I just reviewed a ranking of the 20 most important currencies in the world, and it's interesting to see how they are distributed. The Kuwaiti dinar remains the strongest currency, followed by the Bahraini dinar and the Omani rial. It makes sense considering the Gulf oil economies.

The curious thing is to see how currencies from developed countries like the Swiss franc, the British pound, and the euro maintain solid positions in the top. The US dollar is also high up at position 9, although many believe it should be higher.

If we look further down the ranking, we find the Canadian dollar, the Singapore dollar, and the Australian dollar. All are currencies with stable economies. Even the Brazilian real appears on the list, which says something about how these 20 most important currencies globally are measured.

The truth is, these currency rankings are useful for understanding the relative strength of different economies, although exchange rates fluctuate constantly. But overall, the positions tend to stay quite stable in the long term.
