An un-save-ry business

The Bank of England’s action yesterday to ease monetary policy by driving interest rates deeper into all-time low territory has both positive and negative aspects. On the plus side, the fact that the central bank has acted pre-emptively illustrates that it is aware of the potential economic consequences of the Brexit vote. Another welcome innovation was the Term Funding Scheme, which is designed to ensure that banks can obtain funding at a cost “close to Bank Rate” which in turn means that they can pass on a significant chunk of the lower interest rates to their customers. As the BoE pointed out, the all-in cost of funding in the wholesale market is close to 100 bps and the TFS will ensure that banks can access funding at between 25 and 50 bps, depending on their lending volume. In this way, banks will be able to avoid the margin compression which is such a problem in a low rate environment, and hopefully will prevent many of the distortions which have been such a feature of the euro zone in recent months.

Two other elements of the package were an additional £60bn of gilt purchases and up to £10bn of corporate bond purchases, both of which were designed to further reduce yields, thereby giving additional monetary stimulus, and triggering portfolio balancing by forcing investors out of bonds and into other assets. Perhaps the most impressive part of the package was that it demonstrated a degree of joined-up thinking. The distortionary effect of low interest rates on banks’ business models is a well-known problem and the BoE clearly went some way towards addressing this crucial issue in a way which the ECB has not.

But it is not all good news. Driving interest rates ever lower is placing a serious burden on savers and is most certainly having an adverse effect on our retirement incomes. When pressed on this during the press conference, Governor Carney basically suggested that it is a choice between sacrificing savers and putting lots of people out of work. I think this is a false choice. For one thing, the Brexit fallout represents an uncertainty shock which is not readily amenable to monetary solutions. Lower borrowing costs will not determine whether Nissan decides to continue investing in its British operations. Indeed, if the Brexit negotiations go awry, Nissan could put lots of people out of work AND savers retirement incomes will still be under pressure.

What is more pernicious is that many policymakers, past and present, argue that more monetary easing does no harm so why not just do it. But that is also false. As noted above, low rates hurt savers. And there is another problem: By national accounting definition the current account deficit represents the difference between domestic saving and investment. If we reduce the incentive so save, so the economy can only invest by borrowing from the rest of the world – and the UK just happens to have one of the biggest current account deficits in the OECD (exceeded only by Colombia). So you still think that low rates are a good idea?

Another thing that concerns me is that central bankers have been loath to tighten monetary policy even once a recovery appears to be underway. There is thus a real risk that we get sucked into a world of low interest rates for far longer than is necessary, with all the attendant risks outlined above. And finally, there is general recognition that the Brexit problem is by no means as serious as the shock in the wake of the Lehman’s bust. So why then has the BoE implemented a monetary stance which is even more expansionary than we saw in 2009?

Maybe I am being a little too harsh. But the problem is that monetary policy remains the only game in town, given that the previous occupant of 11 Downing Street pursued an aggressive austerity policy which left no room for fiscal expansion. Many economists would welcome a change of policy on this front. And if over the course of the next year or two we do see a more activist fiscal approach, the BoE should be far less squeamish about raising interest rates. After all, savers could do with a break after seven years of squeeze.
