Block says it has submitted an application to US regulators to establish a federally regulated, uninsured national trust bank called Builders Bank & Trust
The financial technology company is seeking to establish a federally regulated, uninsured national trust bank — Block wants to build a bank.
Context & Ripple Effects
Block’s proposed trust bank extends its regulated-finance buildout after expanding Cash App Borrow through Square Financial Services. It also enters a charter path Circle pursued in 2025, culminating in regulatory approval for Circle’s digital-currency trust bank in July 2026.
The application matters because a national trust charter can place custody and related financial infrastructure inside a federally regulated entity, rather than leaving those functions solely within Block’s existing product businesses.
First-order effects
- Builders Bank & Trust becomes a proposed, regulator-reviewed vehicle for Block’s bitcoin and stablecoin custody plans; it cannot operate as a bank unless the application is approved.
- Block gains a defined institutional-finance structure alongside its consumer lending activity, while the proposed bank is explicitly uninsured.
Second-order effects
- Circle’s approved trust-bank operation and Block’s application sharpen competition to provide regulated custody infrastructure for institutional digital-asset clients.
- The application raises the value of a federal trust charter for firms that want to combine digital-asset custody with payments and other regulated financial services.
Third-order effects
- If more fintech and crypto firms pursue this route, national trust banks may become a core layer of digital-asset market structure: regulated custodians connecting consumer platforms, institutional clients, and payment systems.
- The divide between deposit-taking banks and uninsured trust institutions may become more consequential, making charter scope and custody safeguards central competitive variables.
The trend: Digital-asset platforms are moving custody and settlement functions into federally supervised trust-bank structures rather than treating them as standalone crypto services.
