Would an increase in money supply by the fed cause a larger or smaller reserve ratio?

Answer 1

An increase in the money supply does not affect the reserve ratio... but does increase the aggregrate reserves.

Answer 2

The connection is the other way: when the fed changes the reserve ratio, it changes the money supply accordingly: higher reserve requirements cause tighter money (a decrease in the money supply), etc.
