The impact of the return to lagged reserve requirements on the federal funds market

We examine the impact on the settlement Wednesday effect in daily fed funds rates following the change from contemporaneous reserve requirements (CRR) to lagged reserve requirements (LRR). The Federal Reserve changed from CRR to LRR, in part, to make it easier for banks to settle their reserve accounts. Our hypothesis is that the switch to LRR will reduce the demand for reserves on settlement Wednesdays, thus reducing the settlement Wednesday effect in fed funds rates. Our empirical results provide strong support for our hypothesis.
