Briefing
The Office of the Comptroller of the Currency (OCC) issued Interpretive Letter 1186, explicitly authorizing national banks and federal savings associations to hold native blockchain tokens on their balance sheets for essential operational functions. This action fundamentally alters the risk calculus for institutional participation by providing regulatory certainty on a critical infrastructure component, allowing banks to hold assets like Ether or Solana specifically for paying network fees or testing blockchain-based platforms. This clarity directly enables the compliant build-out of digital asset services, removing the previous operational gap where banks had service authority but lacked explicit permission to hold the required native tokens for underlying network operations.
Context
Prior to this guidance, a significant legal ambiguity existed regarding a national bank’s ability to hold volatile, non-custodial digital assets on its own balance sheet, even in small amounts necessary for operational needs. While previous OCC guidance had permitted banks to offer digital asset custody and operate as blockchain nodes, the lack of explicit permission to hold the native “gas” or “fee” tokens required to transact on public blockchains created a practical and compliance challenge. This regulatory uncertainty forced institutions to rely on complex, non-bank workarounds or limited their engagement to private, permissioned ledgers, effectively hindering the development of compliant, public-chain-based institutional products.
Analysis
This Interpretive Letter mandates an immediate update to internal compliance frameworks, specifically in the areas of balance sheet risk and technology governance. Regulated entities must now integrate controls for managing the operational holding of native tokens, focusing on robust liquidity, cybersecurity, and illicit finance screening protocols. The permission is narrowly tailored, requiring banks to demonstrate institutional-grade controls that strictly limit exposure to volatile assets while enabling necessary on-chain activities. This systemic update to the operational OS allows banks to move beyond theoretical service offerings to the practical, compliant deployment of custody, settlement, and tokenization products.
Parameters
- Agency Instrument ∞ Interpretive Letter 1186, which provides formal legal clarity on the scope of permissible bank activities.
- Permitted Use Case ∞ Holding native tokens for network fees or platform testing, which is the necessary “gas” for blockchain operations.
- Targeted Entities ∞ National banks and federal savings associations, which are core US financial market participants.
Outlook
The OCC’s action sets a clear precedent for how US regulators will address the operational realities of public blockchain technology, signaling a shift toward enabling, rather than strictly prohibiting, institutional engagement. This clarity is expected to accelerate the development of tokenized assets and blockchain-based settlement systems within the US banking sector. The next phase will involve other federal regulators, such as the Federal Reserve and the FDIC, aligning their supervisory expectations, potentially leading to a harmonized framework that solidifies the compliant bridge between traditional finance and decentralized infrastructure.
