The Bloomberg Aggregate Bond Index: What Is It?
Bond traders, mutual fund managers, and exchange-traded fund (ETF) managers utilize the Bloomberg Aggregate Bond Index, also known as “the Agg,” as a benchmark to assess their respective performance.
The Wilshire 5000 Total Stock Index is to the equities market what the Agg is to the bond market.
Only since August 2021 has the index been referred to as the Bloomberg Agg. For an extended period, it was the Barclays Agg. After buying Barclays fixed-income indexes in 2016, Bloomberg rebranded the indexes as Bloomberg Barclays indices for the next five years. Right now, they’re all just called Bloomberg.
Recognizing the Aggregate Bond Index for Bloomberg
Most people agree that one of the best indices of the entire bond market is the Bloomberg Aggregate Bond Index.
To replicate the entire universe of bonds in the market, the index consists of corporate bonds, government Treasury securities, mortgage-backed securities (MBS), asset-backed securities (ABS), and municipal bonds. It monitors bonds with at least investment-grade quality. The investment bank Kuhn, Loeb & Co. established earlier indices in 1973, which are the source of Agg’s history. The investment bank established two indices: a corporate bond index and an index tracking U.S. government bonds.
The Bloomberg Aggregate Bond Index’s composition
The Agg index’s composition aims to represent the entire range of investment-grade bonds traded in the United States. There are over 10,000 issues in it. U.S. Treasury bonds make up around 40% of the index. The residual elements signify the debt of significant sectors such as utilities, real estate, manufacturing, and finance.
A linked ETF to the Agg will closely mirror this distribution. The iShares AGG ETF, for instance, consists of roughly 10,000 stocks. The ETF’s composition as of January 22, 2022, is as follows: 10.91% Federal National Mortgage Association, 5.65% Government National Mortgage Association, 5.36% Uniform MBS, 4.5% Federal Home Loan Mortgage Corporation, and 39.17% connected to U.S. Treasuries. Bonds issued by Goldman Sachs, Bank of America, JPMorgan Chase, Morgan Stanley, and the Federal Home Loan Mortgage Corporation make up less than 1% of the total.
ETFs and Funds That Track the Average
An index-tracking mutual fund or exchange-traded fund (ETF) is an option for investors who want to have the most exposure to the fixed-income market.
The most significant bond ETF is the iShares Core U.S. Aggregate Bond ETF, which had over $90 billion in net assets as of January 22, 2022.
One of the largest bond mutual funds in the world, Vanguard Total Bond Market Index Fund Admiral Shares (VBTLX), which had $316.2 billion in assets as of January 22, 2022, tracks the Bloomberg U.S. Aggregate Float Adjusted Index.
U.S. government debt makes up 65.4% of the Vanguard Total Bond Market Index Fund’s assets, with AAA-rated debt making up 3.7%, A.A. debt accounting for 3.2%, A debt accounting for 12.1%, and BBB debt accounting for 15.5%.
Conclusion
- The Bloomberg Aggregate Bond Index shows how the U.S. investment-grade bond market is doing.
- Investment-grade government and business bonds make up the index.
- One exchange-traded fund (ETF) that follows the index is the iShares Core U.S. Aggregate Bond ETF (AGG).
