High Yield Credit (HYG)

HYG is the iShares iBoxx High Yield Corporate Bond ETF, the largest and most-traded ETF in below-investment-grade corporate credit. It holds roughly 1,200 bonds rated BB+ and below ("junk"), with weighted-average duration near 3.5 years and a portfolio yield in the high single digits. HYG is the standard liquid expression of risk in credit markets and trades roughly $1.5 billion average daily volume.

Why it matters: high-yield spreads (the option-adjusted spread, OAS, of HY over Treasuries) lead equity drawdowns by roughly two to four weeks. When OAS blows out above 800bp, recessions follow with high reliability. When OAS compresses below 350bp, equities are typically late-cycle. HYG is also a sentiment proxy because retail flows in and out of the fund are larger as a percentage of AUM than in IG credit, which means HYG can disconnect from underlying fair value during stress.

HYG closed $80.48 on April 26, 2026 with HY OAS at 2.84% (roughly 284bp), well below the 800bp recession threshold and tighter than the post-2021 average. The TTM return is approximately +10%, with 2024 +7.97% and 2025 +8.60%, both healthy single-digit-plus-coupon years.

The default rate sits at 2.5% TTM through December 2025, materially below the 13% peak of 2008-09 and the 5.5% 2020 print. Spreads this tight are inconsistent with a recession-imminent narrative; they suggest that either the market is right that the cycle extends or that complacency has reached the point where the next risk-off is sharp. Watch HYG-LQD relative performance, when HY underperforms IG by 2-3% in a month, that is typically the early warning before a broader risk-off.

HYG OAS history: peaks at 2,100bp in December 2008, 1,100bp in March 2020 (the fastest widening on record at 23 business days), 600bp in 2015-2016 energy stress, and 600bp in October 2022. Tights below 300bp in 2014, 2017, and 2021 marked late-cycle complacency. HYG total return is dominated by spread direction: a 100bp OAS widening produces roughly -3.5% price move on top of any rate move.

First, the HY OAS level. Below 350bp is late-cycle complacency; above 600bp is stress; above 800bp historically signals or follows recession.

Second, energy-sector weight (~14% of HY). Oil moves below $60 push energy issuers toward distress and widen the index OAS even when broad credit is stable.

Third, the HYG-LQD relative spread. Sustained HYG underperformance front-runs equity drawdowns by 2-4 weeks; this is the cleanest cross-asset stress signal.
