Commercial banks in New York City foundet the first major clearing house, the New York Clearing House, in 1853 to streamline the clearing and settlement of checks. Before the New York clearing house was founded, employees of 60 banks worked on the clearing and settlement process, rushing through the city to present checks to each other. A time-consuming process that led to disputes and inevitable errors. The establishment of the clearing house improved the situation almost immediately. There were significant savings in time, effort and financial costs, so by the end of the 19th century, many check clearing houses were already in existence throughout the United States. In Europe, as late as 1899, the London Stock Exchange was the only exchange with a clearing house.
