Inter-Dealer Brokers (Examples)
Inter-dealer brokers (IDBs) are specialized financial intermediaries that facilitate trading between dealers in wholesale financial markets. They play a crucial role in providing liquidity and price discovery, particularly in less liquid markets or for large block trades where anonymity is important.
Core functions of inter-dealer brokers
Inter-dealer brokers serve several essential functions in financial markets:
- Anonymity preservation - IDBs enable dealers to trade without revealing their identities, protecting their trading strategies and positions
- Liquidity aggregation - By connecting multiple dealers, IDBs create deeper liquidity pools
- Price discovery - Through their central position, IDBs help establish market prices for less liquid instruments
- Market intelligence - IDBs provide valuable market color and trading flow information to their clients
Market structure and operations
IDBs typically operate through two main models:
- Name give-up - Where counterparty identities are revealed post-trade
- Fully anonymous - Where the IDB acts as counterparty to both sides

Role in market stability
During periods of market stress, IDBs become particularly important for:
- Maintaining market liquidity

Evolution of the IDB model
The IDB business model continues to evolve with:
- Increased electronification of trading
- Integration of algorithmic trading capabilities
