Fund Basics and Index Tracking
SCHZ: Schwab U.S. Aggregate Bond ETF
The Schwab U.S. Aggregate Bond ETF, introduced on August 5, 2010, is part of Charles Schwab's initiative to provide low-cost investment options for retail investors. SCHZ is designed to track the Bloomberg U.S. Aggregate Bond Index.
As a passively managed ETF, SCHZ aims to closely replicate the index's holdings while keeping costs low. With an expense ratio of just 0.03%, it stands out as one of the most affordable ways to access the entire U.S. bond market.
To achieve this, SCHZ employs a full replication strategy, holding the actual bonds in the index rather than using derivatives.
AGG: iShares Core U.S. Aggregate Bond ETF
AGG, launched on September 22, 2003, has a longer history and is one of the earliest bond ETFs available. Part of BlackRock's iShares lineup, AGG also tracks the Bloomberg U.S. Aggregate Bond Index, offering similar market exposure to SCHZ.
Like SCHZ, AGG maintains an expense ratio of 0.03%. However, AGG's scale is significantly larger, managing over $90 billion in assets compared to SCHZ's roughly $20 billion. This larger asset base contributes to AGG's greater liquidity and narrower bid-ask spreads.
AGG also uses full replication but benefits from BlackRock's extensive bond trading infrastructure and institutional connections. These operational strengths can enhance portfolio management and execution efficiency, particularly in the bond market. These distinctions set the stage for a deeper look at how each fund handles tracking and risk.
Index Tracking Methods: Similarities and Differences
Both SCHZ and AGG track the Bloomberg U.S. Aggregate Bond Index, which includes a broad range of investment-grade bonds such as government, corporate, and mortgage-backed securities. The index applies specific criteria, like minimum maturity and size, to determine its composition. Both funds use full replication to align closely with the index, but AGG's larger scale allows it to more precisely reflect the index's makeup, leading to slightly tighter tracking performance.
Rebalancing occurs monthly for both funds to adjust for changes in the index, such as the addition of new bonds or the removal of those that no longer qualify. While this process is largely systematic, AGG's extensive market relationships may offer an edge when executing large bond trades efficiently.
Portfolio Holdings and Risk Analysis
Sector Mix and Credit Quality
Both funds align with the index's focus on investment-grade bonds, ensuring high credit standards across their portfolios.
As of June 30, 2025, SCHZ demonstrates a cautious stance on credit risk. The fund allocates 74.14% of its holdings to AA-rated bonds, 11.91% to BBB-rated bonds, and 11.38% to A-rated bonds. Additionally, it holds 2.49% in AAA-rated bonds, 0.07% in BB-rated bonds, and a minimal 0.01% in unrated securities. The average credit rating for SCHZ is AA-. Investors can expect similarly conservative credit profiles and sector allocations from both funds.
Duration and Interest Rate Risk
Duration, which gauges how bond prices react to interest rate fluctuations, is nearly identical for SCHZ and AGG due to their shared goal of tracking the same index. The Bloomberg U.S. Aggregate Bond Index includes a mix of bonds with varying maturities, from short-term government securities to long-term corporate debt. This broad range helps mitigate duration risks. However, neither fund offers unique protection against interest rate changes since they mirror the same index.
Risk Metrics and Price Volatility
Both funds exhibit low volatility and respond similarly to shifts in interest rates, credit conditions, and liquidity. This consistency reflects their commitment to closely tracking the index. Up next, we'll dive into performance and income metrics to further differentiate these ETFs.
Performance and Income Comparison
Returns and Dividend Yields
When comparing the income potential of these two bond ETFs, SCHZ edges out AGG in dividend yield. As of mid-October 2025, SCHZ offers a dividend yield of about 4.00%, while AGG comes in slightly lower at 3.81%. SCHZ also has an SEC yield of 4.08%, suggesting it may maintain its income advantage over time.
| Performance Metric | SCHZ | AGG |
|---|---|---|
| Dividend Yield | 4.00% | 3.81% |
| SEC Yield | 4.08% | N/A |
| Yield Advantage | +0.19%-0.20% | - |
For a $100,000 bond allocation, this yield difference translates to an extra $190–$200 per year in income when reinvested. This small advantage not only boosts current income but also lays the groundwork for better long-term growth.
Impact on Long-Term Portfolio Growth
SCHZ's slightly higher dividend yield can have a meaningful impact over time, especially for investors reinvesting their bond distributions. The additional yield helps fuel compounding returns, which can significantly grow a portfolio over the years. For those prioritizing income, SCHZ's higher yield also provides more immediate cash flow, which can help maintain the portfolio's sustainability over the long haul.

Costs, Trading, and Tax Considerations
When examining costs and trading, the differences in fees and liquidity between SCHZ and AGG can have a notable impact on investment decisions.
Expense Ratios and Trading Costs
Both SCHZ and AGG come with an identical expense ratio of 0.03%, which translates to about $3 annually for every $10,000 invested. However, trading costs set these two ETFs apart. AGG benefits from significantly higher liquidity, as reflected in its $133.56 billion AUM and trading volumes that are roughly five times higher than SCHZ. This increased liquidity results in tighter bid-ask spreads and smoother trade execution, particularly important for investors making larger trades.
| Trading Metric | SCHZ | AGG |
|---|---|---|
| Assets Under Management | $9.15 billion | $133.56 billion |
| 1-Month Average Daily Volume | 1,389,622 | 7,293,813 |
| 3-Month Average Daily Volume | 1,382,171 | 8,037,780 |
| Average Daily Dollar Volume | – | ~$709.4 million |
These trading characteristics tie back to earlier performance considerations, emphasizing the need to choose an ETF that fits your trading style and volume requirements.
Which ETF Fits Your Investment Strategy
When deciding between these ETFs, your investment style plays a big role in determining which one aligns best with your portfolio's needs. AGG stands out with its larger asset base and higher trading volume, offering better liquidity - an advantage for those who trade frequently. Here's how each ETF fits different investment approaches.
For Long-Term, Buy-and-Hold Investors
If you're a buy-and-hold investor, the liquidity differences between AGG and SCHZ are less of a concern. Both funds provide solid exposure to the U.S. bond market, making either a suitable choice as part of a diversified portfolio. Since trades are infrequent in this strategy, the choice boils down to your preference for fund management style or other minor differences.
For Active Traders and High Liquidity Needs
Active traders and investors dealing with large volumes will likely benefit more from AGG. Its higher assets under management and trading volume contribute to tighter bid-ask spreads and smoother trade execution. These features are especially helpful in reducing trading costs and mitigating market impact during volatile periods.
In short, SCHZ works well as a steady, long-term core holding, while AGG is better suited for those who prioritize liquidity and frequent trading efficiency.

Key Takeaways for Bond ETF Investors
When deciding between SCHZ and AGG, the differences are more about nuances than major contrasts. The standout distinction is in fund size and liquidity. AGG holds a commanding $133.56 billion in assets, compared to SCHZ's $9.08 billion - a reflection of AGG's earlier launch in September 2003, whereas SCHZ debuted in July 2011.
Looking at income metrics, SCHZ edges out AGG with a slightly higher dividend yield (4.01% vs. 3.81%). However, since both ETFs track the same broad index, their performance tends to move in close correlation, especially under typical market conditions.
For long-term, buy-and-hold investors, either fund can serve effectively. On the other hand, active traders might lean toward AGG due to its greater liquidity. The key is to align your choice with your overall portfolio strategy, rather than focusing solely on minor differences like a 0.20% yield variation.
What matters more is how these ETFs fit within your tax-advantaged accounts and broader financial plan. By focusing on your complete portfolio strategy and leveraging tools to analyze your asset mix, you can make these small differences work strategically in achieving your long-term goals.
FAQs
How do SCHZ and AGG differ, and what should I consider for my investment strategy?
SCHZ (Schwab U.S. Aggregate Bond ETF) and AGG (iShares Core U.S. Aggregate Bond ETF) differ in a few key areas that could impact your investment choices.
AGG, managed by BlackRock, boasts a much larger asset base of $129 billion, compared to SCHZ, issued by Charles Schwab, which holds $8.77 billion. AGG also has a longer history, having launched in September 2003, while SCHZ entered the market later, in July 2011. Despite these contrasts, both ETFs share an impressively low expense ratio of 0.03%, making them attractive for cost-conscious investors.
In terms of returns, SCHZ edges out AGG with a slightly higher dividend yield of 3.99%, compared to AGG's 3.80%. This might make SCHZ a better fit for those prioritizing income generation. On the other hand, AGG’s larger size and established track record could appeal to investors looking for a more seasoned option. Weigh these factors against your financial objectives and portfolio strategy to determine which ETF suits your needs best.
How does AGG’s liquidity make it more appealing to active traders compared to SCHZ?
AGG, the iShares Core U.S. Aggregate Bond ETF, typically provides better liquidity compared to SCHZ, the Schwab U.S. Aggregate Bond ETF. This means AGG often features tighter bid-ask spreads and higher daily trading volumes. For active traders, this can make buying and selling faster and more cost-effective, with less chance of influencing the market price.
For those who trade frequently or handle large transactions, AGG’s higher liquidity can offer greater flexibility and smoother execution. On the other hand, SCHZ may appeal more to long-term investors focused on a buy-and-hold approach, where liquidity concerns are less pressing.
When might SCHZ's slightly higher dividend yield benefit a long-term investor?
SCHZ offers a modestly higher dividend yield, which can appeal to long-term investors focused on generating income within their portfolio. Over time, reinvesting these dividends could amplify total returns, particularly for those with a long-term investment outlook.
This fund may also suit investors looking for consistent cash flow to meet financial objectives, such as retirement income, while still maintaining diversified exposure to the U.S. bond market. That said, it’s important to balance this advantage against considerations like expense ratios and how the fund aligns with your overall investment strategy.
