Chilean Peso Hits an 11-Month Low of 962 per US Dollar on September 23 as Chile’s IPSA Stock Index Edges Up 0.20%
Key Facts
- —The country. Chile, 19.9 million people, has been governed by President José Antonio Kast since 11 March 2026, when he succeeded Gabriel Boric.
- —The money. The currency is the Chilean peso. On 23 September one US dollar bought 962.375 pesos, up from 947 the day before.
- —The index explained. The S&P IPSA is Chile’s benchmark stock index. It tracks the largest and most actively traded companies on the Santiago exchange, from banks to lithium producers.
- —The news. On Wednesday 23 September 2026 the IPSA rose 0.20% to 11,450 points, while the peso fell 1.62% to its weakest close since October 2025.
- —What is new. Copper, Chile’s biggest export, slipped 0.42% to US$6.68 a pound in London, two weeks after a record. Rising US bond yields did the rest.
- —What it means for you. A weaker peso raises the peso price of imported fuel, cars and electronics. Salaries paid in dollars go further; peso savings buy less abroad.
- —The caveat. The index is still 1.5% below its 12-month high of 11,628 points. One currency session is not proof of a lasting trend.
Today’s Focus
Chile’s benchmark S&P IPSA index inched up 0.20% to 11,450 points on Wednesday, but the calm headline masked a sharp slide in the peso. The currency weakened 1.62% to 962.375 per dollar, its weakest close in almost a year, as global markets reassessed US interest-rate expectations.
The session’s quiet resilience in stocks came largely from the currency itself. A weaker peso flatters the earnings of Chile’s major exporters and domestically focused businesses alike, even as it signals caution about the country’s near-term economic outlook.
Copper, the country’s dominant export, offered little support. Prices for the red metal eased 0.42% to US$6.68 a pound, leaving investors to focus on domestic corporate news and global rate dynamics.
What matters today. The peso’s slide to a near one-year low is the session’s defining feature, cushioning the stock index while signalling a broader rethink of US interest rates.
01 The session in one read
Chile’s stock market finished a touch higher on Wednesday, but the real action was in the currency. The S&P IPSA — the main index tracking Chile’s largest listed companies — added 0.20% to close at 11,450 points.
The peso, meanwhile, slid to its weakest level in almost a year. It took 962.375 pesos to buy one US dollar, a move of 1.62%, as investors reassessed how aggressively the Federal Reserve might keep raising rates.
Local media described the dollar’s rise to its highest level in almost a year, driven in part by a softer copper market. Copper, which provides a big chunk of Chile’s export income, slipped 0.42% to US$6.68 a pound on the London Metal Exchange.
The evidence points to a market drifting higher on a weak peso rather than on fresh enthusiasm for Chilean businesses. Most of the 11 most-traded local stocks fell, yet the headline index still rose, which suggests gains were concentrated in a few exporters or defensive names.
The variable to watch is the US interest-rate narrative. If markets continue betting on further Federal Reserve rate rises, the peso could remain under pressure, which would likely keep this pattern of soft stock-market resilience in place.
02 The day’s numbers
| Measure | Level | Change | Read |
|---|---|---|---|
| S&P IPSA | 11,450 | +0.20% | Index drifted higher despite a sour mood in global equities |
| USD/CLP | 962.375 | +1.62% | Peso hit its weakest close in roughly a year |
| Copper (LME) | US$6.68/lb | −0.42% | Soft commodity prices failed to support the currency |
| US 10Y yield | 5.116% | +2.94% | Rising global yields underpinned the dollar’s strength |
| 52-week position | 11,628 high | −1.5% | IPSA sits a stone’s throw from its best level in a year |
The IPSA’s modest gain came against a backdrop of sharp moves elsewhere. The US S&P 500 fell 0.75% and the Nasdaq dropped 0.69%, as a further rise in the US 10-year Treasury yield to 5.116% gave investors fresh reasons to favour the dollar.
For Chile, that dollar demand translated into direct pressure on the peso. The local currency’s weakness was the most important market signal of the day, even as the country’s stock gauges stayed relatively calm. Rio Times · Live Market Intelligence

03 Why it moved — a weak peso cushions exports, but copper slips
The session offered a textbook case of a currency-driven stock market. When the peso falls, any Chilean company that sells goods abroad — or earns dollar-linked revenue — sees its earnings become more valuable when converted back into local currency.
That helped offset a disappointing session for copper. The metal, which is Chile’s largest export and a key driver of the country’s tax revenues and wages, slipped as global risk appetite faded and the dollar strengthened.
Local economists cited in Chilean media are watching whether the peso’s slide is a short-term correction or the start of a longer move. With the dollar touching its strongest level in nearly a year against the peso, the question is whether this reflects durable US policy expectations or just a brief burst of dollar buying.
04 The day’s movers
| Driver | Level / Move | Change | Note |
|---|---|---|---|
| ILC | — | +2.1% | Construction-sector holding led the session’s gains |
| Falabella | — | +0.9% | Top-traded retailer rose amid cautious local buying |
| SQM-B | — | +0.4% | Lithium giant found buyers despite soft commodity tone |
| Quinenco | — | −1.0% | Conglomerate was the session’s biggest laggard |
| Cencosud | — | −0.8% | Supermarket group slipped despite defensive reputation |
Trading activity was led by Banco de Chile, which trades under the ticker CHILE and is one of the country’s largest lenders, with US$26 million in turnover and a gain of 0.8%. SQM-B, the lithium producer that often acts as a proxy for global commodity sentiment, added 0.4% on US$20 million traded.
Falabella advanced 0.9% on US$16 million in turnover, making it one of the more actively traded and better-performing names of the day. Inversiones La Construcción led all gainers with a 2.1% rise, while Quinenco, the conglomerate controlled by the Luksic family, dropped 1.0%.
05 The regional scoreboard
| Index | Country | Change |
|---|---|---|
| S&P IPSA | Chile | +0.20% |
| Ibovespa | Brazil | −0.86% |
| IPC | Mexico | −0.22% |
| COLCAP | Colombia | +0.92% |
| BVL Perú | Peru | −1.56% |
Chile’s IPSA was a rare bright spot in a mostly lower regional session. The live market board above carries the verified closes for major Latin American indices and currencies.
Brazil’s Ibovespa fell 0.86%, while Peru’s BVL slumped 1.56% as regional investors weighed the same global themes: a stronger US dollar and persistently high US bond yields.
06 The technical picture
For chart-watchers, the IPSA’s close of 11,450 points leaves it just 1.5% below its 52-week high of 11,628. That positioning suggests the longer-term trend in Chilean equities remains intact, even as individual sessions turn choppy.
On the currency side, the peso is sitting almost exactly at its 52-week low — 962.375 per dollar. A sustained move above this level could open the door to further losses, while a rapid recovery would suggest the dollar’s surge has run its course.
07 What to watch
- US interest-rate expectations: Traders will watch Federal Reserve signals closely. More hawkish rhetoric could keep the dollar strong and the peso under pressure.
- Copper prices: Copper is Chile’s economic anchor. Sustained weakness in the metal would squeeze export revenues and drag on equities and the local currency.
- Peso’s 52-week low: A decisive break above 962 per dollar could trigger another round of selling, with 1,000 pesos emerging as a psychological marker.
- Lithium and SQM: SQM-B remains a barometer for global commodity sentiment. Volume and direction in the lithium giant often shape the broader local market tone.

Frequently Asked Questions
What is the S&P IPSA?
It’s Chile’s main stock index, which tracks the performance of the country’s largest and most actively traded companies listed on the Santiago Stock Exchange.
Why did the Chilean peso weaken?
The peso fell because a strengthening US dollar and rising American bond yields made investors favour US assets over emerging-market currencies like the Chilean peso.
How does the peso affect Chilean stocks?
A weaker peso helps exporters and companies with dollar-linked revenue because their earnings become more valuable when converted back into local currency. This often cushions the local stock market.
Why is copper so important for Chile?
Copper is Chile’s biggest export. Its price heavily influences government revenue, business confidence and the value of the peso, making it a key signal for investors.
