The Vanguard Intermediate-Term Corporate Bond ETF (NASDAQ:VCIT) offers higher yields through corporate credit, while the iShares 3-7 Year Treasury Bond ETF (NASDAQ:IEI) prioritizes lower volatility and government backing.
Investors seeking fixed-income exposure often weigh the stability of government debt against the potentially higher yields of corporate bonds. Both funds target the intermediate portion of the maturity curve, but they differ significantly in credit risk, duration, and cost. This comparison examines how these characteristics impact total returns and portfolio volatility.
Beta measures price volatility relative to the S&P 500; beta is calculated from five-year monthly returns. The 1-yr return represents total return over the trailing 12 months. Dividend yield is the trailing-12-month distribution yield.
The Vanguard fund is notably more affordable with a 0.03% expense ratio compared to 0.15% for the iShares fund. This cost advantage, combined with the yield premium of corporate credit, leads to a higher overall payout. Investors earn a 1.19% yield advantage with VCIT, though this comes with the added risk of corporate debt.
The iShares 3-7 Year Treasury Bond ETF (IEI) replicates the performance of an index composed of U.S. Treasury securities with remaining maturities between three and seven years. It holds 83 government-backed bonds, which historically offer lower volatility than corporate debt. The portfolio consists primarily of intermediate-term Treasury notes. The fund was launched in 2007. The iShares 3-7 Year Treasury Bond ETF has paid $4.28 per share over the trailing 12 months, which, at its recent ~$117 share price, yields 3.70%.
The Vanguard Intermediate-Term Corporate Bond ETF (VCIT) tracks the Bloomberg U.S. 5-10 Year Corporate Bond Index, focusing on investment-grade debt issued by industrial, utility, and financial companies. It is more broadly diversified with 343 holdings, and its largest positions are individual corporate issues. This focus on corporate credit typically results in higher sensitivity to economic cycles than government-backed securities. The fund was launched in 2009. The Vanguard Intermediate-Term Corporate Bond ETF has paid $3.96 per share over the trailing 12 months, which, at its recent ~$82 share price, yields 4.90%.

While the Vanguard Intermediate-Term Corporate Bond ETF (VCIT) and the iShares 3-7 Year Treasury Bond ETF (IEI) are both fixed-income exchange-traded funds (ETFs), they differ in many key respects. Those seeking fixed-income exposure would be wise to consider both funds, but should gain a solid understanding of how each operates before selecting one over the other.
Let's start with Vanguard Intermediate-Term Corporate Bond ETF (VCIT). This fund focuses on corporate credit, meaning it holds corporate bonds issued by many iconic companies that investors already know. Top holdings include bonds issued by Amazon, Boeing, and Pfizer. These companies issue bonds to finance their operations, lower the cost of capital, or to fund mergers or acquisitions. While many of the bonds held by VCIT are issued by companies with very solid balance sheets, corporate bonds do carry credit risk—the potential that the issuer will delay, restructure, or default on its payments. This makes corporate bonds a slightly more risky asset class than, say, Treasury bonds, which are backed by the full faith and credit of the U.S. government. As for performance, VCIT has delivered a total return of 31% over the last 10 years, equating to a compound annual growth rate (CAGR) of 2.7%. Its rock-bottom expense ratio of 0.03% is among the lowest in the fixed-income ETF universe.
Then, there's IEI. This fund holds <a href="https://www.fool.com/investing/how-to-invest/etfs/treasury-bond-etfs/?utm_source=yahoo-host-full&utm_medium=feed&utm_campaign=article&referring_guid=2a8da2a5-7ebb-4374-bfb4-b421b356e0e4">U.S. Treasury bonds</a>. As such, it carries less credit risk than VCIT. However, there's a trade-off. Since Treasuries are inherently more likely to be repaid, they often yield less than corporate issues. This is reflected in the fund's dividend yield. IEI's current dividend yield is around 3.7%, while VCIT yields around 4.9%. Turning to performance, IEI has generated a total return of 13% over the last 10 years, with a CAGR of 1.2%. Last, IEI's expense ratio of 0.15% is affordable, but not as low as VCIT's.
In summary, VCIT is likely to be the choice for many investors seeking fixed-income exposure. It provides a solid mix of yield, risk, and low costs that will fit most investors' needs.

Four leading AI models discuss this article
"VCIT's yield and cost advantages are real but insufficient compensation for elevated credit risk that the article underplays in a late-cycle environment."
The article pushes VCIT (Vanguard Intermediate-Term Corporate Bond ETF) over IEI (iShares 3-7 Year Treasury Bond ETF) citing a 1.19% yield edge, 31% vs 13% 10-year total return, and rock-bottom 0.03% expense ratio. While VCIT's 4.9% yield and investment-grade corporate exposure (Amazon, Boeing, Pfizer) look attractive in a soft-landing scenario, the piece glosses over credit-spread widening risk in any slowdown. IEI's government backing and lower duration volatility remain superior ballast if recession odds rise or inflation reaccelerates. The 2.7% CAGR for VCIT still lags CPI plus equities over the same decade; cost savings don't fully offset default or downgrade risk.
If the Fed cuts aggressively into a recession, corporate spreads could compress sharply, letting VCIT outperform IEI by 300-400bp in a single year and validating the article's conclusion.
"The yield premium of VCIT is a compensation for credit risk that may prove insufficient if economic growth decelerates and corporate spreads widen."
The article frames this as a simple choice between yield and safety, but it ignores the fundamental role of duration risk in the current interest rate environment. VCIT (Vanguard Intermediate-Term Corporate Bond ETF) carries significantly higher credit spread sensitivity; if we hit a 'soft landing' with slowing growth, corporate spreads will widen, potentially offsetting the 1.2% yield pickup over IEI (iShares 3-7 Year Treasury Bond ETF). Investors chasing the 4.9% yield in VCIT are essentially selling volatility protection. For those expecting a recession, the capital preservation offered by IEI’s Treasury backing is superior, making the 'yield advantage' of VCIT a potential trap if credit defaults tick up.
If the economy avoids a hard landing, the tightening of corporate spreads could lead to price appreciation in VCIT that significantly outperforms the stagnant, lower-yielding Treasury notes in IEI.
"VCIT's historical outperformance is a product of a one-time credit cycle (2009–2015), not a durable advantage, and duration risk is systematically underpriced in the article's recommendation."
The article's conclusion—that VCIT is 'likely the choice for most investors'—rests on a misleading comparison. VCIT's 2.7% CAGR over 10 years versus IEI's 1.2% conflates two separate periods: the post-2008 credit recovery (2009–2014, when corporate spreads compressed dramatically) with the current environment. The article omits duration risk entirely. VCIT tracks 5–10 year corporates; IEI tracks 3–7 year Treasuries. In a rising-rate scenario, VCIT's longer duration means steeper drawdowns despite higher current yield. The 120bp yield pickup doesn't compensate for that tail risk in a 2–3% terminal rate world.
If recession fears spike and the Fed cuts aggressively in 2026–2027, VCIT's corporate spread compression could deliver outsized capital gains that dwarf IEI's duration advantage, making the historical CAGR comparison actually predictive.
"In risk-adjusted terms, IEI's shorter duration and defensive government backing may outpace VCIT's higher yield when rates rise or credit spreads widen."
The article frames VCIT as the clear 'better buy' due to yield and low costs, but that narrative glosses over duration and credit risk. VCIT tracks 5-10 year corporate bonds, leaving it more exposed to rate shocks and widening credit spreads if the economy slows. In a downturn, defaults and liquidity stress can erode value, even with a higher trailing yield of 4.9% vs IEI's 3.7%. IEI's 3-7 year Treasuries offer shorter duration and a government backstop, acting as a defensive ballast when risk appetite collapses. The piece also uses trailing yields and 10-year performance that may not reflect forward risk/return. Tactical balance matters.
Alternatively, if rates stabilize or fall and credit spreads tighten, VCIT’s yield premium could translate into meaningful carry and price gains, offsetting the extra risk. In a benign default environment, the diversification benefit of corporates may still beat Treasuries over the horizon.
"Lower-for-longer rates would amplify VCIT's duration advantage far more than its credit risk in a soft-landing baseline."
All three panelists fixate on recession-driven spread widening hurting VCIT, yet none flags the opposite convexity: if 2025 CPI prints sub-2% consistently, the Fed's terminal rate drops below 3%, triggering parallel duration gains that favor VCIT's longer 6.8yr effective duration over IEI's 4.2yr by an extra 150bp price upside before credit even moves.
"Liquidity risk and corporate supply dynamics are being overlooked in favor of purely duration-based analysis."
Grok is right on duration, but everyone is ignoring the liquidity premium. VCIT isn't just a duration play; it’s an institutional credit bet. In a 'soft landing' or 'no landing' scenario, the real risk isn't just duration—it's the potential for corporate bond supply to overwhelm demand if firms front-load issuance to lock in current rates. IEI remains the only true hedge against a liquidity crunch, which is a far more immediate threat than CPI-driven duration gains.
"Corporate issuance timing is a lagging indicator of spread widening, not a leading one; the liquidity risk cuts both ways depending on Fed action."
Gemini's liquidity premium argument is underexplored but overstated. Corporate bond supply surges happen *after* spreads widen, not before—issuance is endogenous to rate expectations. The real immediate threat is the inverse: if Fed cuts aggressively in 2025, *demand* for corporates spikes while supply dries up, compressing spreads faster than duration gains alone. IEI's liquidity advantage evaporates in that scenario. Grok's sub-2% CPI thesis is the actual near-term variable.
"Credit spread sensitivity and concentration risk in VCIT can erase its yield carry, making IEI a more reliable ballast."
Gemini, the liquidity premium angle is real but overstated as the main risk. The bigger issue is credit spread sensitivity and sector concentration in VCIT: even with a 4.9% yield, a mid-cycle spread widening or selective downgrades can erase price gains, especially if issuance accelerates and liquidity dries at the tail of a risk-off move. In that environment, IEI's shorter duration and Treasuries offer a more reliable ballast than VCIT's yield carry.
The panelists generally agree that while VCIT offers attractive yield and investment-grade exposure, its higher credit spread sensitivity and longer duration make it riskier than IEI in potential recession or rising-rate scenarios. However, they also acknowledge that VCIT could benefit from duration gains if inflation remains low.
