Block’s Builders Bank Plan Is for Crypto Custody, Not Deposits or Loans

Block is not asking Washington to turn Cash App into an FDIC-insured lender. Its Builders Bank application is for a narrower institution: an uninsured national trust bank that would custody digital assets, execute client trades and move stablecoins, while taking neither deposits nor making loans.

That distinction is the useful answer for investors following Block’s September 8 announcement. A federal charter could simplify supervision of crypto-custody activities and open an institutional service line, but it would not transform the company’s funding model or give it a conventional bank balance sheet. Approval also remains pending.

Block shares ended Friday at $79.21, about 1.1% below their September 8 close, according to daily market data. That muted reaction is consistent with an option on future revenue rather than an immediate earnings event.

What Builders Bank would be allowed to do

The public charter application, dated September 4, describes Builders Bank & Trust, N.A. as a wholly owned Block subsidiary based in Sioux Falls, South Dakota. It would operate nationally over a three-year de novo period and provide four principal services:

• fiduciary custody and safekeeping of bitcoin and other digital assets;
• customer buy and sell orders executed on a riskless-principal basis;
• customer-directed deposits, withdrawals and transfers of digital assets; and
• stablecoin settlement and transfer services.
