Today’s Focus
Chile’s market did not trade on Friday. The Bolsa de Santiago was closed on 18 September for Fiestas Patrias.
The last IPSA close stands at 11,381.18 points from Thursday 17 September. That session ended at one in the afternoon.
The currency kept moving even with Santiago shut. The offshore dollar quote was 958.97 pesos, down 0.31% on the day.
That is not an official local print. With the exchange closed, the offshore quote is the only live reference available.
The weekly trend is the number that matters. The dollar is 1.75% higher against the peso since Friday 11 September, measured to Friday 18 September.
What matters today. Santiago reopens on Monday 21 September. Two days of global news will be priced into one session, and the peso’s weekly trend still points one way.

Friday, 18 September 2026 close. Gold, silver and the oil fund in US dollars.
01 The session in one read
There was no session to read on Friday. The Bolsa de Santiago was closed for Independencia Nacional, and it stays shut through the weekend.
The last available close is therefore Thursday’s 11,381.18 points. It was an early session that ended at one in the afternoon.
The dollar-denominated view of Chilean equities is the cleaner one this week. It strips out a peso that moved while the local market sat idle.
The dollar is 1.75% higher against the peso this week, measured to Friday 18 September. That line is the uncomfortable one.
02 The week’s numbers

03 Why it moved — a holiday, not a verdict
The closure is the whole story for Friday. Chile’s Fiestas Patrias begin on 18 September, a public holiday.
That is why Thursday’s session ended early. The exchange has a standing policy of a one o’clock close on the business day before the holidays.
The peso still moved offshore, and it moved with the dollar. The dollar index was 100.215 on Friday, up 1.10% on the week.
Chile pays 4.50% at the policy rate, well below Brazil and Colombia. That gap leaves the peso more exposed when the dollar firms.
Copper gave the peso a counterweight. The CPER tracker rose 1.44% on Friday and 2.68% over the week, and China’s physical demand recovered.
None of this is a Chilean verdict. It is a holiday, a firm dollar and a market that will not answer until Monday.

05 The regional scoreboard
| Market | Close | Session | Note |
|---|---|---|---|
| Ibovespa (Brazil) | 185,229.17 | -0.41% | Week to date -1.06% |
| S&P/BMV IPC (Mexico) | 63,375.93 | -0.78% | Official close; week to date -0.86% |
| S&P IPSA (Chile) | 11,381.18 | Closed | Last close 17 September, early session |
| MSCI COLCAP (Colombia) | 2,548.22 | +1.03% | Per La República, single source |
| Latin America fund (ILF) | US$35.04 | -1.16% | Week to date -2.59% |

| Chile fund (ECH) | US$39.45 | -0.38% | Week to date -0.08% |
Chile did not trade on Friday. The regional fund lost 1.16% on Friday and 2.59% over the week.
The currency picture was mostly one-sided. The dollar rose against the Brazilian, Mexican and Colombian currencies on the day, while the offshore Chilean peso quote firmed 0.31%.
The Peruvian sol also firmed. The dollar closed at 3.374 soles, down 0.09% on the session.
06 The technical picture
The IPSA’s technicals are frozen at Thursday’s close, when the index gained 1.30%. No new reading arrives until Monday’s reopening.
The peso’s technicals are the more revealing set. The offshore quote at 958.97 is above its 50-day average of 930.11 and its 200-day average of 904.41.
The 52-week high for the dollar is 966.03 pesos. Friday’s offshore quote sits within seven pesos of that level.
The 14-day relative strength index for the dollar-peso pair is 68.8. That is below the 70 line but close to it.
The Chile fund tells the same story. ECH trades below both its 50-day and 200-day averages, with an RSI of 33.4.
Monday’s reopening will show whether local equities follow the offshore fund or the peso. Until then, both readings stand.
07 What to watch
- Monday’s reopening: Two days of global news will be priced into the IPSA in a single session.
- The weekly dollar trend: A further weekly rise would matter more than any single day’s move.
- The 966.03-peso high: The offshore quote at 958.97 is within seven pesos of the 52-week peak.
- Copper and lithium: CPER rose 2.68% on the week while LIT fell 1.38%, and SQM’s two listings diverged.
- The central bank minutes on 24 September: The record of the latest policy meeting may show how the board weighed cost pressure.
- Chile’s producer price index on 24 September: Forecast 21% year on year against 20.5% prior.
