The Financial Conduct Authority (FCA) has officially dismantled key restrictions governing initial public offerings (IPOs), marking one of the most decisive regulatory shifts in UK capital markets in years. Companies will benefit from easier initial public offering (IPO) listings thanks to changes to the rules from the FCA. This will allow the UK listings market to compete more effectively with global markets.

The reforms will reduce execution risk for issuers, lower compliance costs and make it easier for companies to access public markets. As part of the changes, the FCA will remove the 7-day waiting period for connected research during an IPO and simplify information-sharing requirements for issuers and firms. These changes support the FCA’s aim of enabling growth, investment and innovation, while continuing to uphold high standards of market integrity and investor protection.

Jon Relleen, Director of Infrastructure and Exchanges at the FCA, noted:

“We want the UK market to be an attractive place for companies to raise capital and grow. By making the UK listing regime more efficient, we are supporting the growth and competitiveness of UK capital markets.”

How 2018 Rules Stifled London’s Listing Pipeline

To understand the weight of these changes, one must examine how previous regulations bottlenecked the UK equity ecosystem. In 2018, under Policy Statement PS17/23, the FCA introduced strict guidelines designed to encourage independent equity research. The rules mandated a mandatory seven-day waiting period between the publication of an approved prospectus or registration document and the release of connected research by syndicate banks. Furthermore, syndicate teams were required to share substantially the same operational and financial information with unconnected, independent analysts as they did with internal connected teams.

Instead of levelling the playing field, these mandates created severe friction points:

Extended Execution Risk: A seven-day freeze in the public domain exposed listing candidates to macro-volatility, interest rate fluctuations, and geopolitical shocks. In volatile market cycles, a week-long delay frequently forced issuers to re-price down or pulled deals altogether.
Disproportionate Compliance Burden: Managing information flows to third-party analysts increased legal oversight and administrative overhead for investment banks and issuing firms without generating meaningful independent coverage.

The Transatlantic Flight: Driven by rigid execution mechanics, higher free-float requirements (previously 25%), and restrictive dual-class share rules, high-growth UK tech icons looked across the Atlantic. Semiconductor giant Arm famously chose New York’s NASDAQ over London, citing deeper liquidity and greater structural flexibility. Similarly, Swedish buy-now-pay-later pioneer Klarna filed confidentially in the US, while UK fintech leaders like Wise opted for direct listings with custom voting rights to retain control.

PS17/23 vs. The Updated Framework

The FCA’s latest policy shift directly tackles the structural liabilities of the 2018 rules. The table below outlines how key listing requirements have transformed to support issuer efficiency.

Regulatory Domain
Pre-Reform Framework (2018–2025)
Updated FCA Framework
Impact on Market Execution

Connected Research Timing
Mandatory 7-day wait after prospectus/registration document
Immediate / Simultaneous release permitted alongside prospectus
Shaves 7 days off the public IPO timeline; minimises market risk exposure.

Unconnected Analyst Access
Syndicate banks forced to share identical data with independent analysts
Mandate removed; information sharing negotiated on a commercial basis
Lowers compliance overhead, limits information leaks, and cuts legal fees.

Public Free Float Threshold
Historical requirement of 25% minimum float
Reduced to 10% (aligned with recent FCA listing category overhauls)
Allows founders to raise capital while minimising early equity dilution.

Listing Category Structure
Split between Premium and Standard listing segments
Single Commercial Companies Category with streamlined voting rules
Eliminates rigid eligibility barriers for high-growth tech scale-ups.

H2 Outlook for UK Fintech and Crypto Enterprises

For late-stage fintechs, stablecoin issuers, and digital asset infrastructure firms, the removal of the seven-day embargo significantly changes the capital-raising calculus. Late-stage firms that previously found public market timelines daunting now face a streamlined route to market.

Compressed Time-to-Market: By allowing connected research to launch simultaneously with the prospectus, syndicate managers can build book-building momentum instantly. This compressed timeframe mitigates the pricing uncertainty that previously plagued mid-cap financial services IPOs, such as the initial public offerings of CAB Payments or Deliveroo.

Attracting Web3 & Digital Asset Scale-Ups: As the FCA finalises its broader regulatory framework for fiat-backed stablecoins and institutional crypto assets, clearing structural hurdles in the equity market creates a unified ecosystem. UK-based infrastructure platforms seeking hybrid funding—combining private token allocations with public equity listings—can now execute public offerings with standard US-style agility.

Restoring Regional Parity: While New York continues to command massive valuation multiples, removing regulatory frictions allows London to compete effectively on speed, efficiency, and legal certainty.

The FCA’s concession that previous research rules added costs and market risk without demonstrable benefits is a welcome reality check. By synchronizing research dissemination and stripping away legacy administrative drag, the regulator has given London a competitive fighting chance to capture the next wave of global fintech floats.
