You're standing at a kiosk in Riyadh, or maybe you're just staring at a digital wallet in New York, and you notice something weird. The rate to change dollar to riyal is exactly the same as it was yesterday. And the day before. Actually, it’s the same as it was when Top Gun was a new movie.
Since 1986, the Saudi Arabian Monetary Authority (now SAMA) has kept the Saudi Riyal (SAR) locked to the US Dollar at a fixed rate of 3.75.
It’s one of the most stable financial relationships on the planet. Most currencies dance around like caffeine-addicted toddlers, but the Riyal just stays put. If you're trying to move money, this is basically a cheat code for financial planning. You don't have to worry about a sudden 10% drop in value while your wire transfer is "processing."
But honestly, just because the official rate is fixed doesn't mean you won't lose money. Hidden fees are everywhere. Banks, exchange houses, and those convenient airport booths are all trying to take a bite out of your transaction.

The Secret Math of the 3.75 Peg
Most people think "fixed" means "exactly 3.75 at all times for everyone."
That's not quite right. While SAMA keeps the official interbank rate rock-solid, the market has a tiny bit of wiggle room. If you look at high-level trading data from January 14, 2026, you might see the rate flicker between 3.7500 and 3.7505.
Why does this happen? It’s mostly just the cost of doing business between big banks.
Saudi Arabia keeps this peg alive by holding a massive mountain of US Dollars—roughly $439 billion as of late 2025. When the world gets messy and people start doubting the Riyal, the Saudi government just uses those dollars to buy back their own currency. It’s a brute-force way to ensure that when you want to change dollar to riyal, the price is exactly what you expected.
Why Saudi Arabia Sticks to the Dollar
- Oil is the Anchor: Since oil is priced globally in dollars, it makes sense for a country that sells a lot of it to keep their own money tied to the same unit.
- Predictability: Businesses hate surprises. If you’re a construction firm building a "giga-project" in Neom, you need to know your costs won't double because of a currency swing.
- Inflation Control: By pegging to the dollar, Saudi Arabia essentially "imports" the relative stability of the US economy.
Where You Get Ripped Off
When you go to change dollar to riyal, the "rate" you see on Google isn't the rate you get at the counter.
Most physical exchange booths at King Khalid International Airport will give you something like 3.65 or 3.68. They’ll tell you there’s "zero commission," but that’s just marketing talk. They’ve already baked their profit into that lower rate.
If you're moving large sums for business, you've gotta watch out for "correspondent bank fees." This is a sneaky charge where a middleman bank takes $20 or $30 just for passing the money along. It’s annoying, and it adds up fast.
Digital platforms like Wise or Revolut usually get you much closer to the 3.75 mark. They use the mid-market rate and charge a transparent fee upfront. If you’re a tourist, honestly, just using a travel credit card with no foreign transaction fees is usually the smartest move. The card network (Visa or Mastercard) does the conversion at a rate very close to the peg, and you don't have to carry a wad of cash around.
Vision 2030 and the Future of the Peg
There’s been a lot of chatter lately about Saudi Arabia joining BRICS or trading oil in Chinese Yuan.
People get worried that the dollar peg might vanish. If that happened, the cost to change dollar to riyal would suddenly become a volatile mess.
But most experts, including analysts from the IMF, aren't sweating it yet. Saudi Arabia’s Vision 2030 plan requires massive foreign investment. Investors like the dollar peg because it removes "currency risk." Breaking the peg now would be like trying to change the tires on a car while it's doing 100 mph on the highway.
Riyadh is focused on diversifying the economy—tourism, mining, and tech—but the dollar remains the backbone. Even if they start accepting other currencies for some oil contracts, they’ll likely keep the Riyal tied to the greenback to keep the domestic economy stable.
Practical Tips for Converting Your Money
- Avoid Airport Booths: They are almost always the most expensive way to get Riyals. Use an ATM in the city instead.
- Check the "Sell" vs "Buy" spread: A wide gap between these two numbers means the exchange house is taking a huge cut.
- Use Local Cards: If you’re staying for a while, apps like STC Pay are huge in Saudi and offer great internal rates.
- Wire Transfers: For large amounts, use a specialized FX broker rather than your standard retail bank. You can save thousands on a six-figure transfer.
Real-World Example: Sending $1,000
If you send $1,000 through a typical high-street bank, you might end up with about 3,670 SAR after their "adjusted" exchange rate and a $35 wire fee.
If you use a specialized digital service, you’ll likely get 3,740 SAR even after their small fee.
That’s a 70 Riyal difference—enough for a really nice dinner in downtown Jeddah.

The peg makes the math easy, but the provider you choose makes the difference. Always look for the number 3.75. The further away the offered rate is from that number, the more you're paying for the convenience of the service.
To get the best value, check the current mid-market rate on a site like Reuters or Bloomberg right before you commit to a transaction. If the provider is offering you anything less than 3.70, you should probably look for another option. For large business transactions, negotiate a "fixed spread" with your bank so you always know exactly how many points away from the 3.75 peg you are paying.
