Vanguard Long-Term Corporate Bond Index Fund Institutional Shares VLCIX

Vanguard Long-Term Corporate Bond ETF offers diversified exposure to the long-maturity corporate bond market at a rock-bottom price, making it a compelling choice in the long-term bond Morningstar Category.

The fund tracks the Bloomberg US 10+ Year Corporate Bond Index, which targets US-dollar-denominated, investment-grade corporate bonds with at least 10 years remaining to maturity. Eligible bonds must have fixed-rate coupons, ensuring they have predictable yields. Once selected, constituents are weighted by market value. This approach helps diversify issuer and issue risk while accurately mirroring the long-dated corporate universe.

The portfolio’s narrow mandate makes it an outlier in the long-term bond category. While the typical peer invests a little more than half its assets outside of corporate bonds, this strategy focuses on them solely. As a result, it collects over 40 percentage points more corporate exposure than the category average.

This tilt means a riskier credit profile. The fund allocates about 44% of its assets to BBB rated bonds and most of the remainder to A rated issues. Category peers typically hold around 30% in AAA and AA rated securities, compared with just 10% here. This riskier credit posture benefits the fund when spreads tighten but introduces more downside risk during periods of credit market stress.

Performance has followed this expected pattern. The fund beat the category average by 78 basis points annualized over the past decade through February 2026, doing relatively better when spreads tightened and weaker when they widened. Shifting interest rates can also weigh on performance. The fund’s longer average duration than peers means it is more sensitive to rate movements. This held it back in 2022 when rates quickly rose.

Vanguard Long-Term Corporate Bond ETF earns an Above Average Process rating for effectively capturing the long-term corporate bond market.

The Bloomberg US 10+ Year Corporate Bond Index targets investment-grade corporate bonds maturing in 10 years or longer. Bonds must be denominated in US dollars and have a fixed-rate coupon. The index specifically seeks taxable debt securities issued by US and non-US industrial, utilities, and financials companies. Selected securities are weighted by their market value, which helps spread risk across issuers and individual issues.

The fund is a misfit in the long-term bond category. While the typical peer holds almost 20% of assets in government bonds and more than 10% in securitized debt, this portfolio leans entirely on corporates. Because of this, its near-100% corporate bond exposure is more than 40 percentage points greater than the category average.

The fund carries more credit risk than the typical category peer since corporates tend to be riskier than the government bonds or securitized debt more plentiful in competitor portfolios. It places roughly 44% of its assets in BBB rated bonds and allocates most of the rest to A rated issues, making this fund more than 30 percentage points overweight these tiers combined relative to the category average. Peers generally prefer the highest-quality rungs of the credit ladder because they include government and municipal bonds in their mandates. The typical category peer stashes around 30% of its portfolio in AAA and AA rated bonds, compared with just 10% here.

An average duration of around 1 year longer than peers means the fund carries more interest rate risk than most. A greater sensitivity to interest rate movements positions it to benefit more than its average peer when rates decline, but it will suffer proportionately more when rates rise.

Performance will diverge from peers with broader mandates since the fund represents a somewhat narrow part of the bond landscape. It still effectively captures the long-term investment-grade corporate bond segment, though, making it an easy choice for investors looking for such exposure.

Vanguard's fixed-income index team has a lot of advantages. It taps into a global network of portfolio managers, sector specialists, and trading desks to deliver accurate index tracking in the markets that it touches. It earns an Above Average People Pillar rating.

Experienced managers make up Vanguard’s team. They’re supported by a deep bench of talent that allows them to focus on portfolio construction and tracking performance. Each fund has a lead manager who collaborates with traders and sector specialists to ensure tracking performance stays within well-defined guardrails.

Specialization extends in many directions. ETF specialists help manage creation and redemption baskets, while a dedicated data team handles index changes and corporate actions. International specialists help manage portfolios in local markets outside of the US to keep costs down and tracking tight.

Many bonds aren’t available for trading, so index funds cannot hold every bond in an index. Despite that drawback, Vanguard’s team has continued to invest in new ways to improve the precision of its tracking efforts while keeping a lid on trading costs. It recently expanded its quantitative unit, which developed an optimization tool that incorporates traders' insights and liquidity data to improve tracking performance.

Vanguard maintains its High Parent Pillar rating as it continues to grow under new leadership.

CEO Salim Ramji has had a busy first year captaining Vanguard’s crew, and the ship remains pointed in the right direction. The firm made its largest round of fee cuts in early 2025, which came at an estimated cost of USD 350 million. It established a separate division dedicated to its advice and wealth management efforts, a sign that it wants to seriously compete within those lines of business. Asset growth has continued to be a huge success. Only BlackRock’s inflows rival the money Vanguard is taking in. Likewise, the number of clients it serves has more than doubled since 2015.

Despite that success, an ever-growing number of clients has presented a challenge: Vanguard can’t grow its services fast enough to keep up with demand. In some instances, it has had to curb certain services and capabilities or raise fees on others to cope, causing some loyal clients to criticize what they perceive as deteriorating services.

Vanguard has ambitions to bring its disruptive legacy to the bond market. It created roughly a dozen low-cost bond exchange-traded funds for US investors and several others abroad over the 12 months through June 2025. All have low fees in their respective categories, and the actively managed strategies align with Vanguard’s philosophy. They are relatively easy to understand and are conservatively managed.

Vanguard has another opportunity to prove that clients are still its priority. On the surface, its endeavor into the high-fee deal-making world of private assets alongside Wellington and Blackstone looks like a cultural mismatch. So far, the collaboration hasn’t produced anything that’s concerning.

The ETF share class beat its average category peer by 78 basis points annualized over the past decade through February 2026. It has historically outperformed during tightening credit conditions and underperformed when spreads widen since it takes on more credit risk than most. For example, the fund lagged the category average by 1.7 percentage points in 2022 when spreads quickly widened. However, 2023’s quick recovery, accompanied by tightening credit spreads, helped the fund beat the category average by 2.4 percentage points.

The fund’s longer average duration than its typical peer means that it is more sensitive to interest rate movements, contributing to its higher volatility and greater magnitude of out- or underperformance during periods of shifting rates.

Short-term relative performance will vary with shifting credit conditions and interest rate movements, but the fund’s riskier credit profile and low fee should continue to produce strong long-term returns.
