Assume that the banking system has total reserves of $180 billion. assume also that required reserves are 20 percent of checking deposits and that banks hold no excess reserves and households hold no currency. the new money multiplier is __ , and the money supply is to $ billion. suppose the fed raises required reserves to 25
percent of deposits.
the new money multiplier , and the money supply ( increases/ decreases) $billion.

(a) 5; $900 billion

(b) 4; decreases to $720 billion

Explanation:

(a) Since the reserve ratio is 20%,

the money multiplier will be:

= 1 ÷ Required reserve ratio

= 1 ÷ 0.2

= 5

Money Supply = Total Reserves × (Money Multiplier)

                         = 180 × 5

                         = $900 billion

(b) Since the new reserve ratio is 25%,

the new money multiplier will be:

= 1 ÷ Required reserve ratio

= 1 ÷ 0.25

= 4

New reserves for money supply of $1000 billion = $900 ÷ 4

                                                                                 = $225 billion

Change in reserves = 225 - 180

                                 = $45 billion

New money supply to maintain $45 billion reserves:

= 45 × 4

= $180 Billion

Change in money supply = 900 - 180

                                          = $720 billion

answer: b 56, 250

explanation:

the answer is either c or b, i cant be to sure tho.
