USD/HKD Exchange Rate History
A decade of US Dollar–Hong Kong Dollar movements, with the events that drove them.
USD/HKD 10-year snapshot
USD/HKD currently sits roughly 83% through its 10-year range — near the upper end, with the rate at decade-high levels.
The last decade in USD/HKD
USD/HKD is the most boring major-currency pair on record — by design. The Hong Kong Dollar has been pegged to USD via the Linked Exchange Rate System since 1983, trading exclusively within a 7.75–7.85 band. The HKMA defends both sides of the band with aggressive intervention. Over 2016–2026, USD/HKD has spent the entire period within 0.6% of its 7.80 midpoint — making it the least volatile major-currency pair in the world. Multiple speculative attacks have tested the peg but none have come close to breaking it.
Long-term trend
Remarkably stable since 1983 — over 40 years within the same trading band. The Linked Exchange Rate System has survived: the 1997 Asian Financial Crisis (when Thailand, South Korea, Indonesia, Malaysia all broke their pegs), the 2003 SARS epidemic, the 2008 Global Financial Crisis, the 2014 Occupy Central protests, the 2019-2020 social unrest, COVID-19, and the 2022 Fed tightening cycle. HKMA holds over $400B in foreign reserves — roughly twice Hong Kong's monetary base — making the peg one of the best-defended currency arrangements in the world.
Key events
HKMA defends weak side as Fed tightens
As the Fed began its first post-crisis rate hikes, USD/HKD pressed toward the 7.85 weak-side band. HKMA intervened by buying HKD to defend the band — the first major test of the post-2008 peg.
USD/HKD traded near 7.7500 (strong side) early 2015; drifted to 7.85 weak side by 2018.
HKMA defends band aggressively
USD/HKD repeatedly hit the 7.85 weak-side limit as the US-Hong Kong rate differential widened. HKMA bought billions in HKD over April-July 2018 to defend the band, draining the Aggregate Balance from HK$180B to HK$76B.
USD/HKD held near 7.85 weak side for months in 2018.
Social unrest tests peg confidence
The pro-democracy protests that began June 2019 created speculation that capital flight could test the peg. Bill Ackman (Pershing Square) publicly disclosed a short position on HKD. HKMA reassured markets the peg was unbreakable; no test occurred.
USD/HKD held a tight 7.82-7.85 range through the unrest.
HKMA defends weak side again as Fed hikes
The 2022 Fed tightening cycle widened the HIBOR-SOFR rate differential, pushing USD/HKD to the 7.85 weak-side limit. HKMA bought HK$40B+ in HKD over May-July 2022 to defend the band — second-largest intervention since 2003.
USD/HKD pressed against 7.85 from May-October 2022.
Fed cuts; USD/HKD drifts toward strong side
As the Fed began rate-cutting cycle in September 2024, the HIBOR-SOFR differential narrowed and reversed. USD/HKD drifted toward the 7.75 strong-side limit for the first time since 2020.
USD/HKD fell from 7.81 (mid-2024) to 7.76 (December 2024).
Practical takeaway
For travelers, money senders, or businesses dealing with HKD, the peg means timing doesn't matter — USD/HKD will be within 0.6% of 7.80 every day for the foreseeable future. Focus entirely on minimizing conversion fees rather than chasing rate movements that don't exist. The HKMA peg defense is one of the strongest in the world; no credible analyst expects it to break in the next decade. Wise, Revolut, or any major fee-free debit card delivers near-mid-market rates on USD-HKD conversions.

Frequently asked questions
When was the HKD peg established?
October 17, 1983 — in response to a confidence crisis as Hong Kong's 1997 handover to China approached. The peg fixed HKD at HK$7.80 per USD with HKMA committed to defend the rate. In 2005, the peg was modified to a band of 7.75-7.85 with HKMA committed to defending both sides. The peg has held for over 40 years through every major crisis.
Will the HKD peg ever break?
No credible analyst forecasts a peg break in the foreseeable future. HKMA holds over $400B in foreign reserves — roughly twice Hong Kong's monetary base — meaning HKMA has more than enough firepower to defend the peg indefinitely. The political question of whether China would ALLOW a change is more meaningful than the financial one. Beijing's stated position is full support for the peg.
What is the HKMA Aggregate Balance?
The Aggregate Balance is the total amount of HKD that commercial banks hold on deposit at HKMA. It measures HKD liquidity in the banking system. When HKMA defends the 7.85 weak side, it buys HKD (selling USD reserves), withdrawing HKD from the system — reducing the Aggregate Balance and pushing HIBOR (Hong Kong interbank rate) higher. This makes shorting HKD expensive, forcing speculators to close positions and pushing USD/HKD back within the band.
