Global Credit: Energy Shocks, AI Borrowing, and Signs of Stress | EP 214
April 23, 2026

In this episode, Brian Carney, lead portfolio manager of the Mawer Global Credit Opportunities Strategy, examines a fixed income backdrop reshaped by geopolitical escalation, an energy shock, and sharply changing interest-rate expectations. He explains why higher benchmark yields and modestly wider spreads still leave many parts of credit looking expensive, where Mawer is finding more selective value through bottom-up research, and why the strategy remains tilted toward shorter-duration, higher-quality credit. The conversation also explores AI-related bond issuance from hyperscalers, signs of strain in leveraged finance and private credit, and what a more fragile lending environment could mean for investors.

Highlights:

•    How geopolitical escalation and higher oil prices have pushed inflation concerns back to the forefront and reshaped rate expectations in major markets.
•    Why higher benchmark yields have not been enough to make much of longer-duration or lower-quality credit compelling today.
•    A look at two selective opportunities: CoreWeave, tied to AI infrastructure, and a fallen angel with potential catalysts and downside protection.
•    How AI is being used inside Mawer’s research process to sort through a vast global credit universe and surface new ideas.
•    Why massive borrowing by hyperscalers to fund AI CapEx could pressure investment-grade spreads over the next 12 to 18 months.
•    Early signs of stress in leveraged loans and private credit, and why Brian sees growing evidence of “decay” in parts of the lending market.
