Blockchain in Financial Services: Revolutionizing Payments, Lending, Compliance, Custody, and Tokenized Asset Markets

Blockchain in financial services optimizes payments, lending, and compliance by replacing centralized intermediaries with distributed ledgers. According to the Bank for International Settlements (BIS), these systems enable near-instant settlement of assets and reduce operational costs by automating verification through smart contracts.

Financial institutions are currently integrating blockchain to move away from traditional T+2 settlement cycles, where trades take two business days to finalize. By using atomic settlement, assets and payments are exchanged simultaneously, removing the counterparty risk associated with waiting periods, according to reports from the BIS.

How is blockchain changing payment systems?

Blockchain reduces the reliance on the correspondent banking network, which typically requires multiple intermediary banks to move money across borders. This legacy system often results in high fees and delays of several days.

JP Morgan utilizes its Onyx blockchain platform to facilitate instantaneous cross-border payments. The platform uses a proprietary digital currency to settle transactions in real time, bypassing the traditional SWIFT messaging delays for participating clients, according to JP Morgan’s technical documentation.

The adoption of stablecoins—digital assets pegged to a reserve like the U.S. dollar—has further accelerated this shift. The International Monetary Fund (IMF) has noted that stablecoins provide a more efficient medium for exchange in digital markets, though they require strict regulatory oversight to prevent systemic risk.

What is the impact of asset tokenization?

Tokenization is the process of converting ownership rights of a physical or financial asset into a digital token on a blockchain. This allows for fractional ownership, meaning high-value assets like commercial real estate or private equity can be split into smaller, tradable shares.

BlackRock launched the BUIDL fund, a tokenized liquidity fund on the Ethereum blockchain. According to BlackRock, this allows institutional investors to earn yields on U.S. Treasuries while maintaining the ability to transfer ownership of those assets instantly on-chain.

This contrasts with traditional treasury funds, which require manual account updates and brokerage intervention. Tokenized assets move from a manual record-keeping system to a shared ledger, which reduces the need for reconciliation between the buyer’s and seller’s banks.

How does blockchain improve lending and compliance?

In lending, blockchain enables the use of smart contracts—self-executing contracts with the terms written directly into code. These contracts can automatically trigger the release of funds once collateral is verified on-chain, removing the need for a manual loan officer for standardized products.

Compliance and RegTech (regulatory technology) are benefiting from the immutable nature of blockchain. The Financial Action Task Force (FATF) has emphasized the importance of the “Travel Rule,” which requires financial institutions to share sender and receiver information for digital asset transfers.

Institutions are now implementing “Zero-Knowledge Proofs” (ZKPs) to meet these requirements. ZKPs allow a bank to prove a customer is verified (KYC) or meets a specific age or residency requirement without revealing the customer’s actual private data on the public ledger, according to technical standards used by several enterprise blockchain consortia.

What are the current standards for digital custody?

Digital custody involves the secure storage of private keys that grant access to blockchain assets. For institutional players, the risk of a single point of failure—such as a lost password or a hacked hardware wallet—is unacceptable.

Fidelity Digital Assets and BNY Mellon have developed institutional-grade custody solutions using Multi-Party Computation (MPC). MPC splits a private key into multiple fragments distributed across different locations. No single party ever holds the full key, which prevents a single breach from compromising the assets, according to BNY Mellon’s product specifications.

This differs from traditional custody, where a bank holds a physical certificate or a digital entry in a centralized database. In blockchain custody, the bank manages the cryptographic access to the asset itself on the network.

The shift toward these systems is a direct response to the volatility and security breaches seen in early cryptocurrency exchanges. By moving to MPC and hardware security modules (HSMs), banks are applying traditional security rigor to decentralized technology.
