Morgan Stanley: AI Financing Heatwave Gaining Traction, Overweight Data Center Debt

Overview

This report is Morgan Stanley's periodic tracking update on the global AI-related debt financing market. The core conclusion is that the financing cycle for AI infrastructure construction is accelerating. Although issuance pace in the U.S. slowed somewhat in May, overall fundamentals remain strong, and supply is projected to rebound significantly in H2 2026. Institutions have clearly stated they are overweighting high-yield data center debt and hold positive views on data center securitization products, believing the current period offers a window to deploy into AI infrastructure credit assets.

Core views

Issuance Pace and Total Forecast: April was the busiest month year-to-date, with AI-related issuance exceeding $74 billion. Project finance structures accounted for 85% of high yield bond supply and 40% of investment grade supply. While the U.S. market entered a 'breathing spell' in May, hyperscaler cloud vendors issued approximately $24 billion in debt in non-U.S. currencies including Euros, Canadian Dollars, Swiss Francs, and Japanese Yen. As of end-May, global AI-related issuance in 2026 reached $236 billion, more than four times the same period in 2025. The report forecasts total global AI-related supply in 2026 will reach approx. $570 billion; as equity teams forecast hyperscaler cash Capex breaking $1 trillion in 2027, H2 issuance could accelerate further. High Yield Debt and Leveraged Finance Views: Institutions explicitly overweight high-yield data center debt. Since H2 2025, sector issuance has accelerated (approx. $42 billion), with approx. $27 billion YTD so far. The bullish logic lies in defensive credit characteristics, limited lease risk, and project finance-style structured protection clauses (e.g., debt reserve accounts, amortization requirements, lockbox mechanisms). Currently, 12 data center construction transactions are trading publicly (vs. 4 at end of 2025), and most include mitigation measures for construction risk such as guarantees and limited termination rights. Investment Grade and Hyperscaler Dynamics: Hyperscalers have issued $159 billion year-to-date, including $52 billion in non-U.S. debt. While balance sheet metrics remain healthy (median rating AA-, Net Leverage 1.0x), leverage has risen by 0.9x since tracking began in Q3 2025. Notably, issuers' weight in Euro/Pound benchmark indices remains far below the Dollar Index, meaning huge room exists for non-USD currency financing expansion. Additionally, Chip Financing is becoming a new focus; compared to data center construction loans, terms are shorter and require full amortization, expected to see sustained growth in investor demand. Securitization Products (ABS/CMBS): Securitization market issuance was light in April and May, with only one transaction each, leading to spread narrowing due to supply depletion. The report believes data center securitization products are attractive throughout the capital structure, especially ABS BBB tranche value is highest. Although ABS DSCR gradually decreases as master trust size grows, it remains far above triggers; CMBS DSCR compressed in high-interest rate environment, but collateral quality metrics (e.g. occupancy >90%) remain stable.

Analysis framework

The report adopts a 'top-down total volume forecasting + bottom-up asset class breakdown' analytical framework. First, derive annual debt financing needs by tracking hyperscaler Capex plans; then segment the market into three sub-sectors: Investment Grade, High Yield/Leveraged Finance, and Securitization Products, analyzing supply/demand dynamics, spread movements, and credit metrics separately; finally combine primary market issuance pricing data with secondary market performance to assess relative value across different asset classes. This method links physical industry Capex cycles with financial market credit supply cycles, helping investors identify structural opportunities.

Methodology notes

• Industry/Industrial Analysis FrameworkSupply Chain Upstream/Downstream Transmission

  Deriving debt financing demand from hyperscaler capital expenditures

  The report's core logic rests on a transmission chain of 'Physical Investment Drives Financial Demand': first forecast downstream cloud vendor cash Capex, then calculate debt financing scale needed for midstream data center construction and upstream chip procurement. This method allows bond investors to anticipate credit market supply pressure by tracking tech giants' earnings and guidance.

• Fixed Income and Credit AnalysisSpread analysis

  Technical factors dominate short-term pricing vs. Fundamentals support long-term value

  The report notes current price action is primarily driven by 'issuance expectations' (technical) rather than fundamental deterioration. This means spreads may widen when issuance surges, offering buying opportunities; while issuance slows (e.g. May), spreads tighten quickly. Understanding this distinction helps investors distinguish temporary supply/demand imbalances from permanent credit risk revaluation amidst market volatility.

• Fixed Income and Credit AnalysisSpreads and Asset Quality

  Project finance structured protection as credit enhancement tool

  When evaluating high-yield data center debt, the report not only looks at issuer ratings but emphasizes the role of 'structured protection' (e.g. debt reserves, lockboxes, amortization) in boosting recovery rates. This explains why BB-rated data center debt gets an Overweight rating: its actual default loss risk is lower than same-rating ordinary corporate bonds because cash flows are strictly locked for debt service.

Impact & implications

For fixed income investors, AI infrastructure has become an不可忽视 incremental asset category. The report hints that although short-term supply surge may cause spread volatility, strong underlying demand and improving structured protection provide safety margins for medium-long term allocation. Especially for investors seeking yield, high-yield data center debt and ABS BBB tranches offer superior risk-adjusted return potential compared to traditional industrial/consumer sectors. Meanwhile, hyperscalers' expansion into non-USD markets provides European and Asian local investors with scarce targets to participate in the AI theme.

Risks

• Supply Shock Risk: If H2 2026 issuance concentrates release beyond expectations, spreads may widen temporarily
• Leverage Rise: Hyperscaler leverage rose 0.9x from low point; if Capex continues exceeding expectations while EBITDA growth lags, credit quality could come under pressure
• Construction Risk: Many high-yield debts are under-construction projects; delays or cost overruns may trigger structural clauses or impact cash flow

What to watch

• Pace and scale of acceleration in AI-related debt issuance in H2 2026
• Issuance frequency and pricing of hyperscalers in non-USD currency markets
• Evolution of terms in chip financing structures and secondary market liquidity
• Changes in DSCR and LTV metrics for new Data Center ABS/CMBS issuances
