Credit spreads—the extra yield investors demand for holding corporate bonds over U.S. Treasuries—have tightened to around 75 basis points, levels not seen since 1998. This metric serves as a key indicator of market confidence, with tighter spreads suggesting investors perceive minimal default risk from high-quality corporate borrowers.
What makes these tight spreads particularly noteworthy is the unprecedented supply dynamics at play. Companies raised more than $1.7 trillion in investment grade debt last year, and forecasts suggest the total issuance in 2026 could reach $2.1 trillion. Traditional market economics would predict that increased supply should push prices down and lead to higher yields. However, credit spreads remain low.
The AI infrastructure boom is driving much of the issuance wave, with major tech companies requiring trillions in capital for data centers and computing infrastructure. TD Securities estimates $500 billion in AI-related issuance this year alone. Despite the large issuances, many of these major tech companies, like Meta and Google, have strong balance sheets and consistent cash flows that are easing investors’ concerns over the volume of issuances.
The critical question is whether current spread levels withstand this unprecedented issuance wave? Many strategists believe spreads have limited room to tighten further and may begin widening as supply continues at this pace.

The ICE BofA Option-Adjusted Spreads (OASs) are the calculated spreads between a computed OAS index of all bonds in a given rating category and a spot Treasury curve. An OAS index is constructed using each constituent bond's OAS, weighted by market capitalization. The Corporate Master OAS uses an index of bonds that are considered investment grade (those rated BBB or better). When the last calendar day of the month takes place on the weekend, weekend observations will occur as a result of month ending accrued interest adjustments. Investors cannot invest directly in indexes. The performance of any index is not indicative of the performance of any investment and does not take into account the effects of inflation and the fees and expenses associated with investing.
