Ultimately though, in broader more subjective terms, it is capitalism itself that is threatened by the ongoing Martingale strategies of central banks. As central bank purchases grow, and negative/zero interest rate policies persist, they will increasingly inhibit capitalism from carrying out its primary function — the effective allocation of resources based upon return relative to risk. At PIMCO Christmas parties past, I used to praise my fellow employees for their part in the ongoing process of capital allocation. Yes, we were prosperous, I admitted, but we were helping the global economy and over 8 billion people to prosper as well — eliminating the deadwood, fostering new growth, and anticipating future headwinds. That can no longer be true — at PIMCO, Janus, or any other financial institution. Central bankers have fostered a casino like atmosphere where savers/investors are presented with a Hobson's Choice, or perhaps a more damaging Sophie's Choice of participating (or not) in markets previously beyond prior imagination. Investors/savers are now scrappin' like mongrel dogs for tidbits of return at the zero bound. This cannot end well.
