Less Than Zero

When Interest Rates Go Negative


Imagine a bank that pays negative interest. Depositors are actually charged to keep their money in an account. Crazy as it sounds, several of Europe’s central banks have cut key interest rates below zero. For some, it’s a bid to reinvigorate an economy with other options exhausted. Others want to push foreigners to move their money somewhere else. Either way, it’s an unorthodox choice that has created distortions in financial markets. Some commercial banks have started to pass negative rates onto their customers. It’s a strategy that could ultimately backfire.

The Situation

The European Central Bank chose to experiment with negative rates before turning to a bond-buying program like those used in the U.S. and Japan. It was the first major central bank to venture into negative territory and its deposit rate reached minus 0.2 percent in September, a level President Mario Draghi said was the “lower bound.” It effectively punishes banks that hoard cash at the central bank instead of extending loans to businesses or to weaker lenders. Sweden is using a similar combination of negative rates and bond-buying. Denmark pushed rates deeper into negative territory to protect its currency’s peg to the euro and Switzerland moved its deposit rate below zero for the first time since the 1970s. Since central banks provide a benchmark for all borrowing costs, negative rates spread to a range of fixed-income securities. By the end of March, more than a quarter of the debt issued by euro zone governments had negative yields. That means investors holding to maturity won’t get all their money back. While banks are reluctant to pass on negative rates for fear of losing customers, UBS has complained that its earnings are being crimped and Julius Baer began to charge large depositors for holding their cash.

The Background

Negative interest rates are a sign of desperation, a signal that traditional policy options have proved ineffective and new limits need to be explored. Rates below zero have never been used in an economy as large as the euro area. While there is no guarantee that negative rates will be able to achieve what they are meant to do, Draghi pledged during the height of Europe’s sovereign debt crisis in 2012 to do “whatever it takes” to save the area’s common currency, signaling the ECB’s willingness to be innovative. Policy makers are trying to prevent a slide into deflation, or a spiral of falling prices that could derail the recovery. The euro zone is grappling with a shortage of credit and unemployment near its highest level since the currency bloc was formed in 1999.

The Argument

In theory, interest rates below zero should reduce borrowing costs for companies and households, driving demand for loans. In practice, there’s a risk that the policy might do more harm than good. Janet Yellen, the U.S. Federal Reserve chair, said at her confirmation hearing in November 2013 that even a deposit rate that’s positive but close to zero could disrupt the money markets that help fund financial institutions. If banks make more customers pay to hold their money, retails clients may put their cash under the mattress instead. When banks absorb the costs of negative rates themselves, it squeezes the profit margin between their lending and deposit rates, and might make them even less willing to lend. Ever-lower rates are also raising concern that countries are engaged in a currency war of competitive devaluations as investors shift their money to places where it earns more.
