Barclays Says Credit Liquidity Premium Gone as E-Trading Thrives

Barclays Plc reports that the illiquidity premium on investment-grade bonds has effectively vanished, dropping to near zero in July from an average of 11 basis points between 2018 and 2024. This significant shift, attributed to the boom in electronic and portfolio trading, fundamentally alters the compensation structure for owning tougher-to-sell credit, excluding periods of high market volatility.

Analysis

A research note from Barclays Plc indicates a significant structural shift in the investment-grade credit market, where the illiquidity premium has effectively been eliminated. According to analysts Zornitsa Todorova and Andrea Diaz Lafuente, this premium, which compensates investors for holding tougher-to-sell bonds, fell to nearly zero in July. This represents a stark decline from an average of 11 basis points between 2018 and 2024 and 35 basis points in the 2011-2017 period. The primary driver of this compression is the proliferation of electronic and portfolio trading, which has enhanced market liquidity and price discovery. This development fundamentally alters the return profile for investment-grade credit, suggesting that technological advancements have arbitraged away a traditional source of alpha. It is critical to note, however, that this observation excludes periods of heightened market volatility, implying that the illiquidity premium could re-emerge rapidly during market stress.

Key Decisions for Investors

• Investors should re-evaluate strategies that rely on capturing an illiquidity premium in investment-grade credit, as this source of excess return has largely disappeared due to improved market efficiency.
• Portfolio managers may need to place a greater emphasis on fundamental credit selection and relative value analysis to generate alpha, rather than relying on compensation for holding less liquid assets.
• Caution is warranted as the analysis excludes high-volatility periods; investors should be prepared for the potential reappearance of liquidity premiums and associated price drawdowns during market dislocations.
• Consider the technological capabilities of trading platforms, as access to advanced electronic and portfolio trading systems is now a critical factor for efficient execution and competitive pricing in the corporate bond market.
