Currency & denominations
The Hong Kong dollar (HK$) is issued as notes of 10, 20, 50, 100, 500, and 1,000, plus coins of 10, 20, and 50 cents and 1, 2, 5, and 10 dollars. Notably, three banks (HSBC, Standard Chartered, and Bank of China) issue notes, so designs differ for the same value but all are valid. Keep smaller notes for taxis and local shops.
Cash vs card
Cards are widely accepted at malls, restaurants, hotels, and chains, but cash is still needed for taxis, wet markets, small local eateries (dai pai dong), and minibuses. The Octopus card is the dominant way to pay for transport and small purchases at convenience stores and many shops. Carry both some cash and an Octopus card for smooth daily spending.
Where to get the best exchange rates
Licensed money changers in areas like Tsim Sha Tsui and Central often offer better rates than banks and hotels for cash, with no commission at reputable ones. Compare a couple of changers and confirm the net amount before handing over money. Bank ATMs and card payments also give fair, competitive rates.
Avoid the airport exchange trap
Currency counters at Hong Kong International Airport give poor rates with wide margins. Change only enough for transport into the city, then use a licensed changer in town or an ATM for the rest. You can also buy and top up an Octopus card at the airport to cover the train and onward travel.
Using ATMs
ATMs are plentiful; those operated by HSBC, Hang Seng, Standard Chartered, and Bank of China reliably accept foreign cards. Look for Plus or Cirrus logos for your network. Choose to be charged in Hong Kong dollars rather than your home currency to avoid dynamic currency conversion markups.
Tipping culture
Tipping is modest in Hong Kong. Many restaurants add a 10% service charge to the bill, in which case extra tipping is optional, though locals often leave the small change. For taxis, rounding up the fare is common, and a small tip for hotel porters is appreciated.
Common money pitfalls & scams
Be aware the three note-issuing banks produce different-looking notes; all are legitimate, so don't reject unfamiliar designs. Watch for dynamic currency conversion at terminals and ATMs and always choose Hong Kong dollars. Use only licensed money changers and confirm the rate and total before exchanging to avoid bait-and-switch tactics.
How much cash should you bring
A moderate amount of cash plus an Octopus card covers most needs, with cards handling larger purchases. Keeping a few hundred Hong Kong dollars for taxis, markets, and small eateries is practical. Top up from bank ATMs and reload your Octopus card with cash as you go.
