In the early 1990s, Buchan started his investment banking career. From 1992 to 1997, he was a Vice President at Merrill Lynch. There he specialized in corporate finance, and mergers and acquisitions in the financial services sector in Latin America, the United States and Europe. After working at several financial firms, Buchan in 2001 founded Hunter Global Investors in New York City. In 2007, Hunter had approximately US$ 1.5 billion assets under management. After beating U.S. stocks by 46 percent between 2001 and March 2011, Buchan closed one of his funds in December 2011 due to losses stemming from the European debt crisis, and returned money to investors. He converted Hunter Global Investors into a family office to manage his family's assets, and continues to manage two funds, which invest in a range of asset classes globally, including real estate. He has traveled, lived, and/or done business in more than 50 countries for almost four decades.
Philanthropy
The Buchan Excellence Fund
In 2011, Buchan established The Buchan Excellence Fund in UNC-CH's Department of Romance Languages and Literature, "the largest single endowment at Carolina dedicated to support faculty, graduate students and undergraduates in Spanish languages, literature and culture." The fund has helped students and professors further their research on topics in Spanish culture and linguistics, and also enabled them to travel to Spain as well as other Spanish-speaking countries. In 2012, The Buchan Excellence Fund supported the UNC-CH Department of Romance Languages and Literature’s project 21st Century Pen Pals, a video exchange program between American and Spanish schoolchildren.
In December 2016, Buchan House, the new Arts and Sciences Foundation building at UNC-CH, opened after Buchan donated the money to purchase and renovate the old Chapel HillPublic Library to serve as the foundation’s new headquarters. Buchan is Vice-Chair of the UNC-CH Arts and Sciences Foundation Board of Trustees, a member of the Chancellor's Philanthropic Council, and served on the University’s Campaign Planning Cabinet. He has also supported Harvard Business School fundraising.

On the day of his inauguration, the Buchans went to church with Trump and his family, and sat near Trump as he was sworn-in as president.
