Best Bond Funds to Buy Now: BND vs FIGB for Core Fixed-Income Holdings

When building a diversified investment portfolio, choosing the right bond funds to buy now can significantly impact your long-term returns and portfolio stability. Two of the most popular options for investors seeking broad exposure to high-grade U.S. bonds are the Vanguard Total Bond Market ETF (NASDAQ: BND) and the Fidelity Investment Grade Bond ETF (NYSEMKT: FIGB). Both funds aim to serve as core fixed-income holdings, but they differ notably in cost structure, scale, and approach. This comprehensive comparison examines the key factors that should guide your decision when selecting among the best bond funds available today.

Cost Comparison: Which Bond Fund Offers Better Value

When evaluating bond funds to buy, fees should be a primary consideration since they directly reduce your returns over time. The expense ratio tells an important story about these two funds.

Vanguard’s BND charges just 0.03% annually—an exceptionally low cost that reflects Vanguard’s commitment to fee efficiency. In comparison, Fidelity’s FIGB carries a 0.36% expense ratio, making it twelve times more expensive. For an investor with $100,000 invested, this difference amounts to just $30 per year with BND versus $360 annually with FIGB. Over decades, this cost differential compounds significantly in BND’s favor.

Beyond pure fee structure, asset under management (AUM) matters for liquidity and fund stability. BND manages an enormous $389.22 billion in assets, while FIGB manages $423.78 million—representing roughly 1,000 times less capital. This massive scale advantage for BND enhances trading liquidity and reduces the risk of unexpected fund closures or restructuring.

Interestingly, despite BND’s lower yield percentage of 3.9% compared to FIGB’s 4.07%, BND actually delivers a higher absolute dividend payout. This occurs because BND’s per-share price is approximately $30 higher than FIGB’s, making the total income distribution more substantial in dollar terms for equivalent investment amounts.

Performance Metrics: How These Bond Funds Stack Up

When selecting among the best bond funds to buy, recent performance provides useful context, though past returns don’t guarantee future results. As of early 2026, BND showed a one-year total return of 4.19%, while FIGB returned 4.13%—essentially equivalent performance. Both funds exhibited minimal price volatility relative to broader markets, with beta readings of 0.27 (BND) and 0.28 (FIGB), reflecting the relatively stable nature of investment-grade bonds compared to equities.

Risk assessment reveals similar downside protection. Over the past four years, BND experienced a maximum drawdown of -14.37%, while FIGB’s maximum drawdown reached -15.02%. This slight difference suggests BND’s portfolio composition provides marginally better cushioning during market corrections, though both funds demonstrated reasonable resilience during fixed-income volatility.

Portfolio Holdings: Diversification and Risk Profile

Understanding what’s inside these bond funds to buy is essential for matching them to your investment needs. BND has operated for nearly two decades as a comprehensive tracker of the broad U.S. investment-grade bond market. Its portfolio comprises approximately 15,000 individual securities, providing exceptional diversification across multiple bond categories: U.S. government bonds, mortgage-backed securities, and investment-grade corporate debt.

FIGB represents a newer entrant to the bond ETF landscape, having launched less than five years ago. While it holds considerably fewer securities (735 positions), it still maintains broad exposure across the fixed-income sector. The fund’s smaller size should not be interpreted as inferior diversification—rather, it reflects a more concentrated approach to achieving similar market exposure.

A meaningful distinction emerges in credit quality allocation. BND maintains a slightly higher percentage of ultra-safe holdings, including U.S. government bonds and AAA-rated securities, compared to FIGB. Conversely, FIGB carries a higher proportion of lower-rated investment-grade bonds. This positioning means FIGB theoretically offers greater price appreciation potential during risk-on market environments, though it also introduces slightly elevated credit risk during economic downturns.

Making Your Choice: A Roadmap for Bond Fund Investors

For most investors seeking the best bond funds to buy now, BND emerges as the more compelling choice across several dimensions. Its dramatically lower fees provide superior value over multi-decade holding periods. The substantially larger asset base ensures superior trading liquidity. The slightly higher government bond allocation offers marginally greater safety for conservative investors. Performance has proven essentially equivalent, making cost efficiency the decisive factor.

However, FIGB shouldn’t be dismissed entirely. Its relative youth in the market potentially offers greater operational scalability and the opportunity to benefit from future asset accumulation. Additionally, for investors with higher risk tolerance seeking modest price appreciation upside, FIGB’s tilt toward lower-rated bonds might prove advantageous during extended bull markets.

A critical caveat applies to both options: bond ETFs grow significantly more slowly than stock ETFs. Historical data demonstrates that investors should not anticipate triple-digit annual returns from any bond fund. These vehicles function best as stability anchors within diversified portfolios, not as vehicles for aggressive wealth building. When properly utilized alongside equity holdings, either BND or FIGB can effectively fulfill this stabilizing role within a well-constructed investment strategy.

The choice between these bond funds ultimately depends on your specific circumstances—but for cost-conscious investors seeking broad, liquid exposure to investment-grade U.S. bonds, BND’s compelling fee advantage and institutional-scale asset base make it difficult to justify selecting FIGB, unless you have particular conviction about FIGB’s future growth trajectory or specific portfolio construction needs that its slightly different holdings composition addresses.
