Henry Dyer and Tomas Jankauskas argue in Liberty Street Economics that rate surprises shift equity risk premia

The post was published on August 12, 2026. Henry Dyer and Tomas Jankauskas examine how Federal Reserve monetary policy surprises relate to equity risk premia and expected dividend growth across different maturities. Using a model that estimates these components separately, they report that negative surprises are associated with a 25-basis-point increase in the average risk premium, while positive surprises show similar movements. The estimated effects of both are small and statistically insignificant. Expected dividend growth appears to move with dovish surprises: it falls across maturities, with the largest decrease at the shortest maturities. The authors suggest that large rate cuts may signal economic distress and weaker growth prospects; they suggest rate hikes may reflect strong demand or inflationary pressures, which do not necessarily reduce nominal growth. Their conclusion is that large interest rate shocks induce a parallel increase in equity risk premia, while only negative monetary policy surprises lower dividend growth expectations. The estimates use data from 1988–2020; whether these relationships persist beyond that sample remains unknown.

summary — uncertain: The core terms are never explained for a non-specialist: equity risk premia, monetary policy surprises, dovish and hawkish, FOMC, and maturities across the term structure. Only basis point is defined. The reading also never says why the finding matters. The title says surprises shift equity risk premia, yet the authors call the effects small and statistically insignificant. The source's conclusion does use that wording, but the title should carry the caveat. Smallest repair: add plain-language glosses for these terms, or term-library entries, and qualify the title.

The effects of both negative and positive surprises are not very large in economic magnitude and are statistically insignificant

August 12, 2026 Does the Equity Term Structure Respond to Monetary Policy Shocks?

support — pass: The source supports each reported claim: the 25-basis-point rise after negative surprises, similar moves after positive surprises, the statistical insignificance, and dividend growth co-moving only with dovish surprises (over 50 bp at short maturities, 20 bp at long). The authors' interpretations are framed as suggestions, as in the source. The 1988–2020 sample and the open question about persistence are grounded in the text.

There is an over 50-basis-point drop for the shortest maturities and a 20-basis-point decrease for the longest maturities.

media — pass: No media was selected and no verified candidates were supplied, so there is nothing to misidentify.
