Q) Open Market Operations decrease the supply of base money by:
a. Selling Government Bonds
b. Selling Gold
c. Reducing Foreign Currency Holdings
d. All of the above
The answer provided by Amit Sir is (d). But shouldn't it be (a) as gold and foreign currency don't constitute as a part of the open market operations.
Monetary authority ie central banks are sole reserver of gold nd currency of a nation.....so when it transacts gold and currency it effects nation's money supply....
But as far as I've read the trading of gold by CB isn't a part of Open Market Operations. I mean that is what is mentioned in Blanchard, that it is an "Open Market for Bonds".
Actually central bank requires commercial banks to keep gold as a reserve requirement with central bank...now when this requirement fluctuates the central bank's reserves for gold fluctuates leading to fluctuation in money supply....
