Shareholders at JPMorgan Chase voted to let Jamie Dimon, the chairman and chief executive, keep both his jobs.
At the bank's annual meeting, just 32 per cent of shareholders voted for a non-binding measure that would have advised the bank to split the roles. That's less than the 40 per cent vote that a similar proposal received last year.
Shareholder groups lobbying for the split gained momentum from a surprise US$6 billion ($7.3 billion) trading loss last year, which tarnished the reputation of both JPMorgan Chase and Dimon.
The bank and Dimon had argued that letting Dimon keep both jobs was the most effective form of leadership.
Dimon emerged from the financial crisis heading one of the strongest banks in the US. But his reputation has been hurt over the past year over fallout from the so-called "London whale" trading loss, nicknamed for its size and the location of the trader who made the outsized bets on complex debt securities that went wrong.
