Hong Kong Currency & Money Guide: Exchange, Cards, and Tips

Hong Kong uses the Hong Kong dollar (HKD or HK$), and cards are widely accepted, but cash and an Octopus card remain useful for markets, small eateries, transport, and taxis. As a guide, S$1 was approximately HK$6.13 on 23 October 2026, although live rates change constantly; check your card provider before converting. Hong Kong generally has no compulsory tipping culture, so round up or leave a small amount only when service is especially good. For a smooth Hong Kong trip, carry a small cash reserve, use a bank ATM, decline unnecessary currency conversion, and track spending in multiple currencies with the Hello app.

The local currency is the Hong Kong dollar, divided into 100 cents, and travellers should budget in HKD rather than relying on Singapore-dollar mental conversions. On 23 October 2026, the SGD/HKD cross-rate was around S$1 = HK$6.13, while 1 HKD was approximately S$0.163; treat these as indicative mid-market rates, not guaranteed cash-exchange rates. A restaurant bill of HK$200 therefore works out to roughly S$32.60 before card fees or exchange-rate margins. Hong Kong banknotes commonly come in HK$20, HK$50, HK$100, HK$500, and HK$1,000 denominations, while coins cover smaller fares and purchases. HK$1,000 notes can be inconvenient at market stalls or small restaurants, so request smaller notes when changing cash. The Hong Kong dollar is pegged to the US dollar within a narrow range, which helps keep its value relatively stable but does not eliminate daily SGD/HKD fluctuations. Compare the live rate in your banking app with the quoted cash rate before exchanging. Hello’s multi-currency expense tracker can automatically convert HKD spending into SGD, making it easier to see the real cost of meals, transport, and shopping.

The best Hong Kong exchange rate usually comes from a regulated bank, reputable money changer, or fee-transparent card rather than an airport counter, and travellers should compare the final amount received before handing over cash. Airport exchange desks are convenient after landing but often include a wider spread, so exchange only enough for immediate transport and essentials. In the city, compare several licensed counters in busy commercial areas such as Central, Tsim Sha Tsui, Mong Kok, and Causeway Bay; never choose solely because a sign advertises zero commission. Ask how many Hong Kong dollars you will receive for your exact Singapore-dollar amount after every fee. Keep the receipt until you have counted the notes. Avoid informal street exchanges and inspect banknotes before leaving the counter. A practical arrival plan is to exchange a modest amount, use a bank ATM for additional cash if needed, and pay larger hotel or restaurant bills by card. When a terminal asks whether to charge in SGD or HKD, choose HKD: the SGD option is dynamic currency conversion and commonly uses a less favourable rate. Do not exchange all your leftover HKD at the airport unless convenience matters more than price.

Visa and Mastercard are accepted at most hotels, shopping malls, international restaurants, supermarkets, attractions, and chain cafés, while contactless payment is common; however, small local businesses may still prefer cash or Octopus. The Octopus card remains one of the most practical ways to pay for MTR journeys, buses, trams, ferries, convenience-store purchases, and selected retailers. Tourist Octopus options include a HK$39 card without stored value, while an adult on-loan version lists a HK$50 deposit and HK$150 initial stored value. An Airport Express single journey between Hong Kong Station and the airport is about HK$120 with Octopus, and typical MTR journeys cost roughly HK$5–15. | Payment method | Best for | Watch-outs | |---|---|---| | Visa or Mastercard | Hotels, malls, restaurants | Foreign transaction fees and minimum spends | | Contactless card or phone wallet | Fast retail and transport payments where supported | Carry a backup card and battery | | Octopus | MTR, buses, trams, ferries, convenience stores | Refund or handling conditions may apply | | WeChat Pay or AlipayHK | Participating local merchants | Setup, verification, and foreign-card compatibility vary | | Cash | Markets, small eateries, taxis, emergencies | Avoid carrying large amounts | WeChat Pay and AlipayHK are popular locally, but visitors should not assume every overseas account or card will work everywhere. Keep at least two payment options available.

ATMs are easy to find in Hong Kong, especially at the airport, MTR stations, shopping centres, banks, and convenience-store locations, but the cheapest withdrawal depends on both the local operator and your home bank. Use a machine attached to a recognised bank, check the displayed fee, and decline conversion to SGD so your own bank or card network sets the exchange rate. Before travelling, tell your bank about overseas use, confirm your daily withdrawal limit, and carry a second card stored separately. Choose smaller withdrawals rather than taking out a large amount at once, particularly if your accommodation has no safe. Hong Kong is generally safe, but money scams still reward caution. Be suspicious of unofficial currency exchangers, pressure to sign receipts, altered prices at tourist-focused shops, and card terminals that are handed over without showing the amount. Count cash immediately after an exchange and check restaurant bills for duplicate items or unexplained service charges. Never share an ATM PIN, and shield the keypad. Keep receipts for card disputes. A useful emergency reserve is around HK$500–1,000 in separate notes, enough for transport, food, and a short-term payment failure without carrying your entire travel budget.

Hong Kong tipping is modest rather than compulsory: restaurants may add a 10% service charge, so check the bill before leaving anything extra. If no service charge appears, rounding up or adding around 5–10% for warm, attentive service is appreciated but not required; local cafés and taxis generally do not expect a large tip. Hotels may receive a small HK$10–20 tip for helpful luggage or room service, while tour guides can be tipped at your discretion. For cost planning in 2026, a cha chaan teng breakfast may cost HK$35–60, a casual local lunch HK$50–80, and a straightforward dinner HK$80–150. A typical sightseeing day using the MTR can cost around HK$30–60, while the Star Ferry is roughly HK$4–6.50 depending on deck, weekday, weekend, and public-holiday pricing. Travellers can save by eating at cooked-food centres, dai pai dong-style restaurants, bakeries, and neighbourhood noodle shops instead of hotel restaurants. Use the MTR and trams, compare attraction bundles, and carry a reusable bottle where practical. The Hello app can scan receipts in different languages and currencies, categorise spending automatically, and split shared bills with friends using live multi-currency conversion.

The short answers are: bring a small amount of HKD, rely mainly on cards and Octopus, pay in HKD rather than SGD, and tip only when the bill does not already include service. Should I bring Singapore dollars to Hong Kong? Bring some only as a backup; exchanging a small amount after arrival or withdrawing HKD from a bank ATM is usually more practical than carrying a large cash wad. Is cash needed in Hong Kong? Yes, for wet markets, tiny restaurants, some taxis, and occasional minimum-spend rules, although cards cover most major purchases. Can I use contactless payment? Often yes at modern retailers and selected transport or ticketing points, but acceptance is not universal, so keep an Octopus card or cash backup. Do I need to tip taxi drivers? No; rounding up is optional. How much cash should I carry? HK$300–500 for a normal day is a sensible starting point, with more if visiting markets or rural areas. What is the safest way to pay? Use a bank card or phone wallet, select HKD at the terminal, and verify the amount before confirming.
