Are we better off with "QE", the ultra-accommodative monetary policy pursued by major central banks around the world? Is it "mission accomplished" or are we facing a "ticking time bomb"? Are extreme characterizations even warranted to describe the unconventional monetary policy of recent years, and what are implications for investors?

The Good

When interest rates are at or near zero and central bankers want to provide more "monetary accommodation," it is not clear that negative interest rates are the answer.  The term "quantitative easing" or "QE" was coined to describe the purchases by of government bonds by central banks. It was combined with "forward guidance" which signaled rates would stay low for an extended period; in our assessment the key goal of both policies was to lower long-term rates (historically, central banks control short-term rates, but leave longer term rates up to the market to determine). Doing so, so the logic goes, would provide the desired "accommodation." There is an index that tries to create a Fed Funds rate incorporating QE:

Note that this index suggests that we have had substantial tightening take place since the 'end' of QE.

Did I just write "the end of QE"? Last time I checked, the Fed has stopped increasing to its arsenal of bonds, but has continued to reinvest proceeds from maturing securities on its balance sheet. The Fed owns these bonds; that is, they sit on the asset side of the Fed's balance sheet. This is not the place to pass judgment on the methodology of the index, but want to show how at least some economists look at QE.

It's our understanding that central bankers never want to appear out of ammunition. As such, QE gives them a tool that they believe does the equivalent of 'lowering' rates at any time should, in their assessment, that be warranted.

The Bad
While the Fed's measures may have prevented more firms, possibly even the financial system as a whole, from imploding in the aftermath of the 2008 financial crisis, the economy has hardly fired from all cylinders ever since. Historically, a sharp contraction is usually followed by a steep recovery; this time, however, the recovery has been rather lackluster.  Amongst the reasons for the lackluster recovery may be:

• Rates aren't so low. While nominal rates are low, inflation is also low. More so, as the chart above suggests, there might have been substantial tightening since the 'end of QE' was announced. In Europe, ECB chief Draghi suggests real interest rates (nominal rates net of inflation) are higher now than twenty years ago. It's beyond the scope of the analysis here to comment on this argument.

• Constrained banks. Â Policy makers wanted banks to take less risk. That may be a good policy goal, but it comes at a price: in a credit-driven society, when those providing credit are constrained, one ought to expect lower growth. We agree with this argument in principle, but would like to point out that it's been lack of demand for credit, not the lack of supply that's been key to holding back economic growth. One can lead a horse to water, but you can't make it drink; similarly, central banks can make credit cheap, but can't force consumers and businesses to borrow.

• Headwinds imposed by taxes and regulation. There is an argument to be made, and I sympathize with it, that we've had a tremendous increase in regulations, making it less attractive to invest. The counter-argument to this is that there's a political camp that has "always" complained about too much regulation and that there's nothing new here. I beg to differ and concur with the camp that suggests this may well be the biggest impediment to growth, but note that it is most unfortunate that this debate turns political.

• Lackluster global growth / the strong dollar. I group those two into one not because they are identical, but because they both reflect what may be a global attitude that it's others that should fix their problems to help us. I beg to differ: while there may be headwinds caused by global factors, we can foremost control domestic ones. Our policy makers may be well served to focus on what they can control rather than blame others. Having said that, I allege that it is a defining symptom of the environment we are in that policy makers increasingly seek to blame others (this is a non-partisan jab at policy makers globally, not merely U.S. elections).

• Demographics. As society ages, there may be less economic growth because labor force growth slows or even declines. I agree that demographics may be under-estimated, but the U.S. fares far better than many other advanced economies, yet the U.S. is plagued by a declining labor force participation rate as well. That said, U.S. elderly Americans are working (they don't have enough savings to retire); it's folks in their prime years that are dropping out of the work force that, in my assessment, is a bigger problem. Part of the challenge is an increasing number of Americans on disability. Just recently, I spoke with someone who lamented that he is sitting at home bored, but couldn't go back to work, as he would lose his disability benefits. The increase in disability benefits has held growth back.

• Technology. A tune that I increasingly hear is that “everything worth inventing has been invented." Similarly pessimistic reasons make it to the headlines every couple of decades. I don't buy it. Quantum computing could provide an exponential boost to our computing power. Technology could solve challenge posed by climate change. Without a doubt in my mind, there can be lots of improvements in healthcare. Â

• Globalization. In my view, globalization doesn't hold growth back, but it provides a more level playing field. However, that's bad news for those who had in the past demanded top dollars for their services, when there are a billion others offering to provide the same service at a lower price. Technology, in some ways, provides the same challenge, as ever more complex tasks can be outsourced to machines. Those are challenges, and in my view, policy makers on both the left and the right of the political spectrum have done a poor job helping society keep pace and adjust.

• Lack of vision. At the peak of the Eurozone debt crisis, Eurogroup head Dijsselbloem pointed out that one cannot expect investors to buy bonds of peripheral Eurozone countries if policy makers don't provide a vision of where they should be in ten years. I believe such criticism is well warranted not just for the Eurozone, but for much of the developed world, both with regard to fiscal and monetary policy. In our assessment, the lack of clarity on future policy is a headwind to growth.

• Low productivity. In a speech in 2005, Janet Yellen, then President of the St. Francisco Fed, argued low productivity warrants higher rates. Now as Fed Chair, we believe she argues the opposite. The apparent contradiction may be found in the fact the low productivity is the result of other policies, not a variable that can be manipulated, even if some economists may be tempted to do so. At a debate amongst the living (current and former) Fed Chairs at the International House on April 7, former Fed Chair Alan Greenspan argued an economy that's close to full employment must be boosted by facilitating greater productivity, which, according to him, is facilitated by making it more attractive for businesses to invest. This is in contrast to former Fed Chair Bernanke, who joins what we see as a growing chorus of people that seemingly argue for greater fiscal spending. Greenspan disagrees, arguing greater fiscal spending may only lead to a temporary boost in growth, but will lead to both higher deficits and wage pressures (given that we are near full employment).

• Low rates. In contrast to the first bullet point, low rates themselves may be part of the problem. In my assessment, monetary policy has facilitated unproductive businesses to stick around when many of them should have failed. Had they been allowed to fail, the downturn would have been more severe, but it would have allowed a market based re-allocation of resources to more productive businesses. Differently said, in my humble opinion, central banks are guilty of disrupting the creative destruction mechanism capitalism relies on; we are paying the price for this, amongst others, through lower productivity and lower growth. More broadly speaking, we allege that capital misallocation is fostered by rates that may be too low, also leading to subpar growth.
Why did I just list a laundry list of possible impediments to growth? With the exception of the first and the last, they have little, if anything to do with monetary policy. Yet, we believe today's breed of central bankers often feels responsible to do whatever they can to help out the economy, even if monetary policy cannot fix the problems at hand. QE might just be too tempting a tool; one, however, that cannot necessarily provide the cure that's needed.

The Ugly
The ugly part comes in when thinking about how to exit QE, if at all. The Fed ought to be focused on inflation & maximum sustainable growth, yet, the Fed to us appears to be increasingly focused on financial markets. Why should the Fed care about how the markets react? A former Fed official told me that the Fed may only need to be concerned about market reaction if it had created an asset bubble. He left it at that without saying that the Fed indeed created an asset bubble.
