You've probably looked at a currency chart recently and thought something was broken. The line doesn't move. For decades, the math to convert USD to Saudi Riyals has remained one of the most stable calculations in the global financial markets, but that doesn't mean it's simple. Most people assume that because there is a "fixed" rate, every transaction is the same. They're wrong.
Honestly, the "peg" is a bit of a legend. Since 1986, the Saudi Central Bank (SAMA) has maintained a policy of keeping the Riyal locked to the U.S. Dollar.
The Magic Number: 3.75
The official rate is $1 = 3.75$ SAR.
It’s been that way for a long time. However, if you try to convert USD to Saudi Riyals at a local airport or through a standard retail bank, you will almost never see 3.75. You'll see 3.70, maybe 3.72 if you're lucky. The "peg" is the wholesale rate—the price banks charge each other. For the rest of us, there is the "spread." That spread is where your money disappears.
If you are moving $10,000 for a business deal in Riyadh or just trying to fund a vacation in Jeddah, that small difference between 3.75 and 3.70 isn't just pocket change. It's $500.
Why the Peg Exists
Saudi Arabia prices its oil in dollars. This is the bedrock of the "Petrodollar" system. By keeping their own currency tied to the dollar, they ensure that their massive oil revenues don't fluctuate wildly every time the global markets have a bad day. It provides a level of certainty for the Saudi government's budget. It also makes it very easy for American companies to operate within the Kingdom because they don't have to worry about "currency risk."
But here is the catch.
Because the SAR follows the USD, Saudi Arabia essentially imports American monetary policy. If the Federal Reserve in Washington D.C. raises interest rates to fight inflation, the Saudi Central Bank almost always has to follow suit, regardless of whether the local Saudi economy actually needs higher rates at that moment.
How to Actually Convert USD to Saudi Riyals Without Getting Ripped Off
Most travelers make the mistake of using "No Commission" kiosks. There is no such thing as free. If they aren't charging a fee, they are giving you a terrible exchange rate.
- Avoid Airport Exchange Desks: These are notoriously the worst places on earth to convert USD to Saudi Riyals. They know you're in a rush. They take advantage of it.
- Use Specialized FinTech Apps: Companies like Revolut, Wise (formerly TransferWise), or STC Pay (within Saudi) often offer rates much closer to the official 3.75.
- Local Banks over International Ones: If you are an expat living in the Kingdom, opening a local account at Al Rajhi or SNB (Saudi National Bank) will generally give you better conversion terms than trying to use your Chase or HSBC card at a local ATM.
The Hidden Fees of Credit Cards
Many U.S. credit cards claim they have "No Foreign Transaction Fees." This is true, but it's only half the story. While they won't charge you a flat $5 fee for using the card abroad, they still have to decide what exchange rate to use. Visa and Mastercard usually provide a very fair rate, but some smaller merchants might offer "Dynamic Currency Conversion."
Never, ever let a merchant in Saudi Arabia charge your card in USD. Always choose SAR.
When you choose USD at a point-of-sale terminal, the merchant’s bank chooses the rate. They will almost certainly choose a rate that favors them, not you. By choosing SAR, you leave the conversion to your own bank back home, which is bound by much stricter transparency rules.

Is the Peg Going Away?
Financial pundits love to talk about "De-dollarization." You’ll hear rumors that Saudi Arabia might start pricing oil in Chinese Yuan or a basket of other currencies.
While the Kingdom has signaled more flexibility in its trade partnerships, the SAR to USD peg remains incredibly robust. Breaking the peg would cause massive volatility in the Saudi domestic economy. For now, 3.75 is the anchor.
However, you should keep an eye on "Forward Contracts." In the professional trading world, the "12-month forward" rate for the Riyal sometimes fluctuates. This represents what big banks think might happen a year from now. Even when these forwards show slight stress, SAMA has historically stepped in with its massive foreign exchange reserves to keep the 3.75 line held firm.
Practical Steps for Your Next Conversion
If you're looking to convert USD to Saudi Riyals today, don't just look at the 3.75 headline.
- Check the mid-market rate on a neutral site like Reuters or Bloomberg.
- Compare that against what your bank or app is offering.
- If the difference is more than 0.5%, you’re paying too much.
- For large transfers (over $50,000), skip the apps and talk to a currency broker who can "lock in" a rate.
The Saudi Riyal is one of the few currencies where you can actually predict the cost of your trip or business venture months in advance. Just make sure the middleman isn't taking a bigger cut than they deserve.
Log into your banking app right now and look at the "International Transfer" section. Compare their quoted SAR rate against the 3.75 benchmark. If it's closer to 3.65, it's time to find a new way to move your money. Using a platform like Wise or a local Saudi digital wallet can save you hundreds of dollars on a single transaction.
