American Funds US Government Securities benefits from a highly skilled team that delivers government exposure while nimbly positioning interest rate risk.
Morningstar has enhanced the way we assess excess return opportunity for funds, which is a key component in our Morningstar Medalist Rating calculation. More of this strategy’s Medalist Ratings than usual, therefore, change with this update, even in the absence of changes to pillar ratings or fund costs. As a result, three share classes will reflect these updates.
Experienced leadership and a well-balanced mix of talent enable each manager to focus on their respective areas of strength, helping this stand out among the category’s best. The fund’s principal investment officer, or PIO, Fergus MacDonald, on the fund since 2009, took the reins in January 2015 at the same time the firm added securitized debt expert David Betanzos and rates specialist Ritchie Tuazon comanagers. Capital Group’s multimanager system divides assets among these managers and a four-person analyst-led research portfolio, with MacDonald overseeing overall portfolio exposure as a PIO while giving each sleeve manager and the research portfolio flexibility to invest based on their expertise and focus on what they do best.
The firm announced that securitized debt expert Mr. Pratyoosh will join as a fourth manager on Nov. 1, 2025. This will be his first stint as a portfolio manager, and his fund’s assets will grow gradually, so he can establish his approach within the broader team.
Capital Group’s team-based, risk-aware approach drives the fund’s investments across government sectors, primarily in agency mortgage-backed securities, Treasuries, and Treasury Inflation-Protected Securities while avoiding nonagency MBS and fund leverage. MacDonald integrates insights from the firm’s risk and quantitative solutions team for necessary adjustments and relies on the fixed-income portfolio strategy group for top-down insights that shape the portfolio.
The team’s willingness to manage the portfolio’s duration (a measure of interest rate sensitivity) is another lever that can add value. They maintain duration within 1.0 year of the Bloomberg Government/Mortgage Index, but it has strayed outside this guideline by up to 1.6 years, as it did in mid-2020. However, it doesn't always work out. For example, anticipating a steepening yield curve and lengthening duration out of concern that 2023's March banking panic could spread drove the R6 shares' 2.4% second-quarter drop, which placed last among intermediate-government Morningstar Category peers.
Even with short-term setbacks, the fund’s long-term result stands out. Since February 2015 (MacDonald’s first full month as a PIO), the R6 shares’ 1.7% annualized return through September 2025 ranked in the top decile within the category.
