Key Takeaways
  • • 98% of active Treasury fixed-income managers underperformed their benchmarks over the past 10 years, representing near-universal underperformance in the most conservative fixed-income segment, according to S&P data cited by Apollo Global Management Chief Economist Torsten Slok.
  • • Active public investment-grade credit managers showed 82% underperformance rates, while active public high-yield managers underperformed at 79% over the same decade-long period, indicating structural challenges across the entire public fixed-income spectrum.
  • • Active fixed-income managers underperformed across all strategies without exception over the past 10 years, suggesting that fee structures, market efficiency, and operational constraints systematically prevent active management from delivering alpha in public debt markets.
  • • The data challenges the fundamental value proposition of active fixed-income management, raising questions about fee justification and investor allocation decisions in an environment where passive alternatives consistently deliver benchmark returns minus modest expense ratios.
Summary
Apollo Global Management's Chief Economist Torsten Slok presented performance data highlighting a persistent and widespread underperformance crisis among active fixed-income managers. The analysis, drawing on Standard & Poor's research, reveals that across public fixed-income strategies, active managers have systematically failed to exceed their benchmarks over the past decade.

The underperformance is most severe in Treasury fixed-income funds, where 98% of active managers trailed their benchmarks—a figure that approaches universal failure. This stark outcome suggests that active Treasury management, typically positioned as the safest strategy within the fixed-income universe, cannot overcome fee drag and operational inefficiencies to deliver value. Public investment-grade credit funds showed marginally better results, though still weak: 82% of active managers underperformed. High-yield strategies performed comparatively best among the segments reviewed, yet still registered 79% underperformance, meaning four out of five active high-yield managers failed to beat their indices.

Critically, Slok's presentation notes that underperformance persists uniformly across all public fixed-income strategies without exception. This consistency suggests structural rather than cyclical factors are at work. The combination of rising benchmark efficiency, increasing scale in passive investing, fee compression pressures, and the challenges of identifying alpha in increasingly liquid debt markets creates headwinds that most active managers cannot overcome.

The findings have significant implications for institutional investors, family offices, and hedge funds allocating capital to fixed-income strategies. Investors paying active management fees for Treasury and investment-grade credit exposure face empirical evidence that passive or low-cost approaches historically delivered superior net-of-fee returns. For allocators with active fixed-income mandates, the data underscores the importance of manager selection rigor and raises questions about whether traditional active fixed-income management remains justified as a core institutional holding.
