Where money leaks
FX markups on debit/credit cards, dynamic currency conversion at foreign terminals (always pay in local currency!), ATM fees abroad, paper statement fees and dormancy charges. None appear as a line item called 'fee' – they hide in exchange rates.
The fix
Hold one card with ~0% FX markup for foreign/online spending; keep your main banking wherever it serves you. Check the exchange rate your bank applied against the mid-market rate once – the gap is your real fee.
Audit yearly
One yearly fee audit (account, cards, FX) per household – ten minutes, typically CHF 100–300 found.
