Have you ever stopped to think about what happens when your salary becomes practically nothing overnight? Yeah, some people are living exactly that in various parts of the world. I received a photo from a friend who was in Lebanon showing a huge bundle of banknotes that looked like Monopoly money. It was more than 50,000 Lebanese pounds. Do you know how much that is in reais? About 3 reais. That made me reflect on something we here in Brazil complain about a lot: the dollar at 5.44 reais. But while we worry about that, there are entire countries where the population deals daily with currencies that have simply collapsed. The real closed 2024 as the worst currency in the world among the main ones, with a devaluation of 21.52%. But that’s nothing compared to what you’ll see in this ranking of the most devalued currencies in the world in 2025.

The global scenario in 2025 was marked by persistent inflation, political crises, and economic instability that turned some currencies into real symbols of fragility. But what really makes a currency lose so much value? The answer isn’t simple and involves several factors that combine explosively.

First: uncontrolled inflation. Here in Brazil, we get nervous when inflation reaches close to 7% per year. Now imagine countries where prices double every month. That’s true hyperinflation, a phenomenon that literally devours savings and people’s wages. Second factor: chronic political instability. When there’s no legal security, when there are coups, civil wars, governments changing every year, investors flee. And then the currency just becomes colored paper with no real value. Third: economic sanctions. When the international community shuts the doors to a country, it loses access to the global financial system. The result? The local currency becomes useless for international trade. Fourth: low international reserves. It’s like having little money in your checking account. If the Central Bank doesn’t have enough dollars to defend the currency, it simply plummets. And finally, capital flight. When even citizens prefer to store dollars informally instead of using the local currency, you know the situation is critical.

Let’s move on to the ranking of the most devalued currencies in the world that are truly at rock bottom.

The Lebanese Pound is the absolute champion of devaluation. Officially, the rate should be 1,507.5 pounds per dollar, but since 2020, that doesn’t exist in the real world. In the black market, you need more than 90,000 pounds to buy 1 dollar. The situation is so critical that banks limit withdrawals and many stores only accept dollars. A journalist told me that in Beirut, Uber drivers ask for payment in dollars because no one wants Lebanese pounds.

The Iranian Rial has been destroyed by American sanctions. With 100 reais, you become a “millionaire” in rials. There are several parallel exchange rates because the government tries to control the exchange but the reality on the streets is completely different. The most interesting thing is that young Iranians are migrating to cryptocurrencies. Bitcoin and Ethereum have become a more reliable store of value than the national currency itself.

The Vietnamese Dong is a different case. Vietnam has a growing economy, but the dong remains historically weak due to monetary policy issues. It’s funny because you withdraw 1 million dongs at an ATM and get an amount worthy of the Money Heist series. Great for tourists, with 50 dollars you feel like a millionaire for a few days. But for Vietnamese people, it means imports become expensive.

The Lao Kip is also on the list. Laos is going through a complicated situation with a small economy, dependence on imports, and constant inflation. The kip is so weak that at the border with Thailand, many merchants prefer to accept Thai baht.

The Indonesian Rupiah has been historically weak. Indonesia is Southeast Asia’s largest economy, but the rupiah has never managed to strengthen. Since 1998, it’s been among the weakest currencies in the world. The upside is that Bali is ridiculously cheap for Brazilian tourists. With 200 reais a day, you can live like a king there.

The Uzbek Sum reflects decades of a closed economy. Uzbekistan has made significant economic reforms in recent years, but the currency remains weak and devalued. The country tries to attract investments but can’t strengthen the currency.

The Guinean Franc is a classic case: resource-rich country but with a weak currency. Guinea has gold and bauxite, but political instability and corruption prevent this wealth from translating into a strong currency.

The Paraguayan Guarani is traditionally weak. Our neighbor has a relatively stable economy, but the currency remains devalued. For us Brazilians, this means Ciudad del Este continues to be a shopping paradise.

The Malagasy Ariary reflects Madagascar’s poverty. It’s one of the poorest nations in the world, and imports are extremely expensive. The population’s international purchasing power is practically zero.

Closing the ranking is the Burundian Franc, so weak that for large purchases, people literally carry bags of money. The chronic political instability in Burundi directly reflects on the national currency.

The ranking of the most devalued currencies in the world in 2025 is not just financial curiosity. It’s a clear reflection of how politics, trust, and economic stability are interconnected. For investors, some lessons are obvious: fragile economies pose huge risks. Cheap currencies may seem like opportunities, but most of these countries are experiencing deep crises. On the other hand, there are real opportunities in tourism and consumption. Destinations with devalued currencies can be financially advantageous for those arriving with dollars or euros.

Monitoring how currencies plummet helps understand the real effects of inflation, corruption, and instability on people’s lives. Paying attention to these factors is a way to see the importance of trust and stability for any economy. Investing is a continuous process of economic and social learning. Ensuring the appreciation of your money involves investing safely in assets that cross borders and are less subject to inflation.
