CAF (Currency Adjustment Factor): FX Freight Risk and Contract Controls

CAF Is a Contract Formula

The SSDER glossary defines CAF as a currency adjustment factor used to protect shipping lines from currency movement. It is a pricing mechanism, not a blank cheque. The buyer should be able to reproduce the factor from the agreed source, date, base and scope.

A carrier may quote in one currency while paying port, feeder, rail or local costs in another. The contract should explain which exposure is being adjusted and which costs remain the carrier’s commercial risk.

Define the Currency Basis

Write the base currency, invoice currency, reference exchange rate, source, fixing date, conversion convention, rounding and effective period. If the shipment is booked before the rate is fixed, state which date controls and how a cancelled or rolled movement is treated.

Do not use an undefined “market rate.” A recognised central-bank, commercial or contractual source can work when the parties agree it and retain the observation. The calculation should show the base and adjusted amount.

Limit Scope and Avoid Double Recovery

CAF may apply to a defined base freight component but not automatically to taxes, storage, demurrage, a separate fuel factor or every accessorial. List included and excluded amounts, and check whether the carrier has already embedded FX risk in the base rate.

A route or supplier change may alter the exposure. Require a new approval when the currency, local-cost basket, carrier, mode or terminal changes rather than letting a historic CAF continue indefinitely.

Audit Index Moves and Invoices

The invoice should cite rate ID, CAF period, base amount, index values, formula, adjusted amount and currency. Procurement should compare the result with the contract and retain the source data used.

Track CAF variance, currency exposure, invoice disputes, unadjusted local costs, rate changes and the share of freight spend subject to indexation. Finance and procurement should review whether hedging, currency terms or sourcing changes would be more efficient.

Worked Example: A Factor Applied Twice

A carrier’s base rate includes a local terminal fee in euros. The carrier also applies CAF to the full invoice, including the same euro fee, and adds a separate “FX recovery” line. The buyer cannot reconcile the amount because the quote has no formula or scope.

The corrected contract applies CAF only to the agreed freight component, sets the reference source and caps the adjustment. The buyer rejects double recovery and measures the remaining exposure with finance.

Metrics and Governance

For CAF currency adjustment factor freight controls, measure both service and evidence quality. Useful indicators include first-pass acceptance, exception rate, response time, unplanned cost, document completeness, damage or discrepancy rate, and the percentage of shipments that follow the approved process. A dashboard should distinguish a supplier failure from a carrier, terminal, broker or internal master-data failure.

Review the metric trend with procurement, logistics, finance, quality and the responsible specialist. Use a monthly exception sample to test whether the control worked in a real transaction, not just whether a field was filled. Repeated exceptions should change the sourcing strategy, contract, lane design or supplier development plan.

Keep the control proportionate to risk. High-value, regulated, time-critical or safety-sensitive cargo needs stronger evidence and faster escalation than a routine shipment. Record the decision owner, approval date, source documents and follow-up action so the next buyer can understand the operating history.

Supplier and Carrier Questions

• Which CAF or related glossary condition is assumed in your quotation, procedure or service description?
• Which party owns each data field, physical handoff, inspection, document and exception?
• What evidence will be available before release, loading, movement, receipt, invoice approval or claim?
• What changes require advance notice, requalification, a revised price or a new risk decision?
• How will the supplier report incidents, delays, mismatches and corrective actions, and within what response time?

Implementation Sequence

Implement the control in a small, representative lane first. Capture the baseline process, test the required data and evidence, run a real transaction, and review every exception with the people who performed the work. Do not declare the control effective only because a supplier signed a procedure.

After the first three shipments or operating cycles, update the purchase-order clause, work instruction, scorecard and training. Scale the control to other suppliers only when the evidence is repeatable and the owner can explain what happens when the normal path fails.

Common Mistakes to Avoid

• Using CAF without a currency, index, date or formula.
• Applying the factor to charges already adjusted or indexed elsewhere.
• Allowing discretionary FX recovery beyond the agreed cost basket.
• Failing to cap, floor, notify or preserve the source exchange rate.
• Auditing the invoice without checking the base rate and local-cost scope.

Procurement Implementation Checklist

• Define base and invoice currencies and the reference exchange source.
• Set fixing date, effective period, formula, rounding and evidence.
• List the cost components included and excluded from CAF.
• Set notice, cap, floor, change and dispute procedures.
• Reconcile rate ID, index values, base and adjusted invoice amount.
• Review FX exposure, double recovery and alternative currency options.
