Across global credit markets, focus is shifting from the macro to the micro, and spreads are expected to widen in 2026. “Capex-related issuance across the AI and AI-adjacent ecosystems will take their toll on high-grade spreads, in particular. Plus, M&A and increased leveraged buyout activity will be a factor driving increased issuance across both high-grade and high-yield,” said Stephen Dulake, co-head of Global Fundamental Research at J.P. Morgan.
This dynamic is especially evident in the U.S. high-grade space. “While in recent years we have been more anxious about the macro backdrop disrupting spreads via the channel of lower yields, next year we are forecasting a relatively benign macro environment,” said Nathaniel Rosenbaum, a strategist on the U.S. High-Grade Credit team at J.P. Morgan. “What concerns us more is that high-grade corporates appear to be leaning into this constructive backdrop to increase leverage. With yields 35 bp lower than the starting point for 2025 and 130 bp below the cycle highs, funding costs are no longer as much of an impediment to capex and M&A activity.”
To this end, J.P. Morgan Global Research expects to see moderately wider spreads of 110 bp in U.S. high-grade by year-end 2026. “Even with this widening, high-grade bond spreads will remain quite tight by historical standards. This implies a flat excess return and a total return of 3.0%,” Rosenbaum added.
In Europe, the credit cycle is likely to advance in an environment of cheaper funding rates and reduced policy uncertainty, with some corporates releveraging their balance sheets. Furthermore, global data center construction and European infrastructure spending could require significant amounts of funding from both public and private credit markets.
“Investors in European investment-grade credit markets are suffering from recession fatigue after a string of scares in recent years, making them reluctant to price forward economic risk. Consequently, we are likely to stay in the current tight spread environment until we experience an actual downturn, with our forecast seeing spreads essentially flat at 90 bp,” said Daniel Lamy, head of European Credit Strategy at J.P. Morgan.
For European high-yield, default rates are expected to remain in the 3–4% range for the third consecutive year, but elevated recoveries are limiting credit losses. “We look for the current tight spread regime to continue, with a 2026 forecast of 300 bp, equivalent to a 5.5% total return,” Lamy added.
