Brazil’s manufacturing PMI fell to 44.8 in September from 46.3, its fastest contraction since April 2023, according to a regional market briefing dated Friday, October 2, 2026. Any reading below 50 signals contraction. Brazil has now fallen well below that line.
Mexico moved the other way, but only barely. Its S&P Global PMI rose to 50.3 from 49.8, while Colombia’s Davivienda manufacturing PMI edged up to 54.6 from 54.3. The region isn’t moving as one.
Uneven Output, Uneven Pressure
Chile’s Imacec economic activity index fell 1.0% year on year in August, after a 1.5% decline in July. Copper mining dropped 17.4%. In Peru, the statistics agency INEI reported Lima annual inflation of 4.55% in September, up from 4.44% in August and above the central bank’s 1% to 3% target range.
Argentina’s tax agency, ARCA, reported September revenue of AR$21.36 trillion, about US$14 billion at AR$1,525 per dollar. That’s a 38.3% nominal increase, following roughly AR$20.5 trillion in August.
In Mexico, INEGI’s business confidence index rose to 48.4 in September from 48.3. It marked the 19th consecutive month below 50. The finance ministry, SHCP, reported a January-to-August fiscal deficit of MXN 739 billion, about US$40 billion at 18.30 pesos per dollar. The programmed figure was MXN 1.015 trillion.
What Mexico’s Business Group Sees
The Mexican Institute of Finance Executives, IMEF, called its September results “mixed signals.” Its manufacturing indicator reached 50.0, up from 49.9 in August. The group said activity had stopped deteriorating as quickly, but the evidence wasn’t enough to confirm a broad recovery. Its non-manufacturing indicator, covering services and commerce, rose 0.2 points to 49.2 and stayed below 50. The size-adjusted version of that index dropped 1.2 points to 48.5.
IMEF linked the slight improvement to two things. One was public investment in physical works, which rose between April and June, “very probably” because of the football World Cup. The other was exports of computer equipment, which grew 200% through July. IMEF added that most inputs for those goods came from Asia and that local value added was low.
The warnings were just as specific. Public construction spending fell 13% from June to July. IMEF said rigid spending and rising pension costs raised the chance of a sovereign credit-rating cut. It named the review of the USMCA, the North American trade agreement, as the main exposure. It also said the Bank of Mexico was expected to hold its interest rate for the rest of the year, while inflation kept upside risk, mainly from services.
Markets Split, Dollar Looms
Brazil’s Ibovespa rose 0.46%, a gain the briefing described as a local rebound rather than a regional signal. Mexico’s IPC fell 0.97% in the briefing’s regional setup, Chile’s IPSA slipped 0.56%, and Argentina’s Merval dropped 2.15%. Turnover leaders in Brazil were banks, oil and iron ore. The briefing characterized the large percentage gains in Casas Bahia and Azzas as small-turnover moves.
The briefing said a firmer dollar was a headwind for regional currencies and local-currency bonds. A firm dollar also raises the local-currency cost of foreign debt and weighs on imported inflation. In the United States, the ISM manufacturing index came in at 54.5 against a forecast of 55, while its prices-paid gauge rose to 77.9 from 71.1. A US payrolls report was due at 09:30 Brasília time. A softer jobs reading could ease the dollar’s pressure; a stronger one could increase it.
Why This Matters: The numbers show a region where gains and losses aren’t landing in the same places. Brazil’s factory contraction, Chile’s copper-driven slowdown and Peru’s above-target inflation are readings that tend to reach households through jobs and prices. Mexico’s picture shows how thin the recovery is: 19 months of weak business confidence, a World Cup-linked bump in public works, and a 13% drop in public construction spending. IMEF’s warning about pension costs and rigid spending raises a question about how governments will protect public services if borrowing gets pricier. A firm dollar adds to that squeeze by raising foreign-debt costs and imported inflation. That’s one reading of the facts, and it gives public policy a larger role than the day’s market moves suggest.
