EU policymakers have finally moved the long‑awaited EU‑Mercosur free‑trade agreement into provisional force, despite fierce protests from farmers in France, Belgium, Poland and elsewhere. The decision follows more than two decades of negotiations and a recent push to make the impact of such deals clearer at the regional level.

Regional modelling shows limited but positive effects

The European Spatial Planning Observation Network (ESPON) released its STARTER project report in early 2025, offering the first comprehensive assessment of how the Mercosur pact could reshape wages across 296 European regions. Unlike the Commission's 2011 study, which focused narrowly on agriculture, the new analysis looks at overall welfare, measured in changes to real wages, and maps the effects far beyond national averages.

On average, the pact is projected to raise real wages by less than one percent. While the figure sounds modest, the benefit is spread across almost every EU region, meaning that most workers could see a small improvement in purchasing power. The most pronounced gains are expected in parts of Croatia, Romania, Bulgaria, southern Italy, Spain and Portugal, essentially the southern belt of the Union.

Conversely, the study flags a few areas where the agreement could drag wages down. Basilicata in Italy and certain regions of Greece are among the handful that may experience a negative impact, albeit also modest in scale.

Why the regional split matters

Farmers and agrifood producers have long warned that an influx of cheaper meat, dairy and other products from Brazil and its Mercosur partners could undercut EU agriculture. Those concerns are not uniform; they depend heavily on the structure of local economies. Regions heavily reliant on livestock or dairy farming are more vulnerable, while those with diversified industrial bases may benefit from cheaper inputs and new export opportunities.

The Mercosur deal includes safeguard clauses designed to protect sensitive sectors, but critics argue that the mechanisms are insufficiently detailed. Without granular data, it is difficult for regional authorities to gauge whether the safeguards will kick in before damage occurs.

"We need evidence at the NUTS‑3 level to decide if a safeguard is justified," said a spokesperson for a French farmers' union, who asked to remain anonymous. "Otherwise we are left guessing whether the deal will destroy livelihoods in our valleys."

Trade unions across the continent echo the call for more precise information. The European Trade Union Confederation (ETUC) has urged the Commission to publish the regional impact data as soon as it becomes available, arguing that workers deserve to know whether their wages are likely to rise or fall under the new rules.

Political pressure and the road ahead

National governments cannot simply opt out of an EU‑wide agreement once it is ratified, because the single market guarantees free circulation of goods. This means that if Mercosur products enter the Union duty‑free, they can move unhindered across borders, preventing any one member state from re‑imposing tariffs on its neighbours.

That legal reality has intensified the debate in the European Parliament, where the final vote on the agreement is expected later this year. Lawmakers will be able to draw on the ESPON findings to argue for or against a full ratification, and to press for stronger regional safeguards where needed.

Spain's prime minister, Pedro Sánchez, used a recent visit to China to highlight the need for openness in trade talks, but he also warned that any new deal must be balanced against the interests of vulnerable regions. "We cannot sign away the future of our farmers without proof that the benefits outweigh the costs," he told reporters in Madrid.

Meanwhile, the European Commission has signalled that it will commission follow‑up studies once the provisional period ends, to monitor actual wage changes and market flows. Those data will be crucial for the Parliament's final decision and for any future renegotiations.

Implications for European workers and households

For most households, a sub‑one‑percent rise in real wages is unlikely to be a game‑changer. However, in regions where the increase is concentrated, even a small boost can help offset rising living costs, especially in the south where inflation has been stubbornly high.

In contrast, the few regions projected to lose ground may see a slight squeeze on disposable income, potentially prompting calls for targeted support measures such as transition funds or sector‑specific subsidies.

Consumer groups have also weighed in, noting that cheaper imports could lower food prices, benefitting low‑income families. Yet they caution that price reductions should not come at the expense of food safety or animal‑welfare standards, issues that have already sparked bans on Brazilian meat and dairy over health concerns.

Overall, the ESPON report underscores the need for a more nuanced trade policy that recognises Europe's economic diversity. By mapping benefits and drawbacks region by region, policymakers can design complementary measures, from investment in upskilling to sectoral aid, that ensure the gains of free trade are shared more equitably.

As the provisional phase of the EU‑Mercosur deal unfolds, the coming months will reveal whether the promised modest wage uplift materialises and whether the safeguards are enough to protect the most exposed communities. The evidence gathered will not only shape the final parliamentary vote but could set a precedent for how future EU trade agreements are evaluated against the lived realities of European workers.
