Treasury Yields: A Long-Term Perspective

 | Aug 13, 2017 03:11AM ET

Let's have a look at a long-term perspective on Treasury yields as of today's close. The chart below shows the 10-Year Constant Maturity yield since 1962 along with the Federal Funds Rate (FFR) and inflation. The range has been astonishing. The stagflation that set in after the 1973 Oil Embargo was finally ended after Paul Volcker raised the FFR to 20.06%.

Last year was a remarkable one for yields. The 10-Year note hit its historic closing low of 1.37% in July and then rose 123 BPs to its 2016 closing high of 2.60% in mid-December. The yield on the 10-year note to date has dropped to 2.25% as of today's close.

Now let's overlay the S&P 500 to see historical pattern of equities versus treasuries. This is a nominal chart, which significantly distorted the real value of both yields and equity prices.

Here's the same chart with the S&P 500 and 10-year yields adjusted for inflation using the Consumer Price Index. The impact of stagflation becomes much clearer. We can better understand the severity of the decline in equities from the mid-1960s to the bottom in 1982. And we can also see why high yields can be deceptive in periods of double-digit inflation.
