Most of the time QE is inflationary, but when the Fed engaged in the latest round they actually made it deflationary because the banks could make risk-free profits by parking excess funds at the Fed and earning interest. As a result, Fed deposits from banks went up 1,000x and all that cash went into buying T-bills (gov't spending) keeping rates low but doing nothing to stimulate the economy. Of course, those who are 'in the know' got to position themselves to profit from the inevitable deflation in commodities and a stronger dollar.
Now, the Fed needs to get this money-ball rolling by increasing short-term rates so that the banks start pulling their money out of the Fed and lending it. This will generate an increase in inflation and a weaker dollar because interest rates are still too low to siphon off any meaningful amount of QE. Expect commodities prices and inflation to start increasing as the Fed raises rates. Hopefully, the Fed can effectively manage the inflation that is coming.
Again, those who are 'in the know' are positioning themselves to profit from future inflation. Prolly the same people who are buying all of these oil assets that are on sale due to the oil price collapse.
And that is how the central-banking game is played... over and over and over and...
