Spreads on investment-grade (IG) corporate bonds are currently trading below 85 basis points, placing them near the 19th percentile of the past five years, according to market analysis. At these levels, valuations appear stretched, leaving investors with limited potential upside while increasing the risk of spreads widening in the near future.
Historical data dating back to 1998 suggests that when spreads begin from levels below 85 basis points, the likelihood of further tightening is relatively low. Instead, the probability of spreads widening over a one-year period is estimated at around 84%. Analysts say spreads would need to widen to the 110–135 basis points range before offering a more balanced risk-return profile, where the probability of widening falls closer to 47%.
Despite these signals, many investors continue to pursue higher yields in a low-spread environment, accepting lower compensation for credit risk. Market experts warn that this approach may expose portfolios to greater downside risk if spreads begin to widen.
In response, some investors are adopting a more cautious strategy by shifting toward higher-quality assets. While investment-grade corporate bonds are generally considered safe due to their low default risk, analysts note that they can still face mark-to-market losses if spreads widen, particularly for bonds with longer maturities.
Research suggests that structured credit investments may offer an alternative in such conditions. Compared with traditional corporate bonds, certain structured credit strategies typically have lower spread duration, meaning their prices are less sensitive to changes in credit spreads. This characteristic can help reduce price volatility during periods of market stress.
Some strategies also focus on investing in the senior layers of the capital structure, which generally carry lower credit risk. By avoiding riskier segments and securities with negatively convex profiles, investors may be able to reduce downside exposure during volatile market cycles.
Since 2016, structured credit portfolios following this approach have delivered an average spread advantage of around 42 basis points over investment-grade bonds, while maintaining significantly shorter duration. Analysts say this combination has helped produce more stable returns and stronger risk-adjusted performance across credit market cycles.
