If you traveled to Havana anytime between the mid-nineties and 2020, you probably remember the colorful, slightly plasticky bills that felt more like Monopoly money than a national currency. That was the Cuban convertible peso CUC. Most of us just called them "chavitos" or "kooks." Honestly, it was a bizarre system. You’d land at José Martí International Airport, head to a CADECA (the state-run exchange house), and trade your Euros or Dollars for these specific notes that were only meant for tourists and luxury goods.
But if you go back today? Those bills are essentially expensive wallpaper.
The Cuban convertible peso CUC is dead. On January 1, 2021, the Cuban government pulled the plug on one of the most confusing monetary experiments in modern history. They called it "Day Zero." It was the start of a massive "monetary reordering" that was supposed to fix the economy but, in many ways, just swapped one set of headaches for another.
Why the CUC Existed in the First Place
To understand why Cuba had two currencies, you have to look back at the "Special Period" in the early 90s. The Soviet Union had just collapsed. Cuba lost its biggest benefactor overnight. Suddenly, there was no fuel, no food, and definitely no hard currency.
Fidel Castro’s government had to do something drastic. They legalized the U.S. Dollar in 1993 to attract foreign cash. It worked, but it was embarrassing for a socialist revolution to rely on the "currency of the enemy." So, in 1994, they introduced the Cuban convertible peso CUC.
The Original Goal
The idea was basically to capture foreign exchange. The government pegged the CUC 1:1 with the U.S. Dollar.
- The CUP (Cuban Peso): Used by locals for state salaries, utility bills, and rationed goods.
- The CUC (Convertible Peso): Used for everything else—imported pasta, shampoo, hotel rooms, and nice dinners.
For a long time, the two lived side-by-side. If you were a waiter at a resort in Varadero, you were rich because you got tips in CUC. If you were a brain surgeon working for the state, you were struggle-bus because you were paid in CUP. It created a weird "tourism apartheid" where the people serving the mojitos had ten times the spending power of the people teaching at the universities.

The Messy End of the "Chavito"
By 2013, the government admitted the dual system was a disaster. It distorted prices and made it impossible to tell if state companies were actually making a profit or just surviving on accounting tricks. They announced a plan to unify the currencies.
But they waited. And waited.
Then 2020 hit. The pandemic stopped tourism—Cuba's lifeblood—in its tracks. Trump-era sanctions were squeezing the island harder than ever. The government finally pulled the trigger on January 1, 2021.
The Cuban convertible peso CUC was officially retired.
They gave people a six-month window to exchange their CUC for the national peso (CUP) at a rate of 1 to 24. It was chaos. People stood in massive lines at banks for hours. There were rumors that the bills would become worthless overnight, and honestly, for anyone who missed the deadline, they did. By the end of 2021, the CUC was no longer legal tender.
What Replaced It? (It’s Not What You Think)
You’d think after getting rid of a second currency, things would get simpler. Nope. Not in Cuba.

Instead of two currencies, the island basically moved to a system involving the CUP and something called MLC (Moneda Libremente Convertible). MLC isn't even physical cash. It’s "freely convertible money" that exists on magnetic cards.
If you want to buy high-end groceries or appliances now, you need a card loaded with foreign currency like Dollars or Euros. The government opened "MLC stores" where the shelves are actually stocked, but you can’t pay with the national pesos you were just told to use.
The Black Market Reality
The official rate when the Cuban convertible peso CUC disappeared was 24 CUP to 1 USD. But since the government doesn't actually have enough dollars to sell to the public at that rate, the black market took over.
- The official rate jumped to 120 CUP per Dollar.
- The street rate is often double or triple that.
- Inflation has gone absolutely nuclear.
Can You Still Exchange CUC Today?
This is a common question for people who found an old stash of bills in a travel bag. The short answer? No. Not at a bank, and definitely not at a store in Cuba.
There are some collectors who buy them as souvenirs. You might find a few "Leftover Currency" websites that offer pennies on the dollar for them, but as a medium of exchange, the Cuban convertible peso CUC is a ghost.
If you’re heading to Cuba now, don't even look for them. You’ll be dealing with a mix of CUP (for small street snacks and taxis) and hard cash like Euros or USD for everything else. Most private businesses—the paladares and casas particulares—will look at you like you have three heads if you try to hand them a CUC note.

Real Insights for Navigating the New System
If you are planning a trip or studying the Cuban economy, here is the ground-level reality of the post-CUC world.
Bring small denominations of foreign cash. Since the Cuban convertible peso CUC is gone, cash is king again. But the government makes it hard to change money back. If you change $500 into CUP and don't spend it, you’re stuck with a stack of paper that no one outside the island wants. Change $50 at a time.
Understand the "Street Rate" vs "Official Rate." When you check Google, it might say 1 USD = 120 CUP. When you walk down the street in Havana, someone will offer you 300 CUP. This gap is exactly why the CUC failed; the government tried to dictate value, but the street always wins.
The MLC Card Dilemma. As a tourist, you can buy a temporary MLC card at the airport or certain hotels. It’s useful for some state-run shops, but honestly? Most travelers find it’s easier to just use cash at private businesses.
The Legacy of a Failed Experiment
The Cuban convertible peso CUC was a band-aid. It was meant to bridge the gap between a socialist internal economy and a capitalist global market. Instead, it created two classes of citizens and a mountain of accounting debt that finally collapsed in 2021.
Looking back, the CUC represents a specific era of Cuban history—the era of the "opening," the Obama-era travel boom, and the slow realization that you can't have one foot in two different economic worlds forever.
What you can do now:
- Check your old travel wallets. If you find CUC, keep it as a memento of a time when Cuba had two currencies and zero simple answers.
- If you're heading to the island soon, download an app like El Toque. It tracks the informal exchange rate in real-time. Since the Cuban convertible peso CUC left the building, that's the only way to know what your money is actually worth on the ground.
- Don't rely on credit cards. Most U.S. cards still won't work, and even European ones are subject to "the system is down" more often than not.
The story of the Cuban convertible peso CUC is basically a cautionary tale about what happens when a government tries to control the value of money by decree. It works for a while, until it doesn't. And when it stops working, the people left holding the bags—or the "chavitos"—are the ones who pay the price.
