The tripartite representative also does not provide a negotiating platform for the parties to negotiate and execute transactions. Once a transaction has been agreed, — through an independent automatic repo system or directly by telephone or electronic communications — both parties independently inform the tripartite agent corresponding to the instructions and, if successful, deducted from the transaction. The agent automatically selects sufficient guarantees from the seller`s title account that meet the credit and liquidity criteria, concentration limits and initial margins set by the buyer. Selected guarantees are delivered to the buyer`s account in exchange for simultaneous cash payment. Then, the tripartite representative manages the evolution of the transaction: regular revaluation of the security, margining, payments of income on the security and (in the case of most European tripartite agents), replacement of security that no longer meets the buyer`s quality criteria, replacement to avoid a payment of income that triggers a tax event, and replacement at the request of the seller. Central banks The main task of a central bank is to manage the cost and volume of loans in an economy in order to control economic growth and inflation. They control the supply of liquidity, i.e. bank deposits with the central bank, most often through open market operations. Most central banks intervene in money markets to influence very short-term interest rates. Due to the size of the pension market, its role in financing other financial markets and the fact that repot reduces credit risk and reduces credit risk with public funds, Repo has become the preferred global instrument for central bank intervention in open market operations. In a tripartite filing, both parties (buyers and sellers) relocate the management of the collateral business to a tripartite representative, usually a central international securities deposit company (ICSD such as Euroclear Bank or Clearstream Banking) or a deposit bank, on the basis of a pre-defined set of rules and criteria agreed by both parties, namely the asset eligibility commission (type of asset eligibility) , issuer, currency, credit rating, maturity, index, , the size of issues, average daily trading volume, etc.). The tripartite representative acts as an intermediary between the two parties to the “Repo” and is responsible for the management of the transaction, including collateral allocation, market marking and security replacement. This agreement can provide economies of scale for its users and allow the buyer and seller of a pension to avoid the administrative burden of bilateral deposits.
Figure 26 shows a typical tripartite repo arrangement. In tripartite boarding, fees are traditionally charged to the guarantee provider (Cash-Taker). Cash providers operate free of charge in the triparties market. Tripartite Retirement Market, 21 market players, from both sides of the market using the triparty collateral management services provided by Euroclear Bank, have agreed to join a new group of collateral users created by the Brussels-based ICSD.
