Today’s Focus
Argentina’s stock market closed lower on Wednesday, with the main Merval index down 0.94% at 2,969,545 points. The peso also slipped, easing 0.12% to 1,516 per US dollar, leaving the currency near the weakest level of its 52-week range.
Banking shares did most of the damage: Banco Supervielle fell 3.0%, Grupo Galicia dropped 2.9% and Banco Macro lost 2.7%. Energy group YPF was the standout gainer, rising 1.6% on continued hopes around the Vaca Muerta gas-export plan.
The moves reflect a market that is still pricing in broad support for President Javier Milei’s reform agenda, but with growing caution now that country risk has climbed for eight straight sessions to 566 points.
What matters today. The reform trade’s momentum is cooling, with banks leading a fresh pullback even as energy names like YPF hold up.
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.
The scale of Wednesday’s pullback was modest, a sub-1% decline on the Merval, and profit-taking in the banks, which have been among the biggest winners of the Milei trade, fits a consolidation pattern rather than a retreat. The peso’s 0.12% slippage to 1,516 per dollar is also within recent ranges, not a fresh slide.
Still, the backdrop is getting slightly less friendly: country risk has risen for eight consecutive sessions to 566 basis points, and global equities fell overnight, with the S&P 500 down 0.75%. The variable to watch is whether country risk keeps climbing, which would pressure Argentine dollar bonds and could spill over into domestic equities.
02 The day’s numbers
| Measure | Level | Change | Read |
|---|---|---|---|
| Merval | 2,969,545 | −0.94% | Profit-taking in banks; still near record highs |
| USD/ARS | 1,516 | +0.12% | Peso slips near the weak end of its 52-week range |
| 52-week range | 1,348–1,516 | — | Dollar sits right at the top of the range |
| S&P 500 | 7,706 | −0.75% | Soft US session added to the cautious tone |
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. Rio Times · Live Market Intelligence

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
| Driver | Level / Move | Change | Note |
|---|---|---|---|
| Banco Supervielle | SUPV | −3.0% | Largest fall among major local names |
| Grupo Galicia | GGAL | −2.9% | Turnover $11m, heaviest bank flow |
| Banco Macro | BMA | −2.7% | Banking weakness continues |
| BBVA Argentina | BBAR | −2.6% | Financials led the decline |
| YPF | YPFD | +1.6% | Top-traded with $14m; Vaca Muerta hopes intact |
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
| Index | Country | Change |
|---|---|---|
| Merval | Argentina | −0.94% |
| Ibovespa | Brazil | −0.86% |
| IPC | Mexico | −0.28% |
| IPSA | Chile | +0.20% |
| COLCAP | Colombia | +0.92% |
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.
