The R-bond is a Treasury-issued bond that has been proposed as a suitable investment and cornerstone for the proposed auto-IRA program. The R-bond or retirement bond is to be a low-risk, stable investment that would provide secure returns. R-bonds would help get the mandatory auto –IRAs off the starting block until more substantial balances are built in participant accounts. As many of the account holders of auto-IRAs would be workers who have never had substantial retirement savings, a conservative investment such as the R-bond would give them peace of mind. At the moment, details of the R-bond have yet to be disclosed.
