What this means for investors
Investors may be interested in bond funds in early 2026 to take advantage of the possibility of further rate cuts by the Federal Reserve. The Fed cut rates twice last year, and it’s widely expected that rates will come down further. This makes high-yielding, investment-grade bonds more attractive right now.
Both BSV and IGSB are high-quality funds focusing on investment-grade bonds. While BSV has a lower expense ratio, the 0.01 percentage point difference is not enough to worry about, considering IGSB’s higher dividend yield.
It’s hard not to like IGSB right now. It pays a yield of over 4% at the moment, which is more attractive given its larger bond portfolio and history of beating BSV’s returns.
However, if safety is your goal, BSV’s nearly 70% allocation to U.S. government bonds might be the better choice. Still, both funds had similar drawdowns when interest rates rose in 2022. IGSB has proven to be a quality bond fund for income investors, given its superior returns with relatively low volatility.
