After nearly five years of negative interest rates, the oldest central bank in the world has had enough.

Swedens Riksbank hiked its key interest rate back to 0% on Thursday, becoming the first central bank to enter negative territory and then come back up amid growing concerns that harmful side effects are outweighing the benefits of such policies.

Its part of a general unease about having rates in negative territory, David Oxley, senior Europe economist at Capital Economics, told me.

The worlds best pension system is being pushed to the brink

Background: Central bankers have conducted an unprecedented experiment since the 2008 financial crisis. To juice a sluggish global economic recovery, theyve pushed interest rates to their lowest points in history. In Europe and Japan, rates have been in negative territory since 2014 and 2016, respectively. Swedens main rate went negative in 2015.

But fears about the adverse impact of these policies have been building. Its beenpainful for banks, which have to pay to park their money with central banks instead of collecting interest. Savers have also been penalized, and its added to pressure onpension funds.

Such concerns explain the Riksbank vote to quit negative rates though Oxley noted that Swedens banks have fared better than others in Europe.

It has become pretty clear over recent meetings that policymakers have become warier about negative rates becoming a more permanent state of affairs, and the effect that might have on peoples expectations, ING economists told clients Thursday.

An outlier: Apart from the Riksbank, central banks dont seem to agree that now is the time to be raising interest rates. The Bank of Japan kept interest rates on hold Thursday. The Bank of England is expected to make the same call later in the day.
