London’s financial resurgence accelerates with regulatory reforms and global partnerships

Britain’s financial markets have registered a marked upswing this year, a recovery the Financial Conduct Authority’s chief executive, Nikhil Rathi, set out at Goldman Sachs’ trading conference on 26 February. According to his presentation, London has climbed the Global Financial Centres Index to sit only one place behind New York, a turnaround from weaker positions in recent years that Rathi credited to a mixture of regulatory reform, market infrastructure upgrades and talent development. “We gained ground last year,” he told delegates, and he described the city’s resurgence as a “quantitative trading renaissance.”

Industry figures cited by Rathi point to tangible gains across multiple asset classes. Foreign exchange volumes remain a core strength for London, while the London Metal Exchange reported a 15% rise in trading turnover year‑on‑year, underlining a renewed international appetite for the city’s commodity platforms. Crypto activity has also accelerated: the lead reporting notes a 40% jump in volumes on UK‑regulated exchanges in January 2026 and places last year’s crypto‑related investment into Britain at about $2.8 billion, trends the FCA says reflect growing confidence following its digital assets framework and tighter AML registration.

Regulatory change lies at the centre of the FCA’s pitch. Rathi highlighted a package of measures introduced since 2024 designed to simplify listing rules and make London more attractive to issuers. According to reporting, the FCA’s earlier reforms replaced the previous premium and standard listing tiers with a single equity category and set a longer‑term effort to streamline eligibility and governance requirements to draw a broader set of companies to the market. The regulator has also signalled further modernisation: a July 2025 initiative to review client categorisation rules aims to clarify protections and unlock capital by granting greater flexibility to wholesale investors.

Separate, more technical reforms are intended to improve market functioning. The FCA is backing a move to a T+1 settlement cycle that, according to FCA speeches in 2025, is planned for implementation on 11 October 2027 to reduce counterparty risk and bring the UK into closer operational alignment with other major markets. The authority has also announced new transparency guidelines and a timetable of around 50 reform initiatives that began rolling out in 2025, which it says are intended to cut costs for firms, support innovation and bolster investor confidence.

The regulator has pursued a mix of domestic and international partnerships to reinforce these aims. On 15 February the FCA announced a collaborative project with the Bank of England to develop a real‑time settlement system intended to speed transaction finality across UK markets. The FCA also finalised an agreement with the European Securities and Markets Authority on 30 January designed, the regulator says, to smooth cross‑border trading with EU counterparties. Rathi additionally reported high‑level engagement with US counterparts, noting a meeting with Securities and Exchange Commission officials as part of a wider push to align frameworks where possible.

Policy work on emerging areas is progressing alongside traditional market reforms. The FCA published a report in February on decentralised finance that set out regulatory challenges and options, and has opened consultations on capital requirement adjustments aimed at strengthening firms’ resilience to volatility, with final decisions expected later in 2026. A consultation paper launched on 10 February on proposed green bond standards signals an intention to anchor sustainable finance activity in London, while a task force formed on 18 February will monitor compliance in high‑frequency trading to guard against conduct risks associated with faster, algorithmic strategies.

The FCA’s broader crypto agenda has been bolstered by continuity in leadership: Nikhil Rathi was reappointed to lead the regulator for another five years in April 2025. Under his tenure the FCA has registered dozens of crypto firms under anti‑money‑laundering rules and is developing a dedicated authorisation regime intended to sit alongside traditional financial oversight by 2026, measures the authority argues will combine market development with consumer protection.

Not every competitor is standing still. Regulators and financial centres around the world are sharpening their offers: Singapore has signalled further tax incentives for financial services, continental exchanges are courting derivatives business, and other hubs are accelerating licensing and sandbox initiatives for AI and wealth management. Eurex has reported rising interest in rate futures trading, and regulators in Hong Kong and Dubai have introduced accelerated pathways for certain financial firms. Those moves, industry analysts say, increase pressure on London to keep innovating if it is to hold the recent gains.

Market participants and government departments are also playing a role. The FCA said it has been working with schools and universities since late 2025 to expand the talent pipeline, and the Department for Business and Trade is engaged in framing the green finance standards under consultation. Insurers have been active too: Lloyd’s syndicate formations focused on climate and cyber risks were reported as up in early 2026, reflecting shifting demand for specialised coverage.

Rathi urged continued industry engagement with the FCA’s consultative processes, arguing stakeholder input will shape the next phase of policy. The regulator paints the recent momentum as the product of deliberate reform rather than chance; critics and rival jurisdictions will be watching whether the package of listing changes, infrastructure projects, cross‑border accords and emerging‑asset frameworks together deliver sustained competitive advantage for London over the coming years.
