If you’re landing at Chek Lap Kok and expecting to use the Chinese Yuan just because Hong Kong is part of China, you’re in for a bit of a surprise.
The money situation here is unique. Honestly, it’s one of the few places where the "One Country, Two Systems" principle is literally in your wallet. The official currency in Hong Kong is the Hong Kong Dollar (HKD). You'll see it written as $ or HK$ to keep it from getting mixed up with the US version.
But it’s not just about the name. The way this money works—who prints it, how much it’s worth, and why the notes look so different from each other—is a whole vibe.
The Weird World of Note-Issuing Banks
Most countries have one central bank that prints all the cash. Hong Kong likes to do things differently. Here, three different commercial banks actually print the money.
If you withdraw 500 bucks, you might get a note from HSBC, one from Standard Chartered, or one from the Bank of China. They all have different designs. One might have a lion, another a skyscraper. It can be super confusing for first-timers who think they’ve been handed Monopoly money. Don't worry, they’re all legit.

The only exception? The $10 note. The Hong Kong Government handles that one directly. It’s usually a bright purple, plastic-feeling (polymer) note that’s pretty much indestructible.
Current Denominations in Your Pocket
- Coins: 10c, 20c, 50c (the tiny ones), and $1, $2, $5, $10.
- Banknotes: $20, $50, $100, $500, and the "big boy" $1,000.
A quick tip: many small "dai pai dong" (food stalls) or tiny shops in Mong Kok won't take $1,000 notes. They’re scared of counterfeits, or they just don't have the change. Try to break those at a 7-Eleven or a supermarket.
Why the HKD is Glued to the US Dollar
Since 1983, the Hong Kong Dollar has been "pegged" to the US Dollar. This is called the Linked Exchange Rate System. Basically, the Hong Kong Monetary Authority (HKMA) keeps the rate within a tight window of $7.75 to $7.85 HKD for every $1 USD.
Why? Stability. Because Hong Kong is a massive global financial hub, they want to make sure the currency doesn't go on a rollercoaster every time there's a bit of market drama.

As of early 2026, the HKMA is sitting on about US$427.9 billion in foreign reserves. That’s a massive war chest used specifically to make sure that peg stays solid. If the HKD gets too weak, they buy it back. If it gets too strong, they sell. It’s a machine that hasn't broken in over 40 years.
Cash is Still King (Sorta)
Hong Kong is futuristic, but it's also deeply traditional. You can pay for a luxury watch with your phone, but you’ll need coins for a vintage tram ride.
The Octopus Card: The Real Currency
If you’re in Hong Kong for more than two hours, get an Octopus Card. It started as a bus pass in the 90s, but now it’s basically a shadow currency. You can use it at:
- Vending machines and laundromats.
- Basically every convenience store (7-Eleven, Circle K).
- Fast food joints like Maxim's or Café de Coral.
- Supermarkets.
You just tap and go. No fuss.

What about the e-HKD?
You might have heard whispers about a digital currency. The HKMA has been testing an e-HKD. By the first half of 2026, they're finishing up the legal and technical groundwork. But don't expect to be using it as a tourist just yet. For now, they’re focusing more on "wholesale" uses—big bank-to-bank stuff—rather than a retail app for your morning pineapple bun.
Can I use Chinese Yuan (RMB) in Hong Kong?
Kinda. Some big tourist shops and pharmacies in Tsim Sha Tsui will take it, but the exchange rate they give you is usually terrible. They’ll often do a 1:1 rate just to keep it simple for them, which means you’re overpaying by a lot.
Stick to HKD. Your wallet will thank you.
Smart Money Moves for Travelers
If you're heading over soon, don't change all your money at the airport. The rates there are notoriously bad. Instead, use an ATM. Most ATMs in Hong Kong accept international cards (Visa, Mastercard, Plus, Cirrus).
Watch out for DCC (Dynamic Currency Conversion). When an ATM or a card reader asks if you want to be charged in your "home currency" or "local currency," always pick local (HKD). If you pick your home currency, the bank chooses the rate, and it’s never in your favor.
Actionable Next Steps:
- Check your bank's international fees. If they charge 3% per transaction, grab a travel-friendly card like Wise or Revolut before you fly.
- Download "HKD" on a currency converter app. Since the rate is pegged, the math is usually $7.8, which is roughly 8-to-1. It makes mental math easier.
- Keep $200-$300 HKD in cash. Even in 2026, those legendary hole-in-the-wall dim sum spots in Sham Shui Po are often cash-only.
- Get the Octopus App. You can now top up your physical or mobile Octopus card directly through your phone if you have a compatible NFC device.
Hong Kong’s money is a reflection of the city itself: a mix of old-school cash reliance and high-tech digital systems, all backed by one of the most stable financial pegs in the world.
