What is CHATS? How long does it take? Popular choices & fees for instant foreign currency transfers in Hong Kong

In Hong Kong, when you need to make a large transfer or a local foreign currency interbank transfer, such as moving USD from HSBC to Standard Chartered, banks typically recommend using an express transfer. The underlying system for this is CHATS. So, what exactly is CHATS? How does it differ from our commonly used FPS (Faster Payment System) or SWIFT wire transfers? This article will break down all these questions for you and reveal the foreign currency transfer fees of major banks, helping you manage your funds wisely.

What is CHATS? Understanding how express transfers work

CHATS stands for "Clearing House Automated Transfer System." It is Hong Kong's interbank real-time payment settlement system, specifically designed for interbank transfers in HKD, USD, EUR, and RMB.

When you select an express transfer or local interbank transfer online, it's typically processed via CHATS. Its key feature is the "Real-Time Gross Settlement" (RTGS) model, where funds are processed instantly, offering high security and settlement finality. This makes it ideal for large commercial transactions or significant payments like down payments for property.

Why choose CHATS for local foreign currency transfers? Comparison with FPS/SWIFT

CHATS vs SWIFT

If you're transferring foreign currency to another bank within Hong Kong, you should choose CHATS, not SWIFT.

• CHATS: Exclusively for local interbank transfers. Since it doesn't involve overseas correspondent banks, CHATS transfers are usually faster than SWIFT (can be settled the same day), and foreign currency transfer fees are lower than SWIFT.

• SWIFT: Primarily used for cross-border remittances (e.g., sending money to the U.S.). If SWIFT is mistakenly used for a local transfer, it will take longer and incur expensive wire transfer fees.

CHATS vs FPS

• FPS (Faster Payment System): Its advantage lies in 24/7 operation and zero fees, but its drawbacks include typical daily transfer limits and primary support for HKD and RMB, not USD or EUR.

• CHATS: Its advantage lies in supporting 4 major currencies (including USD and EUR) and often having no specific transaction amount limit, making it suitable for large local foreign currency interbank transfers. However, its drawbacks are that it only operates during bank business hours and usually charges fees.

How long does CHATS take? Be aware of cutoff times

CHATS' main selling point is instant settlement. As long as you submit the instruction before the bank's cutoff time, the recipient can usually receive the funds the same day.

If you miss the cutoff time, or make a CHATS transfer on weekends or public holidays, the instruction will be processed on the next business day. Therefore, it's crucial to allow ample time for urgent remittances. Also, note that cutoff times vary by bank and currency; typically, HKD is 4:30–5:30 PM, while USD or EUR might be earlier, around 3:30 PM.

Which banks offer fee-free CHATS foreign currency transfers?

Foreign currency transfer fees vary depending on the bank, customer tier, and transfer channel.

CHATS Online Banking Fee Comparison

Using online banking for CHATS is the most cost-effective option. Most banks (e.g., Citibank, Standard Chartered, HSBC) waive online CHATS foreign currency interbank transfer fees[1], while some banks only offer fee waivers for specific customer tiers (e.g., Premier Banking). Regular accounts may still incur fees. Achieve zero-cost transfers, but be mindful of online banking's daily transfer limits.

CHATS Branch Counter Fee Comparison

If you visit a branch counter in person, banks typically charge a fee ranging from HK$70 to HK$250[2]. Therefore, it's recommended to use online banking or a mobile app.

Important Notes for CHATS Transfers

Be aware of the currencies supported by your bank

While Hong Kong's CHATS system supports HKD, USD, EUR, and RMB, not every bank offers CHATS services for all currencies. Before making a foreign currency transfer, it's advisable to confirm if your bank supports local settlement for that specific currency.

Plan transfers in advance based on account limits

Even though the CHATS system itself is suitable for large transactions, you need to be aware of your account's daily transfer limits. Online banking usually has a lower default limit. Therefore, remember to increase your limit before making a large CHATS transfer.

Convert foreign currency before making a CHATS transfer

CHATS is primarily for "remittance," not "exchange." If you want to transfer USD, your USD account must have sufficient USD balance. Otherwise, the bank will first convert HKD to foreign currency at the day's (usually less favorable) exchange rate, which may result in exchange rate losses.

Some banks may process CHATS under the name of wire transfer

Some bank's online banking interfaces might not explicitly label it as "CHATS" but categorize it as "Local Wire Transfer" or "Express Transfer." As long as the receiving bank is in Hong Kong, the system will usually automatically process it via CHATS.
