So, you’re looking at the exchange rate between the US dollar and the Saudi riyal. Maybe you're planning a trip to Riyadh, or perhaps you're just curious why the numbers on your screen never seem to move. Seriously, check the charts from last year. Or the year before. Or even back in 2020.
It’s basically a flat line.
If you’ve spent any time looking at USD to riyal Saudi conversions, you’ve probably noticed that 1 USD almost always equals 3.75 SAR. It’s not a coincidence. It’s not some weird market fluke. It’s a deliberate, decades-old policy that keeps the Saudi economy anchored. But honestly, most people don't realize how much this "boring" number actually affects global oil prices and your own wallet if you're doing business in the Middle East.
The 3.75 Secret: Why it Never Changes
Since June 1986—yeah, we’re talking nearly 40 years—the Saudi Central Bank (SAMA) has kept the riyal pegged to the dollar. Specifically, they've set the rate at $1 USD = 3.75 SAR.
Why? Stability.
Saudi Arabia’s biggest export is oil. Oil is priced in dollars. If the riyal bounced around like the Euro or the Yen, the Saudi government’s budget would be a nightmare to manage. By pinning their currency to the greenback, they make sure their oil revenue stays predictable. It sort of takes the guesswork out of the equation for everyone involved.
But here is where it gets interesting. Even though the "official" rate is 3.75, you won’t always get exactly that when you swap cash. Go to an airport exchange counter and you might see 3.65. Use a high-end credit card and you might get 3.74. The "peg" is the target, but the real world always adds a little friction.
The Petrodollar Connection
You’ve probably heard the term "petrodollar." It sounds like something out of a spy novel, but it’s just the reality of how the world buys fuel. Back in the 1970s, the US and Saudi Arabia struck a deal: oil would be sold in dollars, and in exchange, the US would provide security and investment opportunities.
This deal is the backbone of the USD to riyal Saudi relationship. Because the riyal is tied to the dollar, Saudi Arabia effectively imports the US Federal Reserve’s monetary policy. When the Fed raises interest rates in Washington D.C., SAMA usually follows suit in Riyadh. They have to. If they didn't, investors would dump riyals for dollars to get better returns, putting pressure on that 3.75 peg.
What Most People Get Wrong About Exchanging Money
Most travelers and business expats think they should wait for a "better time" to exchange their dollars.
Spoiler alert: there isn't one.
Because the rate is fixed, you aren't "timing the market" like you would with the British Pound. Instead, you're looking for the lowest fees. If you're looking to convert USD to riyal Saudi, your enemy isn't the market—it's the middleman.
- Banks: Usually offer decent rates but might hit you with a flat "international transaction fee."
- Exchange Houses: Places like Al Rajhi or Western Union are everywhere in Saudi. They’re usually fair, but check the "buy" and "sell" spread.
- Airports: Avoid them. They know you’re desperate. You’ll lose 3% to 5% just for the convenience.
- ATMs: Honestly? Often your best bet. Most Saudi ATMs accept international Visa and Mastercard, and the conversion is handled by your home bank at a rate very close to 3.75.
Is the Peg Going Anywhere?
Every few years, someone starts a rumor that Saudi Arabia is going to "unpeg" or switch to a "basket of currencies" (like the Euro and Chinese Yuan).
It hasn't happened yet.
Despite all the talk about BRICS and "de-dollarization" in early 2026, the Saudi Central Bank has been very vocal about sticking to the peg. It’s their shield against inflation. Since the US dollar is the world's reserve currency, it provides a level of credibility that is hard to replace. Plus, with Vision 2030 in full swing, the Kingdom needs a stable currency to attract foreign investors for massive projects like NEOM.

A Quick Reality Check on the Numbers
Let's look at what the math actually looks like for a typical transaction.
If you're buying a $1,000 piece of equipment from the US:
- You need 3,750 Riyals.
- If the riyal were "floating" and dropped 10% (like many emerging market currencies do), that same equipment would suddenly cost you 4,125 Riyals.
- That’s a massive headache for a business owner.
The peg prevents this overnight price hike. It’s a safety net.
How to Get the Best Rate Today
If you need to move money between the US and Saudi Arabia, stop looking at the "market rate." Focus on the platform.
For large transfers, services like Wise or Revolut often beat traditional wire transfers because they don't hide their profit in the exchange rate. They show you the 3.75 (or very close to it) and charge a transparent fee.
If you are physically in the Kingdom, look for local exchange houses in city centers rather than malls. The competition is higher, and the rates are tighter. Most people don't realize that even a 0.01 difference in the rate can mean hundreds of riyals saved on a large transaction.
Actionable Next Steps
- Check your bank's foreign transaction fee. If it's 3%, you're losing money before you even start. Get a travel card with 0% fees.
- Use local ATMs. In Saudi Arabia, ATMs from major banks like SNB (AlAhli) or Al Rajhi are reliable and usually provide the closest rate to the 3.75 peg.
- Don't "stock up" on riyals before you travel. US airports have terrible rates for the Saudi riyal. Wait until you land and hit an ATM at the terminal.
- Monitor SAMA announcements. If you are doing serious business, keep an eye on the Saudi Central Bank’s official website for any rare updates on reserve requirements or interest rate shifts.
The USD to riyal Saudi rate is one of the most stable fixtures in the financial world. Treat it as a constant, focus on minimizing fees, and you'll come out ahead every time.
