I've always thought that the dollar was the strongest currency in the world, but after I started studying forex, I realized there are several currencies worth much more out there. The dollar, euro, and pound are the names that come to everyone's mind, but the truth is that the 20 most valued currencies in the world include some quite interesting ones that we haven't even heard of.

I started researching this because I wanted to diversify my portfolio and get out of the real. I discovered that the Kuwaiti Dinar is the most expensive currency in the world in 2026, trading at around 3.25 dollars. Then comes the Bahraini Dinar (2.65 USD), Omani Rial (2.60 USD), and other Middle Eastern currencies that have incredible economic stability.

What I found most interesting is that among the 20 most valued currencies globally, we have everything from currencies of wealthy countries like Switzerland and the UK to currencies of financial centers that we barely know, like the Cayman Islands. The British pound remains strong at around 1.32 dollars, the Swiss franc at 1.12, and the euro maintains its 1.09 dollars.

For those looking to invest in foreign currency, it's worth focusing on currencies linked to stable economies with good international reserves. The Swiss franc is known as a 'safe haven'—when the market gets tense, everyone rushes to it. The Japanese yen also continues to be heavily traded, despite Japan's monetary easing.

The Canadian dollar (0.74 USD) and the Singapore dollar (0.74 USD) are interesting because they are tied to strong sectors: oil and technology, respectively. The Australian dollar (0.66 USD) benefits from mineral and gold exports.

What makes a currency expensive isn't just the price itself, but the country's economic stability, low inflation, solid international reserves, and relevance in the forex market. The 20 most valued currencies in the world generally share these characteristics.

If you want to start trading currencies, the important thing is to understand that it involves risk. Exchange rate volatility is real, especially with geopolitical crises and changes in central banks' monetary policies. But if you have a good risk strategy and study beforehand, you can make money with it.

In the end, investing in foreign currencies is a legitimate way to protect yourself against inflation of the real and diversify. But it's not about getting rich quickly—it's more about asset protection.
