BEL 20 Index: A History of Former Constituent Companies
The BEL 20 serves as the benchmark stock market index for Belgium, tracking the performance of the twenty largest and most liquid companies listed on the Euronext Brussels exchange. Because the index is designed to reflect the current state of the Belgian economy, its composition is not static. Companies enter and exit the index based on market capitalization, liquidity, and corporate restructuring.
Over the decades, numerous firms across diverse sectors—from pharmaceuticals and banking to industrial goods—have held a place in this prestigious list before being replaced. Tracking these former constituents provides valuable insight into the evolving industrial landscape of Belgium.

Analysis of Former BEL 20 Constituents
The history of the BEL 20 reveals a transition from traditional heavy industries to a more diversified modern economy. Early constituents often included steel, cement, and energy firms, while more recent entries have leaned toward healthcare and specialized technology.
Industrial and Energy Transitions
Heavy industry played a significant role in the early years of the index. Companies like Cockerill-Sambre (Steel) and CBR (Cement) were staples of the Belgian industrial era. Similarly, the energy sector saw major shifts, with Tractebel and Electrabel eventually giving way to Engie, which remained in the index until March 2019.
Financial and Banking Evolution
The banking sector has seen considerable volatility and consolidation. Former members such as Generale Bank, Almanij, and Dexia reflect the changing nature of Belgian finance. Even global giants like ING Group were part of the index for a specific period between 2016 and 2021.
Healthcare and Biotechnology
In more recent years, the index has integrated high-growth sectors. Ablynx and ThromboGenics represent the biopharmaceutical wave, while Galapagos held a position from 2016 until March 2025.
