StoneCastle: A Legacy of Protection

For more than 15 years, StoneCastle’s federally insured cash offerings have been an integral part of the cash conversation with registered investment advisors, Fortune 500 companies, family offices, and other institutional investors and has become synonymous with safety.

Our celebrated Federally Insured Cash Account (FICA) has carried the torch by insuring tens of billions of dollars for institutional clients over the years. It was this institutional focus that proved to be the natural bridge into the RIA/advisory space, an endeavor we began in 2017 and one that has grown to service more than 500 advisors with billions of their clients’ cash protected day in and out.

KEEP… protecting your clients’ cash.
