The FOMC has instructed the FRBNY Trading Desk to purchase $920 miltion in U.S. Treasury securities. The Federal Reserve has currently set the reserve requirement at 10 percent of transaction deposits. Assume U.S, banks withdraw all excess reserves and give out loans. o. Assume also that borrowers eventually return all of these funds to their banks in the form of transaction deposits. What is the full effect of this purchase on bank deposits and the money supply? b. What is the full effect of this purchase on bank deposits and the money supply if borrowers return only 90 percent of these funds to their banks in the form of transaction deposits? (For all requirements, enter your onswers in billions. Round your final onswers to 2 decimal places. (i.e., 5,500,000,000 should be entered as 5.50).)
