Bottom line: Cuba has 3 currencies in use 2026: MN (official Cuban peso, ~24 MN/USD official but ~280 MN/USD informal), MLC (Freely Convertible Currency, USD-equivalent for state stores with pre-loaded MLC card), and USD/EUR/MXN cash (accepted informally everywhere tourist-related). MEXICAN CREDIT AND DEBIT CARDS DON’T WORK in Cuba — blocked by US sanctions. Bring $US 600-800 cash for 4-7 days Havana. Exchange gradually at CADECA or via casa particular host.

The 3 currencies in Cuba {#currencies}

1. MN (Moneda Nacional, Cuban peso CUP)

Local official Cuban currency
Used for: public transport, bread, local market, local hairdresser, food at casa particular
Official rate May 2026: ~24 MN per USD
Real informal rate (black market or gray CADECA): ~280 MN per USD

2. MLC (Moneda Libremente Convertible)

Virtual Cuban currency at USD parity (1 MLC = 1 USD officially)
Used for: purchases in state stores “MLC” — supermarkets accepting international cards (rare) or pre-loaded MLC cards
For Mexican tourist: almost never relevant

3. USD / EUR / MXN cash

Accepted informally at hotels, tourist restaurants, tourist taxis, casas particulares
USD is preferred (most), EUR second, MXN at worst rate

The big trap: Mexican credit cards

MEXICAN CREDIT AND DEBIT CARDS DON’T WORK IN CUBA.

Why? Most chains (Visa, Mastercard) blocked by US sanctions. Few cards working:

Cards issued in non-sanctioned countries (Canada, Europe, Asia) — limited utility
Pre-loaded MLC cards in Cuba (not useful for tourist)

Consequence: bring ALL cash USD or EUR. Calculate your budget well before trip.

How much cash to bring (4 days Havana recommendation)

Concept	Cost
Casa particular ~$US 25-40/night × 4	$US 100-160
Food (tourist restaurants + paladares ~$US 25-40/day)	$US 100-160
Taxi airport + city taxi	$US 50-80
Excursions (Viñales, Trinidad, Cigar tour)	$US 60-150
Shopping (cigars, rum, souvenirs)	$US 50-100
Unforeseen reserve	$US 50-100
TOTAL 4 days	$US 410-750

Bring $US 600-800 cash for 4 days Havana. Mix bills ($20 + $50 + $10 + some $1 for tips).

Cash safety tips

Bring USD post-2009 (Cuba prefers); pre-2009 some changers reject
Damaged/marked USD bills: rejected
Don’t carry all together — separate in 2-3 pockets/places
Anti-theft belt under clothing for majority of money
Small cangurero with $US 100-200 for “daily use”
Hotel safe for the rest
DON’T declare funds if carrying < $US 10,000 (Banxico limit) — > $US 10,000 declare obligatory in FinCEN 105 at exit/return Mexico

Why Mexican cards DON’T work {#cards}

The US sanctions blockade

USA maintains economic sanctions against Cuba since 1962 (Helms-Burton Embargo). Visa, Mastercard, American Express have main servers in USA. This means:

Visa MX (Banamex, Santander MX, BBVA MX): doesn’t work in Cuba
MasterCard MX: doesn’t work
American Express MX: doesn’t work (also blocked by OFAC)
AmEx International: doesn’t work in Cuba
Apple Pay / Google Pay: doesn’t work

Few cards that DO work in Cuba

Cards issued in Canada, Europe, Asia, Australia — some work (Mastercard international with non-US BIN)
MLC cards pre-loaded in Cuba — yes work (government system for residents)
Visa/MC issued in Europe by non-US banks (HSBC UK, Santander Spain, BBVA Spain, BNP Paribas) — yes work, 2-4% commission

Implication for Mexican

CAN’T withdraw money in Cuban ATM with your Mexican card — rejection error
CAN’T pay hotel with Mexican card — rejection error
MUST carry EVERYTHING in cash — no alternative
If you run out of cash in Cuba = real problems

Advanced strategy (experienced paisanos)

Some paisanos get non-US international cards before traveling:

HSBC Spain account (requires opening account in Spain — complicated for non-resident)
Eurozone prepaid card via Revolut/Wise EU (some work partially)
Note: these options are experimental — verify with card issuer customer service before traveling

For 99% Mexicans: bring USD cash, problem solved.

How much cash to bring (4-7 days) {#cash}

Vacation 4 days Havana (classic Havana)

Total estimate: $US 600-700 (covers casa particular, paladars, taxi, 1 excursion, shopping, reserve).

Vacation 7 days Havana + Viñales + Trinidad

Total: $US 1,200-1,400 (additional days + extra excursions).

Cash tips

Mix bills: $50 + $20 + $10 + $5 + some $1 — useful for taxis and tips
DON’T carry all together — separate in 2-3 pockets/places
Anti-theft belt under clothing for most money
Small cangurero with $US 100-200 for “daily use”
Hotel safe for the rest (almost all 3★+ hotels have safe)

Where to exchange and at what rate {#exchange}

CADECA (official Cuban exchange) — bad deal

At Havana airport (HAV): open 24/7
In Havana Vieja Plaza Vieja, Plaza de Armas
In 4-5★ hotels
Official CADECA rate May 2026: ~24 MN/USD (terrible)
Only recommended if you need very little ($US 20-40) for public transport

Casa particular hosts — real informal rate ✅

Your casa particular host usually exchanges at real informal rate (~280 MN/USD May 2026)
This is common practice known by everyone
Illegal technically but not pursued by Cuban authorities
Rate they give: 260-280 MN/USD (vs. 24 official)

Recommended change: $US 50 to host = ~14,000 MN for daily use.

Informal market (street changers) — risk

In Havana Vieja Plaza Vieja, “money changers” approach offering rate
WATCH: many scams — fake bills, count manipulation
If you decide: count money before handing over USD and verify bills are legitimate
NOT recommended for first-time tourist

Your casa particular is always best

Real informal rate
No scam risk (it’s your host, you know where they live)
Convenience (exchange when you want)

FAQs {#faq}

Can I use Bitcoin or other crypto in Cuba?

Limitedly. Some paladars and tourist shops accept USDT (Tether) via digital wallet, but NOT mainstream. Cuban telecom is unstable (ETECSA monopoly, expensive internet), making crypto transactions difficult. For tourist: cash better.

How much USD can I bring to Cuba without declaring?

To Cuba (entry): up to $US 5,000 without declaring. >$5,000 declare with form at José Martí airport. To Mexico (return): up to $US 10,000 without declaring (Banxico).

Does Cuban government monitor my informal currency exchange?

Technically yes, but in practice doesn’t pursue tourists. Pursues Cubans systematically exchanging as business. A tourist exchanging $US 100 at casa particular = no problem.

Do I need to tip in MN or USD?

Either works. Common for tourists: tips in USD/EUR (easier for Cuban staff to use — they can exchange at best rate). $US 1-2 per tourist service, $US 5-10 for excellent paladar.

Are there international ATMs (Plus, Cirrus) in Cuba?

ATMs exist, but blocked for US-issued cards (including MX). Only work with non-US international cards (EU, Asia).

Does my Aeromexico Premier credit card work in Cuba?

NO. Aeromexico Premier is Visa or Mastercard issued by Mexican bank (Santander US Premier Mastercard or BBVA Aeromexico) — blocked in Cuba.

What if I run out of cash in Cuba?

Limited options:

Western Union: closed in Cuba 2020, not available 2026
Urgent family transfer: your family in Mexico sends with special Cuban remittance (operators like “Cuba SoyDelivery” or “Ezimerchant”) — slow, $50-100 commission
Exchange belongings with other tourists — not recommended
Mexican Embassy in Cuba: only emergency
Return to Mexico early and bring more: if flight flexible

Does the real informal rate rise or fall?

The MN/USD informal rate has risen consistently since 2020:

2020: ~50 MN/USD
2022: ~120 MN/USD
2024: ~220 MN/USD
2026: ~280 MN/USD

Cuban inflation strong. Your USD is worth more each year.

Do Diners Club, JCB, other cards work?

Better than US Visa/MC, but variable. Don’t be sure of anything — always bring cash.
