The change of chairs hasn't yet been officially announced at the agency, though the remaining commissioners — including Hester Peirce and Caroline Crenshaw — issued a joint statement on former Chair Gary Gensler's exit.
"Although as Commissioners we approached policy issues from different perspectives, there was always dignity in our differences," the commissioners said. "Chair Gensler has been committed to bipartisan engagement and a respectful exchange of ideas, which has helped facilitate our service to the American public."
Gensler had previously announced he would resign at noon on Jan. 20 — the same time Trump was sworn into office.
Gensler had become the chief government antagonist for the crypto industry in recent years. He pursued enforcement cases, pushed controversial crypto accounting policy, favored tough rule proposals that threatened the industry's business model and blocked — for a time — the establishment of spot crypto exchange traded funds (ETFs). On the latter point, a court ruling against the agency forced Gensler's hand, and he eventually voted with the commission's Republicans to clear the path for ETFs.
His agency argued in court that existing law was sufficient to categorize and regulate crypto assets. That stance was favored by some federal judges and opposed by others, and the central questions are still working its way through the courts.
Uyeda's SEC, for however long his tenure lasts, is absent virtually all senior legal officials that worked under Gensler, including in the enforcement division and the general counsel's office.
The acting chairman has the full authority of the office, but people in that position sometimes choose to defer to the incoming chair and wait on big decisions.
At the SEC's sister agency, the Commodity Futures Trading Commission, Republican Commissioner Caroline Pham has been lifted to the acting chair role there, though Trump hasn't yet named a permanent successor to the outgoing Democrat chair, Rostin Behnam.
Unlike the CFTC, which currently has a 2-2 split between the parties, the SEC's Republicans outnumber the lone Democrat 2-1.
