Dual-Capacity System is a working-capital concept used to evaluate operating cash needs, short-term funding, and business efficiency.
The dual-capacity system is a framework for trading on a stock exchange in which the roles of stockbroker and stockjobber (market maker) are distinctly separated and performed by different firms. This separation contrasts with the single-capacity system, where firms, known as market makers, combine these two functions. This structure was a hallmark of the London Stock Exchange until the notable change marked by the Big Bang on October 27, 1986.
