The Long View: Sara Devereux - Bonds Are Still Ballast

Key Concepts

• Vanguard’s Strategic Shift: A move towards increased active management (“Active Edge”) alongside continued strength in index funds and ETF expansion, aiming to lower cost and complexity across all fixed income markets.
• Active Edge Philosophy: A three-pillar approach (People, Process, Performance) emphasizing collaboration, repeatable strategies, and technology to deliver consistent, low-cost active management.
• ETF Growth & Vanguard’s Position: The rapid expansion of the ETF market, particularly in fixed income, presents a significant opportunity for Vanguard due to its established active team and ETF infrastructure.
• Technological Investment: Heavy investment in technology to enhance insights, accelerate decision-making, and optimize execution within fixed income operations.
• Market Outlook (2026): Anticipation of a positive year for fixed income driven by income, with key themes including shifting policy, emerging credit cracks, and the impact of AI capex.
• Market Technicals: Heavy supply driven by AI capex alongside robust demand, leading to a shift in investor preference towards longer-duration bonds.

Vanguard’s Fixed Income Evolution & Strategy

Over the past five years, Vanguard’s fixed income group has navigated significant market volatility while focusing on its mission to provide investors with the best chance of investment success. A core strategic shift has been a “lean towards active management,” building capabilities alongside its established index funds and a substantial expansion into Exchange Traded Funds (ETFs). This vision aims to bring the “Vanguard effect” – lowering cost and complexity – to all of fixed income. In the past year alone, 23 new products, primarily ETFs, were launched, bringing Assets Under Management (AUM) to $2.88 trillion (up from $1.9 trillion). Despite these changes, a “laser focus on clients and performance” remains, evidenced by low costs (98% of active funds in the lowest decile of their category) and strong performance (85% of bond funds outperforming peers over a 10-year period), with $350 million returned to clients last year through expense ratio cuts.

Active Fixed Income Philosophy – “Active Edge”

Addressing Jack Bogle’s historical “virtual indexing” approach, Vanguard now believes it can deliver low-cost active management through scale, skill, and technology. Their active approach, termed “Active Edge,” centers on “consistency over the long term” and is built on three pillars: People, Process, and Performance. The team emphasizes collaboration over “star managers,” with complete alignment between portfolio managers and clients (PM success measured by alpha, not AUM). Technology supports this team, scaling their impact. The active process is rigorous, combining top-down and bottom-up analysis with risk management, focusing on “repeatable and reliable strategies” with high information ratios. A key tool is an “alpha waterfall,” prioritizing strategies with the highest information ratio, such as security selection and credit research. Valuation discipline is also crucial, allowing for patience and opportunistic deployment of capital. The team prioritizes “being true to label” to build client trust.

The Rise of ETFs & Vanguard’s Position

The ETF market has grown rapidly (from $2 trillion to $13 trillion in a decade), with fixed income representing approximately 20% of that total. Significant room for growth remains, particularly in active fixed income ETFs, which are gaining traction (40% of fixed income ETF flows in 2025 went to active ETFs). Vanguard is uniquely positioned to excel in this space due to its established active fixed income team (40+ years of experience) and its strong ETF infrastructure (launched its first fixed income ETF in 2007, now the largest with over $140 billion AUM). Vanguard’s product development prioritizes meeting diverse client needs and ensuring enduring investment merit, with caution regarding launching ETFs in illiquid segments.

Technology & Innovation

Vanguard is heavily investing in technology across its fixed income operations, focusing on three strategic pillars: Enhanced Insights, Faster Decisions, and Optimized Execution. This includes leveraging big data, AI/ML for relative value signals and earnings analysis, advanced optimization engines, and tools to streamline dealer quotes and trading. The goal is to augment portfolio managers’ capabilities, not replace them, enabling them to focus on higher-value intellectual activities. An example is reducing ETF basket creation time from two hours to 10-15 minutes, and experimentation with quantum computing.

Market Outlook & Key Themes (2026)

Vanguard anticipates another good year for fixed income, driven by income rather than price appreciation, with yields expected to remain rangebound. Key themes include: Shifting Policy Crosswinds (2025 headwinds offset by 2026 tailwinds from infrastructure, deregulation, and Fed cuts), Emerging Cracks in Credit Markets (tight spreads requiring diligence, with private credit as a potential leading indicator), and AI Capex (a major macro force increasingly funded by debt issuance, potentially creating technical headwinds).

Market Technicals & Investor Behavior

The high yield market has shifted in composition, with the double-B segment now comprising 50% of the index (compared to 33% in 2007) and triple-C bonds decreasing to 11% (from 22% in 2007). This change accounts for approximately 50 basis points of the current spread differential in the high yield market. AI capital expenditure is adding approximately 50 basis points to GDP forecasts and is increasingly funded through debt issuance, particularly by hyperscalers, rising from $20 billion in 2024 to $100 billion in late 2025, with expectations of nearly $400 billion in 2026 – representing around 15% of total Investment Grade (IG) issuance. This increased supply is expected to create temporary pressure on spreads (“technical”), but the high credit quality of these issuers presents a potential buying opportunity.

2026 is anticipated to be characterized by both heavy supply and heavy demand. Industry-wide fixed income inflows were over $1 trillion in both 2023 and 2025. In 2023, 80% of these inflows went into money market funds, while in 2025, the split was 50/50. At Vanguard, the allocation was even more pronounced, with a 25/75 split between money market funds and longer-duration fixed income. This trend is expected to continue as the Federal Reserve cuts rates and the term premium increases, making longer-duration bonds more attractive. Investors are increasingly allocating to longer-duration bonds, driven by the flattening and then steepening of the yield curve and declining cash rates.

Conclusion

Vanguard is strategically positioning itself to capitalize on the evolving fixed income landscape through a commitment to low-cost active management, technological innovation, and a client-centric approach. The firm anticipates a favorable environment for fixed income in 2026, driven by income and influenced by key themes such as shifting policy, credit market dynamics, and the substantial impact of AI-related capital expenditure. The combination of heavy supply and robust demand, coupled with a shift towards longer-duration bonds, suggests a dynamic and potentially rewarding environment for fixed income investors.
