If you’re landing in Lima or just trying to move some money across borders, you’ve probably stared at the 1 USD to PEN exchange rate and wondered if you're getting fleeced. It's a fair question. Honestly, the Peruvian Sol is a bit of an outlier in Latin America. While other currencies in the region often swing wildly like a pendulum in a storm, the Sol—fondly called the "Machengo" by some old-school traders—is famously stable. But don't let that "stability" lull you into a false sense of security.
As of January 17, 2026, the interbank exchange rate is hovering around 3.36. That’s the "pure" price, the one you see on Google or Bloomberg. If you walk into a bank or a street-side cambista, you aren't getting that 3.36. You're getting whatever they decide to give you after they take their cut.
Navigating the 1 USD to PEN exchange rate isn't just about math; it's about knowing where the trapdoors are.
Why the Sol Is Acting This Way Right Now
You’ve got to look at the Banco Central de Reserva del Perú (BCRP) to understand why your dollar buys what it does. Just a few days ago, on January 8, the BCRP kept its reference interest rate steady at 4.25%. They've been holding this line for four months now. Why? Because inflation in Peru is actually behaving itself, sitting around 1.5% to 2.1%—which is basically a miracle compared to some of its neighbors.
But there’s a shadow on the horizon.
Peru is heading into general elections in April 2026. Usually, when elections loom, people get nervous. Nervous people buy dollars. When everyone buys dollars, the price of the dollar goes up and your Sol gets weaker. Right now, the market is in a "wait and see" mode. Investors are watching the polls, but for the moment, the massive copper exports and the full-scale operation of the Chancay Port are keeping the Sol anchored. It’s a tug-of-war between political "noise" and solid copper cash.

Don't just walk into the first place with a "Cambio" sign. You'll regret it.
The Airport Trap
If you change your money at Jorge Chávez International Airport, you are essentially paying a "convenience tax" that can be as high as 10%. It’s predatory, frankly. Use the airport booths to change $20 so you can pay for a bus or a licensed taxi (like Taxi Green or Directo), then stop.
The Street Cambistas
You’ll see them in Miraflores, wearing those bright vests with the "$" and "S/" signs. They are a Peruvian institution. Surprisingly, they often offer better rates than the big banks. It’s weird, I know. However, if you aren't fluent in Spanish and you don't know how to spot a fake bill (look for the watermark and the color-shifting ink on the "20", "50", or "100"), stick to the formal houses.
Casas de Cambio
This is the sweet spot. Look for places like Casa de Cambio Rey's on Calle Schell in Miraflores or the clusters around Jirón de la Unión in the center. They are registered with the SBS (Superintendency of Banking and Insurance), which means they’re legit. They usually display two numbers:
- Compra (Buy): What they pay you for your dollar.
- Venta (Sell): What they charge you to get a dollar.
The "spread"—the gap between these two—tells you how much they're skimming. If the gap is more than 0.05 or 0.06 Soles, you’re in the wrong shop.

Digital Is Taking Over (and Saving You Money)
If you have a Peruvian bank account, or you're staying long-term, stop using physical cash for big exchanges. Apps like Rextie, TKambio, and Securex have changed the game. They use the interbank rate and charge a tiny, transparent margin.
For travelers, Wise is often the gold standard. They use the mid-market rate—that 3.36 we talked about—and just charge a small fee. It almost always beats a physical exchange house. Just make sure when you use an ATM (like GlobalNet or BCP), you always decline the "Dynamic Currency Conversion." If the ATM asks if you want them to do the conversion for you, say NO. Let your own bank handle the math. If you say yes, the ATM owner sets the rate, and it’s never in your favor.
Common Mistakes That Kill Your Rate
People think a dollar is a dollar. In Peru, it’s not.
If your 20-dollar bill has a tiny 2-millimeter tear on the edge, or if it’s written on, or even if it just looks too "tired," many places will refuse it. Or worse, they’ll offer you a "damaged bill rate" which is basically highway robbery. Keep your cash crisp.
Also, watch out for the $100 bills from the "CB" series. There was a famous batch of high-quality counterfeits years ago, and some older cambistas still get spooked by them.
What to Expect for the Rest of 2026
The consensus from analysts at BBVA and Scotiabank is that the 1 USD to PEN exchange rate will likely stay in the 3.30 to 3.45 range through the first half of the year.

The big "if" is the election. If a radical candidate starts gaining steam in the polls, expect a spike toward 3.50 or higher. If a moderate, pro-market candidate looks like a lock, the Sol might actually get stronger.
Peru has massive "International Net Reserves"—basically a giant piggy bank the BCRP uses to buy or sell dollars to keep the rate from jumping too fast. They don't fight the trend, but they smooth out the bumps. It's why the Sol doesn't crash like the Argentine Peso or the Venezuelan Bolivar.
Actionable Steps for Your Money
- Check the BCRP site: Before you go out, check the official "Tipo de Cambio" on the Central Bank's website. Use that as your baseline.
- Download a Comparison App: If you're in Peru, use the "Cuantoestaeldolar" website. It shows you the real-time rates of all the major digital exchange houses and the street rate in different districts.
- Avoid Banks for Cash: Ironically, banks like BCP or BBVA often have the worst rates for physical cash. They don't really want your paper dollars; they want your digital business.
- Use Credit Cards Wisely: Most places in Lima and Cusco take cards. Use a card with no foreign transaction fees (like a Chase Sapphire or a Capital One Venture). You'll get the Visa/Mastercard wholesale rate, which is almost impossible to beat with cash.
- Small Bills for Small Towns: If you’re heading to the Amazon or remote parts of the Sacred Valley, change your money in Lima or Cusco first. Small-town rates are terrible, and they often won't have change for a 100-sol note.
The 1 USD to PEN exchange rate is a moving target, but it's one of the most predictable ones in the region. Pay attention to the spread, keep your bills crisp, and never—ever—change more than a "coffee and taxi" amount at the airport.
Stay updated on the BCRP's monthly policy meetings, as any hint of a rate cut could push the dollar slightly higher. For now, 3.36 is your North Star. Keep it in mind, but expect to walk away with something closer to 3.34 after the house takes its piece.
