What's Really Driving ZIRP?

Recently I've written about the head-scratching, never-ending, multi-decade decline in long-term interest rates (see chart below). Who cares? Well, just about anybody if you bear in mind the way interest rates impact the cost of borrowing on mortgages, credit cards, automobiles, corporate bonds, savings accounts and practically every other financial instrument you can imagine. Simplistic conventional thinking explains the race to 0% global interest rates by the loose monetary Quantitative Easing (QE) policies of the Federal Reserve. But validating that line of thinking becomes more challenging once you consider that QE ended months ago. And contrary to common belief, rates declined further rather than climb higher after QE’s completion.
