When low interest rates are prevalent throughout the economy, there is usually an increased demand for mortgage loans. This increase generally results in more asset-based securities, which can increase the pool of high-quality assets in this investment category.
Fixed-income investors looking for higher yields than U.S. Treasuries might consider investing in an exchange-traded fund (ETF) that focuses on mortgage-backed securities (MBS).
Discover some of the most popular MBS ETFs that investors might turn to when rates are low.
Key Takeaways
- Agency mortgage-backed securities (MBS) are issued by government-sponsored enterprises such as Fannie Mae, Freddie Mac, and Ginnie Mae.
- An MBS is a pass-through security because an intermediary passes through payments from the issuer to the security holder.
- Essentially, an investor with exposure to an MBS receives a stream of payments from homeowners paying interest on their mortgages.
- ETFs that focus on mortgage-backed securities provide a convenient way for fixed-income investors to get exposure to this market.
Mortgage Backed Securities ETFs
Mortgage-backed securities are created by restructuring a collection of illiquid mortgage loans into a single, tradeable security. The securities are rated by the quality of the credit attached to the underlying pool of loans. Coupons are assigned based on the loan ratings, with lower-rated securities having higher coupon rates to attract investors.
Agency mortgage-backed securities are issued by government-sponsored enterprises (GSE) such as Fannie Mae, Freddie Mac, and Ginnie Mae. They are referred to as pass-through securities because an intermediary passes through payments from the issuer to the security holders.
MBS exchange-traded funds are bundles of mortgage-backed securities that trade on an exchange. These funds allow investors to gain exposure to the MBS market without worrying about the difficulties of buying and selling illiquid assets.
Here are the three most popular MBS ETFs to consider.
Mortgage-backed securities were less regulated in the past and contributed to the Great Financial Crisis. They have since become subject to more regulation, but they are still considered risky for retail investors.
