The American corporate bond market is witnessing a notable acceleration in high-yield debt issuance. Companies with less robust credit ratings are strategically capitalizing on current favorable conditions, anticipating potential market disruptions stemming from President Donald Trump’s trade tariff adjustments.
High-Yield Market Surge Amidst Uncertainty
This proactive approach is evident in recent figures: May saw an impressive $32 billion in high-yield bond sales, marking the highest volume since October, according to data from JPMorgan. The strong momentum has continued into early June, with sales already surpassing April’s total of $8.6 billion. Bankers and investors widely expect sustained issuance throughout the remainder of the month and into July, driven by robust demand and relatively stable market conditions.
However, this period of stability is precarious. The upcoming expiration of the 90-day pause on President Trump’s “liberation day” tariffs next month threatens to reintroduce significant market uncertainty, echoing the disruptions experienced in early April that nearly halted new leveraged debt deals. David Forgash, a portfolio manager at Pimco, commented on this cyclical pattern, warning of impending “volatility in July.”
Impact on Corporate Borrowing Costs
Corporate borrowing costs, specifically spreads (the additional yield paid by risky borrowers over US government debt), starkly illustrate this sensitivity to policy changes. Following President Trump’s April 2nd tariff announcement, junk bond spreads surged from 3.5 percentage points on April 1st to 4.61 percentage points by April 7th, reaching their highest level since May 2023, as reported by Ice BofA data. This increase reflected investors demanding a higher premium to offset perceived heightened risk. While subsequent progress in trade talks led to a retreat, spreads have not returned to the historically low levels seen in late 2024 and early 2025, which dipped below 3 percentage points.
A leveraged finance banker highlighted the debt market’s general resilience, noting its ability to largely absorb not only the new tariffs but also ongoing geopolitical conflicts in regions like Israel, Palestine, Russia, and Ukraine when evaluating investment opportunities. Nevertheless, the banker cautioned that unexpectedly high tariffs or a new major global conflict could still “throw a spanner in the works,” predicting wider spreads even if not a complete market halt.
Strength in Investment-Grade Market
The robust demand isn’t limited solely to high-yield bonds. Strong interest also extends to highly-rated corporate debt. Strategists at Bank of America project June investment-grade bond sales to reach between $110 billion and $120 billion, potentially making it the strongest June volume for this segment since 2021. Kyle Stegemeyer, head of investment grade debt capital markets and syndicate at US Bancorp, affirmed the prevailing issuer sentiment: “If there’s an open window and the backdrop’s attractive, why wait it out until closer to maturity?” This underscores a strategic imperative for corporations to issue debt during periods of market calm before potential future volatility.
