What Chain Bridge Bancorp, Inc. told the SEC could break it.
Chain Bridge Bancorp's disclosures describe concentration on nearly every axis. Its lending is tied to one market — about 83.4% of loans (73.2% residential real estate) are to borrowers in the Washington, D.C. metro area — and its branch-less model limits expansion beyond it. Its funding is unusually exposed too, with roughly $1.2 billion, or about 75% of total deposits, uninsured by the FDIC and therefore more prone to rapid withdrawal if the bank is perceived to be in distress. It also depends on key third parties — IntraFi's ICS network for deposit placement and liquidity, and a single core technology provider for its banking software — where losing either would cause withdrawals, lost revenue or operational disruption.

About $1.2B (75%) of Chain Bridge's deposits were uninsured at year-end 2025; such uninsured deposits are more likely to be withdrawn quickly if the bank is perceived to be in distress, creating concentrated deposit-run/liquidity risk.
“As of December 31, 2025, we estimate that approximately $1.2 billion, or approximately 75.0% of our total deposits, were not insured by the FDIC. These uninsured deposits may be more likely to be withdrawn if we experience, or are perceived to experience, financia”

Supplier concentration

“we rely on a core technology provider for the banking software used by our clients and operations personnel.”
