Thoughts on the Market
2026-10-19 · Hosted by Mike Wilson · Morgan Stanley
Executive Summary
Morgan Stanley's Carolyn Campbell explains how rising borrowing costs are becoming an unexpected obstacle for the AI data-center boom. Since January, five-year Treasury rates have climbed more than one percentage point, and credit spreads for data-center-backed bonds have widened too: the highest-rated data-center bonds yielded below 5% at the start of 2026 but are closer to 7% today.
Key Stories & Changes
1. Rising Rates Squeeze Data-Center Financing Economics
Five-year Treasury rates have risen more than one percentage point since January 2026
Highest-rated data-center asset-backed bonds yielded below 5% at the start of 2026; similar bonds now yield closer to 7%
Because rental income on these bonds is locked in via long-term leases signed well before financing, rising rates compress the margin between financing cost and fixed revenue
Morgan Stanley's analysis: once borrowing costs approach 8%, issuing these bonds becomes significantly more difficult under current financing terms
2. 2026 Issuance Trails Underlying Demand Growth
Data-center operators have issued roughly $15 billion in ABS and $7 billion in CMBS so far in 2026 — in line with last year's pace but below what the extraordinary growth in data-center demand would otherwise imply
Morgan Stanley views the issuance slowdown as temporary rather than structural
3. Capacity Growth Forecast and Financing Outlook
US data-center power capacity is forecast to grow from roughly 60 gigawatts today to 150 gigawatts by 2028, though power-availability constraints could leave actual capacity 30-40% below that projection
Morgan Stanley lowered its 2026/2027 securitized credit issuance forecast slightly to reflect the higher-rate environment but held 2028 estimates steady given the scale of lease capacity expected to come online
Overall forecast: $120-150 billion of securitized data-center credit supply over the next couple of years
Operators have several levers to manage the higher-rate environment: borrowing less against properties, accepting lower near-term investment returns, or using more flexible credit channels
4. Colocation Data Centers Seen as the More Resilient Segment
Hyperscaler data centers (large campuses leased to one or two tenants on 10-15 year leases) have dominated discussion, but Campbell flags colocation data centers — multi-tenant campuses with shorter leases — as where Morgan Stanley currently sees the most value
Colocation operators can more quickly reprice to rising rental rates given shorter lease terms and vacancy rates around 1%
This flexibility is seen as particularly valuable in a persistently elevated-rate environment
Trends Identified
1. Locked-In Leases Create a Structural Lag Between Rates and Revenue
The core tension described is timing: data-center rental income is fixed well before financing is arranged, so when rates rise quickly, financing costs outpace revenue — a structural mismatch rather than a demand problem, which explains why Morgan Stanley views the issuance slowdown as temporary.
2. Lease Structure Determines Resilience to Rate Shocks
The contrast between long-lease hyperscaler campuses and shorter-lease colocation facilities highlights a broader principle for data-center credit investors: flexibility to reprice rental income quickly is becoming more valuable than lease duration or tenant concentration as rates stay elevated. ---
Sentiment Analysis
Overall Market Sentiment: Constructive With a Financing Caveat
Morgan Stanley's tone is fundamentally optimistic about long-term data-center demand and build-out scale, while explicitly flagging near-term financing cost pressure as a real, quantifiable constraint.
Risk Factors Highlighted
Rate-driven financing squeeze: Rising Treasury rates and wider spreads are directly compressing the economics of data-center asset-backed financing.
8% borrowing-cost threshold: Morgan Stanley identifies this level as a point where current financing structures become significantly harder to execute.
Power-availability constraints: Capacity growth could fall 30-40% short of the 150-gigawatt 2028 projection if power supply constraints bind.
Locked-in lease mismatch: Fixed rental income signed before financing leaves operators exposed to financing-cost increases that revenue cannot immediately offset.
