We show that inflation disagreement, not just expected inflation, has an impact on nominal interest rates. In contrast to expected inflation, which mainly a↵ects the wedge between real and nominal yields, inflation disagreement a↵ects nominal yields predominantly through its impact on the real side of the economy. We show theoretically and empirically that inflation disagreement raises real and nominal yields and their volatilities. Inflation disagreement is positively related to consumers' cross-sectional consumption growth volatility and trading in fixed income securities. Calibrating our model to disagreement, inflation, and yields reproduces the economically significant impact of inflation disagreement on yield curves. , and seminar participants at several conferences and institutions for comments and suggestions. A special thanks goes to Johannes Ruf for many useful discussions about our theoretical results. . 5 We show in the Internet Appendix that inflation disagreement also has an economically and statistically positive e↵ect on the break-even inflation rate and the inflation risk premium. 6 Armantier, de Bruin, Topa, van der Klaauw, and Zafar (2015) show that consumers act on the inflation expectations they report in the MSC. 7 We also show in the Internet Appendix that real and nominal yields and their volatilities are higher when inflation disagreement is high after controlling for disagreement about real GDP growth and earnings. 12 Other papers that empirically explore the role of inflation beliefs on the term structure include Ang, provides a survey of this literature.

An increase in disagreement by one standard deviation for the SPF (0.34%) and the MSC (1.95%) raises the two-year nominal yield by 36% and 51% of its standard deviation (3.42% and 3.63%, respectively).
