Argentina is conducting a comprehensive overhaul of its antitrust laws, including merger control. A draft bill underwent a public consultation process in 2016.

The most notable proposed change with regard to merger control is the introduction of a suspensive, premerger regime to replace the current postclosing system. In addition, the reform foresees new, more inflation-resistant thresholds, new decision timeframes, and a fast-track mechanism. The reform is intended to bring the regime more in line with international best practices and to speed up clearance procedures, which currently can take up to two years or more.

The reform bill is currently pending before the Argentinian parliament, and the timeframe for adoption and implementation has yet to be clarified.
