Fund data as of March 31, 2026
TLT has an expense ratio of 0.15 percent, which consists entirely of the management fee. The 30-day SEC yield as of March 31, 2026 was 4.84 percent. An ETF is a traded index fund that replicates the performance of a specific index and trades like a stock.
The weighted average maturity of bonds held in the fund was 25.79 years. The effective duration—a sensitivity measure for interest rate changes—was 15.33 years. This means: If interest rates rise by one percentage point, the fund value would theoretically fall by approximately 15.33 percent.
Interest rate risk and volatility
TLT exhibits an inverse correlation to interest rate movements. When interest rates rise, the fund value falls; when interest rates fall, it rises. This relationship stems from the fundamental mechanics of bond pricing.
The three-year standard deviation was 13.81 percent, reflecting the fund's volatility range. Equity beta was 0.70, indicating lower volatility intensity compared to the broad equity market.
Comparison with corporate bond ETF
An analysis by The Motley Fool on June 16, 2026 compared TLT with the iShares 10+ Year Investment Grade Corporate Bond ETF (IGLB). TLT offers pure exposure to long-term US Treasury bonds without the credit risk of corporates. IGLB, by contrast, offers lower costs and higher yields than TLT.
Investor profile
The fund is suitable for investors seeking exposure to long-term US Treasury bonds with maturities exceeding 20 years. The high duration of 15.33 years makes the fund highly sensitive to interest rate changes—a characteristic typical of long-term fixed-income fund investors.
BlackRock manages the ETF passively, meaning without active security selection. The low expense ratio of 0.15 percent aligns with the typical level for passively managed Treasury bond ETFs.
