Setting a daily limit for withdrawals is not uncommon in the USA and Canada--people who withdraw from ATMs here experience this for every transaction, as your bank at home has set a daily limit for you (with or perhaps without your knowledge). I checked with the Gobierno de México website, BBVA and Actinver reps and reps for both banks are pulling their hair out at the partial information, mistruths, and word of mouth errors. According to them, here's what the MTU means for us with bank accounts here in México:
• The MTU ONLY applies to México-to-México bank electronic transfers, with the intent of increasing consumer protection against online banking fraud. The daily transfer limit doesn't apply to ATM withdrawals, either from your Mexican account or from your NOB accounts. Also not impacted are Wise (or other transfer formats) from other countries to your account in Mexico, nor does it apply to a bank transfer you initiate from an institution outside México to a bank (yours or that of a third party) in México.
• Each bank has its own specific process for setting an MTU; you should be able to do this online within your account or, if you have trouble, see your bank advisor to show you the process.
• Setting of a daily limit can be changed by you--daily, or as often as you like, or as your needs change. (From Actinver today. Example 1: you want to purchase a car and transfer funds from your Mexican bank to the car dealership's Mexican account--you'll need to confirm/change your daily limit to cover your transfer, then reset. Example 2: If you go North for 6 months and have 6 months of rent to pay, CFE or other utilities to transfer to Mexican bank accounts, do the math, up your daily limit to cover the amounts and date(s) of your transfers, then reset and reset as needed.) The MTU is a total daily limit, not per transaction. So, if you have four bills to pay on Feb 1, add 1+ 2+3+4 and reset your limit for the total. Repeat each month or make a change as needed.
• If you don't set an initial daily limit for yourself, your bank will set one for you based on your account type and activity. There is not a "one size fits all of $12,500mx." You can make these changes yourself online or ask your bank advisor to walk you through the specifics for your banking institution.
