JPMorgan Chase vs. Citibank: The Battle for Blockchain Payment Infrastructure and the Tokenization Transformation of the Global Settlement System

In April 2026, the competitive landscape between JPMorgan Chase and Citigroup in blockchain payment infrastructure has attracted widespread market attention. Both banks have long dominated global cross-border corporate payments, handling trillions of dollars in funds, and are now extending this competition from traditional payment channels into blockchain-based tokenized payment systems.

JPMorgan continues to expand its first-mover advantage with its self-developed blockchain platform Kinexys (formerly Onyx). Since its launch in 2020, the platform has processed over $3 trillion in transactions, with an average daily volume surpassing $5 billion. Meanwhile, Citigroup’s tokenization service, Citi Token Services, has already covered more than 500 institutional clients, with an average daily processing amount of about $1 billion, and plans to launch institutional digital asset custody services within 2026.

Although the digital payment volumes of both banks are still far below their traditional systems, senior executives from both sides have stated that this marks the rapid arrival of a tokenized, programmable, 24/7 financial future.

Strategic Retrospect: From JPMorgan’s Self-Developed Platform to Citigroup’s Five-Year Acceleration

JPMorgan: A Decade of Deployment from Onyx to Kinexys

JPMorgan began R&D on blockchain infrastructure over a decade ago. In 2020, the bank officially launched the Onyx digital asset platform and JPM Coin deposit tokens, becoming the first major bank to introduce a proprietary blockchain payment system. Since then, the platform has undergone multiple iterations and upgrades, and was renamed Kinexys, positioning itself as an integrated blockchain infrastructure covering payments, tokenized assets, and securities.

In November 2025, Kinexys deployed JPM Coin on Coinbase-supported Ethereum Layer 2 network Base, marking the first time a bank deposit token was introduced into a public blockchain environment. In January 2026, JPM Coin was further expanded to the Canton network, becoming its second public chain deployment scenario. By April 2026, JPMorgan announced the appointment of former Goldman Sachs executive Oliver Harris to lead the Kinexys division, aiming to accelerate commercialization and Middle East market expansion. The platform’s average daily transaction volume has now exceeded $7 billion.

Citigroup: Five Years of Deep Cultivation and 2026 Acceleration

Citigroup’s blockchain infrastructure development began around 2021. Citi Token Services is now operational in the US, UK, Ireland, Hong Kong, and Singapore, supporting corporate clients to transfer tokenized deposits any day of the week, at any time.

Citigroup has connected to over 220 global payment networks and has a clear roadmap for transitioning from private blockchains to public chains. By the end of 2025, Citi partnered with Coinbase to explore digital asset payment capabilities for institutional clients. In February 2026, Nisha Surendran, head of Citigroup’s digital asset custody, officially announced at the World Strategy Forum that the bank will launch institutional Bitcoin custody services within 2026, aiming to “make Bitcoin operationally bank-grade.”

Data Showdown: Transaction Scale, Technical Architecture, and Trillion-Scale Market Potential

Transaction Scale Comparison

As of April 2026, JPMorgan’s Kinexys daily transaction volume has reached approximately $7 billion, significantly ahead of Citigroup. At the end of March, JPMorgan partnered with Mitsubishi Corporation to further push Kinexys’ daily volume toward $10 billion. Although Citigroup’s absolute scale remains conservative, its strategic differentiation is clear—beyond payment infrastructure, it is simultaneously building complementary capabilities such as digital asset custody and cross-asset collateralization, aiming to develop a comprehensive ecosystem.

Market Size Reference

Industry data shows that the blockchain market for financial services was approximately $6.98 billion in 2024, with an expected CAGR of 52.9% to reach about $58.2 billion by 2029. BNY Mellon predicts that by 2030, the total market size of stablecoins and tokenized cash will reach $3.6 trillion. Citigroup’s own research indicates that tokenized deposit annual transaction volume could reach $100 trillion to $140 trillion by 2030.

These figures suggest that JPMorgan and Citigroup’s combined current daily digital payment volume of about $8 billion is still in the very early stages relative to the projected future market potential, and the main battleground for competition remains undefined.

Divergence in Technical Architecture

JPMorgan adopts a “self-developed priority, public chain expansion” dual-track strategy. Kinexys centers on a self-developed permissioned chain, while also deploying JPM Coin on public chains via Base and Canton networks. The bank also plans to expand into private credit and real estate tokenization, upgrading Kinexys from a payment network to a comprehensive tokenization platform.

Citigroup, on the other hand, uses Citi Integrated Digital Assets Platform as a hub, constructing a hybrid architecture connecting fiat infrastructure with public chains. Its technical approach emphasizes “integration” rather than “disruption”—embedding blockchain as a foundational technology into existing banking operations rather than building an entirely separate system.

Divergent Perspectives: Deposit Tokens vs. Stablecoins

The most prominent difference between the two lies in their stance on stablecoins. Shahmir Khaliq, Citigroup’s global head of service business, explicitly expressed willingness to cooperate with clients using stablecoins for cross-border payments. Additionally, Citigroup’s research forecasts that stablecoin settlement volume could reach nearly $100 trillion by 2030 under baseline scenarios.

Umar Farooq, JPMorgan’s global head of payments, remains cautious. He pointed out that if stablecoin issuers bear risks similar to banks, they should follow similar regulatory rules. Some stablecoin issuers may adopt “light” compliance controls like KYC. JPM Coin is positioned as an “excellent alternative” to stablecoins, emphasizing its compliance infrastructure built over decades, including sanctions screening, AML controls, and regulatory reporting.

Calm Reflection: Commercial Motives Behind the Optimistic Narratives

Both banks’ executives send positive signals, but a fact-based review is necessary: First, current digital payment volumes are still tiny compared to traditional systems and do not generate substantial revenue. Second, JPMorgan’s criticism of stablecoins has commercial logic—since JPM Coin is essentially a deposit token, criticizing stablecoins’ compliance shortcomings highlights the advantages of bank-issued tokens. Third, Citigroup’s “open cooperation” narrative also involves pragmatic considerations—collaborating with crypto-native firms like Coinbase allows the bank to make lighter technical investments and leverage existing infrastructure to accelerate market coverage.

Deep Disruption: Chain Reactions in Traditional Payments, Regulation, and Customer Demand

Structural Challenges in Traditional Payment Clearing Systems

In a letter to shareholders in April 2026, JPMorgan CEO Jamie Dimon explicitly stated that new competitors based on blockchain—including stablecoins, smart contracts, and tokenized assets—pose structural challenges to core banking functions such as payments, trading, and asset management. Dimon warned that tokenization and near-instant settlement could directly compress bank intermediary revenues and provide alternatives to traditional deposits.

Shahmir Khaliq, head of Citigroup’s service business, also noted that as liquidity becomes more mobile, clients will expect greater flexibility in holding and moving funds. “If value can flow instantly elsewhere, it must be able to move seamlessly through our network,” he said.

Rapidly Evolving Regulatory Frameworks

The “Guidance and Establishment of the U.S. Stablecoin National Innovation Framework Act,” signed in July 2025, established a federal regulatory framework for payment stablecoins. In December 2025, the FDIC further approved rules allowing US banks to issue dollar-backed stablecoins, integrating stablecoins into the regulated banking system. These regulatory developments provide compliance certainty for bank-based blockchain payment infrastructure and accelerate traditional financial institutions’ investments in this field.

Institutional Demand Driving Infrastructure Upgrades

Nisha Surendran, head of Citigroup’s digital asset custody, pointed out that clients’ core demand is not directly operating wallets or private keys but gaining digital asset exposure within familiar banking systems. Citigroup’s solution is to incorporate Bitcoin into the same custody, reporting, and tax frameworks as stocks and bonds, providing SWIFT and API interfaces. Clients issue instructions, and the bank handles all clearing and settlement complexities.

This “bank-grade encapsulation” approach is becoming the mainstream paradigm for traditional financial institutions entering digital assets—integrating digital assets into existing operational frameworks rather than forcing clients to adapt to crypto-specific workflows.

Pathway Projection: From Dual-Track Competition to AI Agent Economy in Four Futures

Scenario 1: Convergent Competition with Parallel Tracks

In the next three to five years, JPMorgan and Citigroup will continue along the “deeply integrated self-developed” and “open cooperative ecosystem” paths respectively. However, as the market matures, these paths may partially converge.

JPMorgan has deployed JPM Coin on public chains Base and Canton, indicating that “self-developed” does not mean closed. Citigroup continues investing in its Citi Token Services infrastructure, showing that “cooperation” does not equate to abandoning autonomy. Under converging regulatory frameworks, the underlying capabilities of deposit tokens may narrow the gap, shifting competition focus from technical routes to customer coverage and ecosystem scale.

Scenario 2: Fusion of Stablecoins and Deposit Tokens

The “Guidance and Establishment of the U.S. Stablecoin National Innovation Framework Act” opens the door for banks to issue stablecoins, and deposit tokens already possess core stablecoin functions. Driven by regulation and market demand, these two forms may merge.

The FDIC has permitted US banks to issue dollar stablecoins, and Citigroup has expressed willingness to serve stablecoin cross-border payment clients. JPMorgan admits in its shareholder letter that stablecoins and tokenization are “structural challenges.” If regulations further clarify capital requirements and consumer protections for both tools, banks may offer both deposit tokens and bank-issued stablecoins, creating a multi-layered on-chain payment system.

Scenario 3: Cross-Border Pressure from Crypto-Native Players

The competition between JPMorgan and Citigroup should not be viewed solely as bilateral. Visa supports over 130 stablecoin-linked card programs across more than 40 countries; Stripe describes stablecoins as a “practical option” for cross-border payments, recording about $9 trillion in adjusted payment activity from October 2024 to October 2025.

If payment networks and fintech firms can build stablecoin payment ecosystems with lower friction, banks’ intermediary role could weaken further. The risk acknowledged by Dimon in his shareholder letter is a key driver behind JPMorgan’s acceleration of Kinexys commercialization.

Scenario 4: AI Agent Economy Catalyzing Infrastructure Needs

Nisha Surendran from Citigroup points out that the rise of AI agents autonomously executing trades—an “agent economy”—will fundamentally change the world within five years. Blockchain infrastructure is critical for enabling this scenario. If the AI agent economy scales before 2030, the demand for 24/7 programmable payment infrastructure will far exceed current capacities. This variable could dramatically alter the competitive landscape—success may depend less on current processing volumes and more on who can support exponential growth and complexity in transaction scales.

Conclusion

The competition between JPMorgan Chase and Citigroup in blockchain payment infrastructure is reshaping the role of traditional banks in the global payment system. Their divergent technical strategies—deep self-developed integration versus open cooperation—and their cautious yet accepting attitudes toward stablecoins reflect their organizational DNA and strategic judgment, offering two different evolution paradigms for the industry.

Currently, both banks’ digital payment volumes are a tiny fraction of traditional systems, and the outcome of this competition remains uncertain. More importantly, this race is driving structural changes: payments shifting from batch daily clearing to real-time on-chain settlement, asset custody evolving from isolated asset classes to cross-asset, cross-chain integration, and core banking functions migrating from “transaction window processing” to “continuous value flow orchestration.”

With the implementation of the “Guidance and Establishment of the U.S. Stablecoin National Innovation Framework Act,” rising institutional demand, and the approaching AI agent economy, the tokenization transformation of payment infrastructure is accelerating from experimental to operational phases. This is not only a commercial contest between two banks but a profound transformation of the global financial infrastructure paradigm.
