How Rating Notching works
Ratings summarize an agency's view of creditworthiness within a defined methodology, while migration describes movement between rating categories over time. Markets often reprice before formal rating actions, but ratings still affect mandates, collateral rules and investor eligibility. Rating Notching is interpreted within an agency's published methodology and should not be treated as a market-price forecast. Investors compare it with spreads, fundamentals and rating-sensitive mandates because the market can reprice before or after a formal agency action.
Why it matters to credit investors
Rating Notching matters because many investors, indices, collateral frameworks and risk systems use ratings as eligibility or capital inputs. A migration event can therefore create forced flows even when the underlying fundamental change is gradual.
