Bank of America, which has come under scrutiny for its treatment of junior bankers, is changing who is overseeing the workloads of its young executives. The bank is now having senior bankers—those who hold a title of director or above—monitor the nature and volume of assignments piled on lower level staff who, in an industry famous for grueling hours, often work well into the night to complete deals. 

Bank of America’s efforts come after a series of tragedies involving young people that have shaken the investment banking sector. In January, Carter Anthony McIntosh, a 28-year-old investment banking associate at Jefferies, passed away from a suspected drug overdose. McIntoch was working as much as 100 hours a week, the New York Post reported. Leo Lukenas, a BofA junior banker, died in May from a blood clot. Lukenas had worked 100-plus hour weeks before his passing. BofA in 2014 instituted policies to limit young banker hours, the junior execs were often pressured into lying about their workloads, the WSJ has reported.

To carry out its oversight program, BofA has long relied on what it calls a chief resource officer model. Under this model, BofA used mid-level executives, on one-year rotations, to allocate work to junior investment bankers, according to the Wall Street Journal. 

BofA has opted to shake up the model as it seeks to build the next generation of leaders, a person familiar with the situation said. The investment bank will now rely on senior bankers, working in permanent, full-time positions across sectors and regions, who will supervise young banker development as their CROs. 

Bank of America  is picking volunteers or assigning the role to the senior bankers, who are no longer dealmakers, the person said. BofA is seeking executives who have a very strong leadership quality, have managed teams and feel strongly about the evolution of junior bankers, they said.

“We want all of our junior bankers to have the best experience possible, learning from the teammates they work with and further benefiting from the career growth and development this role brings,” according to a BofA statement.  

BofA Securities, the investment banking division of Bank of America, employs thousands of bankers. It’s unclear how many are junior bankers. Young executives typically spend several years as a junior banker, including two as an analyst and two to three years as an associate, before they move up to vice president. At that point they usually work on a sector team, like consumer or technology or industrials.

BofA also cut roughly 150 junior investment banking roles, the person. The majority of people that were reduced were “mapped to new roles” outside of investment banking like financial analysis or strategic planning, the person said. “They were given the opportunity to move somewhere else,” they said.
