Will HY corporate bond spreads exceed 350bp by October 2026?
The Condition
US blanket tariffs (Section 122 or successor authority) of at least 10% remain in effect on July 24, 2026
Our Ensemble Estimates
Given tariffs persist: Will HY corporate bond spreads exceed 350bp by October 2026?
Given tariffs expire: Will HY corporate bond spreads exceed 350bp by October 2026?
Causal Effect
Tariff persistence increases the probability of HY spreads exceeding 350bp by 12 percentage points. The primary channel is margin compression: firms absorbing 18-20pp of tariff costs will exhaust buffers by mid-2026, creating simultaneous margin and revenue pressure for overleveraged HY issuers. Tariff removal eliminates this channel entirely, making credit deterioration much less likely. However, even with persistent tariffs, 350bp remains unlikely (25%) given deeply accommodative financial conditions, declining defaults, and AI-driven risk appetite providing structural support.
Why This Matters
Tests whether persistent blanket tariffs eventually crack the currently benign credit environment. HY OAS stands at 288bp and has been compressing despite the trade policy regime, with NFCI at -0.568 (deeply accommodative). The analysis identified a key tension: credit stress is easing while absorption buffers are depleting. If tariffs persist and firms exhaust their ability to absorb costs through margin compression, overleveraged companies could face simultaneous margin and revenue pressure, triggering credit deterioration. The 350bp threshold represents a meaningful widening from current levels (~62bp) that would signal credit markets are repricing trade policy risk. The Section 122 expiration was flagged as the primary catalyst for potential spread widening.
Resolution Criteria
ICE BofA US High Yield Index Option-Adjusted Spread (FRED series BAMLH0A0HYM2) closes at or above 350 basis points on any trading day on or before October 31, 2026
Source Analysis
Financial conditions deeply accommodative (NFCI -0.568); HY spreads compressed 31bp in 3 months to 288bp; credit stress easing despite trade policy regime shift — but depleting absorption buffers may eventually translate to credit stress
