The S&P 500 was down -30 basis points over the past two weeks. Options trading on the S&P 500 index was strong. The average CCAR bank price rose 260 basis points and the average insurance company price fell -70 basis points. Equity market related RNPD standard deviations (tail risks) generally rose and RNPD skews ticked lower (more negative). These measures do NOT incorporate stress test related information. We intend to follow up with separate analysis of RNPD CCAR reactions.
This time period DOES include market reaction to recent FOMC decisions and guidance. Our standard reports of RNPDs derived from inflation caps and floors show only small changes in the tails. In particular, the reports show the risk neutral probability of deflation changing very little.
We also looked more carefully at risk neutral probabilities in the middle of the distribution. Specifically, we examined changes in risk neutral probabilities at 1%, 2%, and 3% outcomes. The chart below presents the time series of risk neutral probabilities for these outcomes over the subsequent 2 years.
We point out the interesting changes from March 17th to March 19th. The risk neutral probability of a 1% inflation rate over the next two years rose 345 basis points while the probabilities of 2% and 3% inflation fell 120 and 277 basis points respectively. For more information on the methodology for making these estimations see Kitsul and Wright.1
Banks & Insurance Companies
Options trading was also relatively brisk for the insurance companies we follow. Volumes were about average in the broader CCAR universe of banks. RNPD standard deviations and skews were mixed.
Banks with above average and increasing trading volume were BK, KEY, and FITB. Insurance companies with above average and increasing trading volume were HIG, LNC, and MET.
Other Commodity Markets
With the exception of wheat, spot prices in the other commodity markets we follow generally fell over the past two weeks. Corn fell -1.8%, gold fell -1.6%, WTI crude fell -2.0%, and the real estate ETF fell -2.1%. The dollar was stronger. Options trading volumes were light. Consistent with the direction of spot prices, RNPD standard deviations rose slightly.

Large changes in asset values or commodities prices can be associated with significant changes in economic output and price and financial stability. For that reason, policymakers seek to monitor market concerns about extreme movements—so-called tail events—in key asset and commodities markets. The prices of options to buy (“call options”) or sell (“put options”) assets or commodities in the future at specified prices (“strike prices”) provide valuable information about potential tail events. The prices of call and put options with differing strike prices can be used to estimate a probability density function of the payoff of the underlying asset or commodity.
In this report, we use options prices to produce what are known as “risk-neutral probability density functions” (RNPDs) for future asset and commodity values. Interpreting RNPDs can be subtle, because they combine both investors’ expectations of the future price of the traded asset or commodity and the compensation they received for taking on related aggregate economic risks. The changes over time in RNPDs that we show reflect changes to both of these components, and decomposing the change into the constituent parts is not possible without making additional strong assumptions. Nonetheless, we regard the RNPDs shown here as valuable barometers of financial market sensitivity to possible extreme movements in the prices of key assets and commodities.
We welcome feedback on all aspects of the report and material on this web page, which we consider a “work in progress.” Please send comments and suggestions to: email@example.com.
The exhibits contained in this report show density functions at three different points in time, allowing viewers to see how risk-neutral expectations of market participants have evolved over time. Specifically, we think it isuseful to examine the following characteristics within each exhibit and note how they have changed over time:
