After more than 25 years of negotiations, the free trade agreement between the European Union (EU) and the South American bloc Mercosur reached a decisive stage in its development in 2026, with political progress and institutional controversies shaping its implementation.
Mercosur includes Argentina, Brazil, Paraguay, and Uruguay, a vast trade area with the potential to involve more than 700 million people and a significant role in the global economy, while the EU represents one of the world’s leading trading partners.
What the Agreement Includes
The EU–Mercosur agreement is a multilateral trade and economic cooperation pact aimed at gradually reducing tariffs and non-tariff barriers on more than 90% of trade between the two regions. It covers goods and services, rules of origin, sanitary and phytosanitary standards, investments, public procurement, and technical cooperation, with the goal of creating one of the largest free trade areas in the world.
If fully ratified, the treaty would reduce tariffs on products such as automobiles, machinery, pharmaceuticals, and agricultural goods, stimulating exports and investments between the two regions.
Formal Steps Taken in 2026
Signature and initial approval: the agreement was officially signed on January 17, 2026, after the EU Council gave the green light to conclude the deal, supported by a qualified majority of member states.
Ratifications in Mercosur: Uruguay and Argentina became the first Mercosur member states to ratify the agreement in their national parliaments, a historic step that unlocked the start of the operational phase.
Progress in Brazil: the Brazilian Chamber of Deputies approved the agreement, and the final vote of the Senate is now awaited to complete national ratification.
Provisional Application and Institutional Context
One of the main developments is the decision by the European Commission to proceed with the provisional application of the agreement, even without the formal approval of the European Parliament. This mechanism, already used in other trade agreements, allows certain provisions of the agreement to enter into force before full ratification.
The Commission justified this choice with the urgency of strengthening the EU’s economic resilience and creating new trade opportunities in a context of global tensions.
However, this procedure has sparked strong institutional criticism:
European Parliament: it has requested a legal opinion from the Court of Justice of the European Union on the legality of the agreement and the possibility of applying it without a parliamentary vote.
Political leaders and farmers: in countries such as France and Poland, the agreement is seen as a potential threat to the agricultural sector and food safety standards, with criticism directed at the decision to bypass standard democratic processes.
Economic and Trade Implications
According to estimates from the European Commission, the agreement could generate significant economic benefits by 2040, including:
- an increase in EU GDP of tens of billions of euros
- growth in European exports to Mercosur
- increased employment linked to new trade flows
Reciprocal access to markets for industrial goods and food products should reduce costs for companies and expand investment opportunities in key sectors such as automotive, machinery, and agriculture.
Outlook and Next Steps
For the agreement to fully enter into force, the following steps are required:
- Full ratification by the four Mercosur states (Brazil and Paraguay still need to complete their legislative processes).
- Final approval by the European Parliament, after the opinion of the Court of Justice.
If provisional application proceeds, many trade chapters could already become operational, creating new trade routes and conditions for European and South American entrepreneurs and businesses by 2026.
In conclusion, the EU–Mercosur agreement represents a historic step toward the integration of two major economic areas, with strong potential for trade growth and cooperation. However, the institutional path remains complex, involving ratifications within Mercosur, decisions regarding provisional application in the EU, and political challenges linked to sectoral interests.
The coming period will be crucial in determining how and when this ambitious agreement will translate into concrete benefits for businesses, workers, and consumers in both regions.
