Most money today exists only as digital records. Yet sending a wire to family in another country can still cost around $50 in sender fees alone, and considerably more once intermediary and receiving banks each take a cut. It can also take several days to arrive. The problem is not that money travels on slow networks. The problem is the network itself. Our global financial system was assembled piece by piece, and that assembly built in structural inefficiency, disorganization, and fragmentation.
Coordinating payments, compliance, and risk between countries and institutions that cannot inherently trust each other is a genuinely hard problem. For a long time the patchwork we built was the best answer available.
Distributed ledger technology (DLT), the family of systems that includes blockchains, offers a way to upgrade the core of global financial market infrastructure (FMI, the plumbing beneath every transaction) while respecting the need for decentralized governance. It can make money move at the speed of information. This article lays out where legacy FMI falls short and how a DLT-based unified ledger could fix it.
The architecture we inherited
Modern cross-border payment rails were stitched together over decades. Every engineering decision solved a real problem: connect one more bank, one more country, one more currency. The result works, and it carries global trade every day. It is also a patchwork.
Two layers do the work. A messaging layer tells banks a payment is coming. A correspondent layer actually moves the value.
Most banks use the SWIFT ISO 20022 standard for messaging. When an originating bank (the sender’s bank) needs to tell a beneficiary bank (the receiver’s bank) that a transfer is on its way, a shared format lets the two understand each other. Given the sheer number of possible bank pairs, a common standard was the only workable option, so the world’s economies built one together.
Messaging is the easy part. Moving the money is not. Our money sits inside institutions with different rules, systems, and operating hours, and no single settlement system could sit above rival economic blocs without becoming a geopolitical weapon. So the value takes a different path. It routes through tens of thousands of correspondent banks.
A handful of large banks, JP Morgan, Citi, and Standard Chartered among them, act as connective nodes for smaller regional banks that cannot link to each other directly. Together they form a fragmented mesh with a viable path between almost any two banks on earth.
Consider a payment from a bank in Canada to a bank in Vietnam. The message arrives in seconds. The money may hop through several correspondent banks, each using its own channels, whether a domestic Real-Time Gross Settlement (RTGS) system or a batch process reconciled overnight. That chain, with separate operating hours, compliance checks, and fees at every step, is what makes cross-border payments slow and expensive. Settlement finality today is a legal and operational construct layered on top of many eventually-consistent bank databases. It is not a property of the money itself.
A single transfer, two very different speeds
Messaging arrives in seconds. Value takes several days, paying a fee at every correspondent hop.
The cost of the system we have
The correspondent model made global commerce possible. It also taxes everyone who uses it.
Banks hold large buffers of idle liquidity to keep payments flowing. Settlement windows stretch across days. Whole teams exist to keep transactions from breaking mid-route. The failure modes are serious. Herstatt settlement risk, where one side of a currency trade pays out and the other never does, sits alongside failed trades, duplicate payments, and reconciliation errors that ripple outward through the system.
The cost is measurable. The World Bank puts the global average cost of sending a remittance at about 6.65 percent, more than double the 3 percent target the G20 set for 2030. Without a way for many independent institutions to agree on the truth quickly, reconciliation delay and fees are interest the world keeps paying.
The unified ledger
The Bank for International Settlements (BIS) is the central bank for central banks. For most of its history it played a quiet role, issuing soft recommendations for its members. Now it is trying to design a fix, and it calls that design the unified ledger.
A unified ledger puts a nation’s financial market infrastructure and assets on one shared platform built on DLT and tokenization. Assets stop being static entries in separate ledgers. They become programmable digital representations, where transfer, settlement, and compliance are written in code and happen at once.
Almost anything can be tokenized: central bank money, commercial bank deposits, debt securities, equities, real estate, and other real-world assets. DLT lets government, asset issuers, regulators, and users share one platform without handing control to a single operator. On that platform, tokenized assets settle immediately, at the speed of the message that describes them.
Two national ledgers, one instant settlement
Value settles across borders at the speed of the message that describes it. Each country keeps its own ledger, with no central operator in the middle.
The larger idea is to connect the unified ledgers of many countries, replacing the messaging-and-correspondence workaround in place today. That integration could take several forms. The point that matters is simple: money can move instantly across borders without a central operator in the middle. Each country keeps control of its domestic assets on its own ledger and still takes part in moving value across borders. The governance and trust model that works today survives. The reconciliation cost and delay do not.
Open problems
The unified ledger is still a concept, not a finished design. The BIS calls tokenization the third major step in the evolution of the financial system and the unified ledger its venue, but when and how countries build one remains open.
Governance is the hard question. A single platform hosting a nation’s core infrastructure looks nothing like today’s arrangement of governments, regulators, a central bank, chartered banks, exchanges, clearinghouses, and payment rails. Each country has to decide who admits participants and who is allowed to change the rules.
Design matters just as much. Assets and ledgers have to preserve the singleness of money, the principle that a dollar is worth a dollar in every form it takes. Lose that property and the whole thing frays.
No country will rebuild its payment systems in one move. The likely path is gradual, a hybrid where tokenized assets and DLT run alongside existing rails, adding instant settlement, fewer intermediaries, and compliance written in code. Even a partial unified ledger changes what is possible. Users could hold and trade many assets and products in one shared venue, anywhere in the world.
Building it on Canadian terms
For Canada, the question is not whether this shift happens. It is who builds the rails, and on whose terms.
Canada is already modernizing its plumbing. Payments Canada is standing up the Real-Time Rail, an always-on system that settles domestic payments in seconds. That solves speed inside our borders. It does not answer the cross-border problem, and it does not put Canadian assets on a programmable ledger.
There is a real risk in waiting. If tokenized settlement matures elsewhere first, Canadian value ends up moving on foreign platforms and foreign stablecoins, most of them denominated in US dollars. That trades one dependency for another and hands a lever over Canadian money to systems we do not govern. Sovereignty in payments is not abstract. It decides who sets the rules, who sees the data, and who can switch the rails off.
The alternative is to build our own. A Canadian unified ledger would bring central bank money, commercial bank deposits, and tokenized assets into one venue governed here, aligned with Canadian regulators from the start rather than retrofitted to rules written abroad. This is the work Transactix is doing. The Open Value Network™ is settlement infrastructure built for this model, and CADX™, a Canadian-dollar-backed stablecoin, is money that can move on it: programmable, compliant, and instant. Canadian dollars, on rails Canada controls, connected to the rest of the world on equal footing.
That is what moving value on Canadian terms means. Not a wall around the Canadian economy. A seat at the table, with control of our own ledger.
The work ahead
Distributed ledger technology has made it possible to move money as fast and as cheaply as information. The global financial system can adopt it without abandoning the decentralized trust model that holds the current system together. Each country keeps its ledger. The ledgers talk to each other.
The technology is here. What remains is architecture, and the will to build it.
