What are the top three rating companies?

In some reports, we often see that some countries have fallen into civil strife because of the downgrade of international rating companies, or a financial market has emerged because of the upgrade of international rating companies. Do you know which three rating companies are the most influential in the world? What are the three major rating companies? The three most influential rating companies in the world are Standard & Poor's, Moody's Investors Service and Fitch Ratings. These companies not only have sufficient rating authority at the company level, but also have sufficient authority at the national sovereign credit level. For example, when the United States imposed sanctions on Iran, rating companies immediately downgraded Iran's national sovereign credit rating to help the United States impose sanctions. In this regard, we can know the international influence of the three major rating companies, as follows: 1 Standard & Poor's, 1860 rating agency founded by Henry Varnom Poole, and 1975 obtained the approval of the SEC of the US Securities and Exchange Commission. 2 Moody's Investors Service Company was founded by John Moody in 1909, and originally made a fortune with bond credit rating. So far, Moody's has been an international authoritative investment credit rating agency and a famous financial information publishing company. 3 Fitch International Credit Rating Company, 19 13 is a rating agency founded by John Fitch, but this company is the only European-funded institution. As far as these internationally influential rating agencies are concerned, we can find that they are basically controlled by Europe and America, so there is still a long way to go for the development of domestic rating agencies in China.
