I received a photo from my colleague traveling through Lebanon last week. He was holding a stack of bills that looked like Monopoly money — more than 50,000 Lebanese pounds, something like R$ 3. That made me think: while we complain about the dollar here, there are countries where the currency simply disappeared. And do you know what's the interesting part? The Brazilian real is far from being the worst. There are many more people suffering from devalued currencies than the real out there.

This ranking of the most devalued currencies in the world in 2026 shows a very chaotic global scenario. Uncontrolled inflation, political crises, economic sanctions — all of these have brought down various currencies. But what exactly makes a currency turn into worthless paper?

The answer is simple: trust. When it disappears, everything collapses. Hyperinflation where prices double every month. Constant political instability. Sanctions that cut off access to the international financial system. Central banks with no reserves to defend the currency. And the worst: citizens themselves prefer to stash dollars under the mattress rather than use the local currency. When it gets to that point, you know the situation is serious.

The Lebanese pound is the absolute champion. Officially, it should be 1,507.5 pounds per dollar, but that only exists on paper. In reality, on the streets, you need more than 90,000 pounds to buy 1 dollar. Banks limit withdrawals, stores only accept dollars, Uber drivers ask for foreign currency payments. It’s total chaos.

Then there's the Iranian rial, completely destroyed by American sanctions. With R$ 100, you become a millionaire in rials. Funny thing is, many Iranians have migrated to cryptocurrencies — Bitcoin and Ethereum have become more trustworthy than the national currency itself. When the population prefers digital currency over paper, you know something has gone very wrong.

The Vietnamese dong is different. Vietnam’s economy is growing, but the dong has always been historically weak. You withdraw 1 million dongs and get an absurd stack of notes. Great for tourists, but for Vietnamese people, it means expensive imports and limited international purchasing power.

Next comes the Laotian kip, the Uzbek som, the Guinean franc — all currencies pressured by small economies, dependence on imports, political instability. The Burundian franc caps the list as a currency so weak that people carry money bags for large purchases.

There’s also the Indonesian rupiah, which has never managed to strengthen despite Indonesia being Southeast Asia’s largest economy. Since 1998, it’s been among the weakest. The Malagasy ariary from Madagascar reflects the country’s extreme poverty. The Paraguayan guarani is traditionally weak, making Ciudad del Este a paradise for Brazilian shoppers.

What’s clear is that devalued currencies like the real reflect much bigger problems than simple exchange rate fluctuations. They are signs of collapsing economies, failed governance, lack of institutional trust. For those thinking of investing or traveling, these weak currencies may seem like opportunities, but the truth is more complex.

Yes, destinations with devalued currencies are cheap for tourists. But the local population suffers from inflation, loss of purchasing power, economic uncertainty. It’s a reflection of how politics, stability, and trust are completely interconnected.

The practical lesson here is to understand that a strong currency is no accident. It’s the result of solid institutions, trust, stability. And when you see countries where the population prefers cryptocurrencies or informal dollars over the local currency, you realize the problem is much deeper than exchange rates.

For the Brazilian investor, the lesson is clear: monitoring how currencies collapse helps understand the real effects of inflation, corruption, and instability. And yes, there are countries with currencies more devalued than the real, much more devalued. But that doesn’t make the real strong — it just shows that worse situations are happening in the world.
