The Mexico 2027 budget went to Congress on the constitutional deadline. Two of the three big rating agencies have already moved this year.
Mexico delivered its 2027 budget package to Congress on Tuesday. It went to the Chamber of Deputies at San Lazaro.
Finance Secretary Edgar Amador Zamora handed it over. The scheduled time was six in the evening, local.
The date is not a choice. Article 74 of the constitution requires delivery by 8 September.
The exception is a presidential transition year, when the deadline moves to 15 November. This is not one.
What the Mexico 2027 Budget Contains
The package has four parts. They are the revenue law, the spending proposal, the tax miscellany and the general economic policy criteria.
The criteria document carries the macroeconomic assumptions. Growth, inflation, the oil price and the exchange rate all sit there.
Those assumptions were not public at the time of writing. A six o’clock delivery leaves little of the working day.
We are therefore not reporting figures for total spending or the oil assumptions. Numbers circulating before delivery were estimates rather than the package.
What Is Known About the Targets
Official guidance before delivery pointed to a borrowing requirement of 3.5 percent of GDP for 2027. The estimate for this year is 4.1 percent.
The same guidance indicated a primary surplus near 1.1 percent of GDP. Historic public sector debt was put around 55 percent of GDP.
Private forecasters have been more pessimistic. Banamex has estimated deficits of 4.3 percent this year and 4.6 percent next.
The gap between those views is the story. It is roughly a full point of GDP.
Why the Rating Question Follows the Budget
Two of the three major agencies moved on Mexico this year. Both moves came in May.
Moody’s downgraded Mexico to Baa3 on 20 May, one notch above speculative grade. Its outlook is stable.
S&P revised its outlook to negative on 12 May while affirming the rating at BBB. A negative outlook signals a possible cut within about two years.
Fitch has Mexico at BBB minus with a stable outlook, affirmed in April. It has publicly said support for Pemex costs the sovereign a full notch.
The Revenue Problem
The difficulty is not spending discipline alone. Tax revenue has been flat in the first seven months of the year.
Income tax collection has fallen about 6 percent year on year over that period. That is the largest single revenue line.
Social programmes are also expanding. The president has said welfare spending will exceed one trillion pesos, or about US$59 billion, up from 987.16 billion pesos, around US$58.2 billion.
Meeting a lower deficit with flat revenue and higher transfers requires cuts elsewhere. Where they fall is what the spending proposal will show.
The Market Reaction
The peso weakened for a second consecutive session ahead of the delivery. It traded around 16.95 per dollar in the morning.
The move was small, roughly two tenths of a percent. Analysts described it as tracking emerging-market peers rather than reacting to Mexico specifically.
No rating agency issued a statement on 7 or 8 September. Agency responses to budgets usually take days or weeks.
What to Watch
The first marker is the criteria document itself. The oil price and production assumptions have historically been where optimism hides.
The second is Pemex. Agency commentary has repeatedly tied Mexico’s rating to the support the state oil company requires.
The third is the congressional calendar. The revenue law must clear the deputies by 20 October and the Senate by 31 October, with the spending bill due by 15 November.
