Yesterday, I came across an article about which country’s currency is the most expensive in the world. The words caught my attention because I thought that expensive money meant good money. But it turns out that’s not entirely true.

It turns out that the Kuwaiti Dinar is the most expensive, with 1 unit exchanging for $3.26. Kuwait is wealthy from oil, exporting 3 million barrels a day, which makes its economy strong and its currency strong as well. Following that are the Bahraini Dinar (2.65 per USD) and the Omani Rial (2.60 per USD), which are also oil-producing countries.

But what’s interesting is that the British Pound and the Swiss Franc are also on the list. Their strength isn’t due to oil, but because their economies are robust. The UK and Switzerland are ancient and trusted financial centers. The Swiss Franc is also a Safe Haven currency, used by people fleeing market turmoil.

The funny thing is, the Euro is valued at 1.13 per USD. Compared to the top 3 currencies mentioned, the Euro is much cheaper. Yet, the Euro remains an important reserve currency worldwide, ranking second after the USD. This makes me realize that a country’s currency being the most expensive doesn’t depend solely on its value.

For the year 2026, the most expensive currency continues to be the Kuwaiti Dinar, followed by other currencies tied to strong economies—whether oil exporters or global financial hubs. If you’re considering holding a certain currency, you should also consider the country’s credibility, not just whether it’s expensive or not.
