A Clearing House is involved in aggregating transactions over a trading period and netting the positions to determine the liabilities of members. In financial markets, a clearing house acts as an intermediary between buyers and sellers to facilitate the smooth settlement of trades. It becomes the counterparty to both the buyer and the seller, guaranteeing the fulfillment of the trade. The clearing house aggregates transactions, calculates the net position for each member, and ensures the settlement of obligations. This process helps manage counterparty risk and ensures the integrity and efficiency of the financial markets.
