Definition ∞ Wholesale payment settlement refers to the process of finalizing large-value payments between financial institutions, typically central banks and commercial banks. These transactions involve significant sums and are crucial for the functioning of national and international financial markets. The settlement process ensures the transfer of funds is complete and irreversible, reducing systemic risk. It forms the backbone of the financial system.
Context ∞ The modernization of wholesale payment settlement systems is a key area of focus for central banks globally, with many exploring distributed ledger technology, or DLT, for greater efficiency and speed. Discussions often center on the potential for DLT to reduce settlement times and operational costs, while maintaining the stability and security required for critical financial infrastructure. Interoperability with existing systems remains a primary challenge.
