Historical education / 2024-06-12
Two announcements. One daily yield decline.
May CPI was flat month over month, then the Fed held its policy range. Daily Treasury yields fell; that alone cannot separate the two announcements.
Confidence not assessed. Daily association, not proof of causation.

What the daily curve records
U.S. Treasury nominal par yields, in percent. A yield change is not a bond return.

Interpretation / editorial hypotheses
Mechanism & alternatives
These explanations are proposed from the cited facts, not statements made by the sources.
Possible mechanism
The flat CPI reading could have reduced inflation or expected policy-rate pressure, consistent with lower yields. This is an interpretation, not a measured attribution.
Alternatives
The afternoon Fed communication, positioning or changing term premia could also affect the daily curve. A same-day observation cannot isolate the morning CPI effect.
What would challenge the explanation?
Compare licensed intraday observations around each announcement. A decline outside the CPI window would weaken a CPI-led explanation; daily endpoints cannot run that test.
No survey consensus is stored, so no inflation surprise is quantified. No intraday effect, abnormal return or causal share is estimated.
