Climate change – bzirc monetary policy

As investors we get used to living within certain recognised bounds. For example, it has been commonly assumed that interest rates cannot be sub-zero. There has been the odd historical quirk when we’ve seen negative rates (Switzerland in the 1970s), but that’s more for amusement than general investment consumption. However, there now appears to be the potential for a major investment climate change.

There are already plenty of bond markets now living in the sub zero ice age, such as Switzerland, Denmark, Germany, Finland and the Netherlands. In these cases, the existence of negative rates could be down to the desire to express a currency or re-denomination view (as Mike previously wrote), so may be seen as a by-product of external factors and not of domestic monetary policy. However, there is now the potential for G7 monetary policy to enter the previously unbelievable reality of official sub-zero rates.

Many G7 economies have implemented very low rates and quantitative easing for a number of years, yet still appear to be in the economic doldrums with high unemployment, low growth and limited fiscal room. It could now be time for a significant change in the investment text book as central banks experiment with rates below zero.

Theoretically, a negative interest rate sounds simple – you put £100 in the bank and you get £99 back a year later if the rate is -1%. A  rational investor would of course have the alternative of simply keeping their cash under the mattress and not suffering the negative rate, although the incentive to behave rationally would be limited by the administrative burden and security risk of holding cash.  The central bank could simply limit this activity by basically not printing enough cash. Therefore the vast majority of money would have to be held electronically and could therefore suffer a penal negative rate. Implementation of sub zero rates is possible.

From a central bank’s point of view this should be stimulative, as it would discourage saving and encourage consumption like any traditional interest rate cut. At the extreme you could create exceptionally low, zero, or even negative borrowing rates.

The challenges faced by central banks and governments are still there despite traditional and unconventional policy action. Maybe it will soon be time to use the conventional tool of cutting interest rates in an unconventional way by making them negative. The next step to be taken by the authorities might mean economies working in a below zero interest rate climate (bzirc monetary policy).
