Loomis, Sayles & Company

Global Fixed Income

For decades, our goal has been to deliver consistent and competitive risk-adjusted returns to our clients.

Security Selection Driven by World-class Research

Everything begins with deep, proprietary fundamental research. We leverage Loomis Sayles’ well-known credit, securitized, macro, sovereign, and quantitative research resources to better understand market opportunities and risks.

Diversified & Disciplined 

To seek to outperform global fixed income benchmarks, we leverage our experience and investment skill to help drive appropriate risk-adjusted positioning in credit, currencies, and yield curves across a broad variety of sectors and countries.


We are patient, disciplined investors who are committed to finding value when markets present it. Drawing upon decades of experience, we are comfortable flexing our risk exposure seeking to outperform when markets offer potential value while minimizing risk to  portfolios during periods of volatility.

Driven by Fundamental Research

We believe fundamental research is a key to unlocking value. But it is just the beginning. Valuation and technical considerations are critical to the overall assessment of any opportunity in our view.

Therefore we leverage our strengths in Loomis Sayles’ extensive, leading research and sector team expertise to identify compelling ideas.

Carry Advantage

We believe relative outperformance can be harvested via a variety of investment strategies that build in yield potential over the benchmark.

Therefore we seek a diversified carry advantage in a variety of spread, treasury and currency markets supported by research depth and breadth.


We believe in dynamically flexing active risks – proactively and defensively – when appropriate, to help capture available risk premiums across global fixed income markets.

Therefore we seek to minimize a portfolio's  outsized drawdown risk of any single investment strategy, while positioning for potential outperformance during volatile markets.

As long-term fundamental investors and fiduciaries, it’s our responsibility to explore all factors that can influence a company’s performance over time.

Dollar Weakens

If the Dollar Weakens, You May Want to Own a Global Bond Strategy

Unlike the past five years, we believe the next five years may see unhedged global benchmarks and active global managers dominate the returns of either dollar-hedged or purely domestic fixed income return indices.
