Also known as: IG Credit (LQD) (ETF_LQD, investment grade ETF) · 20Y+ Treasury ETF (long bonds, treasury ETF)
Why This Comparison Matters
LQD (iShares iBoxx Investment Grade Corporate Bond ETF) tracks roughly 2,800 USD-denominated investment-grade corporate bonds with current yield approximately 4.52 percent and duration approximately 8 years. TLT (iShares 20+ Year Treasury Bond ETF) tracks long-duration Treasuries with yield 4.49 percent and duration approximately 17 years. The pair isolates IG credit risk from pure duration. LQD outperformance signals tightening credit spreads, healthy corporate balance sheets, and risk-on rotation. TLT outperformance signals widening spreads, recession fears, or aggressive Fed cuts compressing the long end. The current LQD/TLT ratio of approximately 1.26 reflects compressed IG OAS (80 basis points, near 25-year tights) combined with elevated long-end term premium hurting TLT.
The April 2026 Configuration
LQD closes April 24, 2026 at $109.52 with current yield 4.52 percent and duration approximately 8 years. TLT closes at $87 with yield 4.49 percent and duration approximately 17 years. LQD/TLT ratio is therefore 1.26.
IG OAS sits at approximately 80 basis points, near 25-year tights and well below the long-run average of approximately 150 basis points. By rating tier: AAA OAS approximately 40 basis points, AA approximately 51 basis points, BBB approximately 100 basis points. LQD weights heavily toward A-rated and BBB-rated names (BBBs comprise roughly 50 percent of LQD by market value).
The combined reading: tight IG spreads + elevated long-end yields. Late-cycle expansion: corporate credit conditions benign (low default expectations) but long Treasury market pressured by term premium expansion. The configuration favors LQD modestly: moderate duration plus tight credit spreads delivers steadier performance than TLT, which absorbs the full impact of long-end yield moves.
How LQD and TLT Diverge
LQD and TLT have distinct drivers despite both being investment-grade bond ETFs. LQD blends moderate interest rate risk (8-year duration) with IG credit risk (default and downgrade expectations). TLT is pure interest rate risk (17-year duration) with no credit risk (Treasury default risk effectively zero).
The practical implication: LQD and TLT diverge during specific macro regimes. Risk-on/credit-tightening regimes: LQD outperforms TLT (IG spreads compress, supports LQD; long yields stable or rise on growth). Risk-off/recession-imminent regimes: TLT outperforms LQD (long yields compress on Fed cuts; IG spreads widen on default expectations).
Correlation between LQD and TLT averages 0.55-0.70 in normal conditions (higher than HYG-TLT due to LQD's lower credit risk content). During pure flight-to-safety correlation can flip negative briefly. During inflation-driven stress correlation rises to 0.75+ (both fall on rate rises). The 2022 anomaly: both fell together as rate rises hurt TLT more (50 percent peak-to-trough) and LQD (25 percent peak-to-trough).
LQD-vs-TLT as Credit-Cycle Indicator
LQD/TLT ratio captures IG credit cycle independent of pure duration. The ratio compresses when spreads widen and expands when spreads tighten. Three historical examples.

LQD price $109.52, TLT price $87, LQD/TLT ratio 1.26 (April 2026). LQD blends moderate duration with IG credit risk; TLT is pure long-duration with zero credit risk.
How do LQD and TLT diverge?+
Distinct drivers despite both being investment-grade bond ETFs. Risk-on/credit-tightening regimes: LQD outperforms (IG spreads compress; long yields stable/rise on growth). Risk-off/recession-imminent regimes: TLT outperforms (long yields compress on Fed cuts; IG spreads widen on default expectations). Correlation 0.55-0.70 normal conditions (higher than HYG-TLT due to LQD lower credit content). During pure flight-to-safety can flip negative briefly. During inflation-driven stress rises to 0.75+ (both fall on rate rises). 2022 anomaly: both fell together - LQD -25 percent, TLT -50 percent. LQD duration ~8 years vs TLT ~17 years explains relative duration sensitivity.
How is LQD-vs-TLT a credit-cycle indicator?+
Three historical examples. 2008-09 GFC: IG OAS spiked from 100 to 600 basis points peak. LQD -23 percent; TLT +37 percent. Ratio compression 44 percent. 2020 COVID: IG OAS spiked from 90 to 380 basis points peak. LQD -15 percent in 3 weeks; TLT +18 percent. Ratio compression 28 percent. Fed PMCCF/SMCCF March 23 2020 reversed compression within 6 weeks. 2022 hiking: IG OAS widened modestly (95 to 165 basis points). LQD -25 percent (mostly duration); TLT -50 percent. Ratio expanded as TLT fell more. April 2026 ratio 1.26 normal range. Compression below 1.10 warrants monitoring; below 1.00 signals IG credit stress.
