The Federal Reserve just unveiled historic policy measures as a result of its December policy meeting.
The Fed announced QE4 as expected, but it surprised markets by adopting quantitative thresholds tying monetary policy to a 6.5 percent unemployment rate target, as long as inflation stays below 2.5 percent.
Adoption of quantitative thresholds was thought by many to be introduced sometime in 2013.
