By business: • In Retail , net fee income increased 8%, supported by mutual funds, foreign exchange and insurance fees. • In Consumer , net fee income fell 6%, despite strong growth in the US (auto servicing fees), mainly due to DCB Europe, which was impacted by new insurance regulation in Germany and the drop in new car registrations in the EU. • In CIB , it increased 9%, driven by the three main business lines, but especially Global Transaction Banking (GTB) and Global Banking (GB) in the US, boosted by our US Banking Build-Out (US BBO) initiative. • In Wealth , net fee income rose 20%, with good growth in Private Banking and Asset Management due to good commercial dynamics in Spain, Latin America and the US. • In Payments , net fee income rose 15% boosted by both PagoNxt and Cards driven by higher activity across countries. This positive net fee income performance keeps us on track to achieve our mid-high single digit growth target for 2025.
