Real Return Bond yields

Changed on

Real Return Bond (RRB) yield (BD.CDN.RRB.DQ.YLD) and the long-term nominal benchmark (BD.CDN.LONG.DQ.YLD). The spread between the two approximates break-even inflation expectations at the long end of the curve.

RRB issuance was discontinued in November 2022 for new primary-market auctions; secondary-market yields continue to be published.
