<p>In April 2011, the money supply was estimated to be 52 million hurls.
At the same time, bank reserves were 6.24 million hurls and the
reserve requirement was 12 percent. The banking industry, being
“loaned up,” lobbied the Congress to cut the reserve ratio. The
Congress yielded and cut required reserves to 10 percent. What is
the impact on the money supply?</p>

<p>From my calculation, a decrease in the required reserve ratio would mean that the reserves of 6.24 million will support 62.4 million hurl. Does this means that the money supply increases by 10.4 million?</p>

To answer a real world question there is insufficient information.  April 2011 banks are not reserve constrained anyway in most major economies. Also are they paying interest on reserve balance? How well capitalised are the banks?
