For the really large banks: $XYYMM (i.e. hundreds of million dollars aka the cost of doing business) across all lines of business. All this is mostly public info as it has to go into financials, you can find it under "Operational Losses" for any public bank (Note that "Operational Losses" are not the same as "Operating Losses"). A sample multi-year summary can be found here from an industry body in Europe for losses for debit. (losses are demonimated in Euro):look at page 7 under the last column for the rows "Retail Banking". Important to note that credit ops losses are an order (or maybe two) of maginitude higher. https://managingrisktogether.orx.org/sites/default/files/downloads/2018/09/annualbankinglossreport2018-printversion.pdf https://managingrisktogether.orx.org/sites/default/files/dow...
