The US and Mexico do not have a signed USMCA-related trade agreement in hand at their September 28-29, 2026 meeting.
The wording, the opening probability, and the counter-signal below were fixed when this call was published. Updates revise the reading — never the record: the verdict is graded against the opening call.
The trajectory
The record since
The call stands as issued — no revisions.
What would overturn it
A joint US-Mexico statement or USTR/Economy Ministry announcement confirming a signed deal at or immediately following the September 28-29 session. A White House or Palacio Nacional readout describing a finalized, signed agreement on tariffs, autos, or steel/aluminum from that meeting would count against this.
The verdict
Hit Resolved 5 Oct 26.
No signed US-Mexico deal emerged; the fourth negotiating round slipped past Sept 28-29 and Mexican officials said it would likely come in October.

As logged at issue
The US and Mexico will likely not have a signed USMCA-related trade agreement in hand at their September 28-29 meeting, given how many separate tracks -- tariffs, autos, steel, agriculture, labor -- remain open at once -- unless this week's Trump-Sheinbaum call cleared more ground than the conflicting readouts suggest.
