Introduction to Credit Ratings

Credit ratings originated in the early 20th century in the United States, primarily to assess the creditworthiness of railroads and other bond issuers. Developed by John Moody in 1909, this system categorized securities by default risk. As financial markets evolved, Credit Rating Agencies (CRAs) expanded their influence globally across bond markets and corporate finance and eventually became integrated into regulations worldwide. In 2004, Caribbean Information & Credit Rating Services Limited (CariCRIS) was established and focused on adding regional and local perspectives to the ratings of Caribbean entities. We have completed over 1000 ratings, including initial ratings and annual reviews to date. Our ongoing efforts through various educational activities and market engagement aim to enhance the understanding and awareness of credit ratings, the process and benefits.

A credit rating is a current opinion on the relative creditworthiness of an entity or debt issue. It refers to the likelihood of timely repayment of debt or potential for debt default. Lenders typically use a credit rating when advancing funds to borrowers in order to assess the risk associated with loaning that money to a borrower. While typically known for its application in the financial sector, credit ratings can be derived for any sector in the corporate space, as well as for a sovereign that issues debt. Therefore, whether a company is raising capital through bonds, or a government is issuing debt securities, lenders rely on credit ratings to evaluate the potential default risk of the borrower. These ratings provide valuable insights into the borrower’s financial health, past repayment behaviour, and ability to manage current and future obligations responsibly.

Credit ratings are typically assigned by CRAs. CariCRIS is the only CRA based in the Caribbean. CariCRIS assesses companies on a regional and national scale as opposed to international CRAs that would assess on a global scale. A regional scale rating is an opinion on the creditworthiness of an entity relative to other entities in a defined region (Caribbean) whereas a national scale rating is an opinion on the creditworthiness of an entity relative to other entities within a specific nation. There are several international CRAs, with Standard and Poor’s, Fitch and Moody’s being amongst the most recognized. CariCRIS, like all other CRAs, employs rigorous methodologies to analyse an array of quantitative and qualitative factors when assessing creditworthiness. After thorough evaluation, CRAs assign a credit rating ranging from high credit quality (low credit/default risk) to poor credit quality (high credit/default risk).

The rating scale used by CRAs varies, but generally consists of letter grades or numerical scores. For example, Standard & Poor’s and Fitch Ratings use letter grades ranging from ‘AAA’ (highest credit quality) to ‘D’ (default), while Moody’s employs a combination of letters and numbers. In the regional market, CariCRIS also uses letter grades ranging from ‘AAA’ to ‘D’. The primary distinction in our rating system is the use of prefixes to indicate whether a rating is on a regional or national scale. Regional ratings are prefixed with “Cari” to denote their broader regional scope, while national scale ratings use a country-specific prefix, such as “tt” for Trinidad and Tobago. For instance, a rating of CariAA signifies that the entity has been assessed against regional benchmarks and peers within the industry across the entire region, achieving an AA rating. Conversely, a ttAA rating denotes that the entity’s performance has been evaluated in comparison to industry benchmarks and peers specifically within Trinidad and Tobago.

Each rating category conveys a distinct level of credit risk, enabling lenders to make informed decisions about lending or investing. A high credit rating signifies a strong credit profile and a lower likelihood of default. In real world application, borrowers with excellent credit ratings can access credit at favourable terms, such as lower interest rates and higher borrowing limits. Conversely, a low credit rating indicates higher credit risk, which may result in higher borrowing costs or difficulty obtaining credit altogether. For businesses and governments, credit ratings influence investor confidence, market perception, and the cost of capital.
