What the 40% Bond Allocation Should Do

If “fixed income is broken,” what are investors actually missing—and how should they rebuild the 40% to protect and compound through drawdowns? In this episode, I speak with Thomas E. Swaney II, former Chief Investment Officer of Global Fixed Income at Northern Trust Asset Management, who oversaw more than $600 billion across global fixed income. Thomas explains why traditional bond allocations fail when it matters most, how to separate duration from credit risk, and how to use notional leverage to target true diversification without sacrificing liquidity. We explore the structural flaws in 60/40, how to design a fixed income portfolio that actually offsets equity drawdowns, and why the future of bond investing depends on better risk budgeting—not higher yield.

Highlights:

• Fixed Income Is Broken: Why most bond portfolios don’t diversify when equities fall
• Rebuilding the 40%: Duration vs. credit and managing correlation through regimes
• Notional Leverage: Using treasury futures and IG CDX to build volatility with quality
• Risk Parity Framework: Allocating by contribution to risk, not nominal dollars
• Rebalancing Alpha: Liquidity and negative correlation as the real edge
• Curve Positioning: Why the belly of the curve often outperforms the long end
• Convexity Mismatch: Public vs. private assets and the lagged rebound effect
• Inflation Regimes: How correlation flips and when to incorporate TIPS
• Leadership & Culture: Lessons from Ellington and Northern Trust on process and debate
• The Next Decade: Bonds are relevant again—if built for resilience
