Block, IncBlock filed for an OCC national trust bank charter to custody Bitcoin and stablecoins, seeking federal preemption of state money transmitter licensing.

Block, Inc. filed an application with the Office of the Comptroller of the Currency on September 8, 2026 for a national trust bank charter under the name Builders Bank & Trust, N.A., seeking federal authorization to custody Bitcoin and stablecoins at institutional scale. The charter is uninsured and non-deposit-taking, meaning Block is not seeking to become a traditional bank, but rather to bypass the state-by-state money transmitter licensing regime that has constrained its Cash App business since inception. Block's filing joins a broader charter wave that has sorted into three distinct lanes: crypto-native firms such as Circle, which received final OCC approval in July, Ripple, which obtained a conditional charter, and BitGo, which secured final approval; Wall Street institutions including JPMorgan, BNY Mellon, and State Street, which have expanded digital asset custody through existing banking licenses rather than new charters; and Block itself, a consumer fintech with over 50 million monthly active users on Cash App that is building institutional plumbing. The structural advantage of an OCC trust charter is preemption, replacing a patchwork of state requirements with a single federal framework and providing access to the Federal Reserve's payment rails and correspondent banking network. The timing matters, as the CLARITY Act heads for a Senate floor vote on September 15 and the GENIUS Act, signed into law in July, established a stablecoin-specific regulatory framework, while the OCC's processing timeline for national trust bank charters has varied from six months to over a year.
