USD/HKD — US Dollar to Hong Kong Dollar
USD/HKD measures how many Hong Kong dollars one US dollar buys. Unlike most currency pairs, it is not a freely floating market rate — it is anchored by one of the world's longest-running currency pegs.
Since 1983, the Hong Kong dollar has operated under the Linked Exchange Rate System, which holds USD/HKD within a narrow 7.75–7.85 band around a 7.80 convertibility rate. The Hong Kong Monetary Authority (HKMA) defends this band through convertibility undertakings, buying or selling Hong Kong dollars at the band's edges to keep the rate inside it.
Because the peg does the heavy lifting, day-to-day movement in USD/HKD is driven mainly by the gap between HIBOR (Hong Kong interbank rates) and US interest rates, which pushes the spot rate toward the strong or weak side of the band, rather than by the broader macro drivers that move a floating currency.
This page shows an indicative mid-market USD/HKD rate that can update intraday through the trading week, reflecting the pair's very tight trading range. Every API response carries a source and market_session field, so you can tell whether a given quote was a live tick or a daily fix. Rates are indicative only, not for settlement or regulated trading.
Frequently asked questions
- What does USD/HKD measure?
- USD/HKD states how many Hong Kong dollars you receive for one US dollar. Because of the currency peg, this number stays within a narrow band rather than fluctuating freely — a rate of 7.80 means one dollar buys 7.80 HKD, close to the midpoint of that band.
- Is USD/HKD a live rate on exchangerate.dev?
- USD/HKD is served as an indicative mid-market rate that can update intraday through the trading week. Check the source and market_session fields on each API response to see whether a specific quote was a live tick or a daily reference fix.
- How do I get the USD/HKD rate via the API?
- GET /v1/latest/USD?symbols=HKD returns the indicative rate along with source, market_session, and timestamp. The reverse (HKD as base) is also supported. The free tier covers it, no credit card required.
- Why is USD/HKD so stable compared to other pairs?
- Hong Kong operates a currency board system, the Linked Exchange Rate System, that has held USD/HKD inside a 7.75–7.85 band since 1983. This is a policy commitment, not a market outcome, so the rate does not move the way a freely floating currency would.
- What is the Hong Kong Monetary Authority's role in the peg?
- The HKMA defends the band through convertibility undertakings — standing commitments to buy or sell Hong Kong dollars at the strong and weak edges of the 7.75–7.85 range, which keeps market forces from pushing the rate outside it.
- Why does USD/HKD still move at all if it's pegged?
- Within the narrow band, the rate drifts based on the spread between HIBOR and comparable US dollar interest rates. A wider HIBOR-US gap tends to push the rate toward one edge of the band as arbitrage flows respond to the rate differential.
- Is USD/HKD suitable for settlement or trading decisions?
- No. exchangerate.dev provides indicative rates for reference and informational use only — not for settlement, regulated trading, or as a source-of-record price, even for a pegged currency.
