French Bank Crédit Mutuel Arkéa Allegedly Hit by $133M Crypto Theft
Nov 4, 2026
On-chain investigator ZachXBT says French banking group Crédit Mutuel Arkéa is behind a mysterious crypto theft worth more than $133 million, adding to a rough stretch for the industry.
Another Big Name Gets Linked to a Crypto Heist
On-chain investigator ZachXBT dropped a bombshell on November 4, claiming the financial institution behind a crypto theft worth over $133 million is none other than Crédit Mutuel Arkéa, a major French banking group. If confirmed, this would be one of the bigger traditional-finance crypto losses we've seen this year.
Details are still thin, but ZachXBT has a strong track record of calling out hacks and tracing stolen funds long before official statements drop. The bank itself hasn't commented publicly yet, which is pretty standard while internal teams scramble to figure out exactly what happened.
Why It Matters
Banks dipping their toes into crypto custody or trading come with a new kind of exposure, and this story is a reminder that even legacy institutions aren't immune to the same security headaches that have plagued exchanges for years. Expect more details to trickle out over the coming days as on-chain detectives keep digging.
