About this brief
Night briefs are SignalPop's "what actually happened today" pass — the slot where the day's reporting has had time to settle and the genuine news has separated from the false starts. We re-rank everything from scratch at this point: stories that broke at 9 a.m. and then got corrected, retracted, or expanded by 6 p.m. show up differently here than they did in the morning brief. The tone is slightly drier; the cuts are sharper. If you only read one brief a day, the night one is the most complete read of what mattered — though it lands too late for most newsletter schedules, which is why we email the noon edition instead.

The Treasury market is in a rout. Traders are pricing in rate increases. The Federal Reserve's reassuring language about patience is not reassuring the bond market. Tough talk about inflation may be what the rout is demanding.

Editorial note
One last thing about how SignalPop is built, since the night brief is the slot most readers reach via search. SignalPop is independently operated, monetized by display advertising and the occasional sponsorship, and run from a single laptop with a small set of AI providers doing the curation and summarization. The editorial standards live at /about/methodology; the privacy policy at /privacy explains exactly what we collect (very little) and who else can see it (almost no one). If anything on this page reads as wrong, off-tone, or just bad — every page has a contact form, and the address is hello@signal-pop.com. Sleep well; tomorrow's morning brief publishes around 7 a.m. ET.
