AI capex and the new credit cycle

Key arguments

• AI infrastructure spending is increasing capital intensity, expanding credit supply, and driving dispersion across credit sectors and issuers.
• Investment-grade investors focus on the balance between growth and rising capital intensity; AI winners often include hyperscalers, semiconductor firms, and infrastructure providers.
• High-yield markets are seeing increasing dispersion; AI beneficiaries often include independent power producers, utilities, telecom infrastructure providers, and industrial suppliers.
• Private credit markets face growing financing demand, but underwriting and structuring quality becomes critical to differentiate durable cash flows from execution risks.
• Securitized credit investors emphasize structure and collateral quality, wary of optimistic repayment timelines and refinancing assumptions.
• The AI capex cycle is less sensitive to interest rate changes, with constraints more likely from market-based channels like investor demand and equity valuations.

2. The implications of this structural trend differ across the credit market spectrum, but the common theme is one of increasing dispersion across sectors and issuers and the need for careful analysis of capital allocation, financing, and execution risk. · medium-term
3. The AI build-out is unlikely to follow a smooth path given the potential for supply bottlenecks, execution challenges, and market financing fatigue, which increase the risk of uneven outcomes. · medium-term
