I noticed something fascinating while looking at recent economic rankings: the most expensive currency in the world is not what you might expect. The Kuwaiti Dinar overwhelmingly dominates, followed by the Bahraini Dinar and the Omani Rial. These three Gulf currencies literally crush the rankings, well ahead of the British Pound or the Swiss Franc.

But here’s the funny thing: countries with the most expensive currency in the world don't necessarily have the most powerful passports. Singapore, South Korea, and Japan top the list for visa-free mobility, while the Gulf petromonarchies are much further behind. It’s an interesting contrast between the raw strength of a currency and the global access a passport offers.

European giants like Germany, France, and the Netherlands also dominate the passport rankings, with access to about 190 destinations. The United States and Canada complete this Western bloc, while Switzerland, despite its strong franc, also remains very well placed in terms of mobility. It’s crazy to see how economic stability and diplomacy play different roles in these two global rankings.
