Cumberland Advisors’ David Kotok points out that negative interest rate policy (NIRP) is spreading throughout the world, though he thinks that the Federal Reserve will do everything they can to not have to use it as a tool .. “The implications of lower and deepening NIRP policies are enormous. First, they ensure that interest rates will be at a zero or lower level for the rest of the decade in those jurisdictions. Imagine that we are seeing commitments now for the next two years, as publicly declared by the central banks. Think about how difficult it will be to ‘taper’ back up to zero from a NIRP. Our best guess is that these countries and those who join them are locked in a NIRP policy regime for the rest of the decade. At Cumberland, we are using an expanding NIRP as a policy assumption for our investment decision making .. The second implication of a spreading NIRP is that NIRP anywhere suppresses interest rates everywhere. The more NIRP we see, the more downward pressure on rates there will be in jurisdictions that are not under NIRP. We see that in the United States, where bond rates are positive numbers but are continually pressured to lower and lower levels. Those investors who do not understand NIRP have missed a huge rally in bonds. At Cumberland, we have invested in that rally. Only now are we beginning (and we stress the word beginning) to take some of that profit and redeploy it .. The third implication of NIRP is that it changes a key characteristic of money. Money is still a unit of measure. Money is still a facilitator of commercial exchange. But NIRP alters behaviors when it comes to money’s being a ‘store of value.’ .. The fourth implication of NIRP plays out in the borrowing arena. When a borrower can finance at near zero and when that borrower is assuming that NIRP will continue for a prolonged period, that borrower changes the way debt is viewed. Essentially the use of money becomes free or nearly free. .. The fifth and a huge implication of NIRP is its impact on asset prices. Remember, NIRP assures that the riskless rate will be zero or lower for years to come. With that assumption in place, the prices of assets rise and rise. The longer the duration of those assets, the higher the prices can rise .. NIRP is bullish for asset prices. It is repressive for traditional savers.”
