Special Drawing Rights (SDR) Conversion

Special Drawing Rights (SDR) are an international reserve asset created by the International Monetary Fund (IMF). They do not circulate as a currency, but serve as a unit of account based on a weighted basket of five major world currencies: the US dollar, the euro, the Chinese renminbi, the Japanese yen, and the British pound sterling. The World Trade Organization Government Procurement Agreement (GPA) uses SDR as its threshold unit of account precisely because no single national currency can serve as a neutral benchmark for an international agreement.

What is Special Drawing Rights (SDR) conversion?

The GPA sets its procurement threshold obligations in SDR. For example, the GPA establishes that central government entities must follow open international procurement procedures above a threshold of 130,000 SDR for supplies and services. To give this figure practical effect within EU law, the European Commission must translate the SDR amount into euros.

The Commission does this through a formal calculation process:

1. It calculates the average EUR/SDR exchange rate over a 24-month reference period preceding each biennial review.
2. It applies that average rate to the SDR threshold values agreed under the GPA.
3. It rounds the resulting euro amounts to the nearest 1,000 euros to produce clean, workable figures.
4. It publishes the resulting euro thresholds in the Official Journal of the European Union via a dedicated Commission Regulation.

The new thresholds take effect on 1 January of the relevant year and remain in force for two years until the next threshold review period (biennial).

Because the SDR is itself a basket of five currencies, its value relative to the euro reflects movements in the dollar, yen, renminbi, and pound as much as the euro itself. In periods where the euro weakens against the broader SDR basket, the euro-equivalent threshold rises (more contracts fall below full-procedure requirements in SDR terms). When the euro strengthens, the opposite occurs.

Why it matters for bidders

SDR conversion explains why EU procurement thresholds change every two years and why the changes are sometimes surprising (a rise in one period, a small fall in another). Understanding the SDR mechanism prevents confusion when thresholds shift: it is not a policy change but an arithmetic recalibration.

For multinational suppliers bidding across Europe, it is also worth noting that the UK operates its own threshold system under the Procurement Act 2023, and UK procurement thresholds are similarly derived from GPA SDR values, but converted into British pounds sterling rather than euros, using a separate GBP/SDR rate calculation conducted by the UK government.

Example

Suppose the EUR/SDR exchange rate averaged 1.18 EUR per SDR over the 24-month reference period before a biennial review. The GPA central government services threshold is 130,000 SDR. Multiplying: 130,000 x 1.18 = 153,400 euros. Rounded to the nearest 1,000 euros, this produces a published threshold of 153,000 euros. If in the following period the euro strengthens and the average rate falls to 1.10 EUR per SDR: 130,000 x 1.10 = 143,000 euros, producing the lower threshold observed in recent review cycles.

Frequently Asked Questions

Can countries outside the EU use the same SDR conversion for their thresholds?

GPA parties that are not EU member states (such as the United States, Japan, Canada, South Korea, and others) apply the same SDR threshold values under the GPA but convert them into their own national currencies. Each country or bloc publishes its own converted thresholds. The SDR is a common yardstick; the currency conversion produces different national threshold figures.

Is the SDR basket changed frequently?

The IMF reviews the composition of the SDR basket every five years. The current basket (US dollar, euro, renminbi, yen, pound) took effect in October 2016. Changes to the basket composition could shift SDR values relative to the euro, affecting future biennial threshold calculations. Such changes are relatively infrequent and are signalled well in advance.

Does the SDR mechanism affect below-threshold procurement?

Not directly. The SDR conversion determines the threshold values above which full EU directive procedures apply. Below those thresholds, national rules govern procurement, and there is no SDR calculation involved in their application. However, if national rules are themselves aligned to EU directive thresholds (as they often are in practice), the biennial SDR adjustment can have a knock-on effect on nationally-set subnational thresholds.
