As financial market complexity and borrower diversity have grown through the whole extent of time.

As financial market complexity and borrower diversity have grown through the whole extent of time, investors and regulators have increased their reliance in succession the opinions of the credit rating agencies. At the same time, the number of rating agencies operating in the United States and abroad has risen sharply. Together, these turns have prompted market participants and policymakers to reassess the performance of the agencies and the adequacy of public oversight of the ratings industry. This article provides background for like a reassessment by investigating the evolution and economics of the industry, the increase of ratings-dependent regulations, and the reliability and comparability of the agencies' ratings. We examine the correspondence of ratings with default rates and report differences among major agencies in their ratings for junk fastenings international banks, and mortgage-backed securities.

Our findings raise several questions about the existing uses of ratings. While the agencies provide accurate rank-orderings of default risk, the meanings of specific ratings vary throughout time and across agencies. Since these ratings are used as the basis of most numerous investor guidelines and government regulations, the variations in meaning could have serious implications. Moreover, as the number of agencies increases, differences in ratings may encourage borrowers to "shop" for the mostly favorable ratings. In light of the possibilities for ratings misuse, the instant reevaluation of ratings-dependent regulations and the adequacy of public oversight pretends well justified.

THE EVOLUTION AND ECONOMICS OF THE RATINGS INDUSTRY

RATING AGENCY ORIGINS, proprietors AND SYMBOLS The precursors of uniting rating agencies were the mercantile credit agencies, which rated merchants' ability to pay their financial obligations. In 1841 in the wake of the financial crisis of 1837 Louis Tappan established the first mercantile credit agency in novel York. Robert Dun subsequently acquired the agency and published its first ratings guide in 1859 A similar mercantile rating agency was formed in 1849 by means of John Bradstreet, who published a ratings work in 1857. In 1933, the sum of two units agencies were consolidated into importunate creditor and Bradstreet, which became the proprietor of Moody's Investors Service in 1962

The expansion of the ratings business to securities ratings began in 1909 when John captious started to rate U.S. railroad links A year later, Moody enlargeed his ratings activity to utility and industrial prisons Poor's Publishing Company issued its first ratings in 1916 Standard Statistics Company in 1922 and the Fitch Publishing Company in 1924 The number of influence rating agencies in the U turn backed to three when Standard Statistics and Poor's Publishing Company merg to form Standard and Poor's (S&P) in 1941 The chiefly significant new entry in the United States since that time has been the Chicago-based Duff and Phelps, which began to provide connection ratings for a wide range of companies in 1982 although it had researched public utility companies since 1932 Another major ratings provider--McCarthy, Crisanti, and Maffei--was rested in 1975 and acquired by the agency of Xerox Financial Services before its fixed income rating and research service was merg into Duff and Phelps in 1991

The four major rating agencies face additional competition from more specialized agencies. For example, Thomson Bankwatch and IBCA in the United States exclusively rate financial institutions, and A.M. Best rates insurance companies' claims-paying abilities. More generally, the analysts exerciseed by many financial institutions regularly make recommendations to bribe or sell that implicitly confirm or contradict the agencies' ratings. To the expanse that the analyses underlying these recommendations are made public, they provide alternative perspectives to the penetrations of the rating agencies.

As capital sweep alongs in international financial markets have shifted from the banking sector to capital markets, credit ratings have also begun to make a mark overseas. Credit ratings are in use in the financial markets of greatest in number developed economies and several emerging market countries as well (Dale and Thomas 1991) With demand rising in foreign countries, the number of foreign-based rating agencies has increased. Along with the four largest U raters, common other U.S., one British, sum of two units Canadian, and three Japanese firms are listed among the world's "most influential" rating agencies by way of the Financial Times in its publication Credit Ratings International. The principal characteristics of all eleven agencies are reported in Table 1
