In this paper indexation is considered as an insurance contract against the risk of unanticipated inflation. Expressions for the supply of and demand for indexation are derived. The desired degree of indexation of any item in a portfolio turns out to depend, among other things, on the degree of indexation on other items, on the covariances between inflation and nominal returns on all items in the portfolio, on expected inflation, and on the marginal risk premium for the inflation risk. These results are compared with those reached by the macroeconomic literature on indexation. The consequences of exogenous changes in the supply of indexed assets are analysed.
