Causal Effect
A surprise cut still carries an inverted causal effect — signaling underlying economic weakness — but with conditions now LOOSE autonomously, a cut has more to disrupt. The causal delta widened as HY starting conditions improved but signaling risk was amplified by the 'why are they cutting if conditions are fine?' problem.
Why This Matters
Tests whether a rate cut can prevent credit stress from materializing. HY spreads compressed from 327bp (March) back to 287bp in April — the 350bp stress threshold is now 63bp away (vs. 23bp in March). Financial conditions reverted from NEUTRAL to LOOSE autonomously. The inverted-causal-effect concern from January and March remains: a surprise cut may still signal underlying weakness, but the cushion against breaching 350bp is now much larger. Credit markets are not pricing distress; the question is whether a signal-driven repricing could push spreads 63bp+ higher in a single month.
