KBRA Affirms AAA Rating for Commonwealth of Massachusetts - Commonwealth Transportation Fund Revenue Bonds; Outlook is Stable
4 Sep 2025 | New York
KBRA affirms the long-term rating of AAA with a Stable Outlook for the Commonwealth of Massachusetts - Commonwealth Transportation Fund (CTF) Revenue Bonds.
Key Credit Considerations
The rating was affirmed because of the following key credit considerations:
Credit Positives
- Very broad and resilient nature of CTF pledged revenues which, to date, have generated more than 4.0x coverage of maximum annual debt service.
- Extensive legal protections that collectively and effectively insulate pledged revenues from Commonwealth budget operations.
- The Commonwealth’s diverse, wealthy, and growing economy.
Credit Challenges
- The motor fuels portion of pledged revenues (~53.3% of FY 2025 pledged revenues) is economically sensitive and vulnerable to declines during recessionary periods.
- Longer term, structural shifts in fuel consumption patterns driven by the continued phase-in of electric, hybrid, and increasingly efficient conventional vehicles may pressure the motor fuels portion of pledged revenues.
The Stable Outlook reflects KBRA’s expectation that pledged revenues will remain resilient and unlikely to decline significantly enough to impair coverage of debt service, even under very adverse economic conditions. Further, KBRA believes the Commonwealth has no meaningful incentive to divert or dilute the pledged revenues in ways that would be detrimental to bondholders.
Rating Sensitivities
For Upgrade
- Not applicable at AAA rating level
For Downgrade
- An unlikely scenario where there was a substantial and sustained decline in pledged revenues.
