You’ve probably looked at a currency chart for the Hong Kong dollar and wondered if your screen was frozen. It’s flat. Almost perfectly flat. If you are trying to swap hk money to us dollars, you quickly realize this isn't like trading Bitcoin or even the Euro. There is a "ceiling" and a "floor" that basically dictates your financial life in Hong Kong.
Honestly, it’s one of the most successful economic experiments in history, but it feels a bit like magic when you see it in action. Since 1983, the Hong Kong Monetary Authority (HKMA) has kept the rate locked within a tiny window. Specifically, they keep it between 7.75 and 7.85 Hong Kong dollars for every 1 US dollar.
Why? Because stability is the lifeblood of a city that essentially functions as the world's waiting room for trade.
The 7.80 "Magic Number" and How it Works
Most people think a "peg" means the rate is exactly one number. That’s not quite right. It’s more like a corridor. The "Linked Exchange Rate System" (LERS) uses a target of 7.80, but it lets the market wiggle a little.
If the Hong Kong dollar gets too strong—meaning it hits 7.75—the HKMA steps in. They sell HKD and buy USD. This floods the market with local cash and keeps the value from skyrocketing. If it gets too weak and hits 7.85? They do the opposite. They buy back the HKD using their massive pile of US dollar reserves.
This isn't just a suggestion. It’s backed by cold, hard cash. For every single Hong Kong dollar banknote in your wallet, there is an equivalent amount of US dollars sitting in an exchange fund. Three banks—HSBC, Standard Chartered, and Bank of China—actually have to hand over US dollars to the government just to get the "Certificates of Indebtedness" required to print those colorful HKD bills you use at the wet market.

Real-world conversion as of January 2026
If you are standing at a counter right now looking to trade hk money to us dollars, the mid-market rate is hovering right around 0.1282. That means:
- 100 HKD gets you roughly $12.82 USD.
- 1,000 HKD gets you about $128.24 USD.
- To get a clean $100 USD, you'll need about 780 HKD.
But here is the catch. You will almost never get that rate at an airport or a hotel.
Where the Hidden Costs Live
Kinda frustratingly, "stability" for the banks doesn't always mean "cheap" for you. When you're converting hk money to us dollars, you're fighting two different battles: the spread and the fee.
The spread is that annoying gap between the "buy" and "sell" price. Banks in Central or Tsim Sha Tsui might show you a rate that looks close to the official 7.80, but by the time they add their 2% or 3% service margin, you're effectively losing a significant chunk of change.
If you're moving large amounts—say, for a property down payment or moving overseas—a 1% difference isn't just "pocket change." On a million HKD, that’s 10,000 bucks. You've basically paid for someone's business class flight just by clicking "confirm" on a bad bank transfer screen.

Digital-first platforms like Wise, Revolut, or Airwallex usually beat the "Big Three" banks on the rate because they use the mid-market price. They charge a transparent fee instead of hiding the cost inside a skewed exchange rate.
Why This System Still Matters in 2026
There’s always talk about Hong Kong ditching the peg. People have been predicting its death since the 90s. Every time there is a shift in global politics or a hiccup in the US economy, the rumors start swirling again.
But here’s the reality: The peg survived the 1997 Asian Financial Crisis, the 2008 global meltdown, and the volatile start to the 2020s.
By linking hk money to us dollars, Hong Kong essentially imports the monetary policy of the United States. When the Fed raises interest rates in Washington D.C., interest rates in Hong Kong usually follow suit. It’s a trade-off. Hong Kong gives up its ability to set its own interest rates in exchange for a currency that everyone in the world trusts. For a city that handles trillions in trade, that trust is worth more than the freedom to tinker with rates.
The "Interest Rate" Side Effect
Because of this link, if you have a mortgage in Hong Kong, you are deeply tied to the US Federal Reserve. If the US is fighting inflation and hiking rates, your monthly HIBOR-linked payment is probably going up too. It’s a weird feeling to know that a meeting in a boardroom 8,000 miles away determines how much you pay for your flat in Mong Kok, but that’s the price of a stable currency.

Practical Steps for Converting Your Cash
Stop using the airport changers. Seriously. Unless it’s a total emergency, you are basically throwing money into the harbor.
- Check the HIBOR vs. LIBOR/SOFR: If you're a business owner, watch the interest rate gap. When HK rates are higher than US rates, the HKD tends to stay on the "strong side" (closer to 7.75). When they are lower, it drifts toward 7.85.
- Use Multi-Currency Accounts: If you live between the two regions, accounts like HSBC Expat or digital equivalents allow you to hold both currencies. Wait for the rate to hit the "strong side" (7.75-7.77) to buy your USD.
- Small amounts? Use an ATM: Usually, pulling USD out of an ATM in the States using a Hong Kong-based card gives a better rate than a physical money changer, provided your bank doesn't have a predatory foreign transaction fee.
- Large Transfers: Use a specialist FX broker. Don't just use the "Global Transfer" button on your banking app without comparing it to a third-party service first.
Moving hk money to us dollars is arguably one of the most predictable currency trades you can make. It’s a boring market, but in the world of finance, boring is usually a very good thing. It means you don't wake up to find your savings worth 20% less than they were yesterday.
Keep an eye on the 7.75 and 7.85 boundaries. As long as those hold, your planning remains simple. Just watch out for the fees—that's where the real "exchange rate" happens.
To maximize your value, always compare the "all-in" cost (rate + fee) rather than just looking at the big numbers on the board. Start by looking at the current HKMA aggregate balance; a shrinking balance usually signals that the HKD is under pressure and hitting that 7.85 weak-side limit.
