BND vs TLT: Head-to-Head Comparison

Side-by-Side Comparison

Key Differences Between BND and TLT

BND (Vanguard Total Bond Market ETF) is a u.s. intermediate-term bond fund managed by Vanguard. BND provides exposure to the entire U.S. investment-grade bond market, including government, corporate, and mortgage-backed bonds. Bonds generally provide stability and income to a portfolio, acting as a cushion when stocks decline. Beginners often add BND to their portfolio to reduce overall volatility and provide steady income, with the typical rule of thumb being to hold your age in bonds as a percentage of your portfolio.

TLT (iShares 20+ Year Treasury Bond ETF) is a long-term u.s. treasury fund managed by BlackRock. TLT invests in U.S. Treasury bonds with maturities of 20 years or more, making it highly sensitive to changes in long-term interest rates. When rates fall, TLT can deliver stock-like returns, but when rates rise, it can suffer significant losses. Beginners should understand that TLT is much more volatile than short-term bond funds, but it can serve as powerful portfolio insurance during stock market crashes.

The most notable differences are in fees (0.03% vs 0.15%), number of holdings (11,286 vs 42), and 5-year returns (-0.50% vs -5.20%).
