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.

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.

With corporate credit spreads at historically narrow levels, investors are not being compensated for the inherent risk. In Richard Bernstein's career, spreads have only been this tight three previous times, each preceding a major credit crisis or market scare (late 1990s, mid-2000s, 2021-22). This suggests a poor entry point for credit.

Despite rising rates, corporate fundamentals are exceptionally strong post-COVID. High EBITDA growth and low leverage mean companies are resilient, justifying the low risk premium (tight spreads) investors are receiving for holding their debt.

With spreads as a percentage of yield at a 25-year low of 15%, investors' returns are dominated by movements in government bond rates, not the premium for taking corporate default risk. This is a hidden vulnerability masked by high all-in yields.

Persistently low high-yield credit spreads, despite global turmoil, don't signal corporate health. This is a structural market shift where the riskiest debt has migrated from public markets to the opaque world of private credit, artificially suppressing spreads and hiding true risk.

While EM sovereign credit spreads are near 20-year historical tights, the asset class remains attractive. This paradox is explained by higher underlying US Treasury rates, which push the 'all-in' yield for investors to compelling levels (above 6%), compensating for the tight spreads and justifying the risk.

Massive government issuance is crowding out private credit and making sovereign bonds inherently riskier. This dynamic is collapsing credit spreads and could lead to a market where high-quality corporate bonds are perceived as safer than government debt, challenging the concept of a 'risk-free' asset.

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.
