What the company or idea is
Moody’s Ratings is the credit ratings division of Moody’s Corporation, rebranded from Moody’s Investors Service in March 2024, and one of the Big Three credit rating agencies.
How it actually makes money
Moody’s Ratings charges issuers of debt securities—governments, municipalities, corporations, banks, and structured finance vehicles—for assigning credit ratings to their bonds and other debt instruments.
What works
Its standardised Aaa-to-C scale is globally recognised, embedded in regulation, and used by investors, central banks, and exchanges to determine eligibility, collateral value, and capital requirements.
What does not
It does not assess or guarantee repayment. Its ratings measure only expected investor loss in default—not likelihood of default alone, nor broader economic or political risk—and carry no enforcement mechanism or liability for accuracy.
What to take from it
The gap between Moody’s founding purpose—to publish bond statistics—and its current function—as a paid gatekeeper of market access—reveals how financial infrastructure becomes entrenched through regulatory adoption, not technical superiority.
Is it worth your time
Yes—if you need to understand how credit risk is priced, certified, and commodified in global capital markets; no—if you assume its ratings reflect objective financial truth rather than a paid certification process.
