- Copper, Chile’s main export, fell on Thursday: the CPER copper fund lost 2.71%, and US-listed miner Southern Copper dropped 7.31%.
- Defensive names held firm, with Aguas Andinas up 1.2% and Vapores up 0.7% as traders sought shelter.

Today’s Focus
Chilean shares had a rough Thursday session. The S&P IPSA, the Santiago exchange’s benchmark, covering its largest companies, dropped 1.88% to 10,780 points.
The peso also lost ground. It took 986.2 Chilean pesos to buy one US dollar, a 0.46% weakening from the prior close.
The main culprit was copper. Chile’s most important export fell: the CPER copper fund lost 2.71% and Southern Copper dropped 7.31% in New York, weighing on mining and industrial names.
Lithium producer SQM-B fell 3.2%, while retailer Falabella slipped 1.5% and Copec dropped 2.9%.
What matters today. Copper’s slide set the tone for Chile’s equity and currency markets, outweighing mostly domestic corporate news.

01 The session in one read
Chile’s stock market closed firmly lower on Thursday as a slide in copper prices rippled through the benchmark S&P IPSA index. The index shed 1.88% to end at 10,780 points.
The peso also slipped. One US dollar now buys 986.2 Chilean pesos, a 0.46% move that reflects foreign investors trimming exposure to commodity-linked emerging markets.
The session’s anchor was copper, which fell on Thursday: the CPER copper fund lost 2.71%. That weighs directly on Chile’s largest mining names and the currency alike.
Still, there was no stampede. Defensive utilities like Aguas Andinas and Colbún held up, a sign that local investors were rotating rather than fleeing the board.
Assessment — A copper-led retreat, not a panic HIGH
The fall looks like a measured reaction to weaker commodity prices rather than a disorderly sell-off. Turnover was modest, and the peso moved far less than shares. The variable to watch is whether copper stabilises after Thursday’s fall or breaks lower, since that will decide whether the IPSA recovers Tuesday’s level near 10,900 or keeps falling.
02 The day’s numbers
| Measure | Level | Change | Read |
|---|---|---|---|
| S&P IPSA | 10,780 | −1.88% | Copper-led equity decline |
| USD/CLP | 986.2 | +0.46% | Peso weakens with commodities |
| Copper fund (CPER) | US$38.47 | — | Fell 2.71% on the day |
The IPSA closed at 10,780, down from 10,987 on Wednesday and 10,927 on Tuesday, so the index gave back more than a full session of gains.
The peso’s move to 986.2 per dollar (from 981.7) is small but directionally telling: a weaker peso usually goes with lower copper.

The session read
The S&P IPSA eased 1.88%, with breadth negative — 2 of 11 names higher. Utilities led, while Consumer Staples lagged.
03 Why it moved — copper sets the tone
Copper’s slide is the market’s centre of gravity. Chile is the world’s largest producer, so the red metal’s moves feed directly into earnings expectations for miners and industrial firms.
The fall comes as global investors grow more cautious. Technology shares in the United States sold off sharply, and that risk aversion spilled over into commodity-linked Latin American markets.
Retailers and fuel companies fell too: Falabella lost 1.5% and Copec 2.9%.
The RT economic calendar lists no Chilean data release for the session, so the move was driven by copper and global risk appetite.
04 The day’s movers
| Driver | Level / Move | Change | Note |
|---|---|---|---|
| SQM-B | $21m turnover | −3.2% | Lithium giant leads the decline |
| Copec | $6m turnover | −2.9% | Fuel and forestry heavyweight hit |
| Parque Arauco | $7m turnover | −2.7% | Mall operator slides with retail |
| Banco Santander Chile | $8m turnover | −2.5% | Banking proxy weakens |
| Aguas Andinas | — | +1.2% | Defensive utility gains |
| Vapores | — | +0.7% | Shipping firm among few gainers |
The most-traded names all fell, which is a clear signal of broad selling pressure. SQM-B, the lithium miner, was the weakest large-cap with a 3.2% drop on modest turnover of US$21 million.
Banco Santander Chile and Copec also featured heavily in the fall, losing 2.5% and 2.9% respectively. The only real gains came in defensive areas — Aguas Andinas rose 1.2% and Vapores added 0.7%.
05 The regional scoreboard
| Index | Country | Change |
|---|---|---|
| S&P IPSA | Chile | −1.88% |
| Ibovespa | Brazil | −1.15% |
| IPC | Mexico | −1.25% |
| COLCAP | Colombia | −1.25% |
Chile’s decline was the steepest of the five major markets, while Mexico, Brazil and Colombia all lost more than 1%.
The coordinated fall across Latin America points to a shared external driver: softer metals prices and rising caution in global equity markets, with the Nasdaq down about 2.6%.
06 The technical picture
The IPSA closed at 10,780 on Thursday. That is below Tuesday’s 10,927 and Wednesday’s 10,987, and the index has now lost its gains from the start of the week.
The peso, at 986.2 per dollar, has weakened by 1.2% since Tuesday’s 974.7. A further fall in copper would probably keep that pressure on.
What Prediction Markets Say
Polymarket, a prediction market, gave 97.9% to no change in the Central Bank of Chile’s policy rate at its October decision, with US$14,479 traded (read at 8:30 pm ET on 22 October).
These prices are bets, not polls. They can move quickly with each new data release.
Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.
07 What to watch
- Copper: Whether the copper fund recovers from its 2.71% fall will set the tone for mining shares and the peso.
- SQM-B: The lithium producer fell 3.2%; the LIT lithium fund lost 3.99%, so lithium prices remain the key driver for SQM.
- Peso: The dollar at 986.2 pesos is the highest in this week’s data; another rise would add to import costs.
- US tech spreads: Global risk appetite, especially from the Nasdaq’s slide, keeps pressure on emerging-market equities.
Background: Chile Stocks Rise 0.5% as Retailers Lead.
