José Yves Limantour Marquet[4] (Spanish pronunciation: [xo'se ˈiβ(e)s limanˈtuɾ]; 26 December 1854 – 26 August 1935) was a Mexican financier who served as Secretary of the Finance of Mexico from 1893 until the fall of the Porfirio Díaz regime in 1911.

As the secretary of finance, Limantour established the gold standard in Mexico, suspending free coinage of silver, and mandating only government coins be used.

[5] He secured the national debt in 1899 with a consortium of foreign banks, and at the time of the outbreak of the Revolution, Mexico was on strong financial basis.

After the death of Matías Romero Rubio in 1895, Limantour was considered the political leader of the technocratic advisers to President Díaz known as científicos ("the scientists"), who were highly educated and wanted expanded intellectualism and prosperity in Mexico.

They exchanged letters, but they rarely met during their first months living in Paris, as Díaz resented reports that Limantour had attempted to negotiate his eventual reincorporation in the federal cabinet with the revolutionary leader, Francisco I. Madero,[11] Limantour had strong ties with the Madero family, as he had served as their trade agent in Mexico City.

In the end, however, Madero chose his uncle Ernesto, an experienced banker from Coahuila, as his secretary of Finance and Díaz and Limantour were eventually reconciled.
