When the Central Bank raises the required reserve/deposit ratio, banks must hold back more of its reserves as required reserves. This means less lending and a decrease of the money supply. In this case, the original money supply was 2,000 + (300/ 0.10)= 5,000 econs. The new money supply is 2,000 + (300/ 0.15)= 4,000 econs.

In Macroland, Currency Held by the Public Is 2,000 Econs
