In a recent newsletter John Mauldin wrote: “It is monetary policy madness to raise rates and undertake quantitative tightening at the same time.” However, this is exactly what the Fed plans to do in 2018. Has the Fed gone mad?

If mad is defined as diverging in an irrational way from normal practice then the answer to the above question is no. The Fed is following the same rule book it has always followed.

It should first be understood that earlier rate-hiking campaigns were always accompanied by quantitative tightening (QT). Otherwise, how could the Fed have caused its targeted interest rate (the Fed Funds rate) to rise? The Fed is powerful, but not powerful enough to command the interest rate to perform in a certain way. Instead, it has always manipulated the rate upward by reducing the supply of reserves to the banking system via a process that also reduces the money supply within the economy; that is, via QT. In other words, far from there being something unusual about the Fed simultaneously raising rates and undertaking QT, it is standard procedure.

What’s unusual about the current cycle is the scale. Having created orders of magnitude more money and bank reserves than normal during the easing part of the cycle the Fed must now implement QT on a much larger scale than ever before. At least, that’s what the Fed must do if it follows its rule book.

A plausible argument can be made that the Fed should now deviate from its rule book, but the argument isn’t that the economy is too weak to cope with tighter monetary policy. The correct argument is that the damage in the form of misdirected investment and resource wastage was done by the earlier quantitative easing (QE) programs and this damage cannot be undone or even mitigated by deflating the money supply. In effect, the incredibly loose monetary policy of 2008-2014 has made a painful economic denouement inevitable. At this point, reducing the money supply — as opposed to stopping the inflation of the money supply, which would be beneficial as it would prevent new mal-investment from being added to the pile — would exacerbate the pain for no good reason.
