This information was given to me, as the Moderator, from a very reliable source close to the industry who requests to remain anonymous:
This is not what happened. SPEI is the company that is used to make inter bank transfers. That system was hacked. Anyone who lost money was or will be reimbursed via the equivalent of FDIC insurance. Banks that were affected were Banamex, Bancomer, and Banorte. The information regarding banks that do not participate in the SPEI program is false. All Mexican banks use the SPEI as it is recommended by Banxico the national banking system.
Really appreciate all of you getting the information out there.
