Roubini: The Negative Way to Growth — Why Are So Many Investors Willing To Lose So Much Money?

Monetary policy has become increasingly unconventional in the last six years, with central banks implementing zero-interest-rate policies, quantitative easing, credit easing, forward guidance, and unlimited exchange-rate intervention. But now we have come to the most unconventional policy tool of them all: negative nominal interest rates.

Such rates currently prevail in the eurozone, Switzerland, Denmark, and Sweden. And it is not just short-term policy rates that are now negative in nominal terms: about $3 trillion of assets in Europe and Japan, at maturities as long as ten years (in the case of Swiss government bonds), now have negative interest rates.

At first blush, this seems absurd: Why would anyone want to lend money for a negative nominal return when they could simply hold on to the cash and at least not lose in nominal terms?  In fact, investors have long accepted real (inflation-adjusted) negative returns. When you hold a checking or current account in your bank at a zero interest rate – as most people do in advanced economies – the real return is negative (the nominal zero return minus inflation): a year from now, your cash balances buy you less goods than they do today. And if you consider the fees that many banks impose on these accounts, the effective nominal return was alreadynegative even before central banks went for negative nominal rates.

In other words, negative nominal rates merely make your return more negative than it already was.
