HKEX Is Trying to Own the Definition of "China"

Hong Kong's exchange operator makes its money on tolls: a small fee every time somebody trades a stock, a future, an option, or clears a transaction. The odd part of the current story is that Hong Kong Exchanges and Clearing (HKEX) has spent the last two years getting into the index business — the business of deciding which stocks count as "China."

In November 2024, HKEX and Hang Seng Indexes, the region's biggest index compiler, jointly launched the Hang Seng HKEX Stock Connect China Enterprises Index, ticker SCCEA, the first co-branded index between the two. The timing was the tenth anniversary of Stock Connect, the tunnel that lets foreign investors buy mainland-listed stocks and mainland investors buy Hong Kong stocks.

The interesting thing about the SCCEA is what it decides "China enterprise" means. The old benchmark with almost the same name — the Hang Seng China Enterprises Index, HSCEI, the template for the new one — started life as a measure of H-shares: companies incorporated in mainland China that float shares in Hong Kong. That legal test had a hole in it. The Chinese companies the world actually cares about, Tencent and Alibaba, are incorporated in the Cayman Islands. So for most of its history the flagship "China enterprise" index left out the most famous Chinese companies — a gap Hang Seng Indexes only patched in 2018 by adding red chips and private companies. The SCCEA just skips the legal test. Its membership is defined by plumbing: take the 80 largest Chinese companies whose shares are tradeable through Stock Connect, whether they list in Hong Kong, Shanghai, or Shenzhen. Tencent ends up sitting next to Kweichow Moutai and CATL in one book, computed in yuan, any single stock capped at 8 percent, rebalanced quarterly.

Why would an exchange want to do an index company's job? Because benchmarks are a business. An index firm collects licensing royalties on every product that tracks its benchmark and sells the data; and a benchmark with real liquidity attracts ETFs, futures, and options, which bring the trading and clearing fees an exchange actually lives on. HKEX's chief executive, Bonnie Chan, describes the logic as a "liquidity flywheel": indices attract index-linked products, products attract turnover, turnover attracts listings, listings attract more indices. The co-branding with Hang Seng Indexes is the clever bit — HKEX borrows decades of methodology credibility from the incumbent compiler while keeping the products inside its own house: any ETF would list on HKEX's exchange, any futures contract would trade and clear through its own infrastructure. In effect, the exchange is collecting index-company rent on top of its venue fees.

And it has been busy. In December 2025 it launched the HKEX Tech 100, its first proprietary Hong Kong equity index, and licensed it to mainland manager E Fund, whose ETF tracking it now trades in Hong Kong — the first ETF on an HKEX-branded index. In April 2026 it added a semiconductor index co-branded with Korea Exchange and a combined Hong Kong–US tech index, signing licensing deals with five issuers for ETFs. The SCCEA was the first move in the same campaign. And it is the one where the follow-through is missing.

Here is the state of play, almost two years on. The SCCEA is a working index, around 3,900 in late August. But no ETF tracking it is listed in Hong Kong, and no SCCEA futures or options appear on HKEX's derivatives roster. The launch announcement promised "new product innovations" based on the index; so far that is a statement of intent. It is a benchmark in search of a tracker.

That gap matters because the shelf is crowded. The old HSCEI already has deep futures and options markets, traded since December 2003, on the very stocks the SCCEA mostly overlaps with. MSCI's China A50 Connect futures, HKEX's own A-share hedging product, have been live since October 2021. US investors already own China through broad ETFs. The SCCEA's one clean advantage is completeness — one book spanning Hong Kong and mainland listings — and completeness only becomes valuable when somebody packages it into a product. There is also a real tension inside the plan: a new, broader contract on roughly the same stocks as the HSCEI could split liquidity rather than add it. Cannibalizing your own contracts is not crazy — the fees land in the same pocket either way, through HKEX's own clearing house — but it only pays off if the "one book" China index becomes the China index, not another China index on a crowded shelf.

For a US retail investor, the reason this matters is mostly what it would create. There is currently nothing to buy that tracks the SCCEA: no ETF, no futures, no options. If a fund manager licenses the index the way E Fund licensed the Tech 100, the result would be a single wrapper holding China's largest Hong Kong- and mainland-listed companies — including A-shares you otherwise reach only through specialist China ETFs. That would be a genuinely different way to own the whole China economy in one product, and a new hedging tool for people who already hold Chinese stocks.

As a stock, HKEX is priced for the flywheel to keep spinning. First-half 2026 revenue and other income hit HK$16.7 billion, up 19 percent, with profit up 24 percent to HK$10.6 billion, powered by record trading volumes, a busy IPO pipeline, and Stock Connect revenue up 57 percent to a record HK$2.85 billion. The shares trade near HK$418, around 28 times normalized earnings, with a dividend yield around 3 percent. The index business is a small slice of that today; it matters as a funnel feeding the derivatives and ETF volumes that produce HKEX's biggest fees.

So when you see headlines that HKEX "plans to launch" a Stock Connect China enterprise index — the index is already launched, live, and quoting near 3,900. What has not happened is the product. That is the whole case in one line: HKEX has decided what "China" means, and the bet is that the toll booth gets paid again every time somebody trades its definition. Watch the launch notices.
