Getting the best exchange rate is about knowing where to look and what to avoid. Here is a practical guide.
Avoid airport exchange booths
Airport counters typically offer the worst rates, with spreads of 5-10% or more above the market rate. Only exchange a small amount for immediate needs.
Use ATMs wisely
Mexican ATMs on the PLUS or Cirrus networks often offer rates close to the interbank rate. Always choose to be charged in pesos, not in your home currency, to avoid Dynamic Currency Conversion fees.
Compare banks and exchange houses
Institutions differ dramatically. Mexican banks routinely run spreads above one peso, while online casas de cambio are far more competitive. The table on our homepage compares them side by side, updated through the day.
Use an online exchange service
Services like Tkambio offer near-market rates for transfers between the US and Mexico, regularly beating traditional banks by 2-4%.
Timing matters
The FX market is most liquid during business hours Monday to Friday. Rates tend to be more favourable mid-week, when volatility is lower.
Pro tips
- Always ask for the total amount you will receive, not just the rate
- Never exchange with street vendors — security and rate risk
