Mexico Gets Three Decisive Numbers on a Single Day Next Week

Mexico’s central bank, its statistics agency and its finance ministry are about to collide on one Thursday. One of them has already placed a bet.

Banco de Mexico announces its rate decision on Thursday 24 September 2026, at 13:00 in Mexico City. The September inflation flash and the July activity index publish the same day.

The overnight target rate is 6.50%. It has been there since 7 May 2026.

This year’s path was short. A hold in February, a quarter-point cut in March, another in May, then two holds.

The easing cycle ended in May. The board has voted unanimously at both meetings since.

That matters more than the level. A board that split during the cuts is now voting five to nothing to wait.

The August statement said plainly that keeping the rate at its current level would be appropriate.

It also pushed the expected return to the 3.0% inflation target out to the final quarter of 2027.

August inflation, published on 9 September, came in at 3.26% over twelve months.

The monthly rise was 0.20%. A year earlier the annual figure had been 3.57%.

That looks like a problem solved. The core measure says otherwise, at 3.88%.

Core inflation strips out farm produce and energy, so it is the part policy can actually reach.

Analysts surveyed by the central bank expect headline inflation to end 2026 at 3.90%, above where it sits now.

In other words, the market expects the number to get worse before the target is reached.

Finance Secretary Edgar Amador Zamora delivered the 2027 package to deputies on the evening of 8 September.

Total net spending is set at 10.636 trillion pesos, about US$620 billion.

Budget revenue is 9.157 trillion pesos, roughly US$534 billion, with tax collection at a record 15.9% of output.

Growth is assumed at 1.5% to 2.5%, with a central estimate near 2.0%. The deficit measure falls to 3.9% from 4.1%.

And the package assumes a policy rate of 6.0%. Banxico is at 6.50% and signalling patience.

Conversions here use 17.1527 pesos to the US dollar, the reference rate determined on 15 September 2026.

BBVA Research has put a number on the exposure. An extra percentage point costs about 37.9 billion pesos.

That is roughly US$2.2 billion, and it would lift debt service from 3.7% to 4.0% of national output.

So the gap between the budget’s assumption and the bank’s position is a real fiscal item, not a technicality.

The revenue side is already behind. Income-tax collection fell 6% in real terms through July.

That left it about 96 billion pesos short of the approved budget, or some US$5.6 billion.

A record tax take is being projected by a treasury that is currently missing its existing target.

One claim circulating is that the 2027 package raises taxes on soft drinks and video games. It does not.

Those levies were legislated in the 2026 package and took effect in January.

The finance ministry states that there will be no new taxes and no increases in general rates.

Tobacco does rise, but under a schedule already passed, from 0.8516 pesos per cigarette to 0.9197 next year.

The same misplacement applies to tariffs of up to 50% on Chinese cars and other goods.

Those covered about 1,400 tariff lines and took effect on 1 January 2026, not in the new budget.

The state oil company’s budget line falls to about 204.1 billion pesos, roughly US$11.9 billion.

That is down from 263.5 billion approved for 2026, about US$15.4 billion.

Federal transfers for debt service drop to around 81.1 billion pesos, near US$4.7 billion, a fall of about 70%.

The ministry projects a financial surplus at the company once transfers are counted.

Independent analysts are unconvinced, noting Pemex has received far more in support than it has contributed.

The cut assumes a turnaround that has not yet shown up in the company’s own numbers.

There was no exchange-rate fixing on 16 September, because Independence Day is a banking holiday.

The last rate before it, determined on 15 September, was 17.1527 pesos to the dollar.
