Investors are increasingly shifting from equity portfolios to investment-grade corporate bonds, driven by worries that stock market valuations are nearing a peak. This de-risking trend has led to strong demand for corporate debt, pushing corporate borrowing costs to their tightest levels since 1998. The average investment-grade bond spread stood at 80 basis points, just three basis points away from its 1998 low of 77 bps, and temporarily hit 78 bps in late July, one basis point shy of that record low. This surge in demand has allowed companies to issue new debt with little to no new-issue premium, as order books for nearly $51 billion of corporate bonds issued in July were oversubscribed by more than four times.
The recovery in credit spreads comes after a sharp widening on April 2, or 'Liberation Day,' when President Donald Trump announced trade tariffs, creating unease about corporate fundamentals. Optimism, confirmed by recent corporate earnings, suggests high-rated companies have improved their balance sheets and are prepared for potential economic impacts from tariffs or trade wars. Additionally, the Federal Reserve's sustained high-interest rates, due to persistent inflation, have kept corporate bond yields attractive, drawing demand from yield-focused investors like insurance companies and pension funds. Since the beginning of 2025, over $180 billion has flowed into taxable bond funds and ETFs, while approximately $10 billion has exited domestic equity funds and ETFs.
Despite the current strong demand and tight spreads, not all analysts are convinced the rally will continue. While some, like Michael Levitin of MidOcean Partners, expect tighter spreads, others anticipate a reversal. CreditSights' global head of strategy, Winnie Cisar, forecasts investment-grade credit spreads to widen to 110 bps by year-end, still within the long-term median of 130 bps. JPMorgan analysts expect high-yield bond spreads to widen to 500 bps, up from their previous forecast of 380 bps. Some asset managers, including Gershon Distenfeld of AllianceBernstein, have already begun cutting credit exposure, arguing that spreads are too tight to justify the risk of further investment. This mixed outlook suggests potential volatility in corporate bond spreads in the coming months.
