NEW YORK — Donald Trump has narrowed his focus for Treasury secretary to a pair of candidates, former Goldman Sachs banker Steve Mnuchin and billionaire investor Wilbur Ross, people familiar with the matter said.

Mnuchin, who served as a senior adviser and finance chair for the Trump campaign, is the leading candidate, these people said. The people added that they did not believe Trump had finalized a decision on Treasury and that names in play could still change.

People working on the Trump transition team have also reached out to other potential Treasury secretaries including current JPMorgan Chase CEO Jamie Dimon and Kevin Warsh, a former Federal Reserve governor currently at Stanford’s Hoover Institution, people familiar with the matter said. House Financial Services Chairman Jeb Hensarling (R-Texas) has also been mentioned for Treasury. But Hensarling has said he’s focused on rewriting financial regulations under a Trump presidency.

Dimon has said in the past that he is not interested in the job. He made it clear to Trump transition officials that he would not be a good fit for the job but would be available to offer help and advice to the new administration, a person familiar with the matter said. Warsh is likely to be more focused on future openings at the Federal Reserve.

A Trump spokesperson did not immediately respond to a request for comment on the Treasury search. Mnuchin and Ross also did not immediately respond to requests for comment. Mnuchin, a consistent front-runner for the Treasury job, was seen at Trump Tower in Manhattan on Monday.

Treasury secretary will be a critical post in Trump’s administration helping design a fiscal policy that calls for heavy new spending on infrastructure and a re-rewrite of both the corporate and individual tax code. Much of the work on these plans will be done out of the West Wing of the White House along with House Speaker Paul Ryan and Senate Majority Leader Mitch McConnell. But Treasury will play a key role in both helping craft and eventually selling the plan to Congress and the public.

Mnuchin, 53, spent nearly two decades at Goldman Sachs, where he was a partner and eventually chief information officer. Mnuchin later launched a successful career as a film mogul, backing major films including “Suicide Squad,” which came out over the summer. He is now chief executive of the New York-based hedge fund Dune Capital. Mnuchin received heavy criticism from the left for his role in the takeover of the subprime mortgage business of failed lender IndyMac, which was renamed OneWest and came under fire from regulators for its foreclosure practices.

Mnuchin has said the 2010 Dodd-Frank law, which stepped up regulation of the finance industry, "needs to be looked at." He has also said there are good and bad aspects of the law, according to a Bloomberg profile from August.
