Money for Nothing

BRUSSELS – The developed world seems to be moving toward a long-term zero-interest-rate environment. Though the United States, the United Kingdom, Japan, and the eurozone have kept central-bank policy rates at zero for several years already, the perception that this was a temporary aberration meant that medium- to long-term rates remained substantial. But this may be changing, especially in the eurozone.

Strictly speaking, zero rates are observed only for nominal, medium-term debt that is perceived to be riskless. But, throughout the eurozone, rates are close to zero – and negative for a substantial share of government debt – and are expected to remain low for quite some time.

In Germany, for example, interest rates on public debt up to five years will be negative, and only slightly positive beyond that, producing a weighted average of zero. Clearly, Japan’s near-zero interest-rate environment is no longer unique.

To be sure, the European Central Bank’s large-scale bond-buying program could be suppressing interest rates temporarily, and, once the purchases are halted next year, they will rise again. But investors do not seem to think so. Indeed, Germany’s 30-year bund yield is less than 0.7%, indicating that they expect ultra-low rates for a very long time. And many issuers are extending the maturity structure of their obligations to lock in current rates, which cannot go much lower (but could potentially increase a lot).
