Merval: Argentina’s Main Stock Index Falls 0.94% on 23 September 2026 as Country Risk Climbs to 566 Points

01 The session in one read

Argentine shares finished in the red on Wednesday, with the benchmark S&P Merval index dropping 0.94% to 2,969,545 points. That left the market a little more than 1% below its record high, a signal that investors are pausing after a powerful run rather than running for the exits.

The peso weakened slightly, closing at 1,516 per US dollar, a move of just 0.12%. It was a quiet, cautious session across the board, with turnover thin and much of the action concentrated in a handful of familiar bank and energy names.

The day’s tone matched the broader mood around President Javier Milei’s economic programme. The reform trade that has powered Argentine assets higher this year remains intact, but specific worries — especially rising country risk — are now tempering enthusiasm.

In New York, where Argentine officials have been meeting investors all week, the message was still one of long-term optimism. But local traders preferred to bank a little profit on banks and insurers, and to keep some powder dry.

02 The day’s numbers

The Merval’s 0.94% fall was enough to knock the index back below 2.97 million points, though it remains up sharply over the past year. Trading was not panicked — more a case of banks and financial shares giving back a sliver of their earlier gains.

The peso’s 0.12% decline to 1,516 per dollar holds particular significance because that is the very top of its one-year range against the greenback. A sustained move above that level would be a new multi-year low, so traders are watching the number closely.

03 Why it moved — banks retreat, YPF keeps energy hopes alive

The clearest driver of Wednesday’s decline was banking shares. A day after trading near record highs, investors took profits in the sector: Banco Supervielle fell 3.0%, Grupo Galicia dropped 2.9% and Banco Macro lost 2.7%.

That fits a pattern of consolidation in the Milei reform trade. Banks have been among the biggest beneficiaries of the government’s stabilisation plan, because falling inflation and a recovering economy support lending — but after such a strong run, even a mild wobble in sentiment encourages selling.

Energy group YPF was a notable exception, rising 1.6% with turnover of $14 million. The company is at the centre of a proposed $51 billion project to liquefy natural gas from the Vaca Muerta shale formation and export it by ship, a venture that has kept international attention and local optimism alive.

Local media highlighted two other developments: the government’s 2027 budget advanced in Congress, and JP Morgan’s regional chief executive said Argentina could regain investment-grade status within a few years. Both are positive for the long-term reform story, though neither was enough to stop Wednesday’s pullback.

04 The day’s movers

The session’s most-traded stock was YPF, with $14 million in turnover and a 1.6% gain. That is a telling detail: even on a down day for the index, the first place local and international traders went was the energy champion.

By contrast, Grupo Galicia saw $11 million change hands but fell 2.9%. The bank-heavy sell-off points to profit-taking in the sector most exposed to short-term rate and inflation expectations, rather than a broad loss of confidence in the reform story.

05 The regional scoreboard

Latin American markets were mixed on Wednesday. Colombia’s COLCAP rose 0.92%, the strongest move among the region’s main indices, while Peru’s BVL fell 1.56%, the steepest decline.

Argentina’s 0.94% drop and Brazil’s 0.86% fall were the largest index declines after Peru, suggesting a cautious tone across the biggest regional markets and currencies. The live whole-market board above carries the definitive closing levels.

06 The technical picture

The Merval remains within 1.2% of its all-time high, so Wednesday’s pullback reads more like a pause than a break in the uptrend. A decisive close above 3 million points would open a fresh leg higher, while sustained weakness below 2.95 million could trigger a deeper consolidation.

For the peso, the 1,516 per dollar mark is the key level. It sits exactly at the top of the 52-week range, so a daily close above it would mark the weakest quote on record for the year and could feed expectations of another gradual upward drift in the exchange rate.

07 What to watch

• Country risk: The 566-point reading and its daily direction now act as a quick barometer of confidence in the Milei trade.
• Bank shares: Supervielle, Galicia and Macro led Wednesday’s fall; whether they stabilise will signal if profit-taking is over.
• YPF and Vaca Muerta: The gas-export project’s funding progress is a central pillar of Argentina’s energy story.
• Peso at 1,516: A close above the 52-week high of 1,516 per dollar would be a new signal for FX markets.
