This Is How QE Really Works
QE2 Is Equivalent to Issuing Treasury Bills. In actual fact, all QE2 does is drain the real economy of interest income by swapping an interest-bearing government liability for a non-interest bearing government liability. This decreases aggregate demand in the economy. So the real economy effects of QE are to slightly lower aggregate demand. This is offset by changing interest rate expectations, which alter private portfolio preferences and risk premia, leading to credit growth, leverage and speculation, forces which should pump up the real economy. The Fed had intended to lower interest rates via the lowered risk premia. To date, the Fed has lowered risk premia. But this has also provided the tender for speculation and leverage. Moreover, the Fed has also raised inflation expectations to boot, causing interest rates to rise and working at cross-purposes with the lowered risk premia. Thus, QE2 has only been successful insofar as it has increased business credit and raised asset prices. In my view, QE2 has been a bust as it adds volatility to the system and will have negative unintended consequences down the line.
