From Bloomberg:

Federal Reserve policy makers are considering adopting a new benchmark interest rate to replace the one they’ve used for the last two decades.

The central bank has been unable to control the federal funds rate since the September 2008 bankruptcy of Lehman Brothers Holdings Inc., when it began flooding financial markets with $1 trillion to prevent the economy from collapsing. Officials, who start a two-day meeting today, have said they may replace or supplement the fed funds rate with interest paid on excess bank reserves.

“One option you might want to consider is that our policy rate is the interest rate on excess reserves and we let the fed funds rate trade with some spread to that,” Richmond Fed President Jeffrey Lacker told reporters on Jan. 8 in Linthicum, Maryland.

The central bank needs to have an effective policy rate in place when it starts to raise interest rates from record lows to keep inflation in check, said Marvin Goodfriend, a former Fed economist. Policy makers are concerned that the Fed funds rate, at which banks borrow from each other in the overnight market, may fail to meet the new target, damaging their credibility and their ability to control inflation as the economy recovers.  More here.
