I remain bullish about the iShares MBS ETF's prospects, foreseeing mid-to-high single-digit returns for 2026. MBB might benefit from favorable duration dynamics, high coupon rates, and anticipated institutional buying support. Risks include a potential mortgage spread re-rating and a concave risk-return distribution.
When bond investors chase yield, they often overlook the engine that drives total returns: price appreciation from interest rate movements.
High mortgage rates remain the primary obstacle to the American Dream; with the current 30-year fixed rate at 6.20%, the income required to buy a house has nearly doubled since 2019. Despite recent spikes, mortgage rates are expected to return to their long-term downward trend as the economy normalizes and the Fed continues to adjust short-term rates. Safety of Agency MBS: Both NLY and MBB invest in securities where the principal is guaranteed by Fannie Mae and Freddie Mac, offering minimal credit risk even if borrowers default.
The iShares MBS ETF offers agency mortgage-backed securities exposure with a $39B AUM, no credit risk, and a 5.4-year duration. MBB's low volatility and 4.15% SEC yield make it a stable, ‘boring' instrument, but it becomes compelling when rates are poised to fall. With a potential new Fed Chair in 2026 likely to cut rates aggressively, MBB is positioned for outsized returns in a declining rate environment.
MBB offers higher duration exposure, attractive in a rate-cutting environment, but prepayment risks require extra yield compensation versus Treasuries. Crudely, around two-thirds of MBB's holdings are unlikely to be refinanced with a likely rate cutting path, so the current yield fairly compensates for mitigated prepayment risk, but not more. While the call premium between the Treasuries and mortgage rates has historically been lower, we think that is also well priced in the current, somewhat uncertain environment.
The iShares MBS ETF's key variables suggest that it could be a U.S. treasury diversifier. The vehicle invests in secondary agency RMBS, which hold enough credibility to act as collateral for repo lenders. Moreover, underlying guarantors have the same credit ratings as the U.S. MBB ETF's standard deviation and max drawdown ratios are lower than those of an intermediate-term treasury vehicle called IEF ETF.
MBB is the largest MBS ETF in the market. Its 4.0% yield is slightly above-average, returns since inception below-average. It compares unfavorably to its peers in several key ways.
