Assumes unchanged yield curve and 3 Mo funding rate.
Carry and rolldown decompose the expected return of holding a bond over a given horizon assuming the yield curve does not change. Carry is the income earned from holding a higher-yielding bond funded at the short-term rate — for the 10 Yr Treasury over a 1 Yr horizon, this reflects the spread between the 10 Yr par yield and the 3 Mo funding rate. Rolldown is the capital gain (or loss) from the bond "rolling down" the curve as its remaining maturity shortens and it reprices at a lower yield point on an upward-sloping curve. A total return of 109.1 bps means an investor would earn approximately that annualized return in excess of the funding rate if curves remain unchanged. Positive total return suggests the position is self-financing; negative total return indicates the investor pays to maintain the position, betting on a rate decline or other catalyst.
The 10 Yr currently offers positive carry of 73.0 bps over the 1 Yr horizon, meaning the bond yields more than the short-term funding rate and the position generates net interest income on its own. Rolldown adds 36.1 bps, reflecting an upward-sloping curve in the 10 Yr region. As the bond ages and its remaining maturity shortens, it reprices at a lower yield on the curve, generating a capital gain on top of carry income.
