# How to agree a reference price and lock it before settling

A practical guide for settlement professionals on how reference prices are agreed and protected in OTC deals, and how onchain routing delivers the certainty that bilateral negotiation alone cannot.

---


In every OTC deal, there is a moment when a number becomes real. Two parties — or five, or ten — look at a screen, a data feed, a voice-quoted rate, or a model output, and one of them says: *that is the price we are transacting on.* The other side agrees. Someone writes it down.

That moment is the reference price agreement. Everything that follows — the legal documentation, the disbursement instructions, the wires, the distribution to brokers and agents and advisors — depends on that number staying fixed and authoritative from the instant both sides say yes to the instant the last payee receives their share. The gap between those two moments is where deals bleed.

This article is for the professionals who manage that gap: settlement agents, closing attorneys, OTC desk operators, escrow officers, brokers working multi-party structures, and anyone responsible for ensuring that what was agreed on the trade date is what gets paid on the settlement date. It is a practical explanation of how reference prices are constructed and protected, where the common failure points sit, and how the settlement flow itself — not just the price negotiation — can be made certain.

## Why the reference price is not simply "the price"

In an exchange-traded market, the execution price and the settlement price are effectively the same thing, determined by an order book in real time and recorded centrally. Exchanges concentrate liquidity in a single public book — you get standardised contracts, transparent prints, and a reference price that is easy to audit.

OTC is different in every important respect. Prices form through bilateral negotiation, not an open auction. Desks negotiate size, price method, and settlement to suit the mandate, then execute discreetly. That flexibility is the reason the OTC market exists and the reason institutional flows continue to migrate toward it for any ticket large enough to move a public book. Institutions and whales prefer OTC for privacy and price certainty: a $10M buy on a public exchange would move the market, but the same trade OTC executes at a single negotiated price.

But bilateral negotiation introduces a problem that exchange execution eliminates by design: the reference price is only as durable as the documentation and the process that surrounds it. Before the trade is confirmed in writing, the number exists in two people's memories and a chat log. After the confirmation is signed, the number is contractually fixed. The period in between — often measured in minutes on a live deal, but sometimes in hours across time zones — is the first vulnerability.

The second vulnerability is the gap between price lock and actual settlement. In traditional financial markets, there is a delay between when a trade is agreed upon and when it is officially settled. This gap, often lasting two business days, creates a significant problem: counterparty risk. Counterparty risk in OTC is the risk that the other party fails to deliver what was agreed. In a bilateral trade, there is a window between execution and final settlement during which one side has committed, but the other has not yet delivered.

Understanding both vulnerabilities — the pre-confirmation window and the post-confirmation execution window — is the starting point for building a settlement process that professionals and their clients can rely on.

## The mechanics of reference price construction

Before a price can be locked, it has to be built. In practice, OTC professionals use a small number of methods, and the choice of method matters because it determines how the locked number can later be verified.

**Volume-weighted average price (VWAP).** The desk references the volume-weighted average price across several exchanges, adding a spread for liquidity and risk. VWAP-based pricing is common in crypto OTC and commodity forwards because the calculation is reproducible — any party with access to the same underlying feed data can reconstruct the price. For settlement purposes, this reproducibility is valuable: a dispute about whether the agreed rate was correctly applied can be resolved by running the same calculation against a timestamped data snapshot.

**Exchange settlement prices.** For energy and many derivatives, the reference is the official daily settlement published by an exchange — a number set by the exchange's own procedures and available to every market participant simultaneously. The price that you see at the end of the day on the exchange's price screen or in the data providers' newsletter is the value that is plugged into the price formula that you agreed contractually. This method entirely removes the question of whose quote applies, which is why sophisticated corporate buyers increasingly prefer it. The trade-off is that settlement prices are backward-looking: you agree today that tomorrow's or Friday's settlement print will define your rate, which means accepting some residual uncertainty about where that print will land.

**Live OTC quotes with a validity window.** This is the most common method for spot-like transactions. The supplier receives the request and, based on the price level observed at that moment, provides a price quote that is sent to the client. On this quote, a validity is indicated — for example, 30 minutes. This means that within that timeframe the client needs to decide whether they fix or not. The validity window is not a courtesy — it is a risk management mechanism for the quoting party, who has typically hedged against the rate in the underlying market the moment the quote is issued.

**Negotiated fixed price.** In private market transactions — commercial real estate, business acquisitions, structured commodity contracts — the parties simply agree a number. No feed, no model, no exchange print. The number lives in a term sheet, a letter of intent, and ultimately a purchase agreement. Here the reference price is the most durable of all in one sense (no market can move it after signing) and the most fragile in another (the gap between signing and funding can span weeks, during which the economic circumstances of one or more parties may change substantially).

Each method creates a different documentation requirement and a different set of post-agreement risks. Whatever method is used, the goal is the same: produce a number that every party to the transaction — buyer, seller, broker, agent, lender, settlement agent — can point to as the authoritative basis for every calculation that follows.

## The confirmation: from verbal agreement to locked reference

The moment the price is agreed verbally or electronically, the clock starts on getting it into writing. This is not bureaucratic formalism. Once the quote is accepted, the trade is locked. Both parties have agreed on the price, the asset, the amount, and the settlement method. For institutional OTC desks, this confirmation is typically documented immediately and forms the basis of the post-trade record.

For structured OTC derivatives, the confirmation references a master agreement — most commonly an ISDA Master Agreement — which pre-defines what happens if a party defaults, how disputes are resolved, and what the close-out mechanics look like. The market standard for OTC derivative documentation is the ISDA Master Agreement. The master contract is made up of a common core section and schedules containing adjustable terms that can be agreed upon by both parties. The terms specify contractual obligations such as netting, collateral, termination events, the definition of default, and the close-out process.

For less-structured commercial transactions — the ones where a broker is coordinating between a buyer, a seller, and a chain of advisors who all need to be paid at closing — the confirmation is often as simple as a signed term sheet or an exchange of emails that both parties have initialed. The legal weight of that document varies by jurisdiction, but the practical importance is constant: a written confirmation is the moment the reference price stops being a negotiating position and starts being a legal obligation.

What does a well-drafted price confirmation contain?

1. **The reference price itself**, expressed as a specific number, not a range or a formula that still needs to be applied.
2. **The methodology used to derive it** — which feed, which timestamp, which model, which exchange print — so that any recalculation can be traced.
3. **The currency and denomination** — particularly important in cross-border transactions where the same notional can mean different things in USD (1 USD is ~AUD 1.56 at the time of writing) or any other settlement currency.
4. **The settlement date and mechanism** — what happens if that date passes and settlement has not occurred.
5. **The distribution of proceeds** — who receives what share of the total, expressed as a fixed dollar amount or a confirmed percentage, and to which account.

That last point deserves more attention than it typically receives.

## The distribution problem: multiple parties, one reference price

In a simple bilateral trade, fixing the reference price is most of the work. There is one buyer, one seller, one number, two wires. The risk is real but the mechanics are manageable.

Most professional OTC transactions are not simple. A commodity forward has a broker on each side and a settlement agent coordinating the cash legs. A private business acquisition has a seller, a buyer, a lender disbursing partial proceeds, legal counsel for each party, a facilitating broker, and potentially a referral agent who negotiated the introduction. A commercial real estate closing has a title company executing a settlement statement that may list a dozen line-item payees.

A commission disbursement authorization is the document that tells the title company or closing agent exactly how to split commission payments at a real estate closing. It spells out who gets paid, how much each party receives, and where to send the funds. Without a correct CDA, the title company will not release commission dollars — and closing stalls.

The distribution agreement — whether it is called a CDA, a settlement statement, a disbursement schedule, or something else — is the companion document to the reference price confirmation. Together, they answer two questions: *what is the total amount* and *where does each dollar go?*

The problem is that these two documents are often created and controlled by different parties, on different timelines, and sometimes without explicit cross-referencing. A reference price may be locked on Monday. The distribution schedule may be finalized on Wednesday. If the gross amount shifts between Monday and Wednesday — because a lender adjustment, a prorated item, or a late credit changed the net proceeds — the distribution schedule must be updated, re-confirmed by all parties, and re-signed before settlement. In practice, this re-confirmation loop is where deals slow down and disputes start.

The fight is rarely about the math. It is about what was agreed to and what can be proven. Teams operating without written split agreements, or with agreements that do not address referral scenarios, mid-transaction departures, or dual-income splits, are exposed.

<span class="callout-label">The structural answer</span>
<h4>Lock the reference price and the distribution schedule simultaneously</h4>
<p>Treat the reference price and the distribution schedule as a single document, or at minimum as two documents that explicitly reference each other and are locked simultaneously. When both are confirmed at the same moment, by all parties, the risk of a post-lock divergence is eliminated. The settlement agent's job becomes execution, not further negotiation.</p>

## The settlement gap: price is locked but money is not yet moved

Even with a clean reference price and a locked distribution schedule, there is still the gap between agreement and payment. Between agreement and settlement, the risk that your counterparty fails to deliver is carried by a very specific stack: a credit department that decided how much exposure to allow you, an ISDA master agreement that defines what happens if you default, collateral posted against the position, and, at the bottom of everything, a court system that can seize assets from a legal entity.

For institutional OTC desks with established counterparty relationships, this risk is managed through pre-agreed credit lines, collateral frameworks, and rapid confirmation cycles. Settlement terms, including whether settlement is simultaneous or follows a short clearing window, are usually agreed during account onboarding rather than negotiated on a per-trade basis. This keeps execution fast and removes ambiguity at the point of trade.

For less-structured commercial transactions — and for the professionals coordinating them — the gap is managed through a combination of legal instruments (purchase agreements, settlement statements, irrevocable instructions) and process discipline. The question a good settlement agent always asks is: *at what point does each party have no practical ability to walk back their commitment?* For the buyer, it is often the moment funds clear into the settlement account. For the seller, it is the moment title or the asset is irrevocably transferred. For the broker or advisor, it is the moment the disbursement instruction has been signed by all principals.

The goal is to compress these moments into a single, simultaneous event. Choosing a settlement approach that offers simultaneous settlement — in which both legs of the trade move at the same time — eliminates most counterparty risk at settlement. In traditional settlement infrastructure, truly simultaneous movement is rare. Wires are sequential. Banks have cut-off times. One leg of a multi-party settlement can confirm hours before the other legs move, creating a window in which one party has paid and the other has not yet delivered.

## A concrete scenario: the commodity forward with split brokerage

Consider a physical commodity forward: a producer in Queensland agrees to sell 50,000 tonnes of coal at USD $148 per tonne (approximately AUD $231 per tonne at a current exchange rate both parties have pre-confirmed) to a buyer in South Korea, delivery in 90 days. The deal is arranged through two brokers — one representing the seller, one coordinating on the buyer side — and a settlement agent handles the cash leg.

**Day 1 — Reference price agreed.** The two brokers exchange a binding confirmation via email at 14:32 AEST, specifying USD $148/tonne, the volume, the delivery date, the calculation methodology (spot rate plus confirmed basis), and the identity of the settlement agent who will coordinate disbursement. Both parties sign digitally within the hour.

**Day 1 — Distribution schedule agreed.** The settlement agent circulates a distribution schedule, shown here on gross proceeds of USD $7,400,000 (50,000 tonnes at USD $148 per tonne).

| Payee | Share of gross proceeds | Amount |
| --- | --- | --- |
| Seller | 92% | USD $6,808,000 |
| Buy-side broker | 4% | USD $296,000 |
| Sell-side broker | 4% | USD $296,000 |
| **Total** | **100%** | **USD $7,400,000** |

All parties confirm in writing. The reference price and the distribution schedule now refer to each other by document number. Neither can be amended without the counter-signature of all parties.

**Days 2 through 89 — Price remains locked.** The market moves. Coal spot rates fluctuate significantly over the 90-day window. None of that matters to the locked trade. The reference price is USD $148/tonne. The distribution schedule is unchanged. The settlement agent holds the confirmed instructions and waits for delivery day.

**Day 90 — Settlement.** The buyer initiates payment of the full gross amount. Under a traditional wire-based settlement, this goes to the settlement agent's account first, who then initiates three separate outbound wires — one to the seller, one to each broker. Each wire has its own processing time, its own bank cut-off risk, and its own confirmation requirement. The seller may receive funds six to eight hours after the buyer has paid. The brokers may wait until the following business day. During that window, the settlement agent is holding someone else's money, the distribution has not actually occurred, and technically the deal is not closed.

This is the settlement gap in its most common form — not a failure of price negotiation or documentation, but a failure of the payment architecture to deliver what the confirmation promised: simultaneous, certain, final distribution to every party.

## What onchain routing changes about this picture

The payment routing layer is where the final step of any OTC settlement either works or creates friction. Getting the price right and the distribution schedule right is necessary but not sufficient if the actual movement of value takes hours, involves sequential wires, and cannot be verified by all parties in real time.

This is the specific problem that shaka.deal is built to solve. It is a non-custodial onchain payment router on Ethereum. When a single incoming payment hits a configured routing address, shaka.deal distributes it instantly to every party at preset shares — in one transaction, simultaneously, with finality. It routes; it does not hold funds. The split, the recipients, and the amounts are defined before the payment is initiated, matching exactly what the confirmed distribution schedule already specifies.

For the commodity forward scenario above, this changes Day 90 materially. Instead of the buyer wiring to the settlement agent who then initiates three sequential outbound wires, the buyer initiates a single payment to the routing address. In one transaction on the Ethereum network, the seller receives 92%, the buy-side broker receives 4%, and the sell-side broker receives 4% — simultaneously, in the same block. Onchain settlement replaces the multi-day, intermediary-heavy process of moving money and assets with a single blockchain transaction that transfers value and records final ownership at the same time.

The settlement agent's role is not eliminated or diminished — it is clarified. Instead of being responsible for sequentially disbursing funds and managing the risk that one wire fails while others succeed, the settlement agent is responsible for configuring the routing correctly before the payment is initiated. The professional expertise moves upstream, where it belongs: into the negotiation and documentation of the reference price and the distribution schedule. Execution becomes a verified, auditable event rather than a multi-step operational process.

Instead of a network of banks, clearinghouses, and custodians confirming a trade over days, the transaction records the change of ownership and completes payment in a single step. Once the block is finalized, the transfer is done, and no separate reconciliation is required to prove who owns what.

Onchain payments are also final in a way that wire transfers are not. On a proof-of-stake network like Ethereum, settlement finality is the point at which a blockchain transaction becomes irreversible. After finality, the payment cannot be reorganized out of history, double-spent, or unwound by a chain reorg. For a settlement agent or closing attorney, this means the confirmation of payment is also the confirmation of completion — there is no subsequent period during which the funds could be recalled, returned, or disputed at the network level. The certainty that professionals build into the pre-settlement documentation is matched by the certainty of the payment execution itself.

## A second scenario: multi-party advisory close

A business acquisition closing in Sydney: a buyer acquires a privately held logistics company for AUD $12.4 million (approximately USD $7.95 million). The deal involves a sell-side M&A advisor, a buy-side facilitating broker, a lender contributing partial funding, and legal counsel for each party. The settlement statement lists seven line-item payees. The closing attorney is responsible for ensuring every payee receives the correct amount at closing.

Under a traditional settlement workflow, the closing attorney collects funds from the buyer and the lender into a settlement account, then initiates outbound wires to all seven payees sequentially. If any wire is returned or delayed — a bank name mismatch, an account number transposition, a beneficiary bank cut-off time — the closing attorney must identify the failure, correct it, and re-initiate. Meanwhile, some payees have received funds and others have not. The deal is in a partially settled state that is uncomfortable for everyone and potentially exposes the attorney to liability.

With a routing configuration set up in advance through shaka.deal, the seven payees and their percentage shares are configured before the buyer initiates payment. When the single incoming payment arrives, all seven distributions execute in the same transaction. The closing attorney confirms the routing configuration against the executed settlement statement before payment is initiated — that is their professional contribution. Execution is then certain, simultaneous, and final.

The reference price was locked days earlier in the purchase agreement. The distribution schedule was confirmed the morning of closing. The payment routing address was configured to match that schedule exactly. The three elements are in alignment — and the settlement closes in one step.

## Practical checklist: locking price and settlement together

For any professional managing an OTC settlement or a multi-party commercial close, the following sequence reflects best practice across deal types.

<figure class="fig">
<figcaption><b>Locking price and settlement together</b><span>Six steps, in order</span></figcaption>
<ol class="steps">
<li><b>Confirm the reference price methodology before negotiating the number</b>Agree on whether you are using a VWAP, an exchange settlement print, a live OTC quote, or a fixed negotiated price — and document that agreement — before the specific rate is discussed. This eliminates a class of post-execution disputes where both parties agreed to "market rate" but disagree on which market and which timestamp.</li>
<li><b>Issue a binding written confirmation within the agreed validity window</b>A validity window should be indicated on every quote — for example, 30 minutes — meaning the client needs to decide whether to fix within that timeframe. The window protects the quoting party. A countersigned confirmation within the window converts a negotiating position into a locked obligation.</li>
<li><b>Circulate the distribution schedule simultaneously with the price confirmation</b>Do not allow the two documents to be separated in time. Every principal who has agreed to the reference price should confirm the distribution schedule before that confirmation is considered complete.</li>
<li><b>Cross-reference both documents by a shared identifier</b>Every amendment to either document — if an amendment becomes necessary — requires all parties' counter-signatures and creates an updated document version. The previous version is superseded and archived.</li>
<li><b>Configure payment routing before the settlement date</b>If the settlement uses an onchain router like shaka.deal, the routing configuration — recipients, addresses, percentage shares — should be set up and verified against the distribution schedule before the payment is initiated. The settlement professional's review of that configuration is the final control before execution.</li>
<li><b>Treat the routing confirmation as the last signature in the process</b>When the settlement agent verifies that the configured routing matches the executed distribution schedule, that verification should be documented the same way any other closing confirmation is documented. It is not a technical step — it is a professional certification that the distribution is correct.</li>
</ol>

## The underlying principle

Every technique described in this article serves one underlying principle: the reference price and the payment distribution are not two separate events connected by a gap in time. They are two expressions of the same agreement, and the gap between them is the source of all downstream risk — price drift, distribution disputes, failed wires, partial settlements, and the exposure that settlement professionals carry while funds are in motion.

The professionals who close OTC deals for a living have always understood this. They spend enormous effort drafting confirmations, negotiating settlement statements, and coordinating disbursement instructions precisely because they understand that the deal is not done when the price is agreed. The deal is done when every party has received exactly what the agreement specifies.

Settlement is the moment ownership legally and finally changes hands. Onchain settlement makes the blockchain ledger the authoritative record of that change, rather than a downstream copy of it. The tools available to settlement professionals in 2026 — including onchain routing through platforms like shaka.deal — make it possible for the execution of a distribution to be as certain and as well-documented as the confirmation that preceded it.

Lock the price. Lock the distribution. Execute once, simultaneously, with finality. That is the standard every professional in this space should be building toward.
