TLT vs IEF: Head-to-Head Comparison

Side-by-Side Comparison

Key Differences Between TLT and IEF

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.

IEF (iShares 7-10 Year Treasury Bond ETF) is a intermediate treasury fund managed by BlackRock. IEF tracks the ICE U.S. Treasury 7-10 Year Bond Index, providing exposure to intermediate-maturity U.S. government bonds. These bonds offer a balance between the higher yields of long-term bonds and the stability of short-term bonds, sitting in the middle of the yield curve. IEF is widely used as a portfolio diversifier because intermediate Treasuries tend to rise in value when stocks fall sharply.

The most notable differences are in fees (0.15% vs 0.15%), number of holdings (42 vs 15), and 5-year returns (-5.20% vs -0.50%).
