Role of Rating Agencies

Credit Rating Agencies (CRAs) assess the creditworthiness of a company. They assign ratings (AAA, AA, BBB) which tell investors "How likely is this company to repay its debt?"

Function in Governance

1. Independent Monitor

They act as a third eye. Since retail investors cannot visit the factory or interview the CFO, they rely on the Agency's report.

  • Reduces Information Asymmetry.

2. Signal of Governance Quality

A high rating (AAA) usually implies strong governance (transparent accounts, stable management). A sudden downgrade often flags governance issues (e.g., hiding debt).

3. Disciplining Mechanism

Companies are terrified of downgrades. A downgrade raises their interest cost.

  • This fear forces management to behave responsibly to maintain their rating.

Failures of Rating Agencies

  • Conflict of Interest: The "Issuer-Pays" model. The company being rated pays the agency. This creates a temptation to give a good rating to keep the client.
  • 2008 Crisis: Agencies gave AAA ratings to junk mortgage bonds (CDOs) because they earned huge fees.
  • IL&FS Crisis (India): CRAs maintained high ratings on IL&FS right until it defaulted.
Note

Gatekeepers: Along with Auditors, CRAs are considered "Market Gatekeepers". When they fail (as in Enron or IL&FS), the governance system collapses.
