This Selected Issues paper analyzes Nicaragua’s social security system, which is projected to run out of liquid reserves by 2019, several years earlier than anticipated.

A politically acceptable, pragmatic solution appears within reach. However, the authorities should act quickly to avoid a costly bailout of the system.
