## How to settle an OTC trade when both parties are in different countries
Cross-border OTC settlement is where most of the real friction in this business lives. The trade itself — negotiating price, size, and terms bilaterally — is the part that professional desks have largely figured out. What trips up even experienced operators is the moment after the handshake: when two parties in two different countries, under two different banking systems, in two different time zones, need to exchange value simultaneously and irreversibly. That is where deals slow down, where exposure accumulates, and where a broker or advisor's commission can sit in transit longer than the trade itself took to negotiate. This article walks through exactly how cross-border OTC settlement works, what breaks it, and how professionals structure it to protect themselves and their clients.

## Why cross-border OTC settlement is structurally different

In a domestic OTC deal, both parties' banks operate inside the same payment system. Settlement can still be imperfect, but the mechanics are at least synchronized — same business hours, same currency, often the same clearing network. Cross-border changes every variable at once.

Settlement risk arises primarily during the settlement phase of cross-border payments, where time zone differences and independent settlement systems can expose parties to the full principal amount of the transaction for hours or even days. That is not a theoretical edge case — it is the everyday reality of any OTC deal that crosses a border. A buyer in Singapore and a seller in London are not simply separated by geography. They operate in different clearing windows, hold funds in different currencies, bank with institutions that may have no direct relationship with each other, and face regulatory frameworks that can interact unpredictably.

Without a central clearing house, a failure to deliver, late funding, or a last-minute credit event can turn a good quote into a realised loss, especially on T+0/T+1 or cross-border deals where cash and assets move on tight timelines. The OTC structure, which is its chief advantage for large and bespoke trades, is also what removes the safety net that exchange-cleared markets provide. There is no CCP standing between the two legs. There is no automatic netting. The vast majority of OTC transactions are settled bilaterally between the counterparties, rather than through clearing houses. That puts the full weight of operational execution — timing, sequencing, confirmation, and disbursal — on the professionals managing the deal.

## The core problem: two legs, two time zones, one sequence

The defining structural risk in cross-border OTC settlement has a name and a history. Settlement risk, also known as Herstatt risk, refers to the risk in financial transactions that one party will deliver the currency or asset it owes but fail to receive the expected delivery from the counterparty, potentially resulting in substantial credit and liquidity losses.

The event that named this risk is worth understanding in detail, because it is not historical curiosity — it is a direct illustration of what can happen on any bilateral cross-border deal today. On June 26, 1974, German regulators closed Bankhaus Herstatt at the end of the domestic business day in Cologne. The bank had accumulated massive foreign exchange losses. Counterparties in New York had already delivered Deutsche marks to Herstatt earlier that day, expecting to receive U.S. dollars in return when American markets opened. The dollars never arrived.

This risk arises primarily during the settlement phase of cross-border payments, where time zone differences and independent settlement systems can expose parties to the full principal amount of the transaction for hours or even days. The key word there is *principal*. This is not exposure to a mark-to-market loss or a spread move. Herstatt risk is unique because it exposes the full principal amount, not just profit or loss from price movements. Principal risk is regarded as the most serious risk in forex settlement because it exposes a party to the total value of the trade, not just a portion of it.

On a $10 million OTC trade between a US-based seller and a European buyer, the sequence looks like this in practice. The seller wires funds from their US bank. Those funds move through the US correspondent network and land — or are expected to land — at the buyer's European bank. But the buyer's payment in the other direction follows its own path, on its own timetable. Time-zone mismatches mean one currency may settle hours earlier than the other, creating a window where only one party has delivered. If a bank or institution becomes insolvent during the settlement window, the other party cannot recover funds easily. Cross-border delays caused by different banking systems, cut-off times, and holidays can cause asynchronous payments. For the duration of that gap, the party that moved first is fully exposed.

## How the correspondent banking layer compounds the delay

Most OTC professionals understand that a SWIFT wire is not an instant transfer. What is less understood is why — and why that matters specifically in cross-border deals where timing of payment acknowledgment matters to both sides.

The correspondent banking network underpinning most international transfers was built for a different era of transaction volumes, speed expectations, and cost of capital. It works, but at a price: settlement windows of one to five business days, during which capital sits in transit, generating cost without generating value. All the while, payment operators must maintain funded accounts across multiple currencies and markets to keep flows moving.

In a cross-border OTC deal, that latency is not merely inconvenient — it creates an exposure window during which one or both parties have performed, but settlement is not confirmed. A broker whose commission depends on funds clearing through an international wire is at the mercy of correspondent chain delays, intermediary bank cut-off times, and public holiday calendars in multiple jurisdictions. A deal that closes on a Thursday afternoon New York time may not have confirmed settlement in an Asian counterparty's account until Monday. Fiat leg settlement — the settlement of a transaction between an exchange and a bank — can take from two to five business days, depending on the type of withdrawal and bank infrastructure.

The length of that window is not the only variable. The number of hops through the correspondent chain matters too. A payment from a mid-sized US regional bank to a counterparty at a bank in Southeast Asia may route through two or three correspondent banks, each of which applies its own cut-off times, compliance checks, and processing queues. Wire transfers relying on the SWIFT network to move funds between banks across countries, while secure and globally recognized, often involve multiple intermediaries, resulting in high fees and settlement times of several business days.

For the broker or advisor structuring a cross-border deal, this is not an abstract concern. It affects when the trade is confirmed as fully settled, when each party can redeploy capital, and — most practically — when the professionals who arranged the trade actually get paid.

## What cross-border settlement actually looks like by trade type

Not all cross-border OTC deals settle the same way. The asset class, the jurisdictions involved, and the relationship between the parties all determine which settlement path is available and how much risk sits in the gap.

### Digital asset OTC trades

This is where cross-border settlement has evolved most dramatically. By using fiat-pegged digital assets such as USDT or USDC for settlement, OTC desks can operate on a 24/7 basis and settle trades within minutes rather than days. Once a stablecoin transfer is executed on-chain, it's settled without a need to wait hours or days for bank wires to clear. This reduces the settlement window from days to minutes, enabling counterparties to redeploy capital immediately.

The practical workflow for a cross-border digital asset OTC trade — say, a Singapore-based family office selling $8 million in Bitcoin to a European corporate treasury — typically runs as follows. The seller's desk agrees terms with the buyer's desk. A price is locked. The buyer transfers a stablecoin equivalent to the agreed purchase price to a wallet address provided by the seller's desk. Upon confirmed receipt on-chain, the BTC moves in the other direction. The entire cycle, from locked quote to confirmed settlement on both sides, can complete in under an hour. That is structurally impossible in any correspondent banking scenario for the same size.

Crypto OTC trading benefits from blockchain-based settlement mechanisms. Transactions settled on-chain can offer faster and more predictable finality compared to traditional financial infrastructure, as they are not constrained by banking hours or correspondent networks. For the broker or advisor who arranged the introduction between these two parties, this speed matters enormously. A trade that settles in hours rather than days reduces the period during which something can go wrong — and reduces the period during which their commission has not yet moved.

### Fiat-to-fiat cross-border OTC (currencies and structured products)

Here the mechanics are more constrained. A spot FX OTC transaction between two international counterparties — or any deal where both legs move through national banking systems — still operates within the constraints of those banking systems' settlement windows. In cross-border transactions like FX trades, settlement risk is exacerbated by the conventional two-business-day (T+2) lag between trade execution and final settlement, driven by time zone differences and payment system processing times, which creates an extended exposure window during which one party may pay out its currency without receiving the countervalue.

The professionals structuring these deals use a range of risk mitigation tools. Payment-versus-payment arrangements, where both legs are intended to settle simultaneously through a matched instruction system, reduce the principal exposure window. Netting agreements reduce the gross settlement flow when multiple trades exist between the same parties. But the fundamental architecture — national banking hours, correspondent chains, currency-specific cut-off times — still shapes the operational reality.

### Commodity and hard asset OTC trades

Cross-border settlement of physical commodity OTC deals adds a documentation layer on top of the payment layer. A physical gold trade between a counterparty in Switzerland and one in the UAE involves title transfer mechanics, storage location confirmation, and proof of delivery or transfer on top of the payment settlement. The payment and the asset delivery are two separate processes that must be coordinated — which is why the professionals structuring these deals spend as much time on operational sequencing as on negotiating the spread.

For these trades, the settlement timeline is typically negotiated as part of the deal terms. T+2 or T+3 settlement is standard, with each leg documented. The broker or advisor managing the deal needs to confirm that both legs are progressing before releasing their own involvement, and international bank holidays across the jurisdictions involved can compress or extend the practical window significantly.

## The role of the broker and advisor in cross-border settlement

The relationship between the counterparties is exclusively principal-to-principal. Brokers may be used to locate counterparties, but the brokers are not themselves counterparties to the transactions. That legal reality defines exactly where a broker's risk lives in a cross-border deal. They are not on the hook for settlement if a counterparty defaults — but they are also not protected from the practical consequence of that default: the commission they expected to receive may be attached to a deal that did not close cleanly.

The cross-border dimension makes this more acute because the confirmation chain is longer. In a domestic deal, a broker can often confirm settlement with a quick call to the closing agent. Across borders, confirmation requires coordinating with parties in different time zones using different banking systems, often with language barriers and different business-day calendars layered on top.

Experienced cross-border OTC professionals typically do several things to protect themselves and their parties here. First, they agree in writing — before the trade executes — exactly what "settlement confirmed" means in that specific deal: which wallet address, which bank account and SWIFT reference, which confirmation is the authoritative signal that value has moved. This avoids disputes about whether a correspondent bank acknowledgment counts as settlement or whether only a final credit to the beneficiary account qualifies.

Second, they ensure that their own fee mechanics are tied to a confirmable event. A broker whose commission triggers on "deal closing" when the deal involves an international wire transfer needs to know which event constitutes closing: trade execution? Payment initiation? Confirmed receipt? In cross-border deals, these events can be separated by days, and the distinction matters enormously for the person who needs to know when to expect payment.

Third, where the deal involves multiple professionals on the same side — a sourcing broker, a buy-side advisor, a local intermediary in the buyer's jurisdiction — the split mechanics need to be established before settlement, not resolved after the fact across three different international bank accounts. Post-settlement splits through bank wires introduce unnecessary friction, delay, and — in certain jurisdictions — compliance review.

## The jurisdiction and regulatory layer

Cross-border OTC deals always sit under at least two regulatory frameworks simultaneously, and sometimes more. A trade arranged by a US-registered broker between a UK-based seller and a Hong Kong-based buyer involves three sets of conduct rules, reporting obligations, and potentially licensing requirements. Regulatory frameworks vary by jurisdiction, making due diligence, compliance checks, and counterparty verification essential components of any OTC trading strategy.

OTC markets are regulated differently from standard exchanges. Rules vary by region, but the obligations for professional firms are clear: know your client, control risk, record activity, and report trades.

The practical settlement implication is that funds moving across borders in an OTC trade context often attract enhanced due diligence from the banking institutions handling the transfer. A $5 million SWIFT wire described as an OTC trade settlement may trigger a compliance review at the correspondent bank that adds one to three business days to the settlement timeline. This is not a failure of the trade — it is a standard feature of how international correspondent banks handle large-value cross-border transfers. Professionals structuring these deals build that buffer into the expected timeline and communicate it clearly to both sides.

Sanctions exposure is a specific risk in cross-border OTC deals that domestic deals largely do not present. A party who is unremarkable in their domestic market may appear on a restricted list in the jurisdiction of a correspondent bank handling the other side of the transfer. Rules vary by region, but the obligations for professional firms are clear: know your client, control risk, record activity, and report trades. Counterparty screening needs to happen before the trade, not during settlement — because discovering a sanctions issue mid-transfer can freeze the entire payment chain.

## When the deal involves multiple brokers across countries

A genuinely international OTC deal often involves professional intermediaries on both sides. A sourcing broker in the seller's country, a connecting desk that runs the deal, and a local relationship manager in the buyer's country may all have fee arrangements that need to be honored at settlement. In domestic deals, splitting the commission is a post-closing administrative step. In cross-border deals, it becomes its own miniature settlement problem.

Consider a $20 million OTC digital asset deal where a US broker sources the seller, a Singapore-based desk runs execution, and a Dubai-based advisor provides the buyer introduction. The total commission might be 0.4% — $80,000 — split three ways across three different jurisdictions. Executing those splits through international wires means three separate SWIFT transactions, three separate correspondent bank delays, three separate compliance reviews at the receiving banks, and — practically — three different settlement timelines for the three professionals who worked the deal.

Institutional clients may require same-day liquidity to respond to market shifts, manage FX exposure, or redeploy capital, but sluggish settlement processes can freeze capital. The same principle applies to the professionals facilitating those clients. A broker whose $26,000 share of a commission takes eleven business days to arrive via an international wire after a deal that settled in two hours on-chain has a legitimate operational problem — not a theoretical one.

This is exactly where Shaka earns its place in a cross-border OTC workflow. Before the deal closes, the professional running the deal configures a payment link: wallet addresses for each party that is owed a share of the proceeds, and the split percentages that reflect the agreed arrangements. When the deal closes, funds move onchain, directly to each wallet simultaneously, in a single transaction. There is no second-stage disbursal across international wires. There is no sequence of three SWIFT transfers each waiting on correspondent bank processing windows in different time zones. The broker in the US, the desk in Singapore, and the advisor in Dubai each receive their portion the moment the deal closes — final, confirmed, on-chain.

## Sequencing settlement correctly when both sides are offshore

The most common mistake in cross-border OTC settlement is treating it as a domestic settlement with some additional paperwork. It is structurally different, and the sequencing decisions made before the trade executes determine how much exposure each party carries.

The standard discipline for cross-border OTC settlement breaks into four phases.

**Phase one: pre-trade coordination.** Confirm settlement instructions before price is agreed. In a cross-border deal, confirming that a wallet address is correct, or that a bank account is active and properly designated, is not a formality — it is a risk control. Typos in SWIFT instructions and incorrect wallet addresses are the two most common causes of settlement failure in bilateral deals, and both are completely preventable at this stage.

**Phase two: locking the mechanics.** Agree what constitutes confirmed settlement for each leg. For an on-chain transaction, this is typically a specified number of block confirmations on the relevant network. For a fiat wire, this is typically the confirmed credit to the final beneficiary account — not the initiation of the transfer, and not the correspondent bank acknowledgment. With faster settlement cycles, the window in which one party is exposed to default risk narrows significantly. Choosing on-chain settlement for the legs that can move on-chain tightens this window considerably.

**Phase three: execution and monitoring.** Each payment includes a transaction ID, enabling built-in traceability. For on-chain legs, this is real-time and unambiguous. For fiat legs, it requires active confirmation with the banking institution, not an assumption that the wire will arrive on the expected day. Cross-border deals with fiat legs need a named point of contact at the correspondent bank, a SWIFT reference to track, and a clear escalation path if confirmation is not received within the expected window.

**Phase four: professional settlement.** Once the principals' legs are confirmed, the deal's professionals get paid. In a well-structured cross-border OTC deal, this step should not feel like a second transaction. It should be built into the deal's settlement mechanics from the start — with every recipient's wallet or account pre-specified and the split logic established as a condition of the deal, not an afterthought that gets resolved over email after both sides have moved on.

## The finality question

A trade that settles atomically means both currency legs clear simultaneously. That concept — atomicity, the property of a transaction where everything happens or nothing happens, with no intermediate state where one party has paid and the other has not — is the ultimate answer to Herstatt risk. Herstatt risk is the danger that one party settles its leg while the counterparty fails before reciprocating. An atomic settlement removes that danger entirely because there is no sequence — there is only a completed transaction or a transaction that did not execute.

On-chain settlement provides an immutable record, simplifying reconciliation and compliance audits without relying solely on bank statements. For the OTC professional, this is not just a settlement quality improvement — it changes the administrative workload after the deal. There is no waiting for bank statements to confirm receipt. There is no following up with a counterparty's back office to confirm that the wire was credited. The chain is the record, it is public and persistent, and it is available to both sides the moment the transaction is confirmed.

The professionals who run cross-border OTC deals well are not the ones who wait for banking infrastructure to catch up with their deal velocity. They are the ones who understand exactly where the latency lives in each corridor, who pre-negotiate the settlement mechanics with the same precision they bring to the price, and who ensure that every party who is owed a share of the deal proceeds — including themselves — has a confirmed, final, irreversible path to receive that money the moment the deal closes. The deal is the negotiation. Settlement is the profession.
