The US housing market has been mixed; house prices are rising, but the increase in mortgage rates has posed a challenge to the housing market. Affordability of single-family housing has deteriorated substantially for first time buyers. We saw prices of single-family homes drop modestly, but then quickly followed by seven months of increases this year, largely due to the supply shortage of housing available for sale and rent, plus the pent-up demand for housing among millennials, who are forming new households.

Vacancy rates are at historical lows, and with the strong growth in household formation, a sustained increase in new housing construction is needed. The current increases in construction of single-family housing is not adequate to meet the strong demand. For this reason, we expect a strong support for house prices even if we experience a substantial economic downturn. Our base case for 2024 is a moderate drop in mortgage rates and a stabilisation of prices, as the housing market remains constrained by tight inventory.

We are in favour of securities that are senior in the capital structure and collateralised by seasoned mortgages issued prior to the Global Financial Crisis (GFC) of 2007-2008, while homeowners have a substantial amount of equity in their homes. This provides a strong incentive for homeowners to continue making mortgage payments even in periods of financial stress, to avoid foreclosure. These securities provide significantly more protection against defaults than more recent mortgages in the event of house price declines or recession.

We believe the outlook for these securities is positive for several reasons:

  • Legacy Residential Mortgage-Backed Securities (RMBS) spreads are near the wider end of the historical range
  • The current wide spreads enable the possibility of capital gains on top of the carry. In addition to the strong underlying credit, we believe that one of the major catalysts for spread tightening will be the dwindling supply of new issue RMBS in the current high interest rate environment.

  • Strong underlying mortgage loans in Legacy RMBS
  • Mortgages originated before 2009 have experienced strong home price appreciation (HPA) over the past 15+ years. On average, a mortgage loan originated at the pre-crisis peak in 2007 will have experienced over 50% HPA. The increase in the underlying home asset value improves the performance of the mortgages through lower delinquency levels and higher recovery levels in the case of a default.

  • Defensive positioning even in a recession
  • The senior bonds we focus on are backed by robust mortgages that have substantial home equity and low default risk, as discussed above. The current economic conditions of low unemployment, low household debt and high savings also support the creditworthiness of the securities, even in the event of a recession. Moreover, the average mortgage we invest in has a sufficient value cushion to withstand a potential decline in home prices that exceeds the magnitude of the GFC.
