If you land at Imam Khomeini International Airport in Tehran, you're going to get confused immediately. You look at your phone, see the official exchange rate for the monetary unit of iran, and think you're rich. Then you try to buy a saffron ice cream or a taxi ride into the city and realize the numbers on the paper bills don't match the numbers people are shouting at you.
It's a mess. Honestly, there's no other way to put it.
Officially, the currency is the Rial (IRR). If you look at a 100,000 banknote, it says "One Hundred Thousand Rials" right there in English and Persian. But talk to any local—literally anyone from a street vendor to a high-end carpet dealer—and they’ll talk to you in Toman. One Toman is ten Rials. It sounds simple, right? Just drop a zero. But when you’re dealing with millions of Rials for a simple dinner, dropping that zero becomes a mental marathon that even locals occasionally trip over.
The Dual-Identity Crisis of the Rial
The monetary unit of iran has been through the ringer. Since the 1979 Revolution, the Rial has lost more than 99% of its value against the US dollar. This isn't just a "business" story; it's a survival story for 85 million people. Because the currency devalued so rapidly over the decades, the numbers grew too large for comfortable conversation. People stopped saying "ten thousand" and started saying "one thousand tomans."
Think about it this way. If you go to a shop and the guy says the price is "fifty," he could mean 50,000 Tomans (which is 500,000 Rials) or he could mean 500,000 Tomans. Context is everything. Usually, if it's a bottle of water, he means 5,000 Tomans. If it’s a pair of shoes, he means 500,000. It's a linguistic shortcut born out of necessity.
The Central Bank of Iran knows this is a problem. Back in 2020, the Iranian parliament actually approved a bill to officially change the currency name back to Toman and slash four zeros. In that plan, 10,000 Rials would become 1 "New Toman." You can actually see this transition on the newer banknotes. The Central Bank started printing "0000" in a very light, almost invisible shade on the 50,000 and 100,000 Rial notes. They’re basically training the public to ignore the zeros before the official changeover is even finished.
Why the Zeros Won't Go Away
Inflation is the ghost in the room. You can't talk about the monetary unit of iran without mentioning the sanctions. When the US pulled out of the JCPOA (the nuclear deal) in 2018, the Rial went into a tailspin.
The "free market" rate and the "official" rate are two different universes. The government keeps an official rate (often around 42,000 Rials to $1) for essential goods like medicine and grain. But nobody on the street can get that rate. If you’re a traveler or a local business owner, you’re looking at the "Bonbast" or "Sana" rates, which are often ten times higher than the official one. It creates a weird, tiered economy.
- Official Rate: Used for government accounting and subsidized imports.
- NIMA Rate: An exchange system for exporters (like oil and petrochemical companies).
- Open Market Rate: What you actually pay at a "Sarrafi" (exchange shop) in Ferdowsi Square.
If you're wondering how people keep track, they use apps. Telegram channels and websites like Bonbast.com are refreshed constantly because the price of a dollar might change three times before lunch. It's high-stakes stuff.
Practical Realities of Spending Money in Iran
Here’s the thing that catches most people off guard: Iran is almost entirely disconnected from the global banking system. Your Visa, Mastercard, or Amex? They are useless pieces of plastic there. Because of sanctions, Iranian banks aren't part of SWIFT.
This means Iran is a cash-heavy society for foreigners, but a digital-pioneer society for locals. Every Iranian has a debit card. Even the guy selling grilled corn on a mountain trail has a mobile Point of Sale (POS) terminal. But since you can’t use your foreign card, you have to carry thick stacks of cash.
Imagine carrying $500 worth of Rials. Even with the highest denomination notes—the 1,000,000 and 2,000,000 Rial "Iran Cheques"—you’re going to have a bulging pocket. These "Cheques" act as banknotes because the actual banknotes are worth so little now. The 50,000 Rial note is basically pocket change, hardly worth the paper it's printed on.
The Rise of the Tourist Card
Because carrying bricks of cash is a massive pain, several Iranian fintech startups and banks started offering "Tourist Cards." Basically, you hand over your Euros or Dollars at the airport or a designated hotel, and they give you a local debit card with a PIN. You get the market exchange rate, and you can swipe away just like a local. Mahcard and Daric are two names that pop up a lot in travel circles. It’s a lifesaver. You avoid the "Toman vs. Rial" math headache at the register because the machine just shows the number and you enter your PIN.
Understanding the "Check" System
If you look at the monetary unit of iran closely, you'll see things called "Iran Cheques." These aren't personal checks you write out. They are issued by the Central Bank and function exactly like cash. Currently, the 1,000,000 Rial (100,000 Toman) and 2,000,000 Rial (200,000 Toman) checks are the most common high-value "bills" in circulation. Without them, the economy would literally grind to a halt because people would need suitcases to pay for groceries.
Is it Cheaper for Travelers?
Yes and no. It’s complicated.
Iran is incredibly cheap if you have "hard currency" like USD or EUR. A high-quality meal might cost you the equivalent of $5. A long-distance bus ride across the desert? Maybe $3. But for the people earning their salary in the monetary unit of iran, it’s a different story. When the Rial drops, the price of milk, eggs, and rent goes up the next morning. It’s a constant race to convert Rials into something stable—gold, real estate, or US dollars.
This has led to a fascinating "hidden" economy. People don't save in Rials. If you have extra cash, you buy "Bahar-e Azadi" gold coins. These are standard gold coins minted by the Central Bank. Their price is tied to the global price of gold and the current dollar-to-rial exchange rate. In a way, gold is the true monetary unit of iran when it comes to long-term savings.

The "Taarof" Factor
When you go to pay, you might encounter Taarof. This is a complex Persian system of etiquette. The shopkeeper might refuse your money at first, saying "Ghabele nadare" (It's not worthy of you/It’s free).
Don't fall for it.
This is a social dance. You must insist on paying. They will refuse again. You insist a third time, and then they will finally tell you the price in Tomans. If you actually walked away without paying, it would be a massive social blunder. It’s a weird quirk where the actual transaction of the monetary unit of iran is secondary to the performance of hospitality.
What to Expect Moving Forward
The Iranian government is still pushing for the "Redenomination." The goal is to remove those four zeros and officially make the Toman the national currency. This isn't just about making math easier; it’s a psychological move. High-zero currencies often signal a "failed" economy to the outside world. By switching to the Toman, the government hopes to restore a sense of prestige to the money.
But a name change doesn't fix inflation.

Unless the underlying economic issues—sanctions, oil export limitations, and fiscal policy—are addressed, the "New Toman" will eventually start growing zeros again. We’ve seen this in countries like Zimbabwe or Turkey in the past. Redenomination is a bandage, not a cure.
Key Takeaways for Navigating Iranian Money
If you're dealing with Iranian currency, whether for travel, business, or just out of curiosity, keep these points in mind. They will save you a lot of grief.
- Always clarify "Toman" or "Rial." If someone says "20," ask "20 Toman or 20,000 Toman?" They almost always mean thousands.
- Ignore the "Official" rate. Unless you are a diplomat or an importer of medicine, the 42,000 Rial rate is a fantasy. Use the market rate found on sites like Bonbast.
- Carry crisp, high-denomination bills. If you are bringing cash to exchange, $50 and $100 bills (or €50 and €100) get better rates and are easier to handle than smaller bills.
- Check the "000" on the notes. Look at the newest 100,000 Rial notes. You'll see the "10" is bold and the "0000" is faint. This is your guide to the future Toman system.
- Don't exchange money at the airport. Well, maybe just $20 for the taxi. The rates at the "Sarrafis" in the city centers (like Tehran's Ferdowsi Square) are much better.
The monetary unit of iran is a reflection of the country's turbulent history and its people's incredible resilience. It’s a currency that requires you to be sharp, skeptical, and quick at math. While the names on the bills might change and the zeros might vanish, the dual-system of Rial and Toman is likely to stay embedded in the culture for a long time.
To handle money in Iran, you need to think like an Iranian: keep your eyes on the market rate, your savings in gold, and always, always double-check the zeros before you hand over a bill.
Actionable Next Steps
- Download a currency converter app that allows for custom rates. Since the official rate is wrong, you'll need to manually input the current "open market" rate to get an accurate sense of what things cost.
- Learn the Persian numbers. While many banknotes have English numerals, many price tags in shops use Persian digits. Learning 0 through 9 takes about ten minutes and prevents you from being overcharged.
- Use a "Tourist Card" service if you are visiting. It eliminates the risk of carrying large amounts of cash and handles the Rial/Toman conversion for you at the point of sale.
- Always ask for the "Toman" price specifically. If you ask "How much is this?" and they say "Five hundred," immediately follow up with "Toman?" to ensure you aren't miscalculating by a factor of ten.
