## Official vs. informal rates by country

### Argentina — 30-40% difference

| Concept | Rate | For Mexican |
|---|---|---|
| Official (Banco Nación) | ARS $1,200/USD | Foreign card gives this (bad) |
| Tourist card with charges | ARS $1,400/USD | Foreign card with +30% PAIS tax |
| **Blue (informal cueva)** | **ARS $1,500-1,700/USD** | **YOUR best option** ✅ |
| MEP (via bonds) | ARS $1,650-1,750/USD | Investors |

**Mexican tourist difference:** between official and blue = ~40% more purchasing power. [See blue rate guide](/en/buenos-aires-usd-mexicano-blue-rate-cuanto-llevar/)

### Cuba — 12× difference (1,200%)

| Concept | Rate | For Mexican |
|---|---|---|
| Official (airport CADECA) | CUP $24/USD | Terrible deal |
| Informal (casa particular host) | CUP $260-280/USD | YOUR real option ✅ |
| MLC virtual | 1 MLC = 1 USD | For Cuban residents |

**Difference:** ~12× more Cuban pesos with informal rate. [See Cuba currency guide](/en/cuba-moneda-mn-mlc-usd-cambio-aeropuerto-habana/)

### Colombia — small difference

| Concept | Rate | For Mexican |
|---|---|---|
| Official (Bank) | COP $3,300/USD | OK |
| Cuevas (Bogotá, Cartagena) | COP $3,350-3,400/USD | Marginally better |
| MX card at Colombia ATM | COP $3,250/USD (with 3-5% commission) | Mediocre |

**Tip:** In Colombia, **withdraw COP at ATM with Mexican card** = good deal. Difference vs. cuevas ~2-3%.

### Chile — single rate, no parallel market

| Concept | Rate |
|---|---|
| Official (all exchange houses) | CLP $905/USD |

Chile has no significant informal market. Unit rate.

### Peru — small informal advantage

| Concept | Rate |
|---|---|
| Official | PEN $3.75/USD |
| Lima street changers | PEN $3.80/USD |

Minimal advantage. Use card for most.

### USA / Eurozone / UK — official only

USD, EUR, GBP have no parallel markets. Single rate. **Exchange at Mexican bank before traveling** or **use card** for convenience.

## Why airport exchange is bad deal

### Airports where you shouldn't exchange

**Official exchanges at airports:**
- AICM (CDMX) → Banamex/Santander official exchange: 2-4% worse than online
- GDL → similar
- MTY → similar
- International airports: 4-8% commission worse than local options

### Why you lose

1. **Operator margin** (3-5%)
2. **Additional commission** (2-4%)
3. **Airport rent** passed to you
4. **Buyers in hurry** = captured market

### When you SHOULD exchange at airport

- **Only USD $50-80** for emergency (taxi, food on arrival)
- In airports in countries with no local alternative (not Mexico)

### Best alternative per destination country

| Destination | Best option |
|---|---|
| **USA, UK, Eurozone** | Exchange at Mexican bank before traveling OR use Mexican credit card (1-3% better commission) |
| **Argentina** | USD cash + cueva in Buenos Aires (blue rate) |
| **Cuba** | USD cash + exchange with casa particular host |
| **Colombia** | Mexican card at Colombia ATM (3-5% commission) |
| **Chile, Peru, Brazil** | Mexican card at local ATM |

## Best strategy per destination

### Strategy A: USD cash + local exchange houses

**For:** Argentina, Cuba

- Bring $US 1,500-3,000 cash
- Exchange gradually at cuevas/casa particular
- Benefit: blue rate / casa-particular rate

### Strategy B: Mexican credit card + local ATM

**For:** Colombia, Chile, Peru, Brazil

- Banamex/Santander have 3-5% commissions at international ATM
- BBVA Mexico "Tarjeta Negocios" has reduced 2% commission
- Mexican American Express Platinum: no international ATM commission (best option)

### Strategy C: Exchange at Mexican bank before traveling

**For:** USA, UK, Eurozone, Japan

- Buy USD/EUR at Mexican bank (Banamex, Santander) with anticipated order
- Commission: 1.5-3%
- Better than airport exchange

### Strategy D: Western Union for emergency

**For:** Any destination emergency

- Your family sends MXN in MX → you receive local currency at destination
- Commission: 5-12%
- Exchange rate: close to official

### Strategy E: USDT crypto (advanced)

**For:** Argentina, Brazil

- Buy USDT (Tether) on Bitso Mexico with MXN
- Sell USDT at destination via Binance P2P
- Exchange rate: close to blue
- **Only for crypto-experienced users**
