The world's largest wealth manager has a new leader for its Latin America and Caribbean regions.

UBS Wealth Management Latin America and Caribbean has appointed a new leader in the shape of Alexander G van Tienhoven, a former top-ranking manager at Citi, where he held roles including at its private banking arm.

He will be based in Zurich and will report, as the LatAm group's managing director, to Paul Raphael, who leads the division's global emerging markets business.

Van Tienhoven takes over from Gabriel Castello, who took the helm of WM Europe International at UBS on March 1, reporting to Jakob Stott, head of WM Europe.

The new LatAm/Caribbean boss at UBS is widely regarded as one of the most senior and experienced wealth management executives in the Latin American market, UBS said. He joins from Citi, where he had a 27-year career, most recently as chief executive Latin America for Citi Wealth and Investment Management. He previously acted as the region president for Citigroup Private Bank in Latin America.

He will work with Rick Gonzalez, head of UBS Wealth Management Americas International.

His appointment is effective as of March 30.

The role means van Tienhoven is responsible for a region covering the following countries: Brazil, Mexico, Bahamas, Argentina, Uruguay, Paraguay, Chile, Peru, Bolivia, Venezuela, Ecuador, Colombia, Guyana, Central America and the Caribbean.

In his previous berth as chief executive of Citi Wealth and investment management in Mexico and Latin America, he was responsible for Citi Private Bank, Citigold Private Client, Banamex Banca Privada & Patrimonial, Citigold International and International Personal Banking. He was also responsible for the asset management, brokerage, retirement, insurance and the trust businesses.

From 2000 to 2015, he was managing director and general manager of Citi Private Bank, Mexico. In 2002, van Tienhoven was given the mandate to integrate the Banamex Private Bank into the Citi Private Bank.

From 1996 to 1999, he served as vice president and general manager of Citibank Portugal and was a member of the management committee of Citibank Spain.
