August is supposed to be the corporate bond market’s version of a beach vacation. Desks thin out, deal flow slows down, and everyone quietly counts the days until Labor Day. This year, someone forgot to send the memo.
US investment-grade bond sales hit $130 billion in August, blowing past the $95 billion average the month has posted since 2019. That’s roughly 37% above the seasonal norm, a gap that’s hard to explain away with a few opportunistic deals.
A year of relentless issuance
The August number isn’t an anomaly. It’s part of a broader pattern of corporate America lining up at the debt window with unusual urgency.
Year-to-date investment-grade issuance has reached $1.681 trillion, according to SIFMA data. That figure represents a 26.9% jump compared to the same period last year.
