Money is weird. We look at the dollar to riyal exchange rate and see a flat line, a steady $1$ to $3.75$ ratio that hasn't budged since the mid-eighties. Most people just assume it's "fixed" and move on. But there’s a massive machinery humming under the hood of the Saudi Central Bank (SAMA) that keeps that number locked in place, and honestly, if you’re doing business in the Gulf or just traveling to Riyadh, understanding why that line doesn’t move is way more important than just knowing the math.
It’s about stability. Imagine trying to run a global oil giant like Aramco if your local currency swung wildly against the currency your product is priced in. Since oil is priced in Greenbacks, the peg is basically a shield against total chaos.
The 3.75 Reality: How the Dollar to Riyal Stayed Put
Since 1986, the Saudi Arabian Riyal (SAR) has been pegged to the U.S. Dollar (USD). Specifically, it’s fixed at $3.75$ SAR per $1$ USD. You’ll see slight fluctuations at currency exchange booths—maybe $3.74$ or $3.76$—but that’s just the middleman taking their cut. The actual central bank rate is a rock.
Why? Well, Saudi Arabia is the world’s biggest oil exporter. Because the global oil market trades almost exclusively in dollars, the Saudi economy is naturally "dollarized" from the jump. If the riyal were allowed to float—meaning its value was determined by market supply and demand—every time the price of a barrel of Brent crude dropped, the riyal would likely crash too. That would make imports (which Saudi Arabia relies on heavily for everything from iPhones to Toyotas) insanely expensive for the average person in Jeddah or Dammam.

Maintaining this isn't free. SAMA has to keep massive piles of foreign exchange reserves. Think of it as a giant war chest. When there is too much pressure on the riyal to devalue, the central bank steps in and buys its own currency using those dollars. It’s a constant balancing act.
Is the Peg Ever Going to Break?
Every few years, when oil prices tank, speculators start betting against the riyal. They think, "This is it, the Saudis can't afford to keep the dollar to riyal rate where it is." We saw this in 2015 and again during the 2020 lockdowns. 12-month forward contracts—basically bets on what the rate will be in a year—started to price in a weaker riyal.
But it never happens.
The Saudi government has repeatedly signaled that the peg is a "strategic choice." They have hundreds of billions in the Saudi Central Bank and the Public Investment Fund (PIF) to defend it. Breaking the peg would destroy investor confidence in Vision 2030. People don't realize that the peg isn't just a financial policy; it's a promise of predictability. If you're a foreign company building a "giga-project" like NEOM, you need to know that your 10-year contract won't be worth half as much in USD terms by the time the ribbon is cut.
The Fed Factor
Here is the catch. Because of the peg, Saudi Arabia basically gives up its own independent monetary policy. When the U.S. Federal Reserve raises interest rates to fight inflation in America, SAMA usually has to follow suit within hours.

It doesn't matter if the Saudi economy is slowing down and needs lower rates to encourage spending. If the Fed hikes, SAMA hikes. If they didn't, capital would fly out of the Kingdom to chase higher yields in the U.S., putting unbearable pressure on the exchange rate. It’s a trade-off. You get stability, but you lose the steering wheel for your own interest rates.
What This Means for Your Wallet
If you're an expat sending money home or a business owner importing goods, the dollar to riyal relationship is your best friend. It removes "exchange rate risk."
- For Travelers: If you're coming from the U.S., you don't need to check the charts every morning. $100$ is $375$ riyals. Period.
- For Investors: You're basically holding "dollar-lite." Your assets in Saudi are shielded from the volatility that plagues other emerging market currencies like the Turkish Lira or the Egyptian Pound.
- For Expats: Many expats from India, Pakistan, or the Philippines track the USD/SAR rate because their home currencies fluctuate against the dollar. If the dollar gets stronger globally, their riyal-based salary suddenly buys a lot more rupees or pesos back home.
The Future: Diversification and Digital Riyals
We’re hearing more talk lately about "petroyuan" or trading oil in currencies other than the dollar. China is a massive buyer of Saudi crude, so it makes sense they’d want to use their own money. However, switching away from the dollar is a logistical nightmare. The entire global banking system is built on the dollar (SWIFT, etc.).
Even if Saudi Arabia starts taking some payments in Yuan, they are highly unlikely to drop the dollar peg anytime soon. It’s too baked into their sovereign wealth strategy.
What we are seeing is the rise of the "Digital Riyal." SAMA has been experimenting with wholesale Central Bank Digital Currencies (CBDCs) for cross-border settlements. This doesn't change the value of the riyal, but it makes moving it faster and cheaper. It’s a tech upgrade, not a value shift.
Actual Steps You Should Take
Stop paying high bank fees. Seriously. Even though the rate is pegged, banks will still try to skin you on the "spread."
- Use Digital Wallets: In Saudi, apps like STC Pay or Urpay often give much better conversion rates for international transfers than traditional brick-and-mortar banks. They compete on that tiny margin between $3.74$ and $3.75$.
- Avoid Airport Exchanges: This is a universal rule, but it applies here too. Airport booths often charge a "convenience fee" that effectively makes your $1$ dollar worth only $3.50$ riyals. Use an ATM instead.
- Monitor the Fed: If you have a loan in Saudi Arabia, keep an eye on Jerome Powell and the U.S. Federal Reserve. If the U.S. looks like it’s going to keep rates high, expect your Saudi bank to keep your borrowing costs high too.
- Hedge your home currency: If you are an expat, don't just wait for the "perfect" time to send money. Because the SAR is pegged to the USD, your primary concern isn't the riyal—it's how your home currency is performing against the dollar. If your home currency is at a multi-year high, that's the time to send money, because your riyals are essentially dollars.
The dollar to riyal peg is the anchor of the Saudi economy. It’s survived oil crashes, regional wars, and global pandemics. While the world of finance is changing, that $3.75$ number is likely the most stable thing in your portfolio. Just don't let the banks convince you that "fixed" means "free" when it comes to transfer fees.
