Since July 2024, the exchange rate between the Ethiopian birr and foreign currencies has been set through a market-based system. A central part of this system is the NBE's foreign exchange auction, where the central bank sells US dollars to commercial banks.
Understanding how these auctions work helps you make sense of rate movements and timing.
The Basic Mechanism
The NBE holds regular FX auctions on a scheduled basis. Commercial banks submit bids specifying how many dollars they want to buy and at what exchange rate. The NBE reviews the bids and allocates dollars based on the bids submitted.
The weighted average of accepted bids becomes the auction clearing rate. This rate serves as a reference point for the rates banks then offer to their customers.
Regular vs. Special Auctions
Regular auctions happen on a set schedule and involve smaller amounts. Special auctions are larger, one-off operations the NBE uses to inject significant liquidity into the market. In January 2026, the NBE conducted a record $500 million special auction. A second $500 million auction followed in February 2026.
Special auctions signal that the central bank has sufficient reserves and is willing to use them to support market stability.
What Happens After an Auction?
Once banks receive their dollar allocations, they use those funds to serve customer needs: import payments, remittance conversions, business transactions, and individual FX requests. The rate banks charge customers includes a spread on top of the auction rate to cover their costs and margin.
This is why the rate you see on BirrValue may differ slightly from the auction rate reported in the news.
Oversubscribed vs. Undersubscribed Auctions
When banks bid for more dollars than the NBE offers, the auction is oversubscribed. This has been common since the 2024 float, reflecting high demand.
When bids fall short of the amount offered, the auction is undersubscribed. The February 2026 auction was undersubscribed by about $45 million. This was notable because it suggested that dollar demand in the banking system was beginning to ease relative to supply.
Why This Matters for You
Auction results affect the rates you see at your bank within one to two days. After a large auction where banks receive generous allocations, rates may stabilize or even improve slightly. After a period without auctions or with limited supply, rates may drift higher.
If you are planning a large conversion or timing a remittance, it can help to know when auctions recently occurred. Rate changes often follow within 24 to 48 hours.
How to Use This Information
You do not need to track every auction in detail. Instead, use this general awareness:
- After major NBE auction announcements, check bank rates on BirrValue the next day.
- If rates have stabilized or improved, it may be a good time to convert or send.
- If rates are climbing and no auction is announced, consider waiting a few days if your timeline allows.
