In 1935, amidst massive economic uncertainty following the Great Depression, a new AA-rated corporate bond yielded just 70 basis points over Treasurys. This historical precedent, nearly identical to today's spreads, shows that low credit spreads are not necessarily a sign of complacency and can persist even if economic conditions worsen, challenging typical risk-pricing assumptions.
The primary threat to the high-yield market isn't a wave of corporate defaults, but rather a reversion of the compressed risk premium that investors demand. This premium has been historically low, and a return to normal levels presents a significant valuation risk, even if fundamentals remain stable.
The credit market appears healthy based on tight average spreads, but this is misleading. A strong top 90% of the market pulls the average down, while the bottom 10% faces severe distress, with loans "dropping like a stone." The weight of prolonged high borrowing costs is creating a clear divide between healthy and struggling companies.
While default risk exists, the more pressing problem for credit investors is a severe supply-demand imbalance. A shortage of new M&A and corporate issuance, combined with massive sideline capital (e.g., $8T in money markets), keeps spreads historically tight and makes finding attractive opportunities the main challenge.
History shows that markets with a CAPE ratio above 30 combined with high-yield credit spreads below 3% precede periods of poor returns. This rare and dangerous combination was previously seen in 2000, 2007, and 2019, suggesting extreme caution is warranted for U.S. equities.
The expected wave of M&A and LBOs has not materialized, leaving the deal pipeline thin. This lack of new debt supply provides a strong supportive backdrop for credit spreads, allowing the market to absorb geopolitical volatility more easily than fundamentals would otherwise suggest.
Judging the credit market by its overall index spread is misleading. The significant gap between the tightest and widest spreads (high dispersion) reveals that the market is rewarding quality and punishing uncertainty. This makes individual credit selection far more important than a top-down market view.
Despite forecasting a massive surge in bond issuance to fund AI and M&A, Morgan Stanley expects credit spreads to widen only modestly. This is because high-quality, highly-rated companies will lead the issuance, and continued demand from yield-focused buyers should help anchor spreads.
In a market where spreads are tight and technicals prevent sustained sell-offs, making large directional bets is a poor strategy. The best approach is to stay close to benchmarks in terms of overall risk and allocate the risk budget to identifying specific winners and losers through deep, fundamental credit analysis.
Enormous government borrowing is absorbing so much capital that it's crowding out corporate debt issuance, particularly for smaller businesses. This lack of new corporate supply leads to ironically tight credit spreads for large borrowers. This dynamic mirrors the intense concentration seen in public equity markets.
The gap between high-yield and investment-grade credit is shrinking. The average high-yield rating is now BB, while investment-grade is BBB—the closest they've ever been. This fundamental convergence in quality helps explain why the yield spread between the two asset classes is also at a historical low, reflecting market efficiency rather than just irrational exuberance.
