On October 12, 2016, Queen Maxima was in her native Argentina as part of her role as the UN Secretary-General's Special Advocate for Inclusive Finance. She had several events on her agenda while there including meeting the President of Argentina, Mauricio Macri, at Casa Rosada. Additionally, she returned to her alma mater, The Pontifical Catholic University of Argentina. Her parents were in the audience for this appearance.

For her meeting with President Macri (and Argentina Minister of Economy Alfonso Prat-Gay at a separate location), Maxima wore a red Natan blouse and a tartan Natan skirt with a Steltman bracelet and red Gianvito Rossi heels. Her matching red purse was also by Natan. 

When she returned to her alma mater to give an exclusive speech to the students regarding financial inclusion for development, the Queen wore a green animal print dress by Givenchy, Cartier watch, Steltman bracelet, a pair of large diamond stud earrings and Christian Louboutin black heels. She carried a black Chanel medium sized bag. 

For both days, some of her jewlery still stands as UFO.

This was Queen Maxima's first time visiting Argentina as the UN Secretary-General's Special Advocate for Inclusive Finance. About the trip, the Royal House of the Netherlands said in a press release, “She will speak about the government’s plans to develop a national strategy for inclusive finance. Better access to financial services can improve people’s economic development.”

According to Royal Central, "They cited the World Bank Group’s statistics that only half of adult Argentinians have a savings account, and most monetary transactions are done through cash. Because of this and the lack of proper financial records, it is difficult for small businesses to be granted a loan to expand their businesses."

Before returning to the Netherlands, she made sure to thank her home country for warmly welcoming her back in a press conference with Vice President Gabriela Michetti regarding her visit.
