Securities finance sits at the centre of global capital markets. Banks, brokers and investors use total return swaps and securities lending to finance positions, manage collateral and put inventory to work. Screens reached parts of this market long ago, but its most complex trades, and much of what happens after execution, are still handled over phone calls, chat messages and spreadsheets. A single total return swap can reference a basket of hundreds of securities, each needing substitutions, resets, and corporate action handling across the life of the trade. This is manual work that consumes trading capacity and carries real operational risk.
