Non-Diversification: Free Stock Risk Without The Reward

Let me be quick to acknowledge that yield curve inversion can have considerable lag time before a recession. And for that matter, the U.S. Treasury bond curve can invert long before a stock market bear.

For instance, 10-year yields fell below two-year yields in February of 2006. That was approximately 22 months before the recession officially hit in December of 2007. What’s more, between 2/2006-10/2007, the S&P 500 managed to climb more than 20%.

There’s more. The 1990s Treasury bond curve first inverted in June of 1998. The recession did not begin until March of 2001. And we already know that the S&P 500 tacked on roughly 40% from 6/08 to the 3/2000 peak; the index picked up closer to 12% if one waited until the official recession inception.

Nevertheless, investors should not be quick to dismiss the message of flattening yield curves that invert. Specifically, when short-term interest rates exceed long-term ones, financial markets perceive weakness for the economy going forward. In a sense, financial markets may be telling committee members at the Federal Reserve that they’re in danger of making an egregious policy error.
