We show that the supply of life annuities in the U.S. is constrained by interest rate risk. We identify this effect using annuity prices offered by U.S. life insurers from 1989 to 2019 and exogenous variations in contract-level regulatory capital requirements. The cost of interest rate risk management accounts for at least half of the average life annuity markups or eight per- centage points. The contribution of interest rate risk to annuity markups sharply increased after the great financial crisis, suggesting new retirees' opportunities to transfer their longevity risk are unlikely to improve in a persistently low interest rate environment.
