repayment of the discount loan, how much the Bank of England needs to change the required reserve ratio?
