The Mexico sovereign rating outlook investment impact of HR Ratings’ 15 October cut now depends on Congress and the 2027 budget. Deputies have already backed the Revenue Law, and the Senate vote and the spending budget will show whether the plan supports the fiscal path HR doubts.
HR Ratings lowered Mexico’s long-term rating from BBB+ to BBB with a stable outlook, as set out in HR Ratings Mexico Downgrade Reasons Explained. The rating is still investment grade, so the question now is which dates and data could move it again.
Mexico Sovereign Rating Outlook Investment Impact and the Budget Calendar
Deputies approved the 2027 Revenue Law in the general vote on Wednesday 14 October 2026, by 331 votes to 118, according to La Crónica de Hoy. Morena, the governing party, and its allies voted yes, while the opposition PAN, PRI and Citizens’ Movement voted no.
Hacienda’s calendar, as carried by UnoTV, gave the Chamber until 20 October, the Senate until 31 October and the spending budget until 15 November. Deputies still had to vote on individual articles after the general vote, and the Senate stage is next.
The package assumes a broad public-sector deficit of 3.9% of GDP in 2027, which Hacienda says is 1.8 points below 2024. It also projects tax revenue of 15.9% of GDP without new taxes.
Legislative leaders said the excise-tax proposals would be reviewed during the legislative process, according to IDC. The final numbers may therefore differ from the September draft that HR is testing.

Where HR and Hacienda Disagree
For 2027, HR projects a broad deficit of 4.7% of GDP, while Hacienda’s package targets 3.9%. That gap of 0.8 points is the clearest measure of how far the two views are apart.
HR sees net debt rising from 52.6% of GDP in 2025 to 54.5% in 2026 and 56.4% in 2027. It then reaches 61.2% in 2030, with interest costs averaging 3.9% of GDP, according to López-Dóriga.
On growth, Hacienda expects 1.5% to 2.5% in 2027, after a range of 1% to 2% for 2026. HR says sustained growth above 2.5% would support an upgrade, so the top of Hacienda’s range is HR’s threshold.
HR also expects Pemex, the state oil company, to need public transfers at least through 2029, as explained in the Pemex explainer. Hacienda’s package assumes a financial surplus for Pemex, which is the other number to check.
What the Other Agencies Can Still Do
S&P kept Mexico at BBB on 12 May 2026 but changed its outlook to negative, according to Expansión. It said it could cut the rating within 24 months if deficits do not fall in time, and could restore a stable outlook if fiscal consolidation becomes significant.
Moody’s cut Mexico to Baa3, the lowest investment-grade step, on 20 May 2026 with a stable outlook, as covered in Moody’s Cuts Mexico to Baa3, Last Rung of Investment Grade. Hacienda says Mexico keeps investment grade with all eight agencies that rate its sovereign debt.
HR’s cut does not change those ratings, and each agency decides on its own timetable. Hacienda points to reserves above US$256 billion and an IMF flexible credit line of US$24 billion as buffers, according to El Financiero.
What Banxico and the Peso Add
Banxico, the central bank, held its policy rate at 6.50% on 24 September, its third hold in a row, by unanimous vote. It dropped its earlier guidance to stay put and now ties future moves to inflation, the peso and the economy, according to Diario de Yucatán.
Headline inflation was 3.42% in the first half of September, and INEGI put the full month at 3.45% on 8 October. The US Federal Reserve lifted its range by 25 basis points to 3.75% to 4% that month, so Mexico’s interest-rate advantage is narrowing.
A weaker peso can lift import prices, and Banxico says it is watching how exchange-rate moves pass into consumer prices. That pass-through is the bridge between fiscal worries and household costs.
What It Means for You
For US investors in Mexican government bonds, Pemex debt or the peso, the HR cut is a signal and the budget votes are the next data points. Funds set their own rules on which ratings count, so the fund’s prospectus is the place to check.
For expats and travellers, the channel to watch is the peso and prices, because nothing in the announcement alters visas or taxes. The Mexico City expat guide covers everyday costs.

What Is Not Known
The market reaction on Friday 16 October is not known, because Mexican outlets covered the news only on Thursday evening. HR’s full press release could not be opened, so its numbers come from outlets that quote it.
Congress may change the 2027 package before the final votes, and the final deficit target could differ from 3.9%. Whether HR revisits its 4.7% projection after the final budget is not stated.
S&P has not said when it will resolve its negative outlook, and the date of Banxico’s next decision was not confirmed. HR’s own rating decisions on Pemex could not be confirmed either.
