Even if a bank or trust company fails, trust assets are safe. By law, trust assets must be kept separate from all other assets. They cannot be loaned out, mixed with the corporate trustee’s own assets or used to satisfy its creditors. Because of these safeguards, trust assets are not insured by the FDIC.
You are also protected against fraud, theft (for example, if an employee takes trust assets and disappears), or if they make an error administering your trust. But, of course, there is no insurance or bond that will protect you if your assets lose value simply due to a decline in market values.
