Delgado held several important positions in Ecuador's financial sector, including Risk Manager at the National Financial Corporation (CFN) during the governments of Abdalá Bucaram and Jamil Mahuad.

Delgado's tenure at the Central Bank came to an abrupt end in December 2012 when he resigned after admitting to falsifying his economics degree from the Pontifical Catholic University of Ecuador.

[1] This scandal not only led to his resignation but also resulted in the revocation of his master's degree in administration from INCAE Business School.

[2] This conviction stemmed from an illicit loan of $800,000 granted to Argentine businessman Gastón Duzac in 2011, during Correa's presidency.

Additionally, in 2019, Ecuador's National Court of Justice sentenced Delgado to five years in prison for illicit association and ordered him to repay approximately $788,000.
