Citadel Securities UK Market-Making Profit Drops 38% as Parent Injects $100 Million

MixedMedium impact

Citadel Securities saw annual profit at its main UK market-making business decline by 38.3% to $29.2 million in 2025. Total income for the unit fell 18.7% to $252.5 million, hit by reduced trading activity across core markets and ongoing spending on expansion initiatives. To support rising working capital needs, the parent company contributed $100 million in fresh capital after skipping a dividend payment for the year.

The slowdown in market-making earnings comes despite strong overall performance for Citadel Securities globally and growth in its UK proprietary trading unit. A sister UK investment arm generated $1.01 billion in profit, lifting combined earnings for the firm's two main UK entities to $1.04 billion. Operating expenses for the market-making arm dropped 11.2% to $212.6 million, but lower trading revenues pushed return on equity down to 7.12% from 12.73% a year earlier.

Looking ahead, the market-making branch is seeking further growth through international and asset-class expansion. The business continues to expand its sterling-denominated bond trading platform and plans to set up a mainland subsidiary to execute trades in China. Investors and market participants will watch whether these investments reverse the multi-year decline in European market-making returns.
