Mexico’s central bank unanimously kept its benchmark interest rate at 6.50% on September 24, extending a pause that began after policymakers completed an easing cycle earlier this year. The decision itself matched expectations, but the accompanying statement changed the guidance investors use to judge what could happen next. Banco de México removed language from its previous communiqué indicating that the policy rate would remain at its current level for an extended period, leaving officials more room to respond when the governing board meets again in November.
The shift came as inflation continued to run above the bank’s 3% target. Headline consumer-price inflation was reported at 3.42%, while the core measure, which strips out some volatile components and is often watched for persistent pressure, stood at 3.79%. Banxico said it still expects inflation to converge to target in the fourth quarter of 2027. That distant return path helps explain why officials kept policy restrictive even as they softened the language around how long the current rate must remain in place. Officials also noted that risks to the inflation outlook remain tilted to the upside, reinforcing the need for caution.
Policymakers are also weighing a less synchronized international backdrop. The U.S. Federal Reserve had raised its policy rate, yet Banxico chose not to follow with an increase, underscoring that Mexican officials are setting policy around domestic inflation and economic conditions rather than mechanically matching every move in Washington. The revised statement did not promise a cut, however. It emphasized that the board will consider inflation’s behavior, its determinants and expectations, preserving the option to hold again if price pressures prove stubborn.
Polymarket traders put the probability of no change after Banxico’s November meeting at about 92.5% in the latest snapshot, up roughly 18 percentage points over one day. The broader event had drawn about $3,486 in activity during the previous 24 hours and held roughly $16,020 in liquidity. Those figures show a strong current consensus but relatively modest participation, so they should be read as a live expectation rather than a substitute for official guidance, economic data or the governing board’s eventual vote.
The next several inflation releases will determine whether the wording change becomes a policy move or remains only additional flexibility. A continued decline in core inflation would give the board more room to resume easing, while renewed pressure in food, services or the peso could reinforce the case for another hold. Banxico’s September decision therefore leaves November unusually clear in one sense and open in another: officials did not change the rate, but they deliberately stopped telling the public to assume that the pause must be prolonged. The November announcement will show whether that was preparation for action or prudent language in an uncertain environment.
