The 14th Bienal do Mercosul, which Fonseca is curating, has been rescheduled for next March–June due to the devastating floods that hit the southern Brazilian state of Rio Grande do Sul earlier this year, affecting several exhibition venues. The postponement provided some unexpected respite from a very busy year. In October Fonseca opened Fullgás at CCBB Rio de Janeiro, a survey of visual art in Brazil during the 1980s featuring approximately 300 works by over 200 artists. Fonseca was also touring Frieze London in October, as part of a purchasing committee for Tate, while acting as a curatorial adviser to the Prospect 6 triennial in New Orleans, which opened in November. Fonseca is now gearing up for Counterpublic in 2026, the citywide exhibition in St Louis that has appointed him as part of a five-strong curatorial committee. Fonseca has a day job, too. As curator of modern and contemporary Latin American art at Denver Art Museum, he opened an exhibition in April of Chilean artist Sandra Vásquez de la Horra’s fantasy-inflected paintings and drawings.
