Search for a ranking of Gulf currencies and every result gives the same order, year after year. Not because they copy each other — because the order is an administrative decision rather than a market outcome. This page explains why, and shows you the question worth asking instead.

"Per USD" is how many units of that currency buy one US dollar. The lower the number, the higher the unit price — and unit price is all that the popular "strongest currency" ranking measures. Measurement, not advice: this table describes official exchange-rate regimes, not a view on any currency.
The Saudi riyal, UAE dirham, Qatari riyal, Bahraini dinar and Omani rial are each pegged to the dollar at a fixed rate. The central bank defends that rate — supply and demand do not set it — so the price stays inside a very narrow band and the ranking does not move.
The only one pegged to a basket of currencies rather than the dollar alone, and the basket's weights are not published. It therefore moves a little against the dollar — a small movement, but not zero like the others.
A high unit price reflects the rate a country chose when it pegged, not the size or performance of its economy. A currency worth three dollars is not "stronger" than one worth a quarter of a dollar in any sense a trader can use.
While your currency is pegged to the dollar at a fixed rate, its strength against the euro, the pound or the yen is the dollar's strength against them. If the dollar rose today, so did your riyal or dirham, by almost exactly the same amount. So the useful question is not "is the riyal strong today?" — it is "is the dollar strong today?"
The meter runs on the eight freely floating majors: USD, EUR, GBP, JPY, CHF, AUD, NZD and CAD. Pairs like USDSAR and USDAED are traded institutionally for settlement and hedging, but the peg keeps their spot rate close to fixed — so measuring their daily "strength" the same way would mean nothing.
By unit value against the dollar: the Kuwaiti dinar, then the Bahraini dinar, the Omani rial, the Qatari riyal, the UAE dirham and the Saudi riyal. The order has not changed in decades, because five of the six are pegged to the dollar at a fixed rate set by decree and the sixth is pegged to a basket. It is an administrative fact, not a market outcome.
The Kuwaiti dinar has the highest unit price against the dollar in the Gulf, and the highest nominal price among widely traded national currencies. But highest-priced and strongest-today are different things: a high unit price reflects the rate a country chose to peg at, not the size of its economy or how it is performing.
Yes, at 3.75 riyals per dollar since 1986. That means the riyal's strength against the euro, the pound or the yen is effectively the dollar's strength against them: if the dollar rises today, the riyal rises by almost exactly the same amount. The same applies to the UAE dirham, the Qatari riyal, the Bahraini dinar and the Omani rial.
They are traded institutionally for settlement and hedging, and the Bank for International Settlements records them in FX turnover. But the peg keeps the spot rate close to fixed, and availability and cost for a retail trader vary from broker to broker. That is why strength meters — ours included — are built on the eight freely floating majors.
Look at the dollar. While your currency is pegged to it at a fixed rate, the dollar's position among the eight majors today is your currency's position. Our meter shows that ranking, measured now from 28 pairs — measurement, not advice.
