BNY Mellon has launched a tokenized deposit service that allows institutional clients to use fiat deposits on-chain for payments, collateral, and margin transactions. The bank, which says it manages $58 trillion in assets as the world’s largest custodial bank, is bringing deposit balances onto a private permissioned blockchain for approved organizations.
The product turns a traditional bank deposit into a digital representation on-chain. The underlying claim remains a real deposit held at the bank, and the tokenized balance is designed to match that value exactly. BNY Mellon said its setup keeps transactions and balances aligned with its regulated banking environment, so the on-chain layer works alongside existing banking infrastructure rather than outside it.
How the tokenized deposit model works
Tokenization in this case means converting a bank-held monetary claim into a blockchain-based token. BNY Mellon’s service is not described as a separate crypto asset. It is a digital version of a deposit balance, backed by funds held within the bank. Access is restricted to approved institutional participants on a private network, with the source naming Citadel, Ripple Prime, and ICE among the organizations that can use it.
The service is built around several practical use cases. It supports 24/7 liquidity management, giving institutions a way to operate outside standard banking hours. It is also intended to speed up transfers for payments and collateral workflows. Because the network is permissioned, participation remains controlled, while transaction records and balances continue to sync with BNY Mellon’s regulated systems.
Part of a broader bank-led shift
BNY Mellon is entering a field that large financial institutions have already started to build out. The source points to JPMD, also known as JPM Coin, which supports round-the-clock payments and collateral management on a private blockchain and expanded to the Canton Network in 2026 for privacy-focused institutional transfers. It also references tokenized deposits in HKD, USD, GBP, and EUR, with pilot activity underway in the UK, Hong Kong, and Singapore.
The article also notes that UK Finance and the Hong Kong Monetary Authority are running 2026 pilot programs for programmable deposits in GBP and HKD. Those tests focus on real-time payments, fraud reduction, and liquidity efficiency. Taken together, these projects show that banks are pushing blockchain infrastructure into areas long dominated by internal ledgers and conventional settlement rails.
Why banks are focusing on programmable deposits
According to the source, the period from 2025 to 2026 has brought a wider change in how global finance approaches on-chain money. Laws including the US GENIUS Act are described as creating a safer environment for bank adoption. The operational case is straightforward: blockchain can reduce settlement times, improve liquidity management, and automate parts of transaction processing.
Programmability is a central feature. Banks can issue deposits that are used only under preset conditions, such as automatic margin calls or payment triggers. For institutions, that means a tool aimed at settlement speed and treasury efficiency. For regulators, the money remains inside supervised banking structures. In the source’s framing, tokenized deposits also give banks a regulated alternative to crypto stablecoins for institutional use.
BNY Mellon’s launch centers on one clear idea: extending trusted bank deposits onto digital rails. The race around tokenized deposits is moving beyond pilots and into live bank infrastructure.
