Executive answer
Foreign-exchange risk does not automatically belong to the entity reporting the accounting gain or loss. Transfer pricing asks who decided to denominate revenue, purchases or debt in a currency; who can accept, avoid or mitigate exposure; who executes and monitors hedges; and who has the financial capacity to bear the outcome.
A global policy may centralize decisions, leave execution locally, or divide responsibilities. The intercompany agreement can allocate risk, but conduct must confirm it. If Mexico only records a dollar invoice determined by the parent, without authority to change currency or hedge, the contractual label needs testing. If the Mexican team negotiates prices, forecasts and derivatives within limits, its control may be greater.
The correct analysis does not move every loss to a profitable entity. It delineates commercial, financial and hedging transactions, values treasury functions and allocates outcomes according to decisions, capacity and contemporaneous evidence.

Complete the map for each flow. “Global treasury” is neither a person nor evidence.
Identify exposure
Separate transaction, translation and economic exposure. Transaction exposure arises from monetary items denominated in another currency: sales, purchases, royalties, services, loans or balances. Translation exposure arises from converting financial statements. Economic exposure reflects how currency movements change demand, price or competitiveness. They do not all require the same treatment or create a controlled transaction.
Build an inventory by currency and maturity showing notional amount, date, counterparty, relationship, account, underlying flow and pricing mechanism. Distinguish gross and net exposure. A dollar receivable may economically offset a dollar purchase only when amount and timing are compatible.
Identify exposure created by intercompany policy: long payment terms, late true-ups, group-currency invoicing or a multi-currency cash pool. A margin deviation may be partly FX and partly pricing. Keep a bridge.
Delineate risk control
Control means real capacity to decide whether to assume or decline risk and how to respond. Ask who has information, competence, authority and process. Signing a bank confirmation is not enough when another entity defined strategy; approving a manual is not enough if the local team decides material exceptions.
Interview responsible people and test three actual events: a currency shock, a limit breach and a failed hedge. Who detected, escalated and decided? Compare answers with policy and emails. Events reveal conduct more reliably than an organization chart.
Financial capacity also matters. The assigned entity should be able to bear reasonable scenarios without relying on automatic rescue inconsistent with the supposed allocation. Model volatility, concentration and liquidity; positive equity is not unlimited capacity.
When control and capacity sit in different entities, analyze the consequence under the applicable framework. An entity that only supplies funding without controlling risk may not earn the entire risk return.
Currency of operating contracts
Review why sales and purchases use each currency. Compare functional currency, market practice, customer, supplier, competition and alternatives. A Mexican distributor selling in pesos and buying in dollars may bear exposure when it controls local pricing and inventory; it may also have pass-through clauses or bands.
Document adjustment clauses, frequency, lag and caps. The ability to pass through FX does not eliminate all exposure because volume and timing can change. A target-margin policy should state whether its indicator is measured before or after FX and which component is adjusted.
Do not retrospectively label losses “extraordinary” without a pre-existing criterion. Define treatment in policy and monitor gains and losses symmetrically.
Financing currency
Debt currency should align with cash flows available for service unless a documented rationale supports another choice. Compare currency of revenue, costs, dividends and assets. Model natural hedges and derivative needs. Cheap foreign-currency debt may be costly after risk.
The interest benchmark should use the same currency and date or reliable adjustments. Do not offset a low rate against FX exposure without analyzing each component. Test whether an independent borrower would choose another currency or require covenants.
If the group centrally converts or hedges, delineate whether Mexico receives a loan, derivative, treasury service or combination. Each component needs its own pricing and documentation.
Hedges and central treasury
Classify external hedges, back-to-back arrangements, internal netting or execution mandates. Identify instrument, notional, term, underlying, counterparty and economic effectiveness. Hedge accounting is evidence but does not itself determine transfer pricing.
A central treasury may provide routine execution, confirmation and reporting or make broader risk decisions. Price functions according to assets and risks controlled. Do not give every saving to central treasury when participant positions create it; do not leave all benefit in Mexico when central treasury negotiates and assumes bank exposure.
Internal spreads require comparison with alternatives. If central treasury enters an external derivative and mirrors terms, analyze cost, margin, credit and functions. Where it nets multiple entities, define allocation of synergy and costs.
Zugzwang’s Treasury Risk Review connects commercial contracts, debt, derivatives, decision makers and outcomes to explain who controls risk and which remuneration follows.
A defensible treasury policy
The policy should define objective, perimeter, currencies, exposure types, appetite, limits, permitted instruments, counterparties, approvals, segregation, testing and reporting. Include exception treatment and escalation. A policy that merely says “reduce volatility” does not allocate decisions.
Add a transfer-pricing schedule covering functions by entity, ownership of contracts, service charges, benefit and loss allocation, intercompany balances and rebalancing events. Align it with service, loan and cash-pool agreements.
Review at least annually and after a material business change. Control versions because the policy in force during the event is relevant.
Measure outcomes
Produce a bridge of realized and unrealized results by flow, currency, transaction and instrument. Separate FX from principal, interest, fee, purchase or sale. Reconcile bank, treasury system, subledger and general ledger. Explain rate and date differences.
Measure performance against the approved objective, not a perfect hindsight outcome. A hedge can lose value while offsetting the underlying. Evaluate the combined position. A favorable result does not prove control, and a loss does not prove its absence.
For a limited-risk entity, define whether the benchmark includes FX and how exposure outside its control is handled. Do not automatically guarantee a margin when the entity makes real currency decisions. Policy, FAR and conduct must align.
Illustrative case
Mexico buys inventory in dollars, sells 80% in pesos and reports to a European parent. The agreement calls it a limited-risk distributor. The parent sets the purchase list, but Mexico decides discounts and inventory and may enter forwards within a limit. Central treasury consolidates forecasts and executes with the bank.
The analysis separates commercial pricing risk, purchase exposure, local forecast and hedge decisions, central execution and bank credit. It tests whether the treasury charge compensates routine execution or additional control. Gains and losses are allocated from the facts, not solely from the distributor label.
If Mexico breaches a limit by failing to update its forecast, document who decided and what consequence independent parties would accept. Do not automatically move the cost to central treasury.
Operating controls
Reconcile material positions daily or weekly. Compare exposure with limits and report exceptions monthly. Test forecast accuracy, agreement currency and internal charges quarterly. Update FAR, capacity and service or spread benchmarks annually.
Segregate dealing, confirmation, settlement and recording. Control access, bank limits and independent confirmations. A control weakness can undermine evidence even where the economic policy is reasonable.
Maintain a log showing event, amount, owner, decision, approval, result and remediation. The committee should see exceptions, not only the net position.
Audit questions
- Which transaction created exposure?
- Who chose currency and term?
- Who could avoid or hedge it?
- Who set the limit and approved exceptions?
- Did the entity have financial capacity?
- Which function did central treasury perform?
- How was any charge or spread priced?
- Are gains and losses treated symmetrically?
- Do agreements, policy and conduct align?
- Does the result reconcile to accounting and returns?
Each answer should point to dated evidence. A memorandum written after year-end does not replace contemporaneous minutes, tickets and reports.
Minimum file
Retain the policy, authority matrix, exposure inventory, underlying contracts, loans, derivatives, forecasts, limits, approvals, tickets, confirmations, bank statements, reports, effectiveness tests, reconciliations, FAR, service-charge computation and capacity analysis.
Include a chronology of material events and an explanation of Mexican tax treatment for interest, FX and instruments based on the facts. Classification under one provision should not be extrapolated to another without analysis.
Forecast governance and adjustments
The forecast is an economic decision when it determines hedge volume. Define horizon, granularity, tolerance and owner for every flow. Compare forecast with actual weekly or monthly and classify variance: volume, price, date, currency, missing invoice or business change. An aggregate accuracy metric may hide that one entity consistently overstates receipts while another understates purchases.
Do not penalize every inaccuracy automatically. Determine which information was available and which standard an independent treasury would apply. Repeated variance without remediation may nevertheless show that the supposed risk controller is not exercising effective control. Record actions, training, system changes and approval of tolerances.
Transfer-pricing adjustments can create exposure after year-end. If a true-up is invoiced in dollars in March for the prior year, document who controls currency and the FX period between measurement, invoicing and payment. The policy should say whether the target margin includes that movement and prevent the mechanism from changing only when the outcome is unfavorable.
Counterparties and credit risk
A hedge creates exposure to the bank or central entity. Document counterparty limits, collateral, netting, margin calls and replacement rights. If Mexico does not sign the external derivative but assumes an internal contract, compare credit quality and rights under both. A back-to-back price may need adjustments for credit, capital, liquidity or execution.
Where several entities contribute positions, explain who receives the netting advantage and bears an imbalance. Apply a consistent rule based on notional, usage or marginal contribution and test sensitivity. Do not allocate currency savings by revenue when positions produced the benefit.
Decisions under exceptions
Use a simple decision tree: identify exposure; test the limit; decide to hedge, accept or correct; obtain approval; execute; confirm; measure; close the exception. Each exit needs a threshold and deadline. A position can remain open when cost and risk justify it, but the decision should be prospective and attributable.
During severe events, retain available quotes, market liquidity, restrictions and communications. Hindsight should not turn a reasonable decision into an error merely because the market moved. It should equally not excuse inaction where limits and alerts were ignored.
Interaction with intercompany accounts
Trade balances can become financing when payment behavior departs from ordinary terms. Track aging, disputed invoices and recurring extensions. Determine whether the currency exposure belongs to the underlying sale or a separate funding period. An independent seller might change price, charge interest, demand collateral or shorten terms.
True-ups, royalties and service charges should enter the exposure inventory before invoicing when reliably measurable. Otherwise central treasury cannot make an informed hedge decision. Align tax, accounting and treasury calendars and document which rate is used for accrual, invoice, settlement and return reporting.
