The iShares iBoxx $ Investment Grade Corporate Bond ETF (LQD) outperformed the iShares 20+ Year Treasury Bond ETF (TLT) over the last 12 months [1].

This performance gap highlights the differing risk profiles of corporate bonds versus long-term government debt during a period of market volatility. Investors choosing between the two BlackRock-managed funds must weigh the stability of Treasury bonds against the potential for higher returns in the corporate sector.

Both ETFs currently offer identical yields of 4.6% [2]. However, their total returns for the trailing 12-month period ending in 2026 diverge significantly. LQD recorded a total return of 4.2% [2], while TLT returned 2.5% [2].

Beyond raw returns, LQD has demonstrated lower volatility than TLT [2]. This stability is attributed to LQD's broader corporate-bond holdings, which offer a different risk-reward balance than the long-term Treasury exposure found in TLT. Additionally, the expense ratio for LQD is slightly lower than that of TLT [3].

Long-term Treasury bonds have faced steeper challenges in recent years. TLT has seen a drawdown of approximately 48% since 2020 [4]. This decline underscores the sensitivity of long-duration bonds to interest rate shifts, a factor that has weighed more heavily on TLT than on the corporate-focused LQD.

"Investors can purchase low‑cost bond ETFs in just about any flavor you can imagine," Steve Laipply said in a June interview with Bloomberg.

Both funds trade on the NYSE Arca, providing investors with liquid access to these distinct segments of the U.S. fixed-income market [1].

“LQD recorded a total return of 4.2%, while TLT returned 2.5%.”

The data suggests that while yield parity exists between these two instruments, the underlying assets create vastly different outcomes. LQD's superior total return and lower volatility indicate that investment-grade corporate debt provided a more efficient hedge and growth vehicle than long-term government bonds over the past year. The significant long-term drawdown of TLT reflects the ongoing volatility associated with long-duration Treasury assets in a fluctuating rate environment.
