The 10 Most Devalued Currencies in the World in 2025: A Guide to Global Economic Fragility

Why Do Some Currencies Lose So Much Value?

The story is always the same: rampant inflation, endless political crises, lack of international confidence. When these factors combine, a currency not only weakens — it collapses. The real closed 2024 as the worst currency among the main ones, with a decline of 21.52%, but this pales in comparison to what happens in other economies around the world.

There are five pillars that determine the fate of any weak currency:

Hyperinflation: When prices double monthly, the population abandons the national currency. In Brazil, we worry about inflation above 5%, but in some countries, this is everyday reality.

Chronic Political Instability: Coups, internal conflicts, and constant government changes scare off investors. Without legal security, no one wants to store wealth in local assets.

International Sanctions: Economic isolation forces countries to rely on parallel financial systems, making the national currency virtually useless for global transactions.

Insufficient Foreign Currency Reserves: When the Central Bank does not have enough dollars to defend the parity, collapse is inevitable.

Mass Capital Flight: Citizens prefer to hold foreign currency informally rather than trust the local currency — a sign that the situation has reached a critical point.

The Ranking: The 10 Most Devalued Currencies in the World in 2025

1. Lebanese Pound (LBP) — The Biggest Devaluation

Quote: 1 million LBP = R$ 61.00

Lebanon has lost its currency. The official rate of 1,507.5 pounds per dollar does not exist in practice. In the parallel market, where real transactions occur, it takes more than 90,000 pounds to get one dollar. Banks ration withdrawals, shops reject the national currency, and even ride-share drivers demand payment in dollars. This is the most extreme case of global devaluation.

2. Iranian Rial (IRR) — Economic Sanction

Quote: 1 real = 7,751.94 rials

American sanctions have turned the rial into paper. R$ 100 turns anyone into an “Iranian millionaire.” The government tries to control exchange rates through multiple rates, but street economy works differently. The most interesting phenomenon: young Iranians have migrated en masse to cryptocurrencies. Bitcoin and Ethereum have become a safer store of value than the national currency, indicating that the population has lost total confidence in local economic stability.

3. Vietnamese Dong (VND) — Weak but Stable

Quote: Approximately 25,000 VND per dollar

Vietnam is growing economically, but its currency remains historically weak due to political decisions. Withdrawing 1 million dong produces stacks of notes — great for tourism, bad for international purchasing power. Imports become expensive, and the population feels the weight of a devalued currency.

4. Laotian Kip (LAK) — Economic Dependence

Quote: Approximately 21,000 LAK per dollar

Small economy, constant imports, and persistent inflation define Laos. The currency is so weak that border traders with Thailand refuse kip and ask for Thai baht in exchange.

5. Indonesian Rupiah (IDR) — Historically Weak

Quote: Approximately 15,500 IDR per dollar

Largest economy in Southeast Asia, but the rupiah has never strengthened since the 1998 crisis. This means Bali is cheap for tourists: R$ 200 daily guarantees maximum comfort. For Indonesians, it means dependence on expensive imports.

6. Uzbek Sum (UZS) — Legacy of a Closed Economy

Quote: About 12,800 UZS per dollar

Recent economic reforms have not been enough to strengthen the Uzbek sum. Decades of isolation have left deep marks. The country seeks to attract foreign investment, but the currency remains weak.

7. Guinean Franc (GNF) — Wealth That Cannot Be Converted

Quote: Approximately 8,600 GNF per dollar

Guinea has abundant gold and bauxite, but political instability and corruption prevent this wealth from translating into a strong currency. Natural resources do not guarantee monetary stability without good governance.

8. Paraguayan Guarani (PYG) — Weak Regionally

Quote: Approximately 7.42 PYG per real

Relatively stable economy, but the guarani has never gained strength. Brazilians take advantage for shopping in Ciudad del Este, where the weak currency compensates with low prices.

9. Malagasy Ariary (MGA) — Poverty Reflected

Quote: Approximately 4,500 MGA per dollar

Madagascar faces one of the worst global economic scenarios. Imports are exorbitant, and the population has virtually no international purchasing power.

10. Burundian Franc (BIF) — Currency in Crisis

Quote: About 550.06 BIF per real

Chronic political instability directly reflects on the currency. The devaluation is so severe that large transactions require carrying bundles of notes — a picture that sums up the economic collapse.

What Does This Mean for Investors

The most devalued currencies in the world are not just financial curiosities. They are mirrors of broken economies, reflecting how politics, trust, and stability intertwine.

For investors, three lessons emerge:

First: Fragile economies pose immense risks. Cheap currencies may seem like opportunities, but most of these countries are in deep crises that limit real gains.

Second: Tourism and consumption can benefit. Destinations with devalued currencies offer financial advantages for those arriving with strong currency — whether dollar, euro, or real.

Third: Understanding monetary devaluation teaches practical macroeconomic lessons. Watching how currencies collapse helps understand inflation, corruption, and instability in real time.

The conclusion is simple: trust, stability, and good governance determine the value of any currency. Those who understand this dynamic are better positioned to protect and grow their capital in an economically volatile world.
