I construct an overlapping-generations model of money with Epstein and Zin (1989) preferences and study how aggregate output uncertainty affects the optimal rate of inflation. When money only serves as savings instruments, I find that the optimality of Friedman Rule breaks up only if agents prefer late resolution of uncertainty. However, if an additional role of money as a medium of exchange is introduced, then the Friedman Rule becomes generally suboptimal regardless of agents' preferences for the timing of uncertainty resolution. The aggregate output uncertainty, nevertheless, crucially determines the level of optimal inflation rate in this case.
