The forex constitutes the largest financial market and is the main user of central bank money. However, the foreign exchange currently faces a list of issues that need to be addressed.
1. It endures a long time-lapse between trading and settlement.
2. Moreover, it lacks transparency.
3. It entails surmounting high risks.
The main risk in foreign exchange trading is the settlement risk. Therefore, Settlement risks eclipse the credit risk and liquidity risk.
Credit risk happens when counterparties fail to deliver the currency or default on a Vostro account claim when subject to an insolvency procedure.
Liquidity risk arises when the counterparties do not settle the full value in time. Therefore, disabling the payee’s capacity to meet their own requirements. Thus, demanding an alternative resource to mobilize funds for immediate commitment at short notice. Therefore, this also reduces the ability to reuse committed funds.
CBDC represents a format of central bank money that is fully fungible with other central bank monetary liabilities. Thereafter, the token format takes on properties aimed at facilitating versatile access methods to additional functionalities for central bank money.
Moreover, the tokens are programmable. Therefore, this allows them to root- in the much-needed prudential and other monetary policy and financial stability parameters to protect and discipline CBDC circulation. Moreover, CBDC is also viewed as a substrate for further financial innovation with extended support features for the token-based financial ecosystems. Therefore, this also encompasses settlement in the token-based financial market infrastructures. Furthermore, it propels greater diversification in payments.
The issuance and trading of CBDC are best attained using a permissioned distributed ledger technology (DLT)-enabled network to ensure optimum performance, security, transferability, and privacy in transactions. The issuance of CBDC would be solely under the guardianship of the central bank. However, the network is to be maintained by the central bank and a number of resident financial institutions serving as operators of network nodes that validate and record all transactions. The tokens are to be controlled by private keys stored in electronic wallets. The electronic wallets could be held outright or via a custodial relationship included by resident banks of the issuing currency country.
The adoption of tokens sanctions the simultaneous execution of trading and settlement in one transaction; enabling instant and atomic settlement through simple exchanges of tokens (atomic swaps). The programmability of tokens assure that transactions are instant and are committed only upon meeting certain conditions.
The atomic swaps would enforce the risk mitigation measures and preclude any deferment between trading and settlement. This ensures both currency legs are available at the same time and allow for real-time reuse. Liquidity management would be eased as trading positions would not impede liquidity against the immediate availability of funds.
