Simplify MBS ETF (MTBA) is an actively managed exchange-traded fund that seeks total return, consistent with the preservation of capital and prudent investment management, by investing primarily in investment-grade mortgage-backed securities (MBS). The fund focuses on newer-vintage MBS, such as those issued in 2023 and later, which offer higher coupons and yields to maturity compared to the securities in the Bloomberg U.S. MBS Index; it initially targets Federal National Mortgage Association (Fannie Mae) 6.0% coupon bonds obtained through to-be-announced (TBA) forward contracts for enhanced liquidity, operational simplicity, and monthly rolling. MTBA provides exposure to residential and commercial MBS issued by government-sponsored enterprises as well as non-agency MBS, delivering attractive yields relative to comparable U.S. Treasuries with minimal credit risk, and distributes income monthly without lockups, incentive fees, or K-1 tax forms.
Launched on November 6, 2023, and issued by Simplify Asset Management LP, a New York-based firm founded in 2020 that specializes in innovative ETFs incorporating options-based and alternative strategies, MTBA has grown rapidly to over $1.6 billion in net assets as of December 2025, reflecting strong investor demand amid elevated interest rate environments. Recent developments include surpassing $1 billion in assets under management in less than a year by mid-2024, positioning it as Simplify's second-largest ETF behind the Simplify Government Money Market ETF; the firm continues to expand its fixed income lineup with complementary products like the Simplify National Muni Bond ETF in 2024. MTBA trades on the NYSE Arca exchange and targets income-focused investors seeking risk-managed fixed income exposure in a diversified portfolio.
