One international currency regularly tops world rankings of the weakest – and is currently over 100,000 to the pound (GBP).
Weak currencies are ones where the value is low or decreasing in comparison to other currencies. Various factors can drive currency depreciation, including political instability, changes to the inflation rate, and dropping export revenues.
Fintech firm Wise has compiled a list of the 10 lowest-valued globally in 2025, with the Lebanese pound (LBP) ranking first.
The currency has been among the worst-performing for a few years, mainly due to high inflation, a depressed economy, and political instability, as per the website.
It hasn’t helped that the Middle Eastern nation has been struggling with a banking crisis since 2019.
At the time of writing, Wise puts the mid-market exchange rate at 109,373 LBP to 1 GBP.
The second weakest is the Iranian Rial (IRR) which is currently 51,292.50 to the pound.
According to Investopedia, the currency is weak “primarily because of the political instability of Iran”.
Iran’s economy has also struggled for years under crippling international sanctions over its rapidly advancing nuclear program. It’s now thought to enrich uranium at near weapons-grade levels.
In third place is the Vietnamese Dong (VND) which currently has an exchange rate of 31,009 to the pound, mainly due to restrictions on foreign exports, volumes of which have slowed.
The Lao or Laotian Kip (LAK) and The Sierra Leonean leone (SLL) also made the top five with 26,616.90 and 27,803.30 to the pound respectively.
Both currencies are suffering due to a combination of factors, including slow economic growth and high inflation.
