Here part of the summary on the new rules provided by G. Gensler:

"The CFTC finalized a rule in October 2011 that addressed Congress’ direction to prevent any single trader from obtaining too large a share of the market to ensure that derivatives markets remain fair and competitive. Last fall, a federal court vacated the rule.

It is critically important, however, that these position limits be established as Congress required.

The agency has historically interpreted our obligations to promote market integrity to include ensuring that markets do not become too concentrated. When the CFTC set position limits in the past, it sought to ensure that the markets were made up of a broad group of participants with no one speculator having an outsized position. This promotes the integrity of the price discovery function in the market by limiting the size of any one speculator’s footprint in the market.

Position limits further protect the markets and clearinghouses, as such limits diminish the possible burdens when any individual participant may need to sell or liquidate a position in times of individual stress.

Thus, position limits help to protect the markets both in times of clear skies and when there is a storm on the horizon.

With a strong proposal ready for the Commission’s consideration today, we determined that the best path forward to expedite position limits implementation was to pursue the new rule and dismiss the appeal of the court’s ruling, subject to the Commission’s approval of this proposal.

Today’s proposed rule is consistent with congressional intent. The rule would establish position limits in 28 referenced commodities in agricultural, energy and metals markets as part of a phased approach.

It would establish one position limits regime for the spot month and another for single-month and all-months-combined limits.

Today’s proposed position limits rule builds on over four years of significant public input. In fact, this is the ninth public meeting during my tenure as Chairman to consider position limits.

We held three public meetings on this issue in the summer of 2009 and got a great deal of input from market participants and the broader public.

We also benefited from the more than 8,200 comments we received in response to the January 2010 proposed rulemaking to reestablish position limits in the energy markets.

We further benefited from input received from the public after a March 2010 meeting on the metals markets. In response to the January 2011 proposal, we received more than 15,100 comments."
