NEW YORK, Nov 6 (Reuters) - JPMorgan Chase ( JPM ) CEO

Jamie Dimon will remain at the bank and has no plans to join

Donald Trump's administration despite questions about whether he

would take a senior government role after the U.S. presidential

election, a source said.

Dimon, 68, has been the subject of repeated speculation in

recent weeks as a candidate for Treasury secretary by both

Republicans and Democrats, but he said last month that his

chances of taking an official post were "almost nil". Reuters

was the first to report his intentions to stay at the helm.

The executive, who is one of the most prominent leaders in

corporate America, has run JPMorgan ( JPM ) for almost 19 years. The

bank's board has named four candidates to succeed Dimon when he

eventually steps down.

"Our country is now concluding one of the hardest fought and

at times divisive elections in our recent history," Dimon said

in a statement on Tuesday before the election results emerged.

"Soon it will be time for all of us to unite behind our

President elect and all of our national leaders."

While the veteran banker continued his tradition of not

endorsing any presidential candidate this year, he frequently

weighed in on economic and financial policies, as well as

geopolitical and national challenges.

Meanwhile, media reports said his wife Judy Dimon traveled to

Michigan last weekend to campaign for Kamala Harris, Trump's

Democratic opponent.

Dimon had previously downplayed the chances of taking a

government position, telling analysts in October that "I

probably am not going to do it... but I always reserve the

right" to reconsider.

JPMorgan's ( JPM ) stock jumped over 11% on Wednesday alongside a

similar gain for a broader S&P 500 index of bank stocks as

investors speculated the incoming administration would be more

friendly to lenders.

Taylor Krystkowiak, an investment strategist at asset

manager Themes ETFs in Washington, said investors would welcome

the CEO remaining in place.

"Dimon has continued to guide JPMorgan ( JPM ) effectively

throughout his long tenure at the bank's helm, and his decision

to remain there is unsurprising," Krystkowiak said.

"Given that the bank has delivered robust results under his

leadership, markets will likely laud Dimon's decision to stay,

renewing fresh confidence in the stock's prospects."

Dimon is credited with steering the bank through the 2008

financial crisis and last year's regional bank turmoil. During

his tenure, JPMorgan ( JPM ) became the largest bank in the U.S., far

surpassing its rivals.

"He has built the bank into a formidable company and has the

best job in the world, and he will likely stay where he is," Tim

Adams, CEO of the Institute of International Finance, a banking

industry group, told Reuters before the election.

Speculation around Dimon's plans intensified this year after he

announced that his timeline for stepping down is no longer five

years and could be as soon as two-and-a-half years.

The outspoken CEO travels frequently to Washington to speak with

policymakers and has expressed views on everything from housing

and the U.S.-China relationship to the economy. He vowed to

"fight back" and sue regulators for rules that he viewed as

ineffective in a profanity-laced address to an industry

conference last week.

"I've always been an American patriot and my country is more

important to me than my company," Dimon told analysts on a call

last month when asked about his plans.
