Is there an ECB reference rate for crypto-assets?

No. The European Central Bank publishes reference rates for currencies, not for crypto-assets. There is no ECB rate for USDC.

Source: The ECB's own rate publications; for tax valuation, margin number 43 of the BMF letter of 06.03.2025 applies instead.

Context

The ECB rate is useful where an actual currency conversion happens. For a USD-pegged stablecoin the path has two steps: the crypto-asset's market rate per Rz. 43, then a USD to EUR conversion at the ECB reference rate. Both steps belong in the documentation.
