Explain briefly the following: Straight through processing (STP).

Straight through processing (STP) Straight-through Processing ('STP') is a mechanism that automates the end-to-end processing of transactions of the financial instruments. It involves use of a single system to process or control all elements of the work-flow of a financial transaction, including what is commonly known as the Front, Middle, and Back office, and General Ledger. In other words, STP can be defined as electronically capturing and processing transactions in one pass, from the point of first 'deal' to final settlement.
