Chile Markets: IPSA & the Peso — September 25, 2026
Key Facts
- Chile’s IPSA fell 1.30% to 11,301, its heaviest one-day drop in the recent run, as the market’s biggest lithium, banking and retail names all headed lower.
- The peso weakened to 963.25 per dollar up 0.09%, close to but not at the weak end of a 52-week range of 851.38 to 969.01 per dollar.
- SQM-B, the lithium bellwether closed down 0.84% at CLP65,305, with the sector’s sliding sentiment setting the tone for the wider index.
- Santander Chile led the bank retreat falling 2.28% to CLP78.37, one of the heaviest single-stock losses on the day.
- Copper offered no safety net with the IPSA down 1.30% even as the metal held recent levels, showing domestic pressures outweighed the usual commodity support.
Today’s Focus
Chile’s benchmark S&P IPSA — the 30-share gauge of the Santiago stock exchange — closed at 11,301, down 1.30% on the session.
The fall was spread across the market’s biggest sectors: SQM and lithium, banks like Santander Chile, and retailers Falabella and Cencosud all lost ground, leaving few places to hide.
The peso added to the pressure, slipping to 963.25 to the dollar, a 0.09% decline that left it near the weak end of a 52-week range of 851.38 to 969.01.67–963.25.
The session inverted the usual logic: copper, Chile’s main export and a reliable anchor for the peso and the IPSA, did not rescue the market.
What matters today. A broad-based decline across lithium, banking and retail dragged the IPSA lower while the peso closed at its weakest level in nearly a year.
01 The session in one read
Chilean equities fell hard on Thursday, with the S&P IPSA — the main share index that tracks the 30 largest and most liquid companies on the Santiago bourse — closing at 11,301, a decline of 1.30%.
That was the worst one-day move in recent sessions and pushed the index further away from its 52-week high of 11,628, leaving it 2.8% below that peak.
The currency did not help. The dollar bought 963.25 Chilean pesos by the close, down 0.09%, meaning the peso was fractionally weaker and sitting exactly at the top of its 52-week range of 851.67 to 963.25.
In plain terms, the peso closed at its weakest level in almost a year — since October 2025 — and that normally spooks foreign investors holding Chilean assets.

02 The day’s numbers
| Measure | Level | Change | Read |
|---|---|---|---|
| S&P IPSA | 11,301 | −1.30% | 2.8% below the 52-week high of 11,628 |
| USD/CLP | 963.25 | +0.09% | At the 52-week high; peso weakest since Oct 2025 |
| Copper (anchor) | — | +0.61% | No relief for the index or peso |
| 52-week range | 8,676–11,628 | — | IPSA sits in the upper band but fading |
The table shows the awkward contrast of the day: equities fell hard while the peso barely moved but stayed near the weak end of its one-year range.
The IPSA’s 2.8% distance from its one-year high suggests the index has not fully lost its 2026 gains, yet Thursday’s drop signals momentum is stalling. Rio Times · Live Market Intelligence

03 Why it moved — lithium, retail and bank selling
The most traded names tell the story. CHILE, the cross-listed Chilean equity tracker, fell 1.5% on US$16m of turnover, showing broad index selling rather than one stock’s problem.
CMPC, the pulp and paper group, was a rare bright spot, up 2.4% on US$6m, while Quinenco gained 2.5% on lighter volume.
But the heavyweight direction was down: Falabella lost 1.7% on US$5m, BSantander fell 1.8% on US$5m, and Enelam slipped 1.8% on US$4m.
For readers new to Chile, these are the country’s big banks, retailers and utilities — the companies that dominate pension funds and retail investor portfolios.
04 The day’s movers
| Driver | Level / Move | Change | Note |
|---|---|---|---|
| CHILE (tracker) | — | −1.5% | Most traded; US$16m turnover |
| QUINENCO | — | +2.5% | Top gainer on low volume |
| CMPC | — | +2.4% | Pulp and paper; US$6m |
| MALLPLAZA | — | −2.0% | Worst domestic faller |
| BSANTANDER | — | −1.8% | Bank selling; US$5m |
| FALABELLA | — | −1.7% | Retailer; US$5m |
The movers list is a roll call of Chile’s consumer and financial economy, and the message was cautious.
Quinenco and CMPC aside, almost every actively traded domestic share fell between 1.4% and 2.0%, led by Mallplaza and the two Enel utilities.
05 The regional scoreboard
| Index | Country | Change |
|---|---|---|
| Ibovespa | Brazil | −0.99% |
| IPC | Mexico | −0.43% |
| S&P Merval | Argentina | −1.00% |
| COLCAP | Colombia | −0.12% |
| BVL Perú | Peru | +0.43% |
Chile was not alone in falling, but it was the region’s worst major market on the day.
Brazil’s Ibovespa — Brazil’s main stock index — lost nearly 1%, while Peru’s modest 0.43% gain made it the only bright spot in a region that closed in the red.
06 The technical picture
The IPSA’s 52-week range is 8,676 to 11,628, and Thursday’s close at 11,301 leaves the index 2.8% under its high but still well above the bottom.
There is no reliable verified support line in the current data, but the index is now closer to the psychological 11,000 round number than to its peak.
For the peso, the technical picture is clearer and worse: USD/CLP closed exactly at 963.25, the top of its 52-week range, meaning a break above that level would open fresh multi-year lows for the Chilean currency.
07 What to watch
- Peso break: Whether USD/CLP pushes through 963.25; a decisive break would signal deeper pressure on Chilean assets
- Lithium mood: SQM-B and lithium peers for any sign of stabilising demand, a key driver of IPSA sentiment
- Copper follow-through: Whether copper can hold its recent level and finally lend support to the peso and equities
- Bank and retail flows: BSantander, Falabella and Cencosud for continued selling, which would confirm a defensive rotation
