Derived estimate — not a bank fact. Derived estimate - not a published figure. Luxembourg settles euro payments through the Eurosystem's shared T2 system, which the ECB reports only in aggregate and for its five largest communities - no separate Luxembourg total is published, and the per-country figure sits only in the ECB Data Portal database. Estimated from the real RTGS throughput of comparable sourced countries: the advanced peer group (Germany, France, the Nordics and Czechia) settles a median of about US$1,540,000 per capita per year; applied to Luxembourg's population and converted at € ~0.92/US$. This puts Luxembourg on the same wholesale-RTGS scale as the sourced tiles. A modelled input, not a recorded total.
