Traditional economic theory suggests that savers would rather hold cash than lose money by leaving it in a bank. Positive interest rates benefit both savers and borrowers. However, in the past few years, central banks have been rethinking the idea of the zero lower bound and pushing interest rates into the negative. In 2009 and 2010, Sweden led the way as the first nation to set negative interest rates following the financial crisis. Switzerland and Denmark have since followed suit. Last year, even the European Central Bank issued a negative interest rate. Since the absolute value of these interest rates is so low (mostly around -0.75% and -0.85%), there has not been a huge amount of backlash since the negative rates have in fact benefited these nations’ economies. Overall, this technique has given central banks the ability to change the way that they conduct policy. Having the ability to set negative interest rates is enabled by such low inflation of recent years.
