Eurex US, the newly launched North American arm of the Swiss-German derivatives exchange, faces its latest test as it rolls out new incentive programmes designed to attract trading interest in its US treasury futures.

The exchange's move comes on the back of recent growth in the exchange's open interest, a crucial indicator of a contract's attractiveness. At the end of last week open interest on Eurex US's contracts had risen to 24,094 from just 18,374 at the end of June.
