1) The private sector is experiencing falling savings. 2) The government is likely on the precipice of expanding its dis-saving in the form of greater deficits.
...
Not to state the obvious, but all else equal, if the Fed started shedding assets at $30 billion a month (or $360 billion a year), it would exhaust the entire stock of private savings. This doesn’t allow for larger government deficits. Given the current savings level, it is mathematically impossible for the Fed to shed assets at $50 billion/month. By 2019, as we are farther out from peak net savings rates set in 2015, it is likely the stock of private savings is smaller still, and hence the ability for the Fed to shed assets at a rate of $50 billion/month is utterly impossible. Net savings have fallen in the last 2 years from a peak of just over $700 billion to the current $355 billion. Will savings halve again in the next two years? If so, there is no mathematical way in the world the Fed can shed assets at the rate it outlined yesterday."

I tend to side with the uneducated who think the FED prints money out of thin air because it is closer to the truth of the matter of where real economic value exists moreso than the anachronistic mechanics of FED policy three card monte. When all is said and done, the FED took on toxic assets it will not be able to unload into a weak economy. The only hope it has is to sell the assets at face value in exchange for inflated dollars or hope the economy booms beyond everyone's expectations in the next two years. Sure hope the latter happens because otherwise the FED has done nothing but defer the pain of 2007 into the catastrophe of 2020.
