Maryland Treasurer Dereck Davis announced the state will no longer contract with Moody's Investors Service, twelve months after the agency stripped Maryland of its AAA rating and moved it to Aa1 in February 2024. The termination makes Maryland the first U.S. state to formally sever a paid relationship with one of the three rating agencies that control $4.6 trillion in state and local government debt.

Moody's cited Maryland's structural budget challenges and pension liabilities in the downgrade, specifically pointing to $72 billion in unfunded pension obligations and recurring general fund deficits projected through fiscal 2028. The state disputed the methodology, arguing Moody's failed to account for legislative reforms passed in March 2024 that restructured $18 billion in teacher retirement obligations. Maryland continues to hold AAA ratings from S&P Global and Fitch, creating a split rating that typically costs issuers 12-18 basis points in additional borrowing costs on competitive deals.

The move exposes tension in the issuer-pays model that generates 87% of rating agency revenue. States and municipalities pay between $25,000 and $150,000 per bond issue for ratings, creating a structural conflict where issuers fund the agencies that evaluate them. Maryland paid Moody's an estimated $340,000 annually across its general obligation, transportation, and stadium authority programs. The termination means future Maryland issues will carry only two ratings instead of three, a configuration that some institutional mandates classify as insufficient coverage for certain fixed-income allocations.

The timing matters for two reasons. First, Maryland plans a $875 million general obligation issue in May 2025, now structured to price without Moody's participation. The state's advisors at PFM Financial expect the two-rating approach to widen spreads by 8-14 basis points versus recent comparable AAA state paper, adding roughly $2.1 million in interest costs over a twenty-year maturity. Second, the Maryland precedent arrives as Illinois and New Jersey—both split-rated states with Moody's as the restrictive rater—review their agency relationships ahead of fiscal 2026 budget certifications.

Allocators should watch for contagion effects across $47 billion in split-rated state GO debt currently outstanding. If additional states follow Maryland's path, the effective oligopoly held by S&P, Moody's, and Fitch begins to fracture along issuer-choice lines rather than regulatory mandate. The National Federation of Municipal Analysts noted in a March 2025 letter that single-agency terminations could create information asymmetry in secondary markets, particularly for retail holders who rely on rating stability as a liquidity signal. Moody's rates 43% of all state-level debt, a concentration that makes Maryland's decision a direct challenge to franchise economics.

Maryland's May issue will test whether the market prices credit quality or rating count. The state's debt service coverage sits at 11.2x, and its general fund balance equals 12.4% of expenditures, both metrics in the top quintile nationally. If the deal prices inside Moody's Aa1 curve and closer to the AAA benchmarks set by S&P and Fitch, other issuers will have permission to rethink the three-agency standard. The Commonwealth sells $4.8 billion annually across all programs.
