Money is weird. Usually, exchange rates are like a heart rate monitor in a high-intensity interval training class—jumping up, crashing down, and making everyone nervous. But when you look at the relationship of 1 dollar to 1 saudi riyal, things get strangely quiet. It’s a flatline. Not the scary medical kind, but the rock-solid, predictable kind that global oil markets are built on.
Honestly, if you go to a currency exchange in Riyadh or look at a Forex ticker in New York, you’re going to see the same number you would have seen in 1986. That's not a typo. Since June of that year, the Saudi riyal has been officially pegged to the U.S. dollar at a rate of 3.75.
You've probably wondered why. Most currencies float. They drift based on how many iPhones a country sells or how much interest their central bank is paying. But Saudi Arabia decided decades ago that they’d rather have stability than a floating rate. It’s a massive commitment. Basically, the Saudi Central Bank (SAMA) promises to buy and sell riyals at that exact rate, no matter what happens to the price of oil or the geopolitical weather.
The Secret History of the 3.75 Peg
It wasn't always this way, but it's been this way for a long time. Back in the early 80s, the rate wobbled a bit more. But the Kingdom realized that since they price their most valuable export—crude oil—in U.S. dollars, it made a whole lot of sense to keep their own currency tied to those same dollars. It removes the "currency risk." If oil stays at $80 a barrel, they know exactly how many riyals that is. Every single time.
This isn't just some casual agreement. It’s a foundational pillar of the global "Petrodollar" system. When you're looking at 1 dollar to 1 saudi riyal, you aren't just looking at a price; you're looking at a geopolitical handshake.
The Saudi Central Bank maintains massive foreign exchange reserves to protect this. If speculators try to bet against the riyal, SAMA can just dump dollars into the market to keep the price exactly where it needs to be. It's a show of force. They have hundreds of billions of dollars in the bank specifically to make sure that 3.75 number doesn't budge. Occasionally, when oil prices crash—like they did in 2014 or during the 2020 lockdowns—the "forwards" market starts to sweat. Traders bet that Saudi will finally break the peg. They haven't. They won't. It’s a point of pride and economic necessity.
Why it feels different at the airport
Now, if you are a traveler, you’re probably thinking, "Wait, I didn't get 3.75 when I landed in Jeddah."
That's because of the "spread." Banks and kiosks have to make money somehow. They’ll give you 3.70 or maybe 3.65 if they’re really greedy. But the official, interbank rate—the one that actually matters for the economy—is glued to 3.75.
- The Official Rate: $1 = 3.75 SAR
- The Inverse: 1 SAR = $0.2666... (roughly 27 cents)
Most people get confused by the math because it isn't a 1-to-1 ratio. It would be easier if it were. But since it’s fixed, you can basically do the math in your head once you get the hang of it. Four riyals is a little more than a dollar. Forty riyals is about eleven bucks. Simple. Sorta.
The Massive Impact on Vision 2030
Saudi Arabia is currently undergoing a total facelift. It’s called Vision 2030. They are building cities in the desert like NEOM and trying to turn the country into a tourism hub. For an investor coming from overseas, the 1 dollar to 1 saudi riyal stability is a huge magnet.
Imagine you’re a developer putting $500 million into a luxury resort on the Red Sea. If the currency crashed by 20% next year, your investment would be worth 20% less in dollar terms. That’s a nightmare. But in Saudi, that risk is effectively zero as long as the peg holds. It’s a "safe haven" feel in a region that can sometimes feel volatile.
However, there is a catch. Because the riyal is pegged to the dollar, Saudi Arabia basically has to follow the U.S. Federal Reserve’s lead on interest rates. If Jerome Powell raises rates in Washington D.C. to fight inflation, the Saudi Central Bank usually has to follow suit within hours. They don't really have an independent monetary policy. It’s the price they pay for that stability. If they didn't follow the Fed, money would either flood out of or into the country, putting pressure on that 3.75 anchor.
What happens if the dollar gets too strong?
This is where things get tricky. When the U.S. dollar gets super strong against the Euro or the Yen, the Saudi riyal gets strong right along with it.
That sounds good, right?
Well, not always. If the riyal is too strong, it makes Saudi exports (other than oil) more expensive for the rest of the world. It also makes it pricier for European or Asian tourists to visit. If you're a German traveler and the Euro is weak against the dollar, your trip to AlUla just got a lot more expensive because the riyal is hitched to the dollar's wagon. It's a double-edged sword that the Saudi Ministry of Finance watches constantly.
Common Misconceptions About the Exchange
I hear people say the riyal is "weak" because it takes 3.75 of them to buy a dollar. That’s just not how currency works. The nominal value doesn't equal the strength of the economy. If that were true, the Japanese Yen would be "weak" because it’s usually over 100 to the dollar, and the Kuwaiti Dinar would be the "strongest" economy in the world because it’s worth $3.25.
It’s about purchasing power and stability.
And don't expect the peg to vanish anytime soon. People have been predicting the end of the dollar-riyal peg for forty years. Every time there’s a recession or a dip in oil, the "experts" come out and say, "This is it, they're going to float the currency!"
It hasn't happened.
The Saudi government knows that the peg is their greatest tool for controlling inflation. Since they import a huge amount of their food and manufactured goods, keeping the currency stable against the dollar keeps prices at the grocery store predictable. If the riyal dropped, the price of a bag of rice or a new car would skyrocket instantly.
Practical Tips for Dealing With Riyals
If you’re actually moving money—maybe you’re an expat working in Aramco or a freelancer taking a contract in Riyadh—stop using standard bank transfers. They will kill you on the hidden fees.

- Use specialized apps. Services like STC Pay or specialized FX brokers often give you much closer to the 3.75 mid-market rate than a traditional high-street bank.
- Check the "Forwards" market. If you want to know if the market is nervous about the riyal, look at 12-month SAR forwards. If that number starts creeping up toward 3.80 or 3.90, it means traders are hedging against a devaluation. (Spoiler: It rarely stays there for long).
- Local Cash is King... sort of. Saudi is becoming incredibly digital. You can use Apple Pay almost everywhere, from huge malls to tiny coffee shops. Your bank will handle the 3.75 conversion behind the scenes, though they'll usually tack on a 2-3% "foreign transaction fee."
What Most People Get Wrong
The biggest mistake is thinking the 1 dollar to 1 saudi riyal rate is a "market price." It’s not. It’s a policy.
It is a deliberate choice made by the government. In the world of economics, this is known as a "fixed exchange rate regime." It requires massive discipline. You can't just print money whenever you want if you have a fixed peg, or you'll run out of the dollars needed to defend it.
The relationship between the greenback and the riyal is essentially a mirror. When the dollar loses value globally, the riyal loses value globally. When the dollar is the king of the mountain, the riyal sits right there on the throne with it. For the foreseeable future, 3.75 is the only number that matters.
Actionable Steps for Navigating the Currency
- For Travelers: Don't exchange your money at the airport in your home country. You'll get a terrible rate. Wait until you get to Saudi and use an ATM or a local "Saraf" (money changer). The rate is so stable that you won't see the wild fluctuations you’d find in Turkey or Egypt.
- For Investors: Focus on the "Cost of Carry." Since Saudi rates track U.S. rates, your main concern isn't the exchange rate moving; it's the interest rate differential and the inflation rate within the Kingdom compared to the U.S.
- For Expats: If you are getting paid in riyals, you are essentially getting paid in "locked dollars." This is great for sending money back to the U.S., but keep an eye on the exchange rate of your home country if you aren't American. If you're sending money to India or the Philippines, the riyal-to-rupee or riyal-to-peso rate will fluctuate every single day because those currencies float against the dollar.
The riyal is a boring currency, and in the world of finance, boring is beautiful. It means you don't have to wake up at 4:00 AM to check if your savings account lost 10% of its value overnight. As long as the world needs oil and the U.S. dollar remains the global reserve currency, that 1 dollar to 1 saudi riyal relationship is likely the most stable thing in your portfolio. Keep your math simple: divide by four, add a little back, and you’re pretty much there.
