New US Dollar Exchange Regulations
In the past travelers to Mexico could use US dollars for most transactions, and many people didn't even bother to exchange their currency into pesos. With new laws in effect since September 2010, however, the use of US dollars in cash for making purchases is limited, and the sums exchanged at banks and currency exchange booths are restricted. These measures have been brought into effect to combat money laundering and organized crime, unfortunately tourists and legitimate businesses are also affected.

Official Statement:

"Mexico Banking System Cap on Exchange of Dollars for Pesos:
In order to regulate the quantity of dollars entering the Mexican banking system, beginning September 14, 2010, the Mexican government will cap the amount of dollars foreigners can exchange for pesos in Banks & Money Exchange Establishments to no more than US$1,500 per month.

The measure WILL NOT AFFECT purchases made with credit cards or debit cards in Mexico.

The measure WILL NOT AFFECT the amount of cash (in Mexican pesos) an international tourist can withdraw from an ATM machine on a daily or monthly basis.

It is recommended that all travelers bring Mexican pesos as well as their credit and/or debit cards to minimize any inconvenience the exchange cap at banks may cause."

Exchanging Dollars for Pesos
According to the new regulations, casas de cambio (currency exchange booths), banks and hotels may exchange a maximum of $1500 USD in cash per person per month into Mexican pesos. Many financial institutions are limiting this to exchange up to $300 USD in a single transaction, and some banks are currently refusing to exchange dollars. It may also be required to present an official identification when exchanging dollars for pesos.

Purchases Goods and Services
Businesses may accept a maximum of $100 USD in cash per transaction, with no restriction on the number of transactions per customer. However, many businesses are choosing to not accept US dollars at all. Likewise, many airlines within Mexico will only accept Mexican pesos and credit cards for payment of fees (such as baggage fees). The most convenient way to pay for purchases is to use a credit card or withdraw Mexican pesos from an ATM. It is not advisable to carry large amounts of cash.

Other Currencies Not Affected
It is important to note that these new regulations regarding currency exchange do not apply to other foreign currencies such as Euros and Canadian dollars, and forms of payment other than cash, such as credit cards and travelers checks, are not affected by these measures.


  • If possible, exchange a small amount of currency to Mexican pesos before your departure. Take enough pesos to cover your expenses on arrival (tips to baggage handlers, taxi, etc.)
  • Pay with a credit card when possible.
  • Take a credit card or debit card for ATM cash withdrawals.
