What a Stock Exchange Actually Does

What an exchange actually does

A stock exchange is not a building where money is made. It is a set of rules that makes a promise enforceable.

Say you want to buy a share from someone you have never met, who lives in another city, and hand over money before you receive anything. Almost nobody would do that alone. An exchange exists so that you do not have to.

It does four jobs.

It matches orders. Buyers and sellers submit prices, and a computer pairs them by a published rule, best price first, then by time.

It guarantees the trade. On the Tashkent exchange the venue itself can act as central counterparty, which means it stands between every buyer and every seller. If your counterparty disappears, that is the exchange's problem, not yours.

It produces a price. The last traded price is public information, the same number for a pension fund and for a student with one share.

It sets the terms of entry. A company that wants to list has to disclose its financials, and it has to keep disclosing them.

How it works in Tashkent

The Republican Stock Exchange Toshkent was created in April 1994, and for its first two decades it mostly processed privatisation transfers rather than open trading. The first real IPO came in April 2018, when the glass producer Kvarts sold shares to the public.

To buy anything on it you need three things: a licensed broker, an investment account with that broker, and a code from the Central Securities Depository, which keeps the record of who owns what. The depository is the part most people never think about, and it is the part that makes a share yours rather than your broker's.

The numbers are small and moving. As of January 2026 the exchange listed 85 ordinary and 38 preferred share issues worth about $9.7 billion, with roughly 862 securities admitted to trading in total once the over-the-counter segment is counted. Daily trades went from about 300 five years ago to some 5,000 now. Weekly turnover during July 20 to 24 was 308.7 billion soums, about $26 million, and shares were 99% of it.

Ownership is worth knowing. The state holds the majority of the exchange, and Korea Exchange has held a minority stake since 2016, which is where the current trading platform came from. The regulator is NAPP.

For comparison: Hong Kong

Hong Kong Exchanges and Clearing does the same four jobs, at a different order of magnitude.

At the end of June 2026 it had 2,748 listed companies with a combined market capitalisation of about HK$43.3 trillion, roughly $5.5 trillion. Average daily turnover in the first half of 2026 was HK$283 billion, around $36 billion a day.

Put those two numbers next to each other. Hong Kong trades Tashkent's entire weekly volume in about a minute.

The gap in listings is smaller than the gap in money: 2,748 companies against 123 share issues is a factor of 22, while the difference in daily turnover is a factor of several thousand. Uzbekistan does not lack companies. It lacks the people trading them.

Hong Kong also shows what an exchange becomes when it works. It raised HK$210.2 billion, about $26.8 billion, in IPO proceeds in the first half of 2026 alone, from 87 new listings, and it was the world's leading venue for IPO money in 2025. The exchange operator is itself a listed company: you can buy shares in the exchange, on the exchange.

Why any of this matters here

An exchange is infrastructure, like a payment system or a court. It is boring when it works and expensive when it does not, and its value shows up as a lower cost of capital for every company in the country rather than as anything visible to an individual.

On our reading, this is the part of the story that gets skipped. The debate in Uzbekistan is usually about whether the stock market is a good place for a person to put money. The prior question is whether the country has working market infrastructure at all, because everything else depends on the answer.

Hong Kong entered 2026 with more than 300 companies in its listing pipeline. Tashkent's pipeline is five state banks.
