Inflation-Adjusted Aggregate Bond ETF (AGG)

The iShares Core U.S. Aggregate Bond ETF (AGG) tracks the Bloomberg Barclays US Aggregate Bond Index, offering comprehensive exposure to US investment-grade government, corporate, and securitized bonds.

Fixed-income investments face unique challenges from inflation, as rising prices can significantly erode the real value of bond returns over time. This page adjusts the historical price of AGG for inflation, using the US Consumer Price Index, to reveal its real performance over time. Explore the interactive charts and tables below to compare nominal vs. inflation-adjusted data and discover its actual long-term performance.

Nominal prices are adjusted for stock splits and assume reinvestment of any dividends to reflect total return. Inflation-adjusted prices use March 2026 as the baseline (latest available CPI).

The current value of the iShares Core U.S. Aggregate Bond ETF is 98.96 (as of the close of Apr 29, 2026), 2.38% lower than the all-time high of 101.37 (Aug 4, 2020).

While the nominal high reached 101.37, the inflation-adjusted peak value was 128.9 on July 31, 2020.

Since September 29, 2003, the inflation-adjusted total return for the ETF has been 9.74%, which is equivalent to an annual growth rate of 0.41%.

In nominal values, the total return since this date has been 95.66%, or an annualized rate of 3.02%.

Inflation-Adjusted Values by Month

This data presents the ETF's end-of-month closing levels over time. Inflation-adjusted values express older levels in terms of roughly today's purchasing power using the latest CPI data, the same present-value method used by the US Inflation Calculator to compare dollar amounts across different years. The most recent entry will remain the same in both columns until the next CPI figures are published.

Returns from Investing in the iShares Core U.S. Aggregate Bond ETF

How much did an investment in the AGG ETF really grow each year after accounting for inflation? The following chart contains the inflation-adjusted real annual percentage returns.

Detailed Annual Returns (Adjusted vs. Nominal)

The table below shows the returns for the iShares Core U.S. Aggregate Bond ETF by year, both inflation-adjusted and nominal. You can sort any column by clicking on the header.

2023	2.22%	5.65%

Ishares Core U.s. Aggregate Bond Etf: Average Annualized Returns

Annualized returns show the average rate of growth per year, making it easier to compare performance across different time periods. While nominal returns indicate the headline growth, adjusting for inflation reveals the actual change in purchasing power.

This table presents both nominal and inflation-adjusted average annual returns for the iShares Core U.S. Aggregate Bond over various trailing periods ending March 31, 2026, offering a clearer view of long-term, real investment performance.

Period	Avg. Annual Return (Inflation-Adjusted)	Avg. Annual Return (Nominal)
Last 1 year	1.06%	4.35%
Last 3 years	0.53%	3.58%
Last 5 years	-4.04%	0.29%
Last 10 years	-1.63%	1.64%
Last 20 years	0.54%	3.1%

Real Returns of Investing in the iShares Core U.S. Aggregate Bond

The chart and table below show the nominal and inflation-adjusted value of a hypothetical $100 investment over various long-term historical periods, ending in September 2025.

The inflation-adjusted line, in green, represents the real increase in purchasing power for the initial investment. Observe the gap between both lines, which illustrates the cumulative effect of inflation over time.

Even over just five years, inflation takes a noticeable bite out of investments. Investing $100 in the iShares Core U.S. Aggregate Bond five years ago yielded an -0.68% nominal gain, but the real return (the actual increase in buying power) was -19.57%.

As investment periods get longer, the difference between reported nominal returns and the inflation-adjusted gains usually becomes much greater due to the compounding effect of inflation over time.

Investment Period	What $100 Grew To (Nominal)	Total Nominal Return (%)	Total Inflation-Adjusted Return (%)
Last 5 years Feb 2021 - Sep 2025	$99.32	-0.68%	-19.57%
Last 10 years Feb 2016 - Sep 2025	$117.58	17.58%	-14.16%
