Money is weird. Usually, exchange rates jump around like a caffeinated squirrel, but if you look at 1 USD in Saudi Riyal, you’ll notice something almost eerie. It stays at 3.75. Every single day. For decades.
It’s not a coincidence. It’s not a glitch in the banking app.
Most people checking the rate are either expats sending money home, travelers planning a trip to Riyadh, or investors trying to figure out if the petrodollar is actually dying. Honestly, if you’re looking for a "get rich quick" forex trade here, you’re in the wrong place. The Saudi Arabian Monetary Authority (SAMA)—which is basically their central bank—keeps this thing on a leash.
The Anchor of the Desert
Since 1986, the Saudi Riyal (SAR) has been pegged to the U.S. Dollar.
Think of it like a maritime anchor. While the Euro, the Yen, and the British Pound are tossed around by inflation data and political drama, the Riyal just sits there. The official rate is 1 USD to 3.75 SAR. You might see 3.7502 or 3.7498 on a high-end trading terminal like a Bloomberg Terminal or Reuters Eikon, but for the average person, it’s a flat 3.75.
Why do they do this?
Stability. Saudi Arabia’s entire economy was built on oil. Oil is priced in dollars. If the Riyal fluctuated every time a politician gave a speech, the country's internal accounting would be a nightmare. By locking 1 USD in Saudi Riyal at that specific 3.75 mark, the Kingdom removes the "currency risk" for international oil buyers and domestic planners. It’s predictable. Businesses love predictable.
What You Actually Get at the Counter
Now, let's get real for a second. If you walk into a currency exchange at JFK airport or a mall in Jeddah, you aren't getting 3.75.

That’s the "mid-market rate."
Exchanges have to make money. They do this through something called the "spread." You might find yourself getting 3.65 or 3.70 if you’re lucky. Banks are often the worst offenders. They’ll tell you there’s "zero commission" while giving you a terrible rate. It’s a classic bait-and-switch. If you’re moving large sums—say, for a business deal or buying property in the Neom project—you need to look at specialized fintech transfers like Wise or Revolut. They usually get you much closer to that 3.75 sweet spot than a traditional bank ever will.
Will the Peg Ever Break?
Every few years, rumors start flying.
You’ve probably seen the headlines: "Saudi Arabia Considers Trading Oil in Yuan" or "The End of the Petrodollar."
Economic analysts like those at Goldman Sachs or JP Morgan keep a close eye on this. If the peg broke, the value of 1 USD in Saudi Riyal would likely plummet or spike depending on oil prices at that exact moment. But here's the thing: Saudi Arabia has massive foreign exchange reserves. We’re talking hundreds of billions of dollars. They use this "war chest" to buy or sell their own currency to maintain that 3.75 level.
Giving up the peg would mean massive volatility. For a country trying to diversify its economy through "Vision 2030," volatility is the enemy. It’s much easier to build a trillion-dollar city when you know exactly what your currency will be worth next Tuesday.
The "Hidden" Costs of Fixed Rates
There is a downside.
When you peg your currency to the dollar, you basically hand over your monetary policy to the U.S. Federal Reserve. If the Fed raises interest rates in Washington D.C. to fight American inflation, SAMA usually has to follow suit in Riyadh. Even if the Saudi economy doesn't need higher rates, they do it anyway to prevent money from flowing out of the Riyal and into the Dollar.
It's a trade-off. You get stability, but you lose independence.

For the average person just trying to figure out how many Riyals they get for a hundred bucks, none of this "macro" stuff feels relevant until it hits their purchasing power. If the US Dollar gets stronger globally (the DXY index goes up), the Riyal gets stronger too. This makes a vacation to London or Tokyo cheaper for someone living in Saudi Arabia. But if the Dollar weakens, the Riyal goes down with the ship.
Real World Math for Travelers
Don't overthink it.
The math is simple. If you have 100 USD, you have 375 SAR. If you have 1,000 USD, you have 3,750 SAR.
- Pro Tip: In Saudi Arabia, most people use cards now (Mada, Visa, Mastercard). You don't need to carry huge stacks of cash.
- The Trap: If an ATM asks if you want to be charged in "Your Home Currency" or "Local Currency," always choose Local Currency. * Why? If you choose USD, the ATM owner sets the exchange rate, and they will absolutely rip you off. Let your own bank handle the conversion. They aren't saints, but they're usually cheaper than a random ATM in a gas station.
Beyond the Exchange Rate
The value of 1 USD in Saudi Riyal is more than just a number on a screen. It’s a symbol of a decades-old geopolitical alliance. Since the meeting between King Abdulaziz and President Roosevelt on the USS Quincy in 1945, the dollar and the riyal have been linked in spirit, if not always by a formal peg.
When you see the rate today, you’re looking at the result of global oil markets, central bank reserves, and a whole lot of history.
It’s surprisingly durable. Even during the 2008 financial crisis or the 2020 oil price crash, the 3.75 peg held firm. Speculators tried to bet against it, and they lost billions. The Saudi government has made it very clear that they view the peg as a "red line."
Practical Steps for Handling Your Money
If you are dealing with Saudi Riyals right now, stop checking the "live" charts every five minutes. They won't move. Instead, focus on minimizing fees.
- Use a credit card with no foreign transaction fees. This is the single easiest way to save 3%.
- If you are an expat sending money home, look at apps like STC Pay or Alinma Pay. They often have better internal rates for transfers than the big brick-and-mortar banks.
- Keep a small amount of cash for "souq" shopping or tipping. 500 Riyals is usually plenty for a few days if you’re mostly using cards for hotels and dinners.
- Verify the current "Sell" and "Buy" rates. If a booth is offering you 3.50 for your dollar, walk away. That's a 7% haircut you don't need to take.
The reality of 1 USD in Saudi Riyal is that it's the most boring exchange rate in the world—and that's exactly why it works. It provides a foundation for one of the most ambitious economic transformations in modern history. Whether you're there for Hajj, business in the King Abdullah Financial District, or just passing through, 3.75 is the number to remember.
