Central counterparties (CCPs) reduce counterparty and liquidity risk in financial markets. By analyzing transactions in the Colombian peso market, it was found that using a CCP for clearing and settlement leads to more connected networks among financial institutions, reducing liquidity risk. Additionally, after CCP interposition, exposure networks show lower connectivity and higher distances, indicating a decrease in counterparty risk. This shows that CCPs change how financial institutions behave, creating two distinct economic structures in the market to lower risks.
