Historical Context

The Wholesale Market Brokers’ Association (WMBA) serves as a pivotal trade association for brokers operating within the UK’s money markets. Founded to ensure a transparent and efficient intermediation in the markets for wholesale money, the WMBA has significantly influenced the establishment and maintenance of market standards.

Detailed Explanations

SONIA (Sterling Overnight Index Average)

SONIA reflects the average interest rate at which banks lend to one another on an overnight basis, in the sterling money market. It is calculated and published daily by the Bank of England.

EURONIA (Euro Overnight Index Average)

EURONIA operates similarly to SONIA, but focuses on overnight lending rates within the eurozone, providing a benchmark for overnight unsecured loans in euros.

Mathematical Formulas/Models

SONIA Calculation: SONIA is calculated as the weighted average interest rate of all eligible sterling overnight unsecured transactions reported to the Bank of England by contributing banks.

Formula:

$$ \text{SONIA} = \frac{\sum (\text{Transaction Value} \times \text{Rate})}{\sum \text{Transaction Value}} $$
