Exchange Rate (Bid Evaluation)

Exchange Rate (Bid Evaluation) refers to the official or specified currency conversion rate that a procuring entity fixes in the tender documents and uses to convert all bids denominated in foreign currencies into a single common evaluation currency, so that offers from suppliers in different countries can be compared on a consistent financial basis.

What is the Exchange Rate (Bid Evaluation)?

When a tender invites bids in multiple currencies -- for example, a local currency component and a foreign currency component -- or when international suppliers price in their home currencies, the evaluation committee cannot compare bid totals directly without first converting all amounts to a single reference currency. The tender documents specify a fixed exchange rate (or the source and reference date for determining the rate) to be applied to all bids during evaluation. The exchange rate used is typically the official rate published by the central bank of the borrower's country or an agreed interbank rate, fixed at a defined date close to the bid submission deadline.

This evaluation rate is used only for comparison purposes; the actual payment currency and exchange rate applicable at the time of payment are separate matters governed by the contract's currency-of-payment provisions. Bidders quoting in foreign currencies must understand that the procurement authority will convert their prices using the specified rate for evaluation, so a bid that looks competitive in the bidder's home currency may rank differently once converted. The method for setting the evaluation exchange rate is defined in the Instructions to Bidders section of the tender document, and bidders should verify it before pricing to avoid surprises during evaluation.

Why Exchange Rate (Bid Evaluation) matters for bidders

The fixed evaluation rate can create or destroy apparent competitiveness relative to local-currency bidders, and cannot be influenced once the deadline passes. Suppliers bidding in foreign currencies should model their bid price using the specified evaluation rate to understand how they compare against local bidders priced in the evaluation currency. Where the evaluation rate differs from the market rate at bid submission, the conversion will not reflect actual procurement cost, but the procuring entity is bound to use the specified rate regardless. Separately, suppliers must also consider exchange rate risk between bid submission and contract execution, since payment will occur at market rates prevailing during execution, which may differ materially from the evaluation rate used to select the winner.

FAQ

Where is the evaluation exchange rate specified in the tender documents?

The exchange rate, or the formula and reference date for determining it, is set out in the Instructions to Bidders, typically in the section covering bid currencies and bid price. Bidders should read this section carefully before pricing a multi-currency bid.

Is the evaluation exchange rate the same as the payment exchange rate?

No. The evaluation rate is fixed purely for the purpose of comparing bids. The rate applicable to actual payments under the contract is determined separately in the contract's currency and payment provisions, typically at the market rate prevailing at each payment date or at a rate specified in the Special Conditions of Contract.

What happens if a bidder uses the wrong exchange rate in their bid?

If a bidder's own currency conversion differs from the rate specified in the documents, the evaluation committee will apply the specified rate regardless. This can shift the bidder's apparent price ranking, so accurate modelling against the specified rate before submission is essential.
