On a Saturday in August 2025, something happened that should have driven every cryptocurrency group on the internet crazy. Bank of America, Citadel Securities, the Depository Trust & Clearing Corporation (DTCC), and Societe Generale settled a repurchase (repo) transaction of U.S. Treasury bonds in real time over the weekend using blockchain.

To put it simply, a repo is one of the most fundamental transactions in institutional finance: one party sells government bonds to another and agrees to buy them back the next day, usually to raise short-term overnight cash.

This is the "pipeline" of the financial system. Banks, hedge funds, and central banks utilize repos daily to manage liquidity, with trillions of dollars flowing in this market. For the first time in history, such transactions achieved near-instant atomic settlement on the blockchain outside of market hours, with participants being the largest financial institutions in the world.

Eight months later, on April 20, 2026, Japan's Central Clearing House JSCC, Mizuho Financial Group, Nomura Holdings, and Digital Asset launched a proof of concept (PoC) to move Japanese government bonds (JGBs) as collateral onto the Canton Network blockchain.

JGBs are one of the most important financial instruments in Asia, with a circulating value of over $90 trillion, making them the most widely used single collateral asset in the institutional market in the region. When banks and hedge funds across Asia need to provide collateral for their leveraged positions, JGBs are typically the first choice. Now, the entire collateral system is migrating on-chain.

This may well be the most significant blockchain news of 2026.

This article will analyze why JGBs are the most suitable assets to be tokenized first, why Canton Network continues to win institutional orders while public chains vie for retail traffic, and how "24/7" collateral settlement is changing global over-the-counter trading.

Why JGB? Why now?

For decades, Japan has tried to make the yen a global reserve currency, but this ambition has never truly materialized. Even today, the yen accounts for only about 4-6% of global reserves, lagging behind the dollar, euro, and even the pound.

However, during this process, something unexpected happened: Japanese government bonds became one of the fastest-growing collateral assets on Euroclear's Collateral Highway, the infrastructure for moving collateral between major global financial institutions. The foreign ownership ratio of JGBs has risen to about 11.9%, with approximately ¥144 trillion held by institutions outside Japan.

In institutional finance, collateral is everything. Every leveraged position, every derivatives trade, every repo requires high-quality assets as collateral. Supported by the world's third-largest economy, JGBs have virtually no default risk, making them one of the few qualifying assets globally. When a hedge fund in Singapore establishes a leveraged position or a bank in London covers its derivatives exposure, JGBs are often used as collateral.

The most important infrastructure win for cryptocurrency is happening within traditional finance. In a situation where Japan has never won the "currency war," JGBs have already become the operating infrastructure of institutional finance in Asia.

The problem is that the entire collateral system still operates under a structure that dates back to 1995. The transfer of JGB collateral between two institutions must go through layers of ownership: at the top is the Bank of Japan (BOJ), then Hofuri (the Japanese securities depository), followed by custodian banks, and then sub-custodian banks. Each layer must reconcile separately and operates only during Tokyo's business hours (approximately JST 9 AM to 3 PM).

A collateral transfer that should take only seconds ultimately takes several days. During these days, the collateral is in a "frozen" state. If a trading desk in New York needs to use it at 10 PM, it must wait for Tokyo to wake up. A study by GFMA (Global Financial Markets Association) and Boston Consulting Group (BCG) estimates that blockchain could free up $100 billion in trapped collateral globally; for a bank with $100 billion in daily repos, tokenized settlement could save $150 million to $300 million annually in operational costs alone.

There is something unsettling for Japan: the U.S. has already taken action.

DTCC, which manages $99 trillion in U.S. securities and handles $3.7 quadrillion in transactions annually, partnered with Digital Asset in December 2025 to tokenize U.S. Treasury bonds on the Canton Network. This means that the core of U.S. securities infrastructure is moving towards 24/7 tokenized settlement.

Broadridge is already processing $354 billion in tokenized Treasury repo transactions daily on the same network; JPMorgan's Kinexys has processed over $1.5 trillion in cumulative transactions through its on-chain payment pathway. U.S. Treasuries are rapidly becoming "available anytime, transferable anytime" collateral, while JGBs remain locked during Tokyo's office hours.

If you are a global fund manager needing collateral for a margin call at 2 AM, if you could choose between instantly settling tokenized U.S. Treasuries or waiting until Tokyo opens six hours later to move JGBs, I believe you would choose U.S. Treasuries every time.

If this choice were amplified to thousands of trading desks, JGBs would face the risk of losing their status as "top collateral." For a country with sovereign bonds deeply intertwined in the Asian financial collateral system, this becomes a matter of survival. The four companies participating in the JGB on-chain trial used the word "urgent" in their press release. Considering the pace of evolution of U.S. infrastructure, it’s hard not to agree.

Why Canton Continues to Win

When Japan's JSCC had to choose a network for JGB collateral, they selected Canton—the very chain that DTCC, Broadridge, and JPMorgan are already using. The reason is that sovereign bond collateral has extremely stringent requirements on the network.

Sovereign bond collateral has a set of specific needs that most blockchains cannot meet. When Mizuho Bank transfers JGB collateral to a counterparty in London, the transaction must comply with Japan’s Book-Entry Transfer Act. Blockchain records need to maintain legal synchronization with Hofuri's official registry.

Each party in the transaction (from the clearing house to the custodian to the counterparty) can only see data authorized for viewing under Japanese and international securities laws. Furthermore, the entire process requires atomic settlement, meaning collateral and payment must move simultaneously; otherwise, neither moves.

This is an extremely complex set of constraints. The reason Canton was chosen is that its architecture is designed to address these issues. Each institution runs its own ledger, and cross-institution transactions only synchronize the data that each party is authorized to view. Smart contracts written in Digital Asset’s Daml language dictate who can see what and who must authorize at each step.

Thus, when JSCC, Mizuho, and Nomura conduct JGB collateral transfers on Canton, the clearinghouse sees the full picture, Mizuho sees its side, and Nomura sees its side, with no one seeing what they should not see. Canton is now the only network globally that allows the three major sovereign bond collateral pools (U.S. Treasuries, Japanese government bonds, European bonds) to move freely across borders, in real-time, 24/7. No other networks (public or private) come close to this capability.

What does "24/7" collateral really change?

Most reports about tokenized on-chain settlement stop at "it’s faster." But speed is just the beginning; the real transformation lies in the behavior of the system under stress.

Consider what happened during the COVID-19 pandemic in March 2020. The market crashed, volatility soared, and initial margin requirements for stock futures jumped by 100% within weeks. Funds that could not meet margin calls were forced to sell assets to raise cash.

However, selling assets in a declining market drives prices down, triggering more margin calls, which in turn forces more selling. This feedback loop is one of the most dangerous dynamics in finance, nearly bringing down the system during the U.K. LDI pension crisis in September 2022.

How 24/7 tokenized settlement changes this situation:

• Direct collateral: Currently, when facing a margin call, most funds must sell assets first to obtain cash. With on-chain collateral, funds can directly pledge JGB or U.S. Treasuries to meet the requirement without converting to cash first. The "forced selling cycle" consequently weakens, as fewer institutions will dump assets in a falling market just for liquidity.
• Solving the "give first, receive later" problem: In traditional repos, the cash lender first pays out, receiving collateral in return later. During this window period, one party is exposed to risk. Banks account for this "intraday exposure" in their haircuts and financing costs.
• Atomic execution: Through on-chain atomic settlement, both ends of the transaction (collateral and cash) move simultaneously. Santander tested this in December 2024, executing intraday repos of $50 million and €50 million on JPMorgan’s Kinexys, automatically closing the positions three hours later. Intraday repos that once required complex third-party arrangements or credit commitments are now routine.

More significantly, at the Canton demonstration in January 2026, the London Stock Exchange Group (LSEG) introduced its Digital Settlement House (DiSH) into the transaction. DiSH uses tokenized commercial bank deposits as cash, rather than stablecoins.

This is because banks will not use USDC to settle billion-dollar transactions—USDC is a private note, not "money good." DiSH tokens represent actual deposits from regulated banks and can be transferred on-chain 24/7. This solves the cash leg problem, which is the last piece of the puzzle for institutions. Now, Japan intends to integrate JGBs into this same infrastructure.

What This Means

If the JGB experiment is successful, and U.S. Treasuries are already live while European sovereign bonds are in demonstration, then in my view, Canton is starting to resemble the next SWIFT.

This is a single network that is becoming the default layer for the cross-border movement of the world’s most important collateral. Just like SWIFT, once a sufficient number of institutions join, exiting becomes nearly impossible. Network effects compound. Each new category of sovereign bonds joining will benefit existing participants and make it harder for newcomers to compete.

I think this is worth pondering. We have spent years in the crypto space debating decentralization, worrying about single points of failure, constructing a system that no single entity can control. And now, the most significant blockchain deployment in history is converging into a single permissioned network managed by the same set of institutions that run global finance.

Is this good or bad? It depends on what you believe the significance of all this is. If the goal is to improve the efficiency of capital markets, reduce settlement risks, and unlock hundreds of billions in trapped collateral, then it is indeed working. If the goal is to weaken the power of existing financial institutions, then it is doing the exact opposite—the original gatekeepers have simply replaced themselves with more advanced infrastructure.

I don’t think this makes it any less important. Completing the settlement of government bonds in a blockchain-based, 7x24, cross-border, atomic settlement financial system represents a real upgrade in how global finance operates. But I do think it is worth being candid about what kind of upgrade this is—that it is a revolution of efficiency: the pipeline has been rebuilt, but the plumbers are still the same people.
