Bond credit rating

Last updated

In investment, the bond credit rating represents the credit worthiness of corporate or government bonds. The ratings are published by credit rating agencies and used by investment professionals to assess the likelihood the debt will be repaid.

Credit rating agencies

Credit rating is a highly concentrated industry with the "Big Three" credit rating agenciesFitch Ratings, Moody's and Standard & Poor's (S&P) – controlling approximately 95% of the ratings business. [1] [2]

Credit rating agencies registered as such with the SEC are "nationally recognized statistical rating organizations". The following firms are currently registered as NRSROs: A.M. Best Company, Inc.; DBRS Ltd.; Egan-Jones Rating Company; Fitch, Inc.; HR Ratings; Japan Credit Rating Agency; Kroll Bond Rating Agency; Moody's Investors Service, Inc.; Rating and Investment Information, Inc.; Morningstar Credit Ratings, LLC; and Standard & Poor's Ratings Services.

Under the Credit Rating Agency Reform Act, an NRSRO may be registered with respect to up to five classes of credit ratings: (1) financial institutions, brokers, or dealers; (2) insurance companies; (3) corporate issuers; (4) issuers of asset-backed securities; and (5) issuers of government securities, municipal securities, or securities issued by a foreign government. [3]

In Asia, the regulated and recognized credit rating agencies in the domestic markets are – in China: China Chengxin International (CCXI), China Lianhe Credit Rating (Lianhe Ratings), CSCI Pengyuan, New Century Zixin Assessment Investment Service; in Japan: Rating and Investment Information (R&I); in India: ICRA (ICRA), Credit Analysis and Research (CARE) and CRISIL.

Credit rating codes and classes

The credit rating is a financial indicator to potential investors of debt securities such as bonds. These are assigned by credit rating agencies such as Moody's, Standard & Poor's, and Fitch, which publish code designations (such as AAA, B, CC) to express their assessment of the risk quality of a bond. Moody's assigns bond credit ratings of Aaa, Aa, A, Baa, Ba, B, Caa, Ca, C, as well as WR and NR for 'withdrawn' and 'not rated' respectively. [4] Standard & Poor's and Fitch assign bond credit ratings of AAA, AA, A, BBB, BB, B, CCC, CC, C, D. Currently there are only two companies in the United States with an AAA credit rating: Microsoft and Johnson & Johnson. [5] These individual codes are grouped into broader classes described as "investment grade" or not, or in numbered tiers from high to low.

In addition to the rating codes, agencies typically supplement the current assessment with indications of the chances for future upgrades or downgrades over the medium term. For example, Moody's designates an Outlook for a given rating as Positive (POS, likely to upgrade), Negative (NEG, likely to downgrade), Stable (STA, likely to remain unchanged), or Developing (DEV, contingent on some future event).

Investment grade

A bond is considered investment grade or IG if its credit rating is BBB− or higher by Fitch Ratings or S&P, or Baa3 or higher by Moody's, the so-called "Big Three" credit rating agencies. Generally they are bonds that are judged by the rating agency as likely enough to meet payment obligations that banks are allowed to invest in them.

Ratings play a critical role in determining how much companies and other entities that issue debt, including sovereign governments, have to pay to access credit markets, i.e., the amount of interest they pay on their issued debt. The threshold between investment-grade and speculative-grade ratings has important market implications for issuers' borrowing costs.

Bonds that are not rated as investment-grade bonds are known as high yield bonds or more derisively as junk bonds.

The risks associated with investment-grade bonds (or investment-grade corporate debt) are considered significantly higher than those associated with first-class government bonds. The difference between rates for first-class government bonds and investment-grade bonds is called investment-grade spread. The range of this spread is an indicator of the market's belief in the stability of the economy. The higher these investment-grade spreads (or risk premiums) are, the weaker the economy is considered.

Criticism

Until the early 1970s, bond credit ratings agencies were paid for their work by investors who wanted impartial information on the credit worthiness of securities issuers and their particular offerings. Starting in the early 1970s, the "Big Three" ratings agencies (S&P, Moody's, and Fitch) began to receive payment for their work by the securities issuers for whom they issue those ratings, which has led to charges that these ratings agencies can no longer always be impartial when issuing ratings for those securities issuers. Securities issuers have been accused of "shopping" for the best ratings from these three ratings agencies, in order to attract investors, until at least one of the agencies delivers favorable ratings. This arrangement has been cited as one of the primary causes of the subprime mortgage crisis (which began in 2007); some securities, particularly mortgage-backed securities (MBSs) and collateralized debt obligations (CDOs), were rated highly by the credit ratings agencies and thus heavily invested in by many organizations and individuals, but were then rapidly and vastly devalued due to defaults, and fear of defaults, on some of the individual components of those securities, such as home loans and credit card accounts. Other countries are beginning to mull the creation of domestic credit ratings agencies to challenge the dominance of the "Big Three", for example in Russia, where the ACRA was founded in 2016. [9]

Municipal bonds

Municipal bonds are instruments issued by local, state, or federal governments in the United States. Until April–May 2010, Moody's and Fitch were rating municipal bonds on the separate naming/classification system which mirrored the tiers for corporate bonds. S&P abolished its dual rating system in 2000.

Default rates

The historical default rate for municipal bonds is lower than that of corporate bonds. A potential misuse of historic default statistics "is to assume that historical average default rates represent the 'probability of default' of debt in a particular rating category. However, [...] default rates can vary significantly from one year to the next and the observed rate for any given year can vary significantly from the average." [10]

<span class="mw-page-title-main">Credit rating agency</span> Company that assigns credit ratings

A credit rating agency is a company that assigns credit ratings, which rate a debtor's ability to pay back debt by making timely principal and interest payments and the likelihood of default. An agency may rate the creditworthiness of issuers of debt obligations, of debt instruments, and in some cases, of the servicers of the underlying debt, but not of individual consumers.

A credit rating is an evaluation of the credit risk of a prospective debtor, predicting their ability to pay back the debt, and an implicit forecast of the likelihood of the debtor defaulting. The credit rating represents an evaluation from a credit rating agency of the qualitative and quantitative information for the prospective debtor, including information provided by the prospective debtor and other non-public information obtained by the credit rating agency's analysts.

Fitch Ratings Inc. is an American credit rating agency. It is one of the three nationally recognized statistical rating organizations (NRSRO) designated by the U.S. Securities and Exchange Commission and is considered as being one of the "Big Three credit rating agencies", along with Moody's and Standard & Poor's.

A collateralized debt obligation (CDO) is a type of structured asset-backed security (ABS). Originally developed as instruments for the corporate debt markets, after 2002 CDOs became vehicles for refinancing mortgage-backed securities (MBS). Like other private label securities backed by assets, a CDO can be thought of as a promise to pay investors in a prescribed sequence, based on the cash flow the CDO collects from the pool of bonds or other assets it owns. Distinctively, CDO credit risk is typically assessed based on a probability of default (PD) derived from ratings on those bonds or assets.

A structured investment vehicle (SIV) is a non-bank financial institution established to earn a credit spread between the longer-term assets held in its portfolio and the shorter-term liabilities it issues. They are simple credit spread lenders, frequently "lending" by investing in securitizations, but also by investing in corporate bonds and funding by issuing commercial paper and medium term notes, which were usually rated AAA until the onset of the financial crisis. They did not expose themselves to either interest rate or currency risk and typically held asset to maturity. SIVs differ from asset-backed securities and collateralized debt obligations in that they are permanently capitalized and have an active management team.

Bond insurance, also known as "financial guaranty insurance", is a type of insurance whereby an insurance company guarantees scheduled payments of interest and principal on a bond or other security in the event of a payment default by the issuer of the bond or security.
