You’ve got a hundred bucks. In your head, you probably check the mid-market rate on Google or XE, see something like 7.75 or 7.80, and think, "Sweet, I've got nearly 800 quetzales." Honestly? You don't. That number you see on the big search engines is the "interbank" rate—the price banks charge each other for massive, multi-million dollar moves. For us regular people, the reality of converting 100 dolares a quetzales is a bit more complicated, and frankly, a bit more expensive.
Money is weird. Especially when it crosses borders into Guatemala.
The Quetzal (GTQ) has been one of the most stable currencies in Latin America for decades, which is kind of a miracle if you look at the neighbors. But that stability comes at a price. When you walk into a Banco Industrial or a Banrural with a hundred-dollar bill, the teller isn't going to give you that Google rate. They have a "buy" rate and a "sell" rate. You’re selling your dollars, so you get the lower end of the stick. If the market says 7.78, the bank might give you 7.55. On 100 dollars, that’s a 23 quetzal difference. That is a whole lunch at a comedor gone just in the "spread."
Why 100 dolares a quetzales fluctuates more than you think
The Banco de Guatemala (BANGUAT) keeps a tight leash on the exchange rate. They use something called a managed float. Basically, if the quetzal starts getting too strong or too weak, the central bank jumps in and buys or sells dollars to smooth things out. This is why you rarely see the quetzal crash like the Argentine peso.
But here’s the kicker: seasonality.
During December, thousands of Guatemalans living in the U.S. send home "remesas." This massive influx of dollars actually makes the dollar weaker locally because there’s so much supply. If you are trying to change 100 dolares a quetzales during the Christmas rush or Holy Week (Semana Santa), you might actually get fewer quetzales than you would in a random Tuesday in August. It feels backwards, right? More demand for local currency usually means your dollar buys less.
Then there's the physical condition of the money.

In Guatemala, banks are notoriously picky. If your hundred-dollar bill has a tiny tear, a stray ink mark from a pen, or even a heavy fold down the middle, a lot of places will flat-out refuse it. Or worse, they’ll send you to a "casa de cambio" that charges a "damaged bill" fee. You might end up getting a rate of 7.20 instead of 7.70. It’s annoying. It’s arguably a bit ridiculous. But it’s the reality on the ground in Guatemala City or Antigua.
Where to actually do the swap
Most travelers or folks receiving money think the airport is the easiest spot. Don't do it. Global Exchange and similar booths at La Aurora International Airport are notorious for terrible rates. You could easily lose 10% of your value right there at the gate.
- Local Banks: Banco Industrial (BI), Banrural, and G&T Continental are the big three. You’ll need your passport. No passport, no service. Expect a wait. Lines in Guatemalan banks are a local pastime.
- ATMs (Cajeros): Usually the 5B or BAC machines. They often give a decent rate, but your home bank might hit you with a $5 international fee. If you’re only pulling out the equivalent of 100 dolares a quetzales, that $5 fee is a massive 5% hit. It only makes sense if you’re pulling out more.
- Payeras/Remittance Apps: If you’re sending money to someone, apps like Remitly or Wise usually beat the bank rates. They’re transparent. You see the fee upfront.
The "Street" Rate vs. The "Official" Rate
In some countries, there’s a massive "blue market" or black market for dollars. Guatemala isn't really like that. The street rate and the bank rate are usually pretty close. However, if you're in a pinch in a place like Panajachel or Tikal, a hotel might offer to take your dollars at a flat 7.00 rate just for the convenience.
When the official rate is 7.75, accepting 7.00 is a scam.
You’re losing 75 quetzales on every hundred. That’s enough for a shuttle ride from Antigua to the lake. Always know the daily rate before you talk to a vendor. Just type "precio del dólar Guatemala" into your phone. It takes two seconds.
Understanding the Remittance Impact
Guatemala’s economy is heavily propped up by remittances. We’re talking billions of dollars a year. Because of this, the infrastructure for moving 100 dolares a quetzales is incredibly sophisticated but also predatory.

Companies like Western Union and Viamericas make their money on the exchange rate margin, not just the flat fee. They might advertise "Zero Fee" transfers, but then they offer a rate that is 0.30 points below the market. On a $100 transfer, they’re pocketing a couple of dollars in the "hidden" exchange cost. It’s a clever way to charge people without them realizing it.
Real-world math: What does 100 dollars buy you?
Let’s say you successfully swapped your money and you have about 770 quetzales in your pocket. What does that actually get you in 2026?
- A "Menu del Día": In a local spot, maybe 35 to 50 GTQ. You can eat like a king for a week on $100 if you stay away from tourist traps.
- Chicken Bus rides: You could literally travel across half the country. A ride from the capital to Chimaltenango is maybe 15-20 GTQ.
- High-end dinner in Antigua: A nice steak and wine at a place like Hector’s or Isla de Flores will run you about 250-300 GTQ. Your $100 covers two people easily with plenty left over.
- A mid-range Airbnb: Roughly 400-600 GTQ per night.
The quetzal has a lot of purchasing power compared to the dollar if you live like a local. But if you’re buying imported goods—think iPhones, Nike shoes, or even Snickers bars—the price is often higher than in the US because of import taxes.
The psychology of the exchange
There is a weird mental trap when dealing with 100 dolares a quetzales. Because the numbers are larger (770 vs 100), people tend to spend more freely. You see a souvenir for 150 quetzales and think, "Oh, that's cheap!" But that's nearly 20 dollars.
Always divide by 7.5 in your head for a "safe" estimate. It keeps you honest.
Also, watch out for the "Gringo Tax." If a price isn't marked, it’s negotiable. If you pay in dollars directly to a vendor, they will always give you a worse rate than the bank. They have to go stand in that same bank line you’re trying to avoid, so they charge you for the privilege.

Avoid these common mistakes
Don't bring $100 bills from the 1990s or early 2000s (the ones with the small heads). Many places in Guatemala won't accept them because they are easier to counterfeit. You want the "big head" bills, ideally the new "blue" hundreds with the 3D security ribbon.
And never, ever change money with someone who approaches you on the street near the borders. Use an established Casa de Cambio or a bank. The "short count" is a classic scam where they count the money fast, and somehow, your 770 quetzales turns into 600 by the time it hits your hand.
Taking Action
If you need to change 100 dolares a quetzales right now, skip the fancy calculations and follow these steps.
First, check the current rate on a reliable site like the Banco de Guatemala (banguat.gob.gt). This is the gold standard. Look for the "Tipo de Cambio de Referencia."
Second, if you’re in Guatemala, find a Banco Industrial. They usually have the most consistent service. Bring your passport—not a photocopy, the real thing. If you are in the U.S. sending money, use an aggregator like Monito to compare Wise, Remitly, and WorldRemit.
Third, check your bills. If they aren't pristine, don't even bother with the bank. Use them at a large grocery store like La Torre or Walmart; they are sometimes less picky than the bank tellers, though they'll give you change in quetzales at a slightly lower rate.
Lastly, don't over-exchange. You can’t easily change quetzales back to dollars once you leave without losing another 10% in the process. Change what you need, keep the rest in USD. Dollars are the "hard" currency for a reason.
The market moves every day at 6:00 PM when the central bank settles its accounts. If the rate looks particularly good today, grab it. If it looks low, wait until Monday. Markets hate weekends and usually price in a bit of "uncertainty" risk.
