How to buy Hong Kong stocks in the UK

UK investors and Hong Kong stocks

The Hong Kong Stock Exchange (HKEX) is the world's sixth largest exchange by market capitalisation and one of the most internationally accessible gateways to Chinese and Asian equities. For UK investors looking to buy Hong Kong stock, it offers exposure to global technology companies including Tencent and Xiaomi, major financial institutions, energy companies, and a rapidly expanding pool of dual-listed mainland Chinese firms.

Hong Kong reclaimed the top global IPO ranking in 2025 for the first time since 2019, with total proceeds on HKEX reaching HK$280 billion, up 218% year-on-year and the second-highest level in nearly five years. With over 300 active IPO applications in the pipeline at the start of 2026, the exchange is well positioned for continued momentum.

About the Hong Kong Stock Exchange

The Stock Exchange of Hong Kong (SEHK) is operated by Hong Kong Exchanges and Clearing Limited (HKEX), which also operates the London Metal Exchange. The exchange has two boards: the Main Board for established companies meeting minimum financial requirements, and the Growth Enterprise Market (GEM) for smaller, growth-oriented companies.

Hong Kong's unique position as a special administrative region of China under the 'one country, two systems' framework has historically made it the preferred listing venue for large mainland Chinese companies seeking international capital. 

This has given the exchange a distinctive character: many of its largest companies are headquartered in mainland China but listed in Hong Kong, giving international investors access to Chinese corporate earnings. However, many analysts believe that rules and regulations could change, meaning investors could be accepting a higher degree of risk in exchange for potentially large capital growth.

The exchange operates from Monday to Friday, 9:30am to 4:00pm Hong Kong time (HKT), which is UTC+8. This means the morning session runs from 1:30am to 8:00am UK time in winter, and 2:30am to 9:00am in summer, making active trading during market hours impractical for most UK-based investors. Most UK investors therefore place orders that execute at the open or use limit orders.

The Hang Seng Index

The Hang Seng Index (HSI) is Hong Kong's primary benchmark, maintained by Hang Seng Indexes Company Limited, a subsidiary of Hang Seng Bank. It currently comprises 88 constituent companies representing approximately 58% of the total market capitalisation of the Hong Kong Stock Exchange. The index was first published on 24 November 1969.

The largest constituents by weighting as of April 2026 are HSBC Holdings (8.26%), Alibaba (7.48%), Tencent (7.33%), AIA Group (5.51%), China Construction Bank (5.20%), ICBC (3.57%), Xiaomi (3.26%), China Mobile (3.24%), HKEX (3.06%) and CNOOC (2.82%). The index is dominated by financials, technology and consumer discretionary names.

The Hang Seng was trading around 24,249 on 12 June 2026, having reached a high of over 24,000 in the first half of 2026 before pulling back on technology sector weakness and Middle East geopolitical tensions. Analysts from institutions including DBS have set year-end targets in the 28,000-31,000 range.

How to buy Hong Kong stock in the U

Buying Hong Kong stocks in the UK follows the same general process as buying any international shares, with a few HKEX-specific points to note:

1. Choose a UK brokerage platform that provides access to HKEX. Not all UK platforms offer Hong Kong stocks directly, so check availability before opening an account. We provide access to HKEX-listed shares through our share dealing account.
2. Open a share dealing account or general investment account. Hong Kong stocks listed only on HKEX are generally not ISA-eligible, since HKEX is not a recognised exchange under current UK ISA rules. However, some companies are dual-listed on US exchanges, such as Alibaba (NYSE: BABA) and HSBC (LSE: HSBA), which can be held in an ISA via those listings.
3. Search for the stock by its HKEX ticker. All HKEX Main Board stocks have four-digit numeric codes, for example Tencent is 0700, AIA is 1299 and HSBC is 0005. On data platforms these often appear with a .HK suffix, for example 0700.HK.
4. Place your order in Hong Kong dollars (HKD). The trade will involve a currency conversion from GBP to HKD. Be aware of the FX conversion fee charged by your platform, which typically ranges from 0.25% to 1.5%.
5. Monitor the position in GBP terms. Your return is affected not only by the stock's performance in HKD but also by movements in the GBP/HKD exchange rate. Managing this exposure is particularly important for larger positions. The tools available for protecting a portfolio from currency risk range from currency-hedged ETFs to forward contracts, depending on the scale of your exposure.
6. Consider tax obligations. Dividends from Hong Kong stocks held outside an ISA or SIPP are subject to UK income tax above the £500 dividend allowance. Capital gains above the £3,000 annual allowance are subject to UK CGT. See the tax section below.

Trading Hong Kong stocks with CFDs and spread bets

For shorter-term traders, we offer CFDs and spread bets on a wide range of HKEX-listed stocks and on the Hang Seng Index itself. These instruments allow leveraged exposure to price movements in both directions without taking ownership of the underlying shares.

Spread bets on Hong Kong stocks and the Hang Seng Index are quoted in GBP and denominated in sterling points, which removes the direct currency conversion step for UK traders. CFDs are quoted in the local currency of the underlying asset.

Leverage magnifies both gains and losses. 68% of retail investor accounts lose money when trading spread bets and CFDs with IG. These products are not suitable for all investors and are not appropriate for long-term investment.

Costs of buying Hong Kong stocks from the UK

Unlike UK shares, there is no UK stamp duty reserve tax (SDRT) on purchases of Hong Kong stocks, since SDRT only applies to UK-listed securities. The Hong Kong stamp duty of 0.10% applies to both the buyer and the seller and is collected automatically.

Currency: GBP/HKD

The Hong Kong dollar is pegged to the US dollar under a linked exchange rate system maintained by the Hong Kong Monetary Authority (HKMA) since 1983. The peg is maintained within a narrow band of HK$7.75 to HK$7.85 per US dollar. This means GBP/HKD movements are effectively driven by GBP/USD movements, rather than by Hong Kong's own economic conditions.

In 2025-26, GBP/HKD has broadly reflected sterling's strength against the dollar, trading in an approximate range of 9.80 to 10.40 HKD per pound. For UK investors in HKEX stocks, currency risk management is therefore primarily a question of sterling/dollar dynamics rather than Hong Kong-specific monetary policy.

Tax for UK investors in Hong Kong stocks

Capital gains tax

Capital gains on HKEX shares held outside an ISA or SIPP are subject to UK capital gains tax above the £3,000 annual allowance in 2026/27. CGT rates on shares are 18% for basic-rate and 24% for higher and additional-rate taxpayers. There is no Hong Kong capital gains tax.

Dividend withholding tax

Hong Kong does not levy withholding tax on dividends paid to non-resident investors. This means UK investors receive the full dividend declared by HKEX-listed companies without a deduction at source. The dividend is then subject to UK income tax in the normal way above the £500 dividend allowance for 2026/27.

Hong Kong stamp duty

Both the buyer and seller of HKEX-listed shares pay Hong Kong stamp duty of 0.10% on each transaction, collected by the exchange. This is separate from any UK tax and is not offset against UK CGT or income tax.

Hong Kong stocks and new listings: what to watch

The strong IPO pipeline at HKEX going into 2026 means new listing opportunities continue to emerge for investors monitoring the Hong Kong market. The primary focus is on AI-related companies, mainland Chinese industrials and advanced manufacturing businesses seeking international capital through dual A+H listings.

For UK investors tracking upcoming IPO opportunities more broadly, whether in Hong Kong or closer to home, the pipeline of anticipated listings includes names such as Shawbrook Bank, Revolut and Verisure. The research process for any new listing, whether on HKEX or a UK or European exchange, involves reviewing the prospectus, sector comparables and valuation relative to peers.

Buying Hong Kong stocks: advantages and risks summed up

Advantages

1. Access to some of the world's most significant technology and consumer companies, including Tencent, Alibaba and Xiaomi
2. No Hong Kong withholding tax on dividends, meaning UK investors receive the full declared dividend
3. No UK stamp duty reserve tax on HKEX purchases
4. Strong IPO pipeline, with HKEX ranked the world's top IPO market in 2025
5. Gateway to Chinese economic growth through a relatively well-regulated international financial centre
6. Hang Seng Index accessible via ETFs, CFDs and spread bets as well as direct share purchase

Disadvantages

1. Time zone makes active trading during HKEX hours impractical for most UK investors

4. Most HKEX-only stocks are not ISA-eligible for UK investors
5. Hong Kong stamp duty of 0.10% applies to both purchases and sales
6. China macro risk: HKEX is sensitive to mainland Chinese economic conditions, trade policy and regulatory changes

A word on the political and regulatory risk element

The relationship between Hong Kong and mainland China has had a direct impact on stock market performance in recent years. The introduction of the National Security Law in June 2020 triggered a sharp sell-off in Hong Kong-listed stocks, with the Hang Seng falling more than 20% over the subsequent months as investors reassessed the territory's political autonomy. 

More recently, regulatory crackdowns by Beijing on technology, private tutoring and property sectors in 2021 wiped hundreds of billions of dollars from the market capitalisations of companies including Tencent, Alibaba and Meituan in a matter of weeks. 

While the regulatory environment has stabilised since then and Beijing has actively sought to restore investor confidence, the episode demonstrated how quickly policy decisions in mainland China can translate into significant losses for holders of HKEX-listed stocks. This remains a risk that has no direct parallel in Western equity markets and should be factored into any position sizing decision.
