Cross-border payments remain a critical yet challenging component of the global financial system. Despite technological advancements, international money transfers are often slow, expensive, and lack transparency. These inefficiencies stem from deep-rooted structural issues—particularly the fragmented trust networks that underpin how money moves across borders. This article explores how digital innovation, especially tokenized money and decentralized marketplaces, can transform cross-border payments by redefining trust, reducing reliance on legacy intermediaries, and enabling more direct, efficient value exchange.
The Role of Trust in Modern Payment Systems
At its core, modern money is a system of credit relationships. Whether it’s central bank currency, commercial bank deposits, or stablecoins, each form of money represents a liability backed by trust. Users must trust that issuers will honor redemption, while issuers must trust users to comply with anti-money laundering (AML) and counter-terrorism financing (CFT) regulations.

This mutual trust forms what economists call a trust network—a web of verified relationships that enable transactions. Within a single country, this network is simplified by the presence of a central bank, which acts as a trusted intermediary through real-time gross settlement (RTGS) systems and regulatory oversight. This allows different banks to transact seamlessly using central bank reserves as a common settlement asset.
However, across borders, no such universal trust anchor exists. Instead, transactions rely on correspondent banking relationships (CBRs)—bilateral agreements between banks in different countries. These links are costly to establish and maintain due to compliance burdens, credit risk, and foreign exchange volatility. As a result, many financial institutions—especially in lower-income economies—are excluded from global payment networks.
Why Cross-Border Payments Are So Inefficient
Three major frictions make cross-border payments inherently inefficient:
- Limited Trust Links: Without a central trust mechanism like a central bank, banks must build individual relationships with foreign counterparts. The cost of due diligence and ongoing monitoring creates high barriers to entry.
- Fragmented Infrastructure: Unlike domestic systems where RTGS platforms ensure finality, international payments depend on messaging networks like SWIFT without integrated settlement. Funds don’t truly “move” until manually reconciled.
- Currency Conversion Complexity: Exchanging one currency for another involves foreign exchange markets that are often illiquid for emerging market currencies, leading to wide bid-ask spreads and higher remittance costs.
These challenges are particularly acute for lower-income countries. According to IMF research, higher compliance costs have led many global banks to terminate CBRs with institutions in developing economies—a trend known as de-risking. This exclusion raises transaction fees and delays, disproportionately affecting migrant workers sending remittances home.
Two Traditional Models of Cross-Border Settlement
Historically, international payments operate under two primary models:
- The Credit Model: One bank extends a short-term loan (an IOU) to another in exchange for crediting the recipient’s account. This creates counterparty risk and requires strong bilateral trust.
- The Pre-Funding Model: Banks maintain pre-funded nostro accounts abroad to facilitate outgoing payments. While this avoids credit exposure, it ties up capital and exposes banks to foreign exchange risk.
Both models reinforce a concentrated market dominated by large global banks capable of bearing these costs—limiting competition and keeping prices high.
Central Banks as Intermediaries: Swap Lines and Their Limits
In some cases, central banks step in where commercial institutions hesitate. Through currency swap lines, central banks provide liquidity to each other during times of stress. For example, during the 2008 financial crisis, the U.S. Federal Reserve established temporary dollar swap facilities with several major central banks.
Empirical evidence shows that swap lines reduce foreign exchange bid-ask spreads—an indicator of market liquidity—by up to 20%. Lower spreads translate directly into cheaper remittances: a 10% increase in spread levels raises the cost of sending $200 by about $0.15.
However, swap lines are limited by geopolitical proximity and historical ties. Most exist among advanced economies or regional blocs, leaving many developing nations without access. Establishing broader multilateral arrangements faces political and risk-sharing hurdles.

Tokenized Money: Redefining Trust and Interoperability
Digital innovation offers a path beyond these constraints. Tokenized money—such as central bank digital currencies (CBDCs), tokenized bank deposits, or regulated stablecoins—represents a fundamental shift in how value is recorded and transferred.
When money is tokenized on a shared ledger (typically permissioned), ownership is verified cryptographically rather than through institutional trust. Once a user receives the private key to a token, they control it outright—settlement becomes final and trustless in execution.
Crucially, while transactional trust shifts from institutions to technology, value trust remains essential:
- Recipients must be confident the token can be redeemed at face value.
- Issuers must verify user identities and monitor transactions for compliance.
To manage this balance, new intermediaries called gateways emerge—digital wallet providers or regulated platforms that verify both issuer credibility and user compliance. Gateways mutualize trust: instead of every user evaluating every issuer, they rely on a few trusted gateways that pre-vet tokens.
This drastically reduces the number of trust relationships needed—from n × i (where each user trusts each issuer) to roughly n + i, where users trust gateways and gateways trust issuers.
A Global Marketplace for Digital Money
Building on tokenization, this article proposes a cross-border digital marketplace where users can directly exchange tokenized currencies without relying on correspondent banks.
Here’s how it works:
- Interoperability via Multiownership: A sender holding Token A can pay a recipient who only accepts Token B—if both gateways recognize and hold both tokens. The recipient receives Token A but can instantly convert or spend it if their gateway supports it.
- Exchange via Market Makers: If direct conversion isn’t possible, decentralized market makers step in. Using smart contracts (e.g., hash-time locked contracts), they facilitate atomic swaps—ensuring both legs of a trade settle simultaneously.
- Liquidity Pools: Inspired by decentralized finance (DeFi), automated liquidity pools allow users to deposit pairs of tokens (e.g., USD Coin and Khmer Riel Token). Traders swap against the pool, paying small fees that reward liquidity providers.
This model eliminates the need for long chains of correspondent banks. Market makers don’t need exclusive bilateral relationships—they just need access to the platform and sufficient capital in both currencies.
Advantages Over Traditional Systems
- Lower Costs: No trapped liquidity or bilateral credit lines mean reduced capital requirements.
- Greater Competition: Any qualified entity can become a market maker, increasing price efficiency.
- Faster Settlements: Transactions settle in seconds or minutes via smart contracts.
- Enhanced Transparency: Real-time pricing and audit trails improve accountability.
Moreover, central banks could participate directly by issuing CBDCs on the platform or providing liquidity during periods of stress—effectively creating programmable swap lines.
Frequently Asked Questions (FAQ)
Q: What is tokenized money?
A: Tokenized money is a digital representation of value recorded on a blockchain or distributed ledger. It can represent fiat currency (like a dollar-backed stablecoin) or central bank money (CBDC), enabling programmable, peer-to-peer transfers.
Q: How does a digital marketplace improve cross-border payments?
A: By allowing direct exchange of tokenized currencies through smart contracts and decentralized market makers, it removes reliance on correspondent banks, reduces settlement time from days to minutes, and lowers transaction costs.
Q: Can this system work for all currencies?
A: Yes—especially when supported by regulatory alignment and standardized gateways. While major currencies may see faster adoption, emerging market currencies benefit most by gaining access to deeper liquidity pools.
Q: Who would operate such a marketplace?
A: It could be public (led by international organizations), private (developed by fintech firms), or hybrid (regulated public-private partnerships). Open governance and interoperability standards would be key to widespread adoption.
Q: Is this model secure?
A: Security depends on robust cryptography, sound smart contract design, and strong KYC/AML enforcement at gateway level. Unlike traditional systems vulnerable to counterparty failure, settlement finality is built into the protocol.
Q: How does this affect remittance costs?
A: By cutting out multiple intermediaries and reducing foreign exchange spreads through competitive market making, this model could reduce remittance costs significantly—potentially below the UN Sustainable Development Goal target of 3%.
The Future of Global Payments
The shift toward tokenized money isn’t just technological—it’s structural. It redefines how trust is established, how liquidity is provisioned, and how value flows across borders. A global digital marketplace for tokenized currencies offers a scalable solution to the inefficiencies that have long plagued cross-border payments.
While challenges remain—including regulatory coordination, cybersecurity, and equitable access—the foundation is being laid through pilot programs like Project Mariana (BIS) and growing interest in CBDCs worldwide.
