Blazing high-grade issuance for a holiday-shortened week back from Labor Day — a historically explosive period for pent-up dealmaking after summer lulls — totaled $57 billion Tuesday and Wednesday alone across 30 offerings, raising the possibility of a fourth straight monthly record. The totals in June ($184 billion), July ($137 billion), and August ($151 billion) were the highest ever for those months, per LCD.
Syndicate desks are suggesting September supply of well over $200 billion. That would supplant last September's unprecedented $189 billion output, which included the first major shot fired in the ongoing AI debt barrage, via a blockbuster $18 billion print for Oracle.
A lot has changed for the funding landscape since then, however. Oracle priced 5.95% notes due 2055 as part of that year-ago package, and investors initially chased spreads tighter. Not so now: the notes yielded roughly 7.875% on Sept. 10 on dollar prices south of 79% of par, and investors commanded spreads of T+245 to take on the paper, nearly doubling the T+125 pricing level.
AI debt remains a relative outlier for spreads, however. The latest T+78 spread (to worst) for Morningstar's IG index, while up from T+69 at the lows this year, is just one basis point wider year to year, and firm versus the annual averages in 2025 (T+82) and 2024 (T+87.5).
