Chapter 16: Q.9 (page 436)
Why are repurchase agreements used to conduct most short-term monetary policy operations, rather than the simple, outright purchase and sale of securities?
Short Answer
On account of the repurchase understanding, the Fed offers government protections to banks, for the most part on a short-term premise, and repurchases them the next day at a marginally more exorbitant cost. This assists the Fed with effectively changing open market activities in light of day to day conditions.
