Low interest rates revived the economy, but now we're all suffering for it

A 35-year-old needs to invest £125,000 to earn a pension of £35,000 when the interest rate is 5 per cent. If it's 2 per cent, they'll need to save £400,000

I could hardly believe that a politician would blame low interest rates for the success of a far right political party. Least of all that it would be the eminently sensible Wolfgang Schäuble, Germany’s minister of finance, who has held office since 2009. Yet earlier this month he publically blamed the cheap money policy of the European Central Bank (ECB) for contributing to the rise of the country's right-wing anti-immigration party, Alternative for Germany (AfD).

“I told Mario Draghi (president of the ECB),” said Mr. Schäuble, “be very proud: you can attribute 50 per cent of the results of a party that seems to be new and successful in Germany to the design of this policy.”

Founded only in 2013, the AfD has recently gained representation in eight German state parliaments.

In explanation, the transport minister, Alexander Dobrindt, told Die Welt newspaper: “The ECB is following a very risky course. The disappearance of interest rates creates a gaping hole in citizens’ old age preparations.”

There is the connection. The older generations, who often dislike immigration, have also found that a lifetime of careful saving has brought them little reward. No wonder they make their protest by voting for an anti-immigration party.

Note that Mr. Dobrindt referred to “the disappearance of interest rates”. That hasn’t yet happened here. But it is still a shock, however, to discover how meagre they are. Go into Barclays, for example, and you will find that the bank will give you 0.25 per cent per annum on sums of less than £25,000. So you place £20,000 for a year and you earn – £50 in interest.

At least this is a positive rate. But if you are a citizen of the Eurozone, or of Japan, or of Sweden, or of Switzerland or Denmark, a group of countries that account for one quarter of the world economy, the situation is even worse. There the banks are actually charging customers for the privilege of depositing money with them. In other words, interest rates are negative. You don’t get your £20,000 back, but a mere £19,950.

It isn’t only German politicians who are concerned about low or negative interest rates. This week Larry Fink, the chief executive of the investment managers Blackrock, which looks after more funds than any other firm, revealed his disquiet in an annual letter to shareholders.

Fink said that the adoption of negative interest rates was “particularly worrying”. He commented that investors were being forced to take on more risk in order to obtain higher returns. And this often meant that they had to sacrifice the certainty that they could find buyers when they wanted to sell their assets. Fink rightly calls this ‘a potentially dangerous combination for retirement savers’.

But what about people, for instance, in their thirties and saving up for retirement. Fink gives this chilling calculation. A 35-year-old looking to generate an income of £35,000 per year for a retirement beginning at age 65 would need to invest £125,000 today in a 5 per cent interest rate environment. In a 2 per cent interest rate environment, however, that individual would need to invest £400,000 (3.2 times as much) to achieve the same outcome when he or she stops working.

If the disadvantages of low interest rates are so daunting, what then are the supposed advantages? That is matter that will be debated at the IMF’s annual spring meetings this week in Washington.

Three officials have written a blog that seeks to balance the pros and cons. They “tentatively” conclude that, overall, negative interest rates help deliver additional monetary stimulus and easier financial conditions, which support demand and price stability. But, they add, “there are limits on how far and for how long negative policy rates can go.” I call that lukewarm support.

In fact, taking together the reservations expressed above and the analysis presented by the IMF paper, the drawbacks of low or negative interest rates fall into three groups.

First, savers may prefer physical cash to bank deposits, which is bad for economic activity. The IMF paper discusses using bank vaults or non-bank vaults for holding cash safely. Second, the policy may encourage excessive risk taking both by banks and by individuals. And third, as the IMF comments, if low or negative rates persist they could undermine the viability of life insurance, pensions and other savings vehicles.

The truth is that governments no longer have the means to revive economic activity. Gimmicks such as negative interest rates could easily do as much harm as good.
