The Financial Conduct Authority (FCA) has levied a substantial fine of £61.6 million against Citigroup for a significant trading controls failure that resulted in the mistaken sale of $1.4 billion (£1.1 billion) worth of equities. This incident, which occurred in May 2022, sheds light on the critical importance of robust trading controls and real-time monitoring systems in financial institutions to prevent such costly errors.
At the heart of the issue was a “fat-finger trade,” a term used to describe situations where human error leads to the input of incorrect information. In this case, a trader at Citigroup’s London office intended to sell a basket of shares valued at $58 million (£45.5 million). However, due to an inadvertent error, the trader created a basket valued at a staggering $444 billion (£349 billion).
Despite a pop-up alert on the trader’s screen, indicating a potential error, the trader manually overrode the alert without thoroughly reviewing the warnings contained within it. This oversight allowed the erroneous trade to proceed, resulting in the sale of $1.4 billion (£1.1 billion) in shares across several European exchanges.
While the mistake was swiftly rectified within minutes, its impact was exacerbated by coinciding with a sharp decline in the value of some Nordic stocks. Citigroup’s internal controls successfully prevented $255 billion (£200 billion) of the erroneous trade from being executed. However, $189 billion (£149 billion) in shares were sent to a trading algorithm designed to execute the sales, compounding the situation.
Efforts to cancel the erroneous order were futile, as a significant portion of the shares had already been sold. The consequences of the error extended beyond financial losses, potentially impacting market stability and investor confidence.
In response to the incident, the FCA conducted an investigation and found significant deficiencies in Citigroup’s trading control framework. Specifically, the FCA highlighted the absence of a hard block mechanism that could have rejected the erroneous basket of equities entirely, preventing any of it from reaching the market. Furthermore, Citigroup’s real-time monitoring systems were deemed ineffective, resulting in delays in escalating internal alerts about the erroneous trades.
As a result of its findings, the FCA imposed a fine of £27.8 million on Citigroup, while the Prudential Regulation Authority (PRA) imposed an additional fine of £33.9 million. Citigroup has since agreed to settle with the regulators, acknowledging the shortcomings identified and committing to address them.
Steve Smart, joint executive director of enforcement and market oversight at the FCA, emphasized the importance of effective systems and controls in preventing such errors and maintaining market integrity. He underscored the need for financial institutions to continuously evaluate and enhance their systems to adapt to the speed and complexity of financial markets.
Citigroup’s response to the incident underscores its commitment to regulatory compliance and remedial action. A spokesperson for Citigroup expressed satisfaction with resolving the matter and highlighted immediate steps taken to strengthen systems and controls to prevent similar incidents in the future.
Overall, the Citigroup trading controls failure serves as a stark reminder of the critical importance of robust risk management practices in the financial industry. It underscores the need for continuous vigilance and investment in technology and processes to mitigate the risk of costly errors and maintain market confidence.
