European derivatives traders have gained access to Eurex US, after the fledgling Chicago-based all-electronic exchange secured the necessary regulatory approval. Eurex US can now be accessed from Belgium, Finland, Germany, Gibraltar, Ireland, Sweden, Switzerland and the UK.

The move to allow European customers on to the exchange is a key step in Eurex's ambitions to wrest away volumes in US treasury futures from its main US rival, the Chicago Board of Trade (CBOT).
