Fear Over Inflation Hasn't Been This High Since 1999

Jason Goepfert
2021-05-28
Over the past month, the VIX has been highly correlated with 10-year Treasury yields, suggesting inflation fears are driving volatility expectations.

Investors love to latch onto narratives. They're simple, make theoretical sense...and are often completely wrong.

Lately, the narrative has been that stocks have stalled because of fears over inflation. We saw on Wednesday that those fears are valid - when an investor is losing money on earnings after inflation, stocks have often tanked.

This happens to be one of those narratives that has some solid empirical evidence. Over the past month, about when stocks started to go into a holding pattern, the correlation in daily changes between the VIX "fear gauge" and the yield on 10-year Treasury notes skyrocketed to the highest level since 1999.

VIX and 10-year Treasury yield correlation interest rates

Yields drove investors' expectations for volatility throughout much of the 1990s. During that time, when the correlation got to as high a level as it's at now, the S&P showed weak short-term returns but good medium- to long-term ones.

Stat Box

Positive internal momentum has driven the McClellan Summation Index for the French CAC 40 index above +1,000. According to our Backtest Engine, this has happened 26 times in the past 20 years. Short-term future returns were weak, but 3 months later, the CAC was higher 69% of the time.


What else we're looking at

  • Full returns in the S&P 500 after high correlations between the VIX and yields
  • We also go back to the 1960s to search for similar behavior using a synthetic VIX indicator
  • These signals have been more consistent for gold than for stocks or bonds
  • Food prices are skyrocketing - what that means for stocks, sectors, and factors going forward
  • One commodity market, in particular, is setting up into June

Users should conduct their own due diligence and consider their individual circumstances before making any financial decisions. Past performance is not necessarily indicative of future results.

Hypothetical Performance Disclosure: Hypothetical performance results have many inherent limitations, some of which are described below. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown; in fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk of actual trading. for example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all which can adversely affect trading results.
