Is rising investment-grade bond supply pushing up rates and spreads?
Core argument: Total investment grade supply reaching the market this year is around $14 trillion, combining $10 trillion of US government debt to be refinanced over the coming 12 months, a roughly $2 trillion budget deficit, and about $2 trillion of gross corporate bond issuance.
Ten trillion dollars in existing US government debt will need to be refinanced over the coming 12 months. The budget deficit this year is about $2 trillion. Total gross corporate bond issuance in 2026 is likely to be around $2 trillion because of increased supply from hyperscalers. Adding it all up, the total amount of investment grade supply coming to the market this year is around $14 trillion. The bottom line is that the growing supply of investment grade fixed income product is putting upward pressure on rates and credit spreads.
