The UK financial services sector has faced significant upheaval following the Competition and Markets Authority’s (CMA) investigation into anti-competitive practices involving UK government bonds, also known as gilts.
Concluded on 21 February 2025, this landmark case reportedly exposed unlawful conduct by some of the world’s largest banks, revealing how their actions potentially undermined fair competition in a critical financial market.
At The Competition Lawyers, we are dedicated to empowering businesses, investors, and consumers to understand the implications of these findings and pursue justice for any financial harm suffered. This article delves into the details of the CMA’s investigation and its broader impact on the financial sector.
The CMA launched its investigation in November 2018, targeting suspected anti-competitive arrangements in the trading of UK government bonds, a vital component of the UK’s financial ecosystem. These bonds, issued by the government to finance public spending, can be heavily traded in global markets, making their integrity essential for economic stability. The CMA’s probe focused on whether major financial institutions had engaged in practices that distorted competition, ultimately harming investors and the broader economy.
On 21 February 2025, the CMA reportedly issued five separate infringement decisions, confirming that five pairs of banks – Citigroup, Deutsche Bank, HSBC, Morgan Stanley, and Royal Bank of Canada – had reportedly violated competition law. The violations reportedly stemmed from unlawful exchanges of competitively sensitive information in one-to-one Bloomberg chatroom conversations between individual traders from 2009 to 2013. These discussions are said to have involved sharing details about pricing, trading strategies, and market positions, all of which potentially gave the banks an unfair advantage and disrupted the competitive process. The CMA imposed fines exceeding £100 million, underscoring the gravity of the misconduct.
This case highlights the critical need for transparency and fairness in the market for UK government bonds, where even minor distortions can have significant ripple effects.
Anti-competitive practices uncovered by the CMA have profound implications for the financial sector and its stakeholders. By colluding to share sensitive information, the banks could distort the pricing and availability of UK government bonds, potentially inflating costs for investors, pension funds, and other market participants. Such actions can not only erode trust in financial institutions but also increase transaction costs, which can ultimately be passed on to consumers. For example, higher costs for gilts could affect pension funds’ returns, impacting retirees, or increase borrowing costs for the government, placing a burden on taxpayers.
The CMA’s findings, supported by the Financial Conduct Authority (FCA), send a powerful message that anti-competitive behaviour will face severe consequences. Beyond the immediate fines, the case exposes systemic vulnerabilities in financial markets, prompting calls for stronger oversight and compliance measures. For businesses and consumers, this serves as a wake-up call to scrutinise the practices of financial institutions and seek redress for any losses incurred. The ripple effects of these violations extend far beyond the banks involved, affecting the integrity of the financial system as a whole.
The CMA’s findings provide a robust foundation for potential action against the banks involved in this case, as their actions likely caused financial losses for investors, businesses, and other market participants. By holding these banks accountable, the aim is to restore fairness to the market and ensure that those responsible face the full consequences of their actions.
