The Fed cut. Daily yields still rose.

+5 bp10-year daily yield change

A half-point policy cut did not translate into lower daily Treasury par yields. This case challenges a simple “cut means yields fall” rule.

Inspect case and sources

Another policy cut. Higher daily Treasury yields.

+10 bp10-year daily yield change

The Fed cut the policy target by 0.25 percentage point to 4.25–4.50%. Beth Hammack dissented, preferring no change. Release at 14:00 EST. Daily observations describe the day, not an isolated announcement effect.

Inspect case and sources

A quarter-point cut accompanied lower daily yields.

−11 bp10-year daily yield change

The Fed reduced its policy target by 0.25 percentage point to 4.50–4.75%. Release at 14:00 EST. Daily observations describe the day, not an isolated announcement effect.

Inspect case and sources

−19 bp10-year daily yield change

The July jobs release reported slower hiring and higher unemployment. Daily yields declined across the 2-year and 10-year curve.

Inspect case and sources

The Fed noted inflation progress. Both tenors fell.

−6 bp10-year daily yield change

The Fed held the policy target at 5.25–5.50%, noted further progress on inflation, and said it was attentive to risks to both sides of its dual mandate. Release at 14:00 EDT. Daily observations describe the day, not an isolated announcement effect.

Inspect case and sources

Two announcements. One daily yield decline.

−8 bp10-year daily yield change

Inspect case and sources

The Fed held rates and slowed planned Treasury runoff.

−6 bp10-year daily yield change

The Fed held the policy target at 5.25–5.50% and announced a reduction in the monthly Treasury redemption cap from $60 billion to $25 billion beginning in June. Release at 14:00 EDT. Daily observations describe the day, not an isolated announcement effect.

Inspect case and sources

March inflation persisted. Daily yields rose.

+19 bp10-year daily yield change

Inspect case and sources

An unchanged target. A larger move at two years.

−3 bp10-year daily yield change

The Fed held the policy target at 5.25–5.50% and required greater confidence in inflation moving sustainably toward 2% before a reduction. Release at 14:00 EDT. Daily observations describe the day, not an isolated announcement effect.

Inspect case and sources

The Fed held. Daily yields declined.

−7 bp10-year daily yield change
