Non-agency MBS

Definition

Non-agency mortgage-backed securities (MBS) are bonds backed by mortgages that are not guaranteed by government-sponsored entities like Fannie Mae or Freddie Mac. These securities are issued by private institutions and typically carry a higher yield compared to agency MBS due to the increased risk associated with them. They play an important role in the financial markets by allowing investors to gain exposure to real estate assets without directly owning the properties.

Review Questions

• How do non-agency MBS differ from agency MBS in terms of risk and return profiles?
  • Non-agency MBS differ from agency MBS primarily in their risk and return profiles due to the lack of government backing. Non-agency MBS are backed by private institutions and consist of loans that may not meet agency standards, leading to a higher default risk. Consequently, investors expect higher yields from non-agency MBS as compensation for this increased risk, making them more attractive during favorable market conditions but potentially more volatile in economic downturns.
• What are some key factors investors should consider when analyzing non-agency MBS?
  • When analyzing non-agency MBS, investors should consider several key factors including the credit quality of the underlying mortgage loans, the structure of the security, and potential prepayment risks. Understanding borrower profiles and loan performance history is critical for assessing credit risk. Additionally, investors must evaluate how different tranches within collateralized mortgage obligations (CMOs) may affect returns and risks associated with non-agency MBS.
• Evaluate the impact of economic conditions on the performance of non-agency MBS and discuss how this influences investor strategy.
  • Economic conditions significantly influence the performance of non-agency MBS, as downturns often lead to increased mortgage defaults and delinquencies. This heightened risk impacts cash flows and overall returns on these securities. Investors must adapt their strategies by conducting rigorous credit analysis and diversifying their portfolios to mitigate potential losses. In stronger economic times, however, non-agency MBS can offer attractive yields and opportunities for capital appreciation, prompting investors to reassess their exposure based on prevailing market trends.
