A New Era for Argentina's Capital Markets
By Carolina Zang, Partner at ZBV Abogados. Capital Markets and Corporate Finance specialist.
For more than three decades, I have advised clients in the Argentine capital markets, including some of the country's most significant IPOs and follow-on offerings. The package of regulations recently approved by the Argentine Securities Commission (CNV Resolutions No. 1145–1150/2026) represents the most significant overhaul of the regulatory framework since the enactment of Capital Markets Law No. 26,831.
I say this with genuine enthusiasm, but also because I know firsthand the real cost of the system these reforms replace.
The One Thing Capital Markets Cannot Afford: Time
Whenever a company decided to access the capital markets, one of the first things we, as lawyers, had to tell our clients was: "The process will likely take six months—or even longer."
This was not an exception. It was the natural consequence of a regulatory model under which every offering required prior review and approval by the CNV before reaching investors.
In theory, this ex-ante review was designed to protect investors. In practice, it often produced the opposite effect. Only companies able to absorb the cost—in time, professional fees and uncertainty—could realistically access the market. Many mid-sized businesses simply could not.
I have seen issuers abandon transactions because the market window closed while waiting for regulatory approval, and CFOs forced to explain to their boards why the timing of an issuance ultimately depended on an administrative file rather than on market conditions.
What Has Really Changed
This is much more than a regulatory update—it is a change in philosophy.
The previous framework was based on prior authorization. The new regime adopts a filing-based approach: issuers file the required documentation, assume responsibility for its accuracy, and access the market without waiting for formal approval.
Regulatory oversight has not disappeared. The CNV retains its supervisory, enforcement and sanctioning powers. What changes is the timing—and the allocation of responsibility. Issuers, underwriters and legal advisers now bear greater ex-post responsibility for the quality and completeness of the information disclosed.
This is how mature capital markets operate. It also allows smaller companies to access financing with the same procedural efficiency previously available only to frequent issuers.
For offerings of up to 100 million UVAs (approximately US$130–140 million), authorization becomes effective automatically upon filing. Above that threshold, the same streamlined regime applies when securities are offered exclusively to qualified investors—a category whose eligibility threshold has also been significantly reduced.
Investor Protection Has Not Been Weakened
One of the inevitable questions is whether eliminating prior regulatory approval diminishes investor protection.
In my view, it does not.
Disclosure obligations remain equivalent to—or in some cases more demanding than—those under the General Regime. Issuers continue to assume full regulatory, civil and criminal liability for the contents of their prospectuses.
What has been removed is not the standard of disclosure, but unnecessary bureaucracy.
Where underwriters do not retain independent legal counsel, investors must be expressly informed. Ultimately, investor protection depends on the quality, accuracy and accountability of the information provided—not on how long a regulator takes to review the documentation.
What This Means for the Real Economy
For years, discussions about Argentina's capital markets have focused primarily on large issuers and sophisticated financial instruments.
This reform broadens the conversation.
Agribusiness companies seeking to securitize commodities, real estate developers, manufacturing businesses looking for working capital—each now has a far more practical path to market.
The reform also expands the use of tokenization across all securities under automatic regimes and extends the regulatory sandbox through the end of 2027, reinforcing Argentina's commitment to financial innovation.
A Reform That Also Challenges Us
It would be easy simply to celebrate these reforms.
But they also demand more from us as legal advisers.
Under the previous system, prior regulatory review provided an implicit safety net. That no longer exists.
Lawyers involved in preparing offering documentation will assume greater responsibility for its quality, requiring more rigorous due diligence and a professional culture that understands that automatic filing is not a shortcut—it is a model built on accountability.
That is precisely how sophisticated capital markets have functioned for decades.
And that is exactly why this reform should be welcomed.
Thirty years ago, Argentina had the opportunity to become a regional financial hub. That ambition was never fully realized, for reasons extending well beyond regulation.
These reforms do not solve every structural challenge facing the market.
But they do remove one of its most tangible—and most correctable—obstacles.
