Capital markets platform Clear Street said on Wednesday that broker-dealer regulatory lawyer Julian Rainero has joined the firm in New York as Chief Regulatory Counsel.
He will lead regulatory strategy and advise on broker-dealer regulation, market structure, and customer asset protection as the firm expands its clearing and prime brokerage infrastructure.
Rainero joined from McDermott Will & Schulte, where he chaired the broker-dealer practice group. Over a 30-year career, he has represented clearing firms, prime brokers, electronic market makers, and alternative trading systems, Clear Street said.
His expertise in net capital rules, customer asset protection, securities finance, margin, and securities lending relates to the platform’s operations across execution, clearing, custody, and financing.
“Regulation and market structure sit at the center of Clear Street’s products and services, and I’m energized by the chance to help shape how a platform of this scale operates within a variety of markets,” Rainero said.
The hire comes as FINRA’s 2026 oversight priorities continue to target broker-dealer compliance, net capital, and customer asset protection.
Clear Street was founded in 2018 and has raised $1 billion. The firm says it serves more than 700 institutional clients with roughly $16 billion in customer balances.
