Buenos Aires stock market: Merval ends bruising week as Milei labor reform clears Senate

Buenos Aires, Feb 28, 2026, 06:20 ART — Market closed.

  • Friday saw the S&P Merval slide 4.1%, wrapping up the week down roughly 8%.
  • After markets closed, the Senate gave final approval to the Milei-backed labor reform. Monday will put it to its first test.
  • March inflation figures are up next on traders’ radar, likely the key local trigger.

Argentina’s S&P Merval index dropped 4.1% on Friday, ending the session at 2,642,105.5 points and wrapping up the week with an 8% slide. February didn’t offer much relief either; the index shed around 17.4% in pesos for the month, using January’s final close as a reference. Investing.com

Traders will have a new political headline to weigh at the open. Argentina’s Senate pushed President Javier Milei’s labor reform through to final approval late Friday, clearing a key hurdle after weeks marked by heated debate and street protests. Reuters

Why this is hitting now: the vote came in after Buenos Aires wrapped for the day, leaving traders without a straightforward way to price it in. For investors, this law has become a barometer for Milei’s ability to drive his bigger agenda through Congress. The selloff in local stocks has only added to the choppiness, making positioning more volatile.

Global risk appetite remains tepid. On Friday, world equities slipped, with investors contending with lofty valuations and the disorienting impact of AI, while geopolitical frictions drove oil prices higher. That combination has made life tougher for riskier pockets of emerging markets. Reuters

Labor reform plans would loosen rules around hiring and work hours, opening the door to 12-hour shifts instead of the traditional eight. Another controversial piece: employers would start paying into a new severance fund, redirecting money now set aside for the national pension system. Critics warn that move could drain pension resources.

Details like these are important for listed companies. With a severance fund, lump-sum payouts on layoffs get swapped for a pooled setup. That alters both firing costs and cash-flow timing. Investors are eyeing how quickly companies adjust, plus any legal battles that surface.

Some foreign investors see the reform as progress toward making Argentina more investable, albeit with caveats. “The labor legislation is ‘a big deal,’” said Benjamin Gedan, director of the Latin America program at the Stimson Center, in comments cited by Barron’s. Barron’s

The risk sits squarely beside the bull case. Unions have already proven their ability to mobilize. Any attempt to tweak strike rules or use pension-linked funds? That could stiffen opposition and drag out implementation—even if the law clears.

Argentina’s February CPI lands March 12, per the INDEC calendar, and traders aren’t missing it. The focus: signs of disinflation and any clues about where domestic rates or the peso could be headed.

Trading resumes Monday, March 2. The first thing traders will be watching: fallout from the labor reform vote. After that, attention shifts to the March 12 inflation figure—numbers like that can flip the script in Buenos Aires in a hurry.

Buenos Aires stock market: Merval ends bruising week as Milei labor reform clears Senate

Buenos Aires, Feb 28, 2026, 06:20 ART — Market closed.

  • The S&P Merval fell 4.1% on Friday, ending the week about 8% lower.
  • Milei-backed labor reform won final Senate approval after the close, setting up Monday’s first test.
  • Traders are lining up March inflation data as the next local catalyst.

Argentina’s benchmark S&P Merval index closed down 4.1% on Friday at 2,642,105.5 points, capping a weekly decline of about 8%. The index finished February down roughly 17.4% in pesos, based on the last close of January. Investing.com

The next session will open with a fresh political catalyst on the tape. Argentina’s Senate approved President Javier Milei’s labor reform late on Friday, giving it final clearance to become law after weeks of tense debate and protests. Reuters

Why it matters now: the vote landed after the Buenos Aires close, so the market did not get a clean shot at pricing it. Investors are using the law as a read on whether Milei can keep pushing his broader agenda through Congress, even as the selloff in local shares has made positioning more jumpy.

Global risk appetite is not helping. World equities edged lower on Friday as investors weighed high valuations, the disruptive pull of AI, and geopolitical tensions that pushed oil prices higher, a backdrop that has been awkward for riskier corners of emerging markets. Reuters

The labor reform is aimed at easing hiring and other rules and allowing the standard workday to be extended from eight to 12 hours, among other changes. It also creates an employer-financed severance fund using contributions currently earmarked for the national pension system, a point opponents say could squeeze pension resources.

For listed companies, the mechanics matter. A severance fund is meant to replace traditional lump-sum payments when workers are laid off, shifting the cost toward a pooled system that can change cash-flow planning and firing costs. Investors will watch for how fast firms can adapt — and how many court challenges turn up.

Some overseas investors have framed the reform as a step toward a more investable Argentina, though not a straight line. “The labor legislation is ‘a big deal,’” Benjamin Gedan, director of the Latin America program at the Stimson Center, was quoted as saying. Barron’s

The risk case sits right next to the bull case. Unions have already shown they can mobilize, and any push to change strike rules or tap pension-linked funds could harden resistance and slow implementation, even with the law passed.

On the calendar, traders have a clear date circled: Argentina’s CPI report for February is scheduled for March 12, according to INDEC’s dissemination calendar. That release will be watched for whether disinflation is holding, and for what it means for domestic rates and the peso mood.

Markets reopen on Monday, March 2. First up is the reaction to the labor reform vote; next up is that March 12 inflation print, the kind of number that can reset the week in Buenos Aires fast.
