The UK's financial watchdog has scrapped a rule that forced banks to wait seven days before publishing their own research during a company's stock market launch. The change was published in policy statement PS26/16 on 5 August 2026 (FCA). The regulator announced the move the day before, saying it was designed to support UK listings (FCA).

Here is what was happening. When a company sells shares to the public for the first time, it is called an IPO. The banks running the sale produce their own research report about the company. Think of it like a restaurant review written by the restaurant's landlord — there is a built-in connection. That is why it is called "connected research." Independent analysts, who have no tie to the deal, write "unconnected" research. Under the old rules, the banks' research had to wait seven days after the independent research came out. The idea was to make sure all investors got information at roughly the same time.

The FCA's own consultation paper, CP26/14, admitted that the delay and the broader rules had "added unnecessary market risk and costs" (FCA). That consultation opened on 27 April 2026 (Reuters). PS26/16 finalises what CP26/14 proposed: getting rid of the 7-day delay and loosening the rules around how and when the banks' research reaches the market. The FCA confirmed it will go ahead with the changes, removing a step that companies and banks said created timing problems and extra cost without actually protecting investors more.

The broader context here is a longer campaign to make the UK a more attractive place for companies to list. In July 2024, the FCA pushed through its biggest overhaul of listing rules in decades (Reuters). In January 2026, the regulator made it easier for companies to raise money, requiring a detailed investor document (a prospectus) only when issuing shares equal to 75% of what the company already has (Reuters). By October 2025, the FCA was already looking at further changes to speed up IPOs, including scrapping a two-stage filing system (Reuters). Removing the 7-day research delay is the latest step in that direction.

But the FCA has flagged a catch. Changing the rules alone will not be enough to draw companies to London (Reuters). That matters for anyone wondering how much difference this will make. Whether a company lists in London depends on things like the share price it can get, how easy it is to find buyers, and overall market conditions — not just the rulebook. A faster research-release timeline helps the banks running the deal and may slightly shorten the marketing period, but it does not fix the core question of whether companies think London offers better pricing than rival cities like New York.

For the banks involved, the change is simple. Their research can now be published without the artificial delay that previously kept it behind independent coverage. This removes a scheduling headache that complicated the marketing tours where company executives pitch investors, and created gaps where the banks' own analysts were effectively sidelined. Deal teams will need to update their IPO procedures and the internal rules that prevent sensitive information from leaking between departments. Compliance teams should read PS26/16 carefully, as it replaces the original rules in the FCA Handbook.

In my view, the real question is whether changes like this one, stacked on top of the 2024 listing reforms and the January 2026 capital-raising changes, add up to a meaningfully better environment for IPOs — or whether they are small tweaks to a system whose appeal depends on things the FCA itself says it cannot control. Rule changes can cut red tape, but they cannot create the share prices, the buyer demand, or the market confidence that ultimately decide where a company chooses to list.
