Secura/Isaac Group will bring its regulatory expertise to StoneCastle’s insured deposit solutions, offering new advisory and consulting services to help clients navigate strategy, regulation and technology
NEW YORK (September TK, 2025) – Secura/Isaac Group today announced its collaboration with StoneCastle, making the global advisory firm a StoneCastle company. The partnership will provide senior-level regulatory expertise to StoneCastle’s insured depository institution clients.
As the banking regulation landscape develops and becomes increasingly complicated, it is crucial for banks and other depository institutions to understand how regulation applies to them before they land themselves in hot water. This is especially true with the rapid expansion of the fintech industry, which has produced countless new solutions to depository institutions and their customers.
Secura/Isaac Group (SIG), a global advisory firm led by former FDIC and Fifth Third Bancorp Chairman William Isaac, excels at guiding clients through today’s complex regulatory environment and implementing important industry initiatives. The team of highly experienced former bankers, regulators and finance executives helps clients address the unprecedented challenges posed by rapid technological advances, growing cybercrime activity and a shifting regulatory landscape.
Since 2009, StoneCastle has offered superior deposit solutions, providing up to $100 million in federal insurance protection per client tax ID. Its services are used by a wide range of depositors, including wealth managers, Fortune 500 corporations, endowments, municipalities, family offices and others. StoneCastle’s federally insured cash account delivers the best combination of absolute safety, rate, liquidity and convenience.
StoneCastle also makes capital investments to provide liquidity and strategic guidance to depository institutions. StoneCastle’s network of over 1,000 banks is one of the largest in the country. This new partnership will add the expertise of Secura/Isaac Group’s former regulators to help support StoneCastle’s network of depository institutions and depositors with deep knowledge of current regulations and longstanding relationships with regulators.
With recent years being notably turbulent for the banking industry, it is more important than ever for depository institutions to be poised to deal with crises. By combining StoneCastle’s solutions with Secura/Isaac Group’s banking and regulatory experience, banks and institutional depositors can be extremely prepared. The team is poised to use its expertise to get institutions out of regulatory trouble, but an even better approach would be to avoid trouble altogether by having experienced advisors in your corner from day one.
“When we first met with StoneCastle, we quickly realized that we shared the same values, including how much we care about community and regional banks,” said Bill Isaac, Chairman of Secura/Isaac Group. “StoneCastle provides exceptional value to both depositors and depository institutions. Becoming a StoneCastle company will help Secura/Isaac Group reach more depository institutions and guide them through regulations and emerging policies before they find themselves in a sticky situation.”
“We are excited to provide our network with Secura/Isaac Group’s unparalleled regulatory expertise,” said Joshua Siegel, Founder and CEO of StoneCastle. “We want our clients to understand the regulatory playbook before rolling out new strategies and solutions, rather than launching a product today and having to work backwards to meet regulatory expectations tomorrow.”
