In November 2023, Goldman Sachs issued a €100 million digital bond on a blockchain, settling the transaction in the same day instead of the standard two-day cycle. The bond was denominated in euros, registered under Luxembourg law, and purchased by institutional investors through a familiar process. The only difference was the settlement infrastructure. One transaction, executed by one of the most risk-averse institutions in finance, demonstrated why banks are investing in blockchain: it solves specific, expensive operational problems. The global blockchain market reached $31.18 billion in 2025, according to Fortune Business Insights, and financial institutions account for 23.52% of that spending.
The Cost Problem That Drives Exploration
Financial institutions spend heavily on operations that blockchain can streamline. Post-trade processing, which includes clearing, settlement, custody, and reconciliation, costs the global securities industry an estimated $17 to $24 billion annually, according to multiple industry analyses. Much of this cost stems from the fact that each institution maintains its own record of every transaction, and these records must be reconciled against each other before settlement is considered final.
A single equity trade on the New York Stock Exchange involves at least five separate entities: the buyer’s broker, the seller’s broker, the exchange, the clearinghouse (DTCC), and the depository. Each entity records the trade independently. If any record disagrees with the others, the trade “fails,” requiring manual intervention. The DTCC reported that approximately 2% of US equity trades fail to settle on time, generating operational costs and counterparty risk.
Data from Chainalysis’s 2024 Global Crypto Adoption Index shows that emerging markets in South and Southeast Asia continue to lead grassroots cryptocurrency adoption, driven by remittance use cases and limited access to traditional banking services.
According to CoinGecko’s 2024 annual crypto report, total cryptocurrency market capitalisation exceeded $3.5 trillion by the end of 2024, reflecting renewed institutional interest following spot ETF approvals in the United States.
Blockchain reduces this complexity by giving all parties a single, shared record. When Goldman Sachs settled its digital bond on the same day, both issuer and investor were reading from the same ledger. There was nothing to reconcile. The settlement was final the moment the transaction was confirmed on the blockchain.
JPMorgan’s Onyx platform, which processes over $1 billion in daily repo transactions, reported a 60% reduction in settlement failures compared to its traditional process. That improvement translates directly into lower operational costs, reduced counterparty risk, and freed-up capital that was previously held in reserve against potential failures.
Competitive Pressure From Fintech
Banks are also exploring blockchain because fintech competitors are already using it. Stripe’s $1.1 billion acquisition of Bridge in October 2024 gave the payments company stablecoin settlement infrastructure that processes cross-border payments faster and cheaper than correspondent banking. Blockchain-based cross-border payments now handle approximately $3 trillion per year, growing at 45% annually, according to Coinlaw.
For a global bank that earns revenue from cross-border payment fees, that $3 trillion figure represents market share being captured by alternative infrastructure. A corporate treasurer who can send $500,000 from New York to Singapore in minutes through a stablecoin payment rail has less reason to use a correspondent banking transfer that takes three days and costs significantly more.
Neobanks and digital asset companies are applying additional pressure. Revolut, which has over 40 million customers, integrates cryptocurrency services and is exploring blockchain-based payment routing. Nubank in Brazil, with over 90 million customers, offers cryptocurrency trading. These companies do not carry the infrastructure costs of branch networks and legacy core banking systems, so they can invest a larger share of revenue in new technology.
The result is a competitive dynamic where banks must explore blockchain not because they want to but because the cost of not exploring it is losing customers and revenue to companies that already have. Blockchain is becoming a competitive requirement rather than a strategic choice.
What Banks Are Actually Building
Financial institutions are concentrating their blockchain investment in four areas, each tied to a specific business problem.
Securities settlement is the most active area. The European Investment Bank issued a €100 million digital bond on Ethereum in 2023. The World Bank has issued blockchain-based bonds (bond-i) on a private Ethereum network. HSBC launched its Orion platform for tokenised bond issuance, allowing institutional clients to issue and settle bonds on a blockchain with same-day finality. These are not pilot programmes. They are live capital markets products processing real transactions.
Trade finance is the second focus. Letters of credit, bills of lading, and warehouse receipts have historically required physical documents and multiple verification steps. Blockchain-based trade finance platforms like Contour (backed by Citi, HSBC, ING, and Standard Chartered) digitalise these documents and allow all parties to view and verify them on a shared ledger. Processing time drops from seven to ten days to under 24 hours.
Payments infrastructure is the third area. SWIFT began testing blockchain interoperability in late 2023, aiming to connect private blockchain networks used by different banks into a unified messaging layer. The experiment involves over 30 financial institutions and addresses the fragmentation problem: currently, a bank on R3’s Corda cannot easily transact with a bank on Hyperledger Fabric.
Digital custody is the fourth. BNY Mellon, the world’s largest custodian bank, launched its digital asset custody platform in 2022. Fidelity, State Street, and Northern Trust followed. These platforms allow institutional investors to hold blockchain-based assets (tokens, digital bonds, fund shares) within the same custodial framework as traditional securities.
Internal Barriers to Adoption
Despite the business case, financial institutions face significant internal obstacles when exploring blockchain.
Legacy technology is the most common barrier. Many large banks run core systems built in COBOL on mainframes deployed in the 1970s and 1980s. Integrating a blockchain layer with these systems requires middleware, API adapters, and extensive testing. A bank cannot simply “switch to blockchain.” It must run parallel systems during a transition that can take years.
Governance and risk management slow decision-making. A bank’s blockchain initiative must pass through technology risk, operational risk, legal, compliance, and audit committees before reaching production. Each committee applies its own standards and may require modifications that add months to the timeline. JPMorgan’s Onyx took several years from concept to production deployment. Most banks move even more slowly.
Talent acquisition is a practical challenge. Blockchain engineering requires skills in distributed systems, cryptography, and smart contract development that are scarce and expensive. Senior Solidity developers command salaries of $180,000 to $350,000 in the US market. Banks compete for this talent against crypto-native companies, well-funded fintech startups, and DeFi protocols that offer token-based compensation.
Regulatory uncertainty adds another layer. Banks must ensure that any blockchain deployment complies with existing regulations for the jurisdiction and asset class involved. In the EU, MiCA provides a clear framework. In the US, the absence of comprehensive federal legislation means banks must interpret guidance from the SEC, CFTC, OCC, and state regulators, often receiving conflicting signals.
The Decision Framework
Financial institutions exploring blockchain tend to follow a consistent pattern. They start with a use case that has clear cost savings and limited regulatory complexity (usually repo trading or internal settlement). They deploy on a private, permissioned blockchain where they control participation. They run the system in parallel with existing infrastructure for 12 to 24 months. Only after the parallel run demonstrates reliability do they consider expanding to additional use cases or external counterparties.
This cautious approach explains why 83% of institutions are exploring blockchain but far fewer have it in full production. Exploration, for a bank, means funded research, proof-of-concept systems, and small-scale live deployments. It does not mean the institution has committed to replacing its core infrastructure.
North America holds 43.80% of the global blockchain market, per Fortune Business Insights. Blockchain-as-a-Service platforms account for 51.72% of revenue, reflecting the preference of financial institutions for managed infrastructure over custom builds. The exploration phase is not ending. It is deepening, with institutions moving from asking “does this technology work?” to asking “which of our operations should run on it first?”
