Treasury Market Flashes New Warning As Real Yields Go Negative

 | Feb 13, 2020 07:24AM ET

It happened before, in 2012-2013, but the US economy muddled through a soft patch. Is it different this time? It’s a question worth pondering as the global economy struggles to model the spreading coronavirus that’s weighing on China and, increasingly, reverberating in economies around the world. The European Commission today, for example, advises that coronavirus is a “key downside risk” for the bloc’s economy.

The Treasury market appears to be pricing in this risk. Notably, real yields for key maturities in inflation-indexed government bonds (TIPS) have slipped into negative terrain lately. From a big-picture perspective, real yields (compensation for holding bonds after adjusting for inflation) tend to be positive and rising in periods when the economic outlook is positive and expansion is accelerating. By contrast, negative yields imply the opposite.

The real yield for TIPS, however, is complicated by the fact that the Treasury market overall attracts global demand and so it’s unclear how reliable US government bond rates are these days for assessing the outlook for the American economy. There’s also a debate about how useful TIPS are for macro analysis since this corner of the Treasury market is considerably less liquid vs. its nominal counterpart for government bonds.

What is clear is that TIPS yields have been sliding for more than a year and has recently dipped below zero for key maturities. As of yesterday’s close (Feb. 12), the 5- and 10-year TIPS maturities were yielding -0.19% and -0.04%, respectively, according to Treasury.gov. The 5-year yield has been negative throughout 2020 to date; the 10-year maturity is a relative newcomer to the sub-zero pricing, but so far in February it’s been a consistent trend.

It comes as no surprise to learn that the 10-year TIPS rate is plumbing depths below zero. As the chart below reminds, the slide for this maturity’s real yield has been unfolding for well over a year. If trend is fate for the near-term, the current environment has been foreordained for months.
