Some of the top receiving countries include France, Germany or Belgium (over $1000 per inhabitant) and the top sending countries include Luxembourg ($12B for a population of 575K).
So the numbers probably include cross-border workers. People living in France/Germany/Belgium but working in Luxembourg. Transferring euros within the SEPA region (for free) for at least $50B out of the $560B mentioned.
That strikes me as an appealing use case.
