If you’ve ever looked at a chart for the SAR to USD currency pair, you probably thought your screen was frozen. It’s a flat line. Seriously. While the Japanese Yen swings wildly based on interest rate jitters and the Euro bounces around every time a central banker sneezes, the Saudi Riyal just... sits there.
Since 1986, the Saudi Arabian Monetary Authority (now the Saudi Central Bank, or SAMA) has kept the exchange rate locked at 3.75 SAR to 1 USD. It’s one of the most durable currency pegs in modern financial history. But "stable" doesn't mean "boring." For anyone moving money between Riyadh and New York, whether for oil contracts or a family vacation, understanding the mechanics behind this peg is the difference between smart planning and getting stung by hidden fees.
The 3.75 Magic Number
Most people think exchange rates are just a reflection of how well a country is doing. That's true for "floating" currencies. But the SAR to USD currency relationship is a "fixed" one.
The Saudi government decided decades ago that stability was worth more than flexibility. Because their entire economy was built on oil—which is priced globally in US Dollars—having a fluctuating currency created a nightmare for the national budget. Imagine trying to build a city like Neom if the value of your money changed by 10% every week. You couldn't. By pinning the Riyal to the Dollar, Saudi Arabia essentially outsourced its inflation management to the U.S. Federal Reserve.
Does it ever break?
Speculators have tried to "break" the peg before. Whenever oil prices tank, like they did in 2014 or during the 2020 lockdowns, hedge funds start betting that Saudi Arabia will run out of Dollars and be forced to devalue the Riyal. They haven't won yet.
Saudi Arabia sits on hundreds of billions of dollars in foreign exchange reserves. When the Riyal feels pressure, SAMA simply dips into those reserves to buy up Riyals and maintain the 3.75 ratio. It’s a massive game of financial poker, and the House (Riyadh) has a very deep stack of chips.

The Real Cost of "No Change"
Wait. If the rate is locked at 3.75, why does your banking app show you a different number? This is where people get frustrated.
You go to exchange SAR to USD currency and you see 3.78 or 3.80. That’s the "spread." Banks and exchange houses like Al Rajhi, STC Pay, or Western Union need to make a profit. They aren't going to give you the mid-market rate because they have overhead, staff, and a desire to make money off your transaction.
- The Interbank Rate: This is the pure 3.75 rate. Only big banks trading millions get this.
- The Retail Rate: This is what you get at the airport or on your phone. It usually includes a 1% to 3% markup.
- Transfer Fees: Sometimes the rate looks good, but the "service fee" kills the deal.
Honestly, if you're transferring large amounts, a 0.5% difference in the rate can mean thousands of dollars staying in your pocket or disappearing into bank profit.
Why the US Federal Reserve Runs Riyadh’s Interest Rates
Here is the weird part about the SAR to USD currency peg: Saudi Arabia doesn't really have its own independent monetary policy.
When Jerome Powell and the Fed raise interest rates in Washington D.C. to fight inflation, SAMA almost always follows suit within hours. They have to. If interest rates in the US are 5% and rates in Saudi are only 2%, big investors would sell all their Riyals to buy Dollars and earn that extra 3%. This "capital flight" would put massive pressure on the peg.

So, when you see news about US inflation, it actually matters for your car loan in Dammam. It’s a weird, interconnected web that keeps the Riyal stable but ties the Kingdom’s hands when it comes to local economic tuning.
Vision 2030 and the Future of the Riyal
There is a lot of chatter lately about "de-dollarization." You’ve probably seen the headlines about Saudi Arabia considering selling oil in Chinese Yuan or joining the BRICS nations.
Don't panic.
Changing the SAR to USD currency peg would be a monumental shift that would shake the foundations of the Saudi economy. Most experts, including analysts at Goldman Sachs and the IMF, believe the peg is here to stay for the foreseeable future. The stability it provides for the massive "Vision 2030" infrastructure projects is too valuable to throw away for a political statement.
However, the Kingdom is diversifying. They are putting more money into the Public Investment Fund (PIF) and investing in global tech, sports, and tourism. As the economy becomes less dependent on "Petrodollars," the necessity of the peg might diminish over the next twenty years. But for today, tomorrow, and next year? 3.75 is the number.

How to Actually Get the Best Exchange Rate
If you are moving money, don't just click "send" on your primary bank account.
- Check the "Hidden" Spread: Take the amount of USD you are receiving and divide it by the SAR you are spending. If the result isn't close to 3.75, you're getting ripped off.
- Use Neo-Banks: Apps like Revolut or specialized transfer services often have much tighter spreads than traditional brick-and-mortar banks.
- Watch the Weekends: The forex market closes on weekends. Some platforms add an extra "buffer" fee on Saturdays and Sundays to protect themselves against any news that might break before Monday. Try to exchange during mid-week market hours.
- Avoid Airport Booths: This is the golden rule of travel. Airport exchange counters are notorious for "convenience" rates that can be 5-10% worse than the actual market rate.
Actionable Steps for Managing Your SAR and USD
Moving forward, treat the Riyal as a proxy for the Dollar. If you are an expat earning in SAR, your purchasing power globally is tied to the strength of the US Dollar. When the USD is "strong" against the Euro or the British Pound, your Riyals go further on vacation in London or Paris.
To optimize your currency strategy:
- Audit your transfer methods: Compare three different services (e.g., a local Saudi bank, a digital wallet, and a dedicated FX broker) for a $1,000 equivalent transfer. You'll likely see a spread of 50 to 150 Riyals between the best and worst.
- Monitor Fed Announcements: Since SAMA follows the Fed, keep an eye on US interest rate trajectories if you have floating-rate debt in Saudi Arabia.
- Hedge for the long term: If you have long-term liabilities in USD but earn in SAR, keep a small reserve of USD in a high-yield savings account to capture interest rates directly, rather than waiting for local banks to pass those rates on to you.
The SAR to USD currency peg is a bedrock of global finance that isn't going anywhere soon. Respect the 3.75, but don't let the banks use that stability to hide their fees.
