- Grupo México led the blue chips with a gain of 3.65%, while América Móvil slipped 0.21%.
- Turnover reached 18.49 billion pesos (about US$1.07 billion) across 185.8 million shares, the news agency EFE reported.

Today’s Focus
Mexico’s S&P/BMV IPC, the country’s main stock index, rose 1.45% on Tuesday to close at 64,456.59. Forbes México called it the index’s best session since 21 August 2026. The peso went the other way, easing to a Banxico reference rate of 17.3015 per dollar.
The gains were broad. Grupo México, the mining and rail group, jumped 3.65%, Cemex rose 2.78% and Banorte, the largest home-grown bank, climbed 1.78%. América Móvil, the telecoms heavyweight, dipped 0.21%.
The session lacked a single Mexico-specific catalyst. The S&P 500 finished flat and the Nasdaq rose 0.45%, while Brent crude slid towards US$98 a barrel.
What matters today. Mexican shares rallied while the peso slipped. That is a split between equity risk appetite and a narrowing interest-rate advantage over the United States.
01 The session in one read
Mexico’s benchmark S&P/BMV IPC index closed at 64,456.59 on Tuesday, up 919.63 points or 1.45%. The index still sits 10.6% below its 52-week high of 72,111.41.
The peso eased against the dollar. Banco de México, the central bank known as Banxico, set its FIX reference rate at 17.3015 per dollar, 0.47% above Monday’s 17.2203. In the interbank market the currency closed near 17.29, a fall of 0.37%, Forbes México reported.
Airport and materials names led the board. Grupo Aeroportuario del Centro Norte rose 3.99% and Grupo México 3.65%, with Cemex up 2.78%. Walmex, the retail bellwether, gained 1.33% and Banorte 1.78%.
The evidence points to two markets moving apart. Shares took their cue from Wall Street technology strength and cheaper crude. The peso tracked the gap between Banxico and US policy rates instead. Banxico left its benchmark rate at 6.50% on 6 August 2026, its own announcement shows. A further cut would trim the peso’s yield appeal. The IPC’s 1.45% rise was its best in a month, but one session is not a trend.

03 Why it moved — a rate gap and a friendlier tape
The peso’s weakness reflects a simple sum for foreign investors. The narrower the gap between Mexican and US interest rates, the smaller the reward for holding peso assets.
Banxico held its policy rate at 6.50% on 6 August 2026, its own announcement shows. Any further easing would narrow the spread over US rates again.
Equities had a friendlier backdrop. The S&P 500 finished flat, the Nasdaq rose 0.45% and the Dow Jones Industrial Average fell 0.36%.
Crude was softer, with Brent easing towards US$98 a barrel. EFE put the airport operator Grupo Aeroportuario del Centro Norte among the day’s best blue chips.
04 The day’s movers
| Stock | Change | Note |
|---|---|---|
| Grupo Aeroportuario del Centro Norte (OMA B) | +3.99% | Airport operator led the blue chips |

| Cemex (CEMEXCPO) | +2.78% | Materials strength |

| Banorte (GFNORTEO) | +1.78% | Largest home-grown bank |

| América Móvil (AMXB) | -0.21% | Telecoms heavyweight slipped |
| Televisa (TLEVISACPO) | -1.95% | Weakest of the heavyweights |
Breadth backed the move. EFE counted 507 risers against 247 fallers and 35 unchanged among the 789 companies traded, on turnover of 18.49 billion pesos (about US$1.07 billion).
Losers among the heavyweights were few. Televisa fell 1.95%, Vesta, the industrial property developer, lost 1.57% and Alsea, the restaurant operator, 0.99%.

06 The technical picture
The IPC’s close at 64,456.59 leaves it about 10.6% below the 52-week high of 72,111.41. Tuesday’s intraday range ran from 63,505.34 to 64,477.59.
For the peso, the 17.3015 FIX is 7.9% below the dollar’s 52-week peak of 18.7765. The next round level on the way up is 17.50.
07 What to watch
Mexico City trading reopens on Wednesday, September 23, 2026. These are the points that matter.
- Banxico’s next rate decision: The central bank’s next move will shape the peso’s yield appeal and the differential driving currency flows.
- US jobless claims: Weekly labour market data shifts expectations for Federal Reserve policy, the other half of the differential.
- Mexican inflation: A firmer price reading would limit Banxico’s room to cut rates, supporting the peso against the dollar.
- Crude prices: Softer oil is a mixed signal for Mexico’s fiscal outlook and could weigh on energy-linked shares.
Background: Mexico’s IPC Falls 0.78% as the Peso Slips Before Banxico.
