In October 2023, JPMorgan’s blockchain-based platform Onyx processed $1 billion in tokenised transactions in a single day. BlackRock launched its first tokenised fund on Ethereum in March 2024. Citi piloted tokenised deposits for institutional clients across multiple jurisdictions. These are not crypto startups. They are the largest financial institutions in the world deploying blockchain technology for core financial functions. The global blockchain technology market reached $31.18 billion in 2025, according to Fortune Business Insights, and is projected to grow to $577.36 billion by 2034 at a 36.50% compound annual growth rate. Financial services accounts for 23.52% of that market, the largest industry segment.
Where Blockchain Is Already Deployed in Finance
Blockchain adoption in financial services is concentrated in four areas where the technology solves specific, measurable problems that traditional infrastructure cannot.
Cross-border payments is the most advanced use case. Traditional correspondent banking routes international transfers through chains of intermediary banks, each adding fees and processing time. Blockchain-based payment networks compress this to a single transaction between sender and receiver, settling in minutes rather than days. Blockchain-enabled gateways now account for 27% of cross-border payment volume, according to Coinlaw’s blockchain financial services data, with total blockchain-based cross-border payments estimated at $3 trillion in 2025, growing at 45% annually. Ripple’s payment network connects over 300 financial institutions across 40 countries for real-time cross-border settlement.
Securities settlement is the second major use case. Traditional securities trades settle in T+1 (one business day after the trade) in the US, and T+2 in many other markets. The settlement process involves multiple intermediaries: brokers, clearinghouses, custodians, and central securities depositories. Blockchain enables atomic settlement, where the security and the payment transfer simultaneously in a single transaction, eliminating counterparty risk and reducing the capital that must be held against unsettled trades.
Trade finance is the third area. A letter of credit for an international shipment traditionally involves paper documents, physical signatures, and a review process that takes 5 to 10 business days. Blockchain-based trade finance platforms (Contour, Marco Polo, we.trade) digitise the document flow, creating a shared ledger where all parties (exporter, importer, banks, shipping company, insurer) can view and verify documents in real time. Processing times drop from days to hours.
Digital identity and KYC (know your customer) is the fourth. Financial institutions spend billions annually on customer identity verification and ongoing monitoring. Blockchain-based identity solutions allow a customer to verify their identity once and share the verified credentials with multiple institutions, eliminating duplicate verification processes across banks and financial service providers.
Tokenisation: The Largest Opportunity
Tokenisation, representing real-world assets as digital tokens on a blockchain, is the financial application with the largest potential impact. A tokenised asset (a bond, a share of a fund, a piece of real estate) can be traded 24/7, settled instantly, fractionated into small units, and transferred globally without the intermediaries that traditional asset transfer requires.
BlackRock’s BUIDL fund, launched on Ethereum in March 2024, attracted over $500 million in assets within months, making it the largest tokenised fund at the time. Franklin Templeton’s tokenised money market fund exceeded $700 million. These are not experiments. They are production deployments by the world’s largest asset managers.
Tokenised deposits are a related application. JPMorgan’s Onyx, Citi Token Services, and HSBC’s Orion allow institutional clients to represent bank deposits as digital tokens that can settle securities transactions instantly, facilitate programmable payments, and operate across time zones without the limitations of traditional payment processing hours.
North America dominates blockchain technology adoption with 43.80% of the global market in 2025, per Fortune Business Insights. The US alone is projected to reach $14.26 billion in blockchain market value by 2026. That concentration reflects both the depth of US capital markets (where tokenisation benefits are largest) and the regulatory framework that, despite its complexity, has allowed financial institutions to deploy blockchain under existing securities and banking law.
Decentralised Finance and Its Intersection With Traditional Banking
Decentralised finance (DeFi) operates parallel to traditional financial services, using blockchain-based smart contracts to provide lending, borrowing, trading, and insurance without traditional intermediaries. DeFi protocols on Ethereum, Solana, and other blockchains process billions of dollars in daily transaction volume.
The intersection of DeFi and traditional finance is growing. Aave, one of the largest DeFi lending protocols, launched Aave Arc for institutional users, incorporating KYC requirements and compliance controls that allow regulated institutions to participate. MakerDAO, which issues the DAI stablecoin, holds US Treasury bonds as collateral, connecting decentralised protocols directly to traditional government debt markets.
For traditional banks, DeFi represents both competition and opportunity. Competition because DeFi protocols offer lending, borrowing, and trading at lower cost and higher speed than traditional banking infrastructure. Opportunity because banks can use DeFi protocols as infrastructure for their own products, accessing liquidity pools, automated market making, and programmable financial logic that would be expensive to build internally.
Regulatory Frameworks Taking Shape
Financial regulators worldwide are building frameworks specifically for blockchain-based financial services. The EU’s Markets in Crypto-Assets regulation (MiCA), which took full effect in December 2024, provides a comprehensive licensing framework for crypto asset service providers, stablecoin issuers, and token offerings across all 27 member states.
The EU’s DLT Pilot Regime, operational since March 2023, allows regulated financial institutions to experiment with blockchain-based securities trading and settlement under a controlled regulatory environment. This pilot has allowed European banks and exchanges to test tokenised securities without waiting for permanent legislation.
In the US, the regulatory picture is more fragmented. The SEC, CFTC, OCC, and state regulators each claim jurisdiction over different aspects of blockchain-based finance. Despite this complexity, major US banks have deployed blockchain technology under existing regulatory frameworks. JPMorgan, Citi, and Goldman Sachs operate blockchain platforms that comply with current banking and securities law.
Europe accounts for 28.30% of the global blockchain market, per Fortune Business Insights, with Germany ($2.52 billion by 2026) and the UK ($2.08 billion) as the largest national markets. The regulatory clarity provided by MiCA is expected to accelerate European adoption relative to the US, where regulatory uncertainty has slowed some institutional deployments.
What Has Not Changed
Blockchain has not replaced traditional financial infrastructure. It has added a new layer. The vast majority of financial transactions still flow through conventional systems: SWIFT for interbank messaging, card networks for consumer payments, clearinghouses for securities settlement. Blockchain is processing a growing share of specific transaction types (cross-border payments, securities settlement, trade finance) where its advantages in speed, cost, and transparency are clearest.
Eighty-three percent of financial institutions globally are now exploring or deploying blockchain solutions, per Coinlaw. But “exploring” and “deploying at scale” are different stages. Most institutional blockchain projects remain in pilot or limited production. The full transformation of financial infrastructure will take years, constrained by regulatory approval, technology integration with legacy systems, and the organisational change required to adopt fundamentally new processes.
Blockchain technology is transforming financial services at the infrastructure level, not the consumer-facing level. The customer sending an international transfer may never know that blockchain settled the transaction. The investor buying a tokenised bond may not care what technology backs it. The transformation is real, but it is happening in the plumbing of finance, not in the products that customers see.
