The Commodities and Futures Trading Commission (CFTC), the regulatory body for US futures exchanges, has extended the comment period for Eurex's proposed US derivatives market by another two weeks, potentially delaying the exchange's launch in February next year.

The surprise move comes just as the original two-week period has elapsed, and despite the fact that no official comments or complaints have so far been submitted to the regulator. A notice from the regulator said that interested parties had subsequently requested that the comment period be extended, but offered no explanation as to why these had not been posted through the official channel made available.
