The review continues: 
USMCA faces uncertain future
By Pete Goldin, AJOT
The United States–Mexico–
Canada Agreement (USMCA) 
required the USMCA Free 
Trade Commission to conduct 
a joint review of the agree-
ment on July 1, 2026. The out-
come of the meeting is that the 
US did not agree to renew the 
USMCA in its current form. 
The US Trade Representa-
tive (USTR) reports that the 
US will continue to engage 
with Mexico and Canada to 
address the USMCA’s short-
comings, as well as US trade 
deficits with these countries. 
This includes a third round of 
bilateral negotiations between 
US and Mexico on July 20.
The US decision trig-
gered a cycle of annual 
joint reviews over the next 
10 years, while the original 
16-year USMCA plan keeps 
the treaty fully operational 
until July 1, 2036. However, 
any of the three countries 
can still withdraw from the 
agreement if they provide 
six-month’s notice.
Victory Or Setback?
“July 1 did not settle 
USMCA’s future. It opened 
the next phase of the review,” 
explains Blake Harden, Man-
aging 
Director, 
Washing-
ton Council, Ernst & Young 
(EY). “The agreement did not 
expire, nor was it renewed for 
another 16 years. It remains in 
force through 2036, meaning 
there is no immediate disrup-
tion to North American trade.” 
Harden continues, “This 
is neither a clear victory nor a 
setback. Rather, it signals that 
the parties are taking addi-
tional time to work through 
complex issues. The United 
States and Mexico have 
begun formal review discus-
sions, while the United States 
and Canada continue to 
engage more informally. That 
continued engagement is a 
constructive sign, although a 
trilateral outcome will ulti-
mately be needed to achieve 
many of the administration’s 
broader objectives.”
Harden adds, “For busi-
nesses, the key issue moving 
forward is the uncertainty 
surrounding the future rules 
governing preferential treat-
ment, investment decisions, 
and market access as negoti-
ations continue.”
William Alan Reinsch, 
Senior Adviser and Econom-
ics Program and Scholl Chair 
in 
International 
Business 
at Center for Strategic and 
International Studies (CSIS) 
says that USMCA uncertainty 
could be intentional because 
it is expected to drive compa-
nies to invest in the US rather 
than Canada or Mexico, but 
he believes the more likely 
outcome is most companies 
putting plans on hold. 
“If companies don’t know 
what tariffs or other regulatory 
requirements, they will face in 
six months or a year, they will 
usually wait until they have 
greater confidence about the 
future,” says Reinsch. “Even 
companies already located in 
the United States that have 
substantial exports to Mexico 
or Canada will hold off on 
new US investment if they 
don’t know what their future 
tariff liabilities will be.”
“While some custom-
ers are taking a wait-and-see 
approach to the USMCA 
review, their focus is on 
building supply chains that 
can quickly adapt to chang-
ing conditions and avoid
