Rain applies to OCC for a national trust bank built around stablecoins

Rain wants a federal bank charter. On October 5, 2026, the enterprise infrastructure provider, which focuses on stablecoin payments, filed an application with the Office of the Comptroller of the Currency (OCC) to create Rain National Trust Bank, or RNTB.

The proposed bank would be based in New York. The timing is the interesting part: the filing landed three days after the ICBA sued the OCC over the very rules that make charters like this possible.

What Rain is actually asking for

If the OCC signs off, RNTB would operate as a national trust bank. The planned business has three main pieces.

First, fiduciary custody of digital assets and US dollars. Second, reserve management for stablecoin issuers. Third, the issuance and redemption of US dollar-backed stablecoins for institutional clients.

What RNTB would not do matters just as much. It would not take customer deposits, open consumer accounts, or make commercial loans.

Client assets would also be kept separate from the bank’s own assets. There is no FDIC insurance in this setup either. The pitch to institutions is federal supervision, not a government backstop on balances.

Rain has also picked its proposed leadership. Brandon Soto, formerly chief financial officer of Square Financial Services, is slated to serve as RNTB’s president and CEO.

A crowded line at the OCC

Rain is not knocking on an empty door. The OCC has approved or conditionally approved at least 21 national trust banks, and 13 or more of those are tied to crypto.

The most prominent recent precedent is Circle. The OCC approved Circle National Trust in July 2026, giving a major stablecoin issuer its own federally chartered trust entity.

Then there is the legal cloud. On October 2, 2026, the ICBA filed a lawsuit against the OCC targeting the rules that enable these charters.

What this means

For Rain, a charter would mark a shift in identity. Today it describes itself as infrastructure. With RNTB, it would become a federally supervised custodian and reserve manager.

The reserve management piece may be the most consequential. Stablecoins only work if holders believe each token is backed by what the issuer says it is backed by. A federally chartered trust bank managing those reserves could offer issuers a more credible answer to that question than an unregulated service provider.

The no-deposits, no-loans design also narrows the risk profile. A bank that does not lend out client money has fewer ways to get into the classic kind of trouble.

Rain’s application is pending, and approval is not guaranteed. The OCC may approve, conditionally approve, or reject it, and conditional approvals typically come with requirements to meet before full operation.

The ICBA lawsuit is a significant wildcard. If the challenge gains traction, it could slow or complicate the approval pipeline for Rain and others still waiting.
