Tim Tung

Title: Director and Lead Analyst

Firm: S&P Global Ratings

Age: 37

As a director and lead analyst for S&P Global Ratings, Tim Tung is a regular commentator on S&P Global’s podcasts. He is frequently asked to speak at industry conferences, and is viewed as a utility sector expert on topics ranging from the financial implications of drought to climate change and public health.

Born in Baton Rouge, La., Tim grew up in the Los Angeles area. He earned a bachelor’s degree from the University of California at Berkeley and a Masters of public administration at San Jose State University.

Working for the city of San Jose after college, Tim came to know David Persselin, whom he considers the most influential person for his public finance career.

“He was very generous with his time educating the staff on the technical aspects of the industry,” Tim said. “He also encouraged me to pursue my master’s degree while working full time, and the additional formal education has served me well. After we both moved on to other jobs, we continued to keep in contact and co-taught the Financial Administration course for San Jose State University’s MPA Program for several years.”

At S&P, Tim focuses on issuers in the western U.S.; primarily water and sewer utilities, including the City of Los Angeles’ Wastewater System, Los Angeles Department of Water and Power’s Water System, San Francisco Public Utilities Commission’s Water System and Wastewater System, and several other major utilities.

“I see continued growth in the sector as our country continues to develop and increase in population, while existing infrastructure ages and reaches the end of its useful life,” he said.

Recently married, Tim is a marathon runner, a former martial arts practitioner of over 20 years, and an enthusiast photographer.


“Tim is the new face of S&P Global Ratings. He serves as an exemplary role model and thought leader within the U.S. public finance department.” James Breeding, Senior Director, S&P Global Ratings
