overview

Stock Record

Any organization to be successful and efficient, It should be in control of its own goods and cash. Stock Record achieves that by maintaining current inventory or position of assets. For the brevity of the discussion, let’s take traded and settled position. traded position means what has been agreed to buy or sell with exchange by order execution, that helps to predict the future movement of asset. settled position reflects actual security position in CSD (Central Security Depository) and cash in clients accounts. settled position gives what bank actually hold in every moment.

Stock Record helps banks to lend money based on future position. For example, a hedge fund client executed an order to buy Singtel shares for 1 million. In Stock Record, it is receivable traded position, assuming that settlement happens in T + 3, bank can lend money based the predictive receipts of collateral. In this case, it is 1 million Singtel shares can be collateral.

Stock Records provides several key information like liquidity information wanted by the regulators, funding requirements for the cash accounts to avoid over due charges. It feeds banks general ledger for accounting

Clearing and Settlement

Clearing and settlement function moves the asset back and forth between investment bank and external parties like exchange or nostro agents(other bank). Once order to buy or sell a stock is executed in upstream(Front and Middle office), back office has responsibility to move ownership of asset. It has to pay money and receive the stocks or deliver the stocks and receive the money. Mostly, money and cash move in opposite direction.

It’s most of the instruction to exchanges and other banks pass thru swift network. Every instruction goes thru Anti-money laundering(AML), Office of Foreign Asset Control(OFAC) check as well as any checks stipulated local regulators. Clearing and settlement generally happens thru Central Counter Party Clearing House (CCP) to avoid the credit risk. Clearing means matching settlement instruction with CCP. Settlement means actual movement of ownership. Once settlement is done, It publishes information to Stock Record to rebalance its asset positions.

CCP interactions

Custody services

Custodial banks maintains client’s assets by getting fees. Issuer of the stocks pay dividends to the CSD which holds the asset, CSD in turn pay the asset to the Custodian banks, which in turn pays to the clients. Clients can give standing instruction to custodial bank for money it receive for dividend. like, credit to particular account, accumulate for particular tenure, invest in money market and etc.

Corporation will split the shares when the price reaches it’s high value, in order to be more attractive for small investor. In such situations, Custody services interacts with CSD to get their splits for their customers. Two corporation could merge or single corporation spin off a new corporation. all these actions possible change the quantity of stocks. Custody services ensures all the corporate actions are taken care for it’s clients.
