So the Fed has chosen to hold off on their goal of normalizing interest rates and the ECB has countered with the threat of extending their scheduled QE with more checks and more negative interest rates and the investment community wonders how long can this keep goin’ on. For a long time I suppose, as evidenced by history at least. ... zero bound interest rates destroy the savings function of capitalism, which is a necessary and in fact synchronous component of investment. Why that is true is not immediately apparent. If companies can borrow close to zero, why wouldn’t they invest the proceeds in the real economy? The evidence of recent years is that they have not. Instead they have plowed trillions into the financial economy as they buy back their own stock with a seemingly safe tax advantaged arbitrage. But more importantly, zero destroys existing business models such as life insurance company balance sheets and pension funds, which in turn are expected to use the proceeds to pay benefits for an aging boomer society. These assumed liabilities were based on the assumption that a balanced portfolio of stocks and bonds would return 7-8% over the long term. Now with corporate bonds at 2-3%, it is obvious that to pay for future health, retirement and insurance related benefits, stocks must appreciate by 10% a year to meet the targeted assumption. That, of course, is a stretch of some accountant’s or actuary’s imagination.
