Derived estimate — not a bank fact. Derived estimate - not a published figure. Croatia 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 Croatia 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 emerging peer group (Poland, Hungary and Spain) settles a median of about US$555,000 per capita per year; applied to Croatia's population and converted at € ~0.92/US$. This puts Croatia on the same wholesale-RTGS scale as the sourced tiles. A modelled input, not a recorded total.
