Argentina Markets: Merval & the Peso — July 25, 2026

01 The session in one read

The Merval fell 1.07% to 3,283,854 on Thursday, as Argentine stocks failed to extend their recent rally. The peso, meanwhile, slipped to an official rate of 1,496 against the dollar—marking the very top of its 52-week trading band.

Financial heavyweights bore the brunt of the selling. Grupo Financiero Galicia, the country’s largest private bank by market value and a barometer of the high-octane reform trade, gave back 0.7% on the session. Energy giant YPF, the state-controlled oil and gas producer, lost 0.6%.

The moves came in a session largely devoid of major corporate news, leaving global cues—which were muted—and month-end portfolio adjustments to guide the tape. The weakness in Argentina coincided with a rough day for Brazilian equities, where the Ibovespa tumbled 1.52%.

For foreign investors tracking the ‘Milei reform trade’, the day served as a reminder that a gradually devaluing peso and high nominal stock prices naturally invite bouts of profit-taking, especially after lengthy bull runs in local-currency terms.

02 The day’s numbers

The US dollar strengthened by 0.47% against the Argentine peso, closing at 1,496. This matches the 52-week high for the currency pair, underlining the steady pace of controlled devaluation that the Milei administration is using to keep the real exchange rate competitive.

The Merval’s dip was modest in the context of its long-term climb. While the exact 52-week high and low levels were not quoted in the session scan, the index remains at elevated levels that have repeatedly tempted traders to lock in profits, particularly when the peso’s gradual slide eats into total dollar returns over short holding periods.

03 Why it moved — profit-taking hits the reform trade

The Merval’s decline was a textbook case of buyers taking a breather. For months, Argentine bank stocks have skyrocketed on the promise of President Milei’s sweeping deregulation and fiscal austerity programme—a bet that a more normal economy will eventually unleash huge lending growth and corporate activity.

On Thursday, that trade simply took a rest. Grupo Galicia slid 0.7%, and while the move was small, its hefty $15 million in local turnover signalled that large institutional investors were actively trimming positions. Similarly, energy stocks like Pampa Energía—which sank a sharper 2.0%—were pressed lower as the peso’s steady crawl to a fresh 52-week low reminded traders of the constant currency headwind.

Global markets offered no diversion. The S&P 500 was virtually flat on the day, meaning Argentine equities had to stand on their own domestic merit. With no major policy announcements from Buenos Aires—and country risk hovering around recent ranges without cracking significantly lower—the path of least resistance for the index was a moderate step downwards.

It is crucial to understand that for the local portfolios that drive the Merval, the peso’s 0.47% daily decline against the dollar is not a side note; it is the main story. Operating under a crawling peg system, every trading day that the peso ticks weaker, the hurdle rises for a foreign investor to emerge with a positive return once they convert their peso-denominated stock gains back into dollars.

04 The day’s movers

Volume leadership belonged firmly to the financial sector. Grupo Galicia saw $15 million in turnover and Banco Macro similarly softened, confirming that profit-taking was concentrated where the year’s biggest gains had been made. In energy, YPF gave back 0.6% on solid $6 million volume, though independent producer Vista Energy bucked the trend with a tidy 1.0% gain.

The session’s most extreme moves came from the CEDEAR market—local certificates that track US-listed shares and ETFs. Disney’s CEDEAR soared over 21%, a move that almost certainly reflects a corporate action or ex-dividend effect on the underlying US listing. Conversely, a 2.1% fall in Tesla’s CEDEAR and a 1.3% rise in Google parent Alphabet’s CEDEAR were pure reflections of overnight US tech trading, not Argentine sentiment.

05 The regional scoreboard

Latin America was a mixed bag. The sharpest move came from Brazil, where the Ibovespa—the main Brazilian stock index—dropped 1.52%, suggesting a broader regional caution in the heavyweight market. In contrast, Mexico’s IPC inched up 0.21% and Chile’s IPSA added a mild 0.31%, demonstrating little contagion from Argentina’s retreat.

Colombia’s COLCAP fell 0.38%, rounding out a session where commodity-linked Andean economies took cues from individual local developments rather than a single regional theme. For Argentina, the main driver remained entirely domestic: the local interplay between reform hopes, profit-taking, and the peso’s managed crawl.

06 The technical picture

The Merval’s decline from what participants have described as ‘elevated territory’ did little technical damage, but it put the 3.2 million level in focus as the first important support zone for short-term traders. Because the scan could not specify an exact 52-week high, the visual chart posture nonetheless feels like an index consolidating near the upper end of its long-term range.

For the peso, the 1,496 print is technically significant. It represents the very top of the 52-week band and functions as the absolute high-water mark for dollar strength under the current crawling peg framework. A breakthrough above this level—should the central bank opt for a slightly faster crawl or a micro-devaluation—would open the door to dollar/peso levels above 1,500 for the first time in the cycle, a move that would reverberate through equity and bond pricing. For now, the technical posture of the peso is one of orderly, managed weakness.

07 What to watch

• Peso crawl pace: Watch whether the USD/ARS rate accelerates beyond 1,500, as a faster crawl would squeeze dollar-denominated stock returns and potentially stoke inflation expectations, unsettling the entire reform trade.
• Banking sector flows: Galicia and Macro have been the engines of the 2025-26 rally; sustained daily volume above $10m on down days would signal more serious institutional distribution, not just a gentle profit-taking pause.
• Country risk premium: If Argentina’s country risk—the extra yield investors demand to hold its bonds—ticked lower, it didn’t show up in equity strength; keep an eye on the JP Morgan EMBIG spread for a divergence that could signal the next leg in either stocks or bonds.
• Brazilian contagion: The Ibovespa’s sharp 1.52% fall is a reminder that regional risk appetite can sour quickly; if the Brazilian real weakens sharply alongside the selic rate decisions, it could spill into Argentine assets via broader outflows from Latin American funds.

Frequently Asked Questions

What is Argentina’s Merval index?

The Merval—short for Mercado de Valores—is the primary stock market benchmark of Argentina, operated by Bolsas y Mercados Argentinos (BYMA). It tracks the performance of the most liquid domestic companies trading in Buenos Aires, with heavy weightings in banks and energy firms.

Why did the Argentine peso weaken to 1,496 per dollar?

The peso is managed under a crawling peg system where the central bank allows a controlled, gradual depreciation. The move to 1,496—a 52-week high—is part of this deliberate policy to maintain export competitiveness, rather than a sudden market shock.

What is the ‘Milei reform trade’?

It is the term used by investors to describe buying Argentine assets—especially bank and energy stocks—in anticipation that President Javier Milei’s radical deregulation, spending cuts, and market-friendly policies will normalise the economy and boost corporate profits dramatically.

What are CEDEARs?

CEDEARs are Argentine Depositary Receipts that trade on the Buenos Aires exchange. They allow local investors to buy shares of foreign companies—like Google (GOOGL) or Tesla (TSLA)—in pesos. Their price moves are driven primarily by the original US stock price and the peso/dollar exchange rate.
