What Is a AAA Credit Rating?

AAA is the highest possible rating that may be assigned to an issuer’s bonds by any of the major credit-rating agencies. AAA-rated bonds have a high degree of 澳洲幸运5开奖号码历史查询:creditworthiness because their issuers are e🌳asily able to meet financial commitments and have the lowest risk o🎶f default.

Rating agencies 澳洲幸运5开奖号码历史查询:Standard & Poor’s (S&P) and 澳洲幸运5开奖号码历史查询:Fitch Ratings use the letters AAA to identify bonds with the highest 澳洲幸运5开奖号码历史查询:credit quality, while Moody’s uses a slightl🅺y different Aaa to signify a bond’s top-tier credit rating.

Key Takeaways

  • The highest possible rating that a bond may achieve is AAA, which is only bestowed upon those bonds that exhibit the highest levels of creditworthiness.
  • This AAA rating is used by Fitch Ratings and Standard & Poor’s, while Moody’s uses a similar Aaa lettering.
  • Bonds that receive AAA ratings are viewed as the least likely to default. 
  • Issuers of AAA-rated bonds generally have no trouble finding investors, although the yield offered on these bonds is lower than other tiers because of the high credit rating.

Understanding AAA Credit Ratings

澳洲幸运5开奖号码历史查询:Credit ratings are assessments or opinions of the creditworthiness of a business or government. As such, they provide an alert of the likeliꦓhood that the subject will live up to their financial obligations by paying their bills. Investors can use these ratings to decide whether countries𝄹 and bond offerings are safe investments. These ratings are assigned by credit rating agencies, notably S&P, Moody's, and Fitch.

AAA and Aaa ratings are considered to be 澳洲幸运5开奖号码历史查询:investment grade. Since they are perceived to have the lowest risk of default, these instruments tend to offer the investors the lowest yields among bonds with similar maturity dates (lower risk equals lower return). The term default refers to a bond issuer failing to fulfill its obligations, namely failing to make semiannual interest payments or repay the 澳洲幸运5开奖号码历史查询:principal amount when due.

AAA ratings are given to government debt and companies’ corporate bonds. The global 澳洲幸运5开奖号码历史查询:credit crisis of 2008 resulted in a number of companies losing their AAA rating, most notably General Electric (GE). As of August 2023, only two companies held the AAA rating outright: Microsoft (MSFT) and Johnson & Johnson (JNJ). Apple (AAPL) is split, with an Aaa rating by Moody’s and an AA+ (one notch below AAA) from S&P.

Even the United States suffered a ratings cut by S&P, to AA+ in 2011—losing its vaunted AAA status due to political infighting over raising the 澳洲幸运5开奖号码历史查询:debt ceiling. Moody’s and Fitch maintained the U.S. at Aaa and AAA ratings, respectively. That is, until August 2023 when Fitch downgraded the U.S.'s long-term ratings from AAA to AA+. The agency cited potential issues with financial deterioration over the next three years and rising 澳洲幸运5开奖号码历史查询:national debt.

Important

Rather than restricting their fixed-income exposure to AAA-rated bonds, investꦍors should consider balancing those investment꧟s with higher income-producing bonds, such as high-yield corporates.

Types of AAA-Rated Bonds

Municipal

Municipal bonds can be issued as either revenue bonds o💝r general obligation bonds, with♔ each type relying on different sources of income.

Revenue bonds, for example, are paid using fees and other specific income-generating sources, like city pools and sporting venues. On the other hand, general obligation bonds are backed by the issuer’s ability to raise capital through levying taxes. State bond♋s rely on state income taxes, while local sꦐchool districts depend on property taxes.

Secured and Unsecured

Issuers 🌺can sell both secured and unsecured bonds. Each type of bond carries with it a different risk profile.

A 澳洲幸运5开奖号码历史查询:secured bond means that a specific asset is pledged as 澳洲幸运5开奖号码历史查询:collateral for the bond, and the creditor has a claim on the asset if the issuer defaults. Secured bonds may be collateralized with tangible items such as equipment, machinery, or rea♚l estate. Secured collateralized offerings may have a higher credit rating than unsecured bonds sold by the same issuer.

Conversely, 澳洲幸运5开奖号码历史查询:unsecured bonds are simply backed by the issuer’s promise to pay. Therefore, the 澳洲幸运5开奖号码历史查询:credit rating of such instru꧋ments relies heavily on the issuer’s inc☂ome sources and business outlook.

Benefits of a AAA Rating

A high credit rating lowers the cost of borrowing for the issuer (or borrower). Therefore, it stands to reason that companies with high ratings are better positioned to borrow large sums of money than 澳洲幸运5开奖号码历史查询:fixed-income instruments with lesser credit ratings. And a low cost of borrowing affor꧑ds fir🐻ms a substantial competitive advantage by letting them easily access credit to grow their businesses.

For example, a business may use the i𝓰ncoming funds from a new bond issue to launch a new product line, set up a shop in a new location, or acquire a competitor. All of these initiatives can help a company increase its market share and thrive over the long haul.

Why Is a Credit Rating So Important?

The level of credit rating that an issuer receives has significant implications on the cost of borrowing in the open market. The better the credit rating—with A🍃AA being the best—the lower the cost to borrow, and vice versa.

As an investor, you’ll need to balance the risk🎃 you’re willing to take against the yield you’re seeking.

Who Decides What Credit Rating a Debt Issuer Receives?

There are three maj🐷or credit rating agencies: Standard & Poor’s (S&P), Moody’s, and Fitch. They assess a debt issuer’s creditworthiness and ability to pay interest and principal on bonds based on multiple factors, such as the company’s cash ꧅flow, the amount of other outstanding debt, and the business outlook for the issuer, to name just a few criteria.

What Does the AAA Credit Rating Mean?

The AAA credit rating is only given to the most creditworthy debt issuers and allows investors to gauge the amount of risk in their fixed-income 澳洲幸运5开奖号码历史查询:portfolio. Conservative investors will typically sacrifice return or y🐻ield to own the highest credit rating issues available.

The Bottom Line

Credit ratings are assigned to debt issues and bonds by the three m🐼ajor debt-rating agencies: S&P, Moody’s, and Fitch. Their credit ratings have a strong influence on the cost of borrowing for the issuer. The better the credit rating, the lower the cost to borrow.

AAA/Aaa ratings are the highest ratings issued by the credit-rating agencies and likely result in the lowest borrowing costs or yields. Investors 😼seeking a better return should look down the credit-ratings scale for bond issuers with lower ratings and higher yields.
