Macron pushes EU-wide under-15 social media ban as platforms face scrutiny

French President Emmanuel Macron has asked European Commission President Ursula von der Leyen to prepare a “European legislative act” that would ban children under 15 from using social media, according to AFP, in a move that could sharpen regulatory pressure on major platforms and draw close attention from London markets.

The request was set out in a letter dated August 29, which AFP said it reviewed on Monday, September 7. Macron urged Brussels to move beyond national efforts and establish a harmonised European framework, after France’s Constitutional Council blocked a domestic version of the measure on August 14.

The French constitutional body said the provision violated freedom of expression. That ruling was a setback for Macron, Reuters reported, and forced Paris to look again at how any restriction on minors’ access to platforms such as TikTok, Instagram and Snapchat could be drafted in a way that satisfies both French constitutional standards and European Union law.

“It is now essential to go further and harmonise this provision through a new European text,” Macron wrote in the letter to von der Leyen.

For UK and European business, the proposal matters beyond French domestic politics. A binding EU-wide rule would affect the compliance models, user-verification systems and legal risk profile of large social media companies operating across the bloc. Although the UK is no longer an EU member, British investors, advertisers, data providers and listed technology suppliers remain exposed to European regulatory decisions through clients, revenues and market sentiment.

EU regulation moves back into market focus

Macron’s appeal comes at a time when European governments are weighing children’s online safety against speech rights, privacy concerns and the commercial interests of digital platforms. Any European Commission proposal would likely require detailed work on age verification, platform liability and enforcement, all of which could influence costs for companies serving EU users.

In London, investors typically watch EU digital policy because regulatory decisions can affect global platform valuations, advertising markets and sentiment toward technology shares. The immediate sterling impact from Macron’s request alone is likely to be indirect rather than mechanical, because the proposal remains at the political and legislative stage. But the direction of travel could matter for UK-listed firms tied to digital advertising, identity verification, online safety compliance or European technology services.

For the pound, the issue is less about a single French initiative and more about the broader regulatory climate facing European consumer technology. A tougher EU line on social media access for minors could encourage similar debate in Westminster or influence UK regulatory expectations, particularly where British businesses sell into the single market or depend on platform advertising revenues. That would put compliance spending, user growth assumptions and advertiser reach back into focus for analysts.

The proposal may also be watched by companies in London that specialise in digital identity and age assurance. If Brussels were to pursue an EU-level act, platforms would need legally robust ways to determine whether users are under 15. That could create demand for verification systems, but it would also raise privacy and implementation questions for providers operating under European data protection rules.

French setback pushes Macron toward Brussels

Macron, who is due to leave office after elections in April 2027, has said he hopes to “find a way forward” in the coming months through a revised national legislative act that would be “in line with EU law and the Constitution”. After the Constitutional Council ruling, he instructed Prime Minister Sebastien Lecornu to prepare a new draft law described as legally flawless.

The French bill followed a December 2025 report by the country’s health watchdog warning of harmful effects on children from platforms including TikTok, Instagram and Snapchat. The report cited potential risks such as lower self-esteem and possible increases in self-harm, suicide and drug use. According to the cited statistics, every second teenager spends between two and five hours a day on a smartphone, and 58% use phones to access social networks.

The initiative gathered momentum after Macron made the ban a central part of his domestic agenda in his final year in office. The move also places France among governments seeking more assertive controls over young people’s access to online platforms, even as courts and constitutional bodies test the limits of such interventions.

Australia has already taken a tougher path. In December 2025, people under 16 were blocked from accessing most social media platforms there. Macron’s push for a European act suggests Paris wants the EU to avoid a patchwork of national rules and instead create a single framework that platforms cannot easily sidestep by adjusting terms country by country.

For Brussels, the political challenge will be to design any proposal so that it can withstand scrutiny over freedom of expression while addressing child welfare concerns. For companies and investors, the practical challenge would be understanding how an under-15 ban could be enforced at scale without creating new privacy liabilities or undermining user engagement across European markets.

The UK angle will remain commercially important even if the legislation is drafted inside the EU. London’s markets are sensitive to regulation that reshapes the earnings outlook for global technology groups, advertising intermediaries and compliance vendors. A European social media age ban would therefore be read not only as a children’s safety measure, but also as another sign that the region’s digital rulebook is becoming a central business risk for platforms operating on both sides of the Channel.
