We analyze the so-called deflationary equilibrium of the New Keynesian model with an interest rate lower bound when the future course of the economy is uncertain. We find that, in the deflationary equilibrium, the rate of inflation is higher at the risky steady state---which takes uncertainty into account---than at the deterministic steady state---which abstracts from uncertainty. The rate of inflation at the risky steady state can be positive if the central bank's inflation target is positive.
