© OnlineTexts.com p. 30 Money Creation example Emily deposits $100,000 in cash into First Federal. M1=$1,100,000

© OnlineTexts.com p. 31 Money Creation example First Federal lends $90,000 to Bob. M1=$1,100,000 + $90,000 = $1,190,000

© OnlineTexts.com p. 32 Money Creation example Bob deposits $90,000 into Second Federal. M1=$1,100,000 + $90,000 = $1,190,000

© OnlineTexts.com p. 33 Money Creation example Second Federal lends $81,000 to Amy. M1=$1,100,000 + $90,000 + $81,000 = $1,271,000

© OnlineTexts.com p. 34 The Money Multiplier The money multiplier formula: determines the maximum amount of money that can be created from Emily's initial deposit of $100,000. In this example, the money multiplier is equal to 1/10% = 1/.10 = 10, so the maximum change in the money supply = 10 x $90,000 = $900,000.

© OnlineTexts.com p. 35 The Money Multiplier This money multiplier formula calculates the maximum possible expansion of M1 because it assumes that: –everyone deposits their new loans into a checking account at a bank, and –banks hold no excess reserves. Note that the money creation process works exactly the same in reverse.
