Another former top executive of J.P. Morgan Chase & Co. is getting a corner office of his own.

British bank Standard Chartered PLC on Thursday named Bill Winters its next chief executive officer, making him the latest former deputy to J.P. Morgan CEO James Dimon to land the top job at a major financial firm. Other former J.P. Morgan executives now run credit-card company Visa Inc.; payments processor First Data Corp.; and PNC Financial Services Group Inc., one of the nation's largest regional banks.

For Mr. Dimon, leader of the largest U.S. bank by assets, his firm's emergence as a top breeding ground is both a blessing and a curse, highlighting his firm's ability to develop talent as well as the uncertainty surrounding J.P. Morgan's succession plan.

J.P. Morgan hasn't named a successor to Mr. Dimon, who turns 59 next month and was diagnosed with throat cancer last summer. After going through a course of treatment, Mr. Dimon told bank employees in December that tests showed no evidence of cancer in his body.

J.P. Morgan isn't the first company that has seen its executives rise to the top of the firm only to jump ship.

"If Jamie is going to aspire to be the best global bank in the universe, he's going to lose good people, and he has lost good people," said former McKinsey & Co. head Ron Daniel, who ran the consulting firm from 1976 to 1988 and has spoken with Mr. Dimon about top executives inevitably leaving leading firms.

Mr. Daniel said other companies that have wrestled with this in past years include Procter & Gamble Co., International Business Machines Corp. and General Electric Co.

GE perhaps provides the best corollary. The conglomerate was led by Jack Welch for two decades, and he became closely identified with the company's image, just as Mr. Dimon has at J.P. Morgan.

The planning for Mr. Welch's exit began with a list of 23 internal candidates seven years before he left, eventually pitting Jeffrey Immelt against fellow executives Robert Nardelli and Jim McNerney.

The process, lauded by many outsiders, proved internally divisive. Messrs. Nardelli and McNerney each announced they were leaving to take CEO positions at other companies within 10 days of being informed by Mr. Welch, at the end of a Thanksgiving weekend, that Mr. Immelt was getting the top job.

At J.P. Morgan, Mr. Winters was out of the running to succeed Mr. Dimon long ago.

Mr. Winters, who was based in London, wasn't a close ally of Mr. Dimon, and Mr. Dimon wasn't a guiding force in his career. Mr. Winters rose through the ranks of J.P. Morgan predecessors over 26 years and was a senior executive there when Mr. Dimon joined the bank in 2004.

Mr. Winters earned $20.2 million at J.P. Morgan in 2007, making him the second-highest paid executive at the bank, according to a financial filing.

Ultimately, Mr. Dimon ousted Mr. Winters from the bank in 2009 after the pair repeatedly clashed and Mr. Winters had a falling out with another senior executive, according to people familiar with the matter. Mr. Winters had chafed under Mr. Dimon's leadership, frustrated by what he regarded as the bank's overly risky investment strategies and what he believed was Mr. Dimon's imperialistic management style, according to people familiar with their relationship.

Furthermore, Mr. Winters had hoped to succeed Mr. Dimon in the CEO post, but Mr. Dimon, in his early 50s at the time, and the board weren't willing to tap him for the job, these people said.

After leaving J.P. Morgan, Mr. Winters was considered for a number of bank CEO jobs, according to people familiar with the matter, but instead set up an asset-management firm to buy assets that were expected to be sold by downsizing banks.

The two rarely have spoken since Mr. Winters left J.P. Morgan, but Mr. Dimon called Mr. Winters on Thursday to congratulate him on the new job, according to people familiar with the conversation.

"I enjoyed working with Bill for years, and I have high respect for him, " Mr. Dimon said in an interview Thursday. "It's a great choice for the role at Standard Chartered, and he'll do a really good job."

Other high-level departures from J.P. Morgan in recent years include longtime executives who were part of Mr. Dimon's inner circle dating back to their early careers at the predecessor of Citigroup Inc. in the 1980s.

Among them are Charles Scharf, who oversaw J.P. Morgan's retail-banking business and now runs Visa and counts J.P. Morgan among its biggest customers; Frank Bisignano, who ran J.P. Morgan's operations, is the CEO of First Data; and former J.P. Morgan Chief Financial Officer Michael Cavanagh, once viewed as a potential successor to Mr. Dimon, who left the bank last year to join Carlyle Group LP as co-president and co-chief operating officer.

"This speaks to the quality of the management team that J.P. Morgan had at one time and still has," said Steve Black, a Wall Street veteran who ran J.P. Morgan's investment bank with Mr. Winters. He is now co-CEO of Bregal Investments, the private-equity arm of a European holding company.

J.P. Morgan has said its executives work closely with the board on succession planning. Among those considered candidates to succeed Mr. Dimon are retail head Gordon Smith and asset-management chief Mary Callahan Erdoes, people familiar with the succession planning have said. Other candidates include Chief Operating Officer Matt Zames; Doug Petno, chief of the commercial bank; Daniel Pinto, chief of the corporate and investment bank; and Marianne Lake, chief financial officer, these people said.

Citigroup was regarded for many years as one of Wall Street's top training grounds for financial executives. The mantle then passed to Goldman Sachs Group Inc., which saw a number of senior executives leave to run companies, including Duncan Niederauer to the New York Stock Exchange and John Thain to lender CIT Group Inc. Mr. Thain also was CEO of Merrill Lynch and the NYSE.
