UK fines banks $132 million for bond collusion

The UK’s Competition and Markets Authority (CMA) has fined four global banks a total of £104.5 million ($132.4 million) for exchanging sensitive information about UK government bonds between 2009 and 2013.
The financial institutions—Citi, HSBC, Morgan Stanley, and Royal Bank of Canada—reached settlements with the regulator following a long-running investigation into anti-competitive practices in the bond market, reports Reuters.
The CMA found that traders at these banks engaged in improper discussions via Bloomberg chatrooms, where they shared confidential details about the pricing and trading strategies related to UK government bonds, known as gilts.
The misconduct took place during the years following the 2008 financial crisis, a period marked by high market volatility and large-scale government intervention in bond markets. The investigation revealed that traders from competing banks had unlawfully exchanged information about pricing strategies in one-to-one conversations.
These discussions may have given the banks involved an unfair advantage in the market by allowing them to anticipate competitors' moves and adjust their own trading strategies accordingly. Such behavior undermines fair competition and could have impacted the cost of government borrowing.
Deutsche Bank Granted Immunity
The CMA’s probe initially identified five banks in breach of competition laws. However, Deutsche Bank, which, along with Citi, admitted to engaging in anti-competitive practices, was granted immunity from financial penalties under the regulator’s leniency program. This program provides exemptions for firms that self-report and cooperate with investigations.
The CMA’s decision underscores the regulator’s continued efforts to enforce competition laws in the financial sector. The fines serve as a strong warning to financial institutions engaging in collusive behavior, particularly in markets as critical as government bonds. Authorities worldwide have been increasing scrutiny on trading practices to ensure transparency and prevent market manipulation.
As regulators tighten oversight, financial institutions may face stricter compliance requirements to prevent similar violations in the future.
