Market Context
The central bank’s 10 November 2026 rate table showed 24.5000 STN per euro on both sides. It quoted 21.8887 STN buying and 22.2170 STN selling per US dollar. The selling rates give a common basis for comparing EUR and USD card quotes against a dobra balance.
Compare two checkouts for the same crypto delivery
Suppose two checkouts deliver the same amount of crypto after any withdrawal charge. One bills US$100. The other bills €90. The central bank’s 10 November selling rates give benchmark debits of 2,221.70 STN and 2,205.00 STN, respectively. The euro quote starts 16.70 STN lower. Issuer charges or a different amount delivered could reverse that result.
At those rates, the break-even euro quote is approximately €90.68. Divide 2,221.70 by 24.50 to reproduce it. For the same asset, network and delivered quantity, the €90 option loses its benchmark advantage if it incurs more than 16.70 STN in extra charges relative to the dollar option. Use the final card debits for the actual comparison.
| Category | Value (STN) |
|---|---|
| US$50 | 16.42 |
| US$100 | 32.83 |
| US$250 | 82.08 |
The reference spread excludes card, crypto and bank charges.

Use the rate displayed in dobras per unit of foreign currency. The central bank’s homepage also shows values in a display scaled by 1,000. Reading 24,500 as the new-dobra price of one euro would overstate the benchmark by a factor of 1,000.
Price the sale separately
A card purchase can deliver crypto to a wallet or credit an exchange account. Neither outcome specifies where sale proceeds will go. To compare an exit, obtain the actual payout currency, destination and net credit for the same sale amount.
See São Tomé and Príncipe cryptocurrency regulation for the scope of the central-bank register. Finlazo reviewed public policies on 10 November 2026 and did not test a payment.
