Chile stock market report: the IPSA rose 0.55% to 10,897.17 on Thursday May 28, a second straight gain that closed near the session high and put Santiago alongside Buenos Aires as one of only two majors to decouple from a regional risk-off. Copper near records did the structural work; the BCCh kept 4.50% with a June cut to 4.25% in play; the MACD has crossed up and the RSI is back above 55. The next reference is 11,045 overhead.
The Big Three
The IPSA closed at 10,897.17, up 0.55% in a tight 10,804 to 10,901 range that finished near the high. The second consecutive up session pushes the index above the 10,816 to 10,840 cluster that had been the lid and now becomes support, with 11,045 the first overhead reference.
The decoupling is striking. Brazil fell a third day, Colombia drifted before Sunday’s vote, Mexico reversed below 70,000; only Argentina and Chile closed higher. Copper, near records after Cochilco lifted its 2026 forecast, fed through the peso and mining heavyweights into the index.
The technical picture confirms. The MACD has crossed above signal with a +37.6 histogram and lines rising toward zero; the RSI has thrust to 55.28 from slow 44.46, the kind of widening that follows a successful base.

03 Why It Rose
Local Driver: copper still does the work
Copper is the single variable that explains the decoupling. The metal is trading near record highs after Cochilco lifted its 2026 forecast, and the pass-through is immediate: a firmer copper price feeds the peso, lifts the fiscal accounts, and bids the mining heavyweights. With the metal holding, Thursday’s gain looked like the natural continuation of the recovery that started after the early-May washout. President Kast’s 27% to 23% corporate tax cut remains the re-rating thesis behind targets like Morgan Stanley’s 13,700.
External Trigger: the rate cut that is still in play
The Banco Central de Chile’s 4.50% rate, with a June 25bp cut still in play, is the dovish optionality that supports the index when the global tape is hostile. Soft Q1 activity keeps the cut on the table while inflation has converged toward the 3% target faster than expected. The equity market reads it as cheaper financing and monetary tailwind on a copper-led economy.
§04 · Market Commentary
The way Chile recovered tells the story. The IPSA spent April and most of May rolling over, with the 10,816 to 10,840 cluster a ceiling that capped every bounce. Thursday was the second close back above it, finishing near the high, the cleanest signal the band has flipped from resistance to support. The January ATH at 11,721 is within 7.6% upside and the Morgan Stanley 13,700 target offers about 25.7%.
The momentum picture has flipped. The MACD has crossed above signal with a +37.6 histogram and lines rising from a deeply negative reading, the shape that follows a successful base. The risk is external: if the Iran tape worsens, copper would pull back as the global dollar firms, and the IPSA’s decoupling leans heavily on the metal. So long as it holds, the path of least resistance is up toward 11,045.
05 Technical Snapshot
The IPSA at 10,897 has cleared the 10,816 to 10,840 cluster and held above it on the close, flipping the band from resistance to support. Above are 11,045 (April peak) and 11,721 (January ATH); below, the 10,683 cloud edge and the 200-day near 10,152 are the structural floors. Momentum confirms: MACD bullish cross, RSI above slow and the midline. The setup favours continuation.
06 Forward Look
07 Questions & Answers
Verdict
Chile and Argentina were the only two majors to close higher Thursday: an idiosyncratic story strong enough to override the regional risk-off. For Chile that anchor is copper, near records after Cochilco lifted its forecast, with the BCCh at 4.50% and a June cut to 4.25% in play. The IPSA at 10,897 has cleared the band that capped April and May and finished near the high, the cleanest constructive close in weeks. The MACD has crossed up and the RSI is back above the midline. The next test is 11,045, then the January high at 11,721; the bigger picture is the 13,700 consensus target that hinges on whether the Kast tax cut clears Congress.
