The Balearic Islands, including popular tourist destinations like Ibiza and Majorca, are facing significant challenges due to overtourism, particularly concerning the availability of affordable housing for local residents. In response to these issues, the Partit Socialista de les Illes Balears (PSOE) is set to propose a cap on tourist numbers, aiming to limit annual visitors to 17.8 million. This figure reflects the number of visitors recorded in 2023 but is a response to the rising levels of tourism, which reached over 19 million in 2025.

The proposal is part of broader efforts by the PSOE to combat the detrimental effects of mass tourism in the region, which have raised concerns among locals and policymakers alike. Iago Negueruela, a prominent figure behind the proposal, previously suggested an even stricter cap of 16.5 million, emphasizing that this number should not be exceeded to protect the islands' cultural and social fabric. Such caps could drastically change the tourism landscape, focusing on sustainability and long-term benefits for the local community.

If enacted, these measures could have significant implications for the tourism industry, local businesses, and the overall economic landscape of the Balearic Islands. While such restrictions may deter some tourists, proponents argue that it could improve living conditions for residents by ensuring that adequate resources are available for both locals and visitors. This proposal raises important questions about how best to balance the economic benefits of tourism with the needs of local populations and the preservation of the islands' natural and cultural heritage.
