The Federal Reserve Board on Dec. 20 extended the comment period for a proposed rule on adopting additional limitations on physical commodity trading activities conducted by financial holding companies.

The proposed rule could lessen the risks physical commodity activities can have to financial holding companies.

The original comment period, which is set to close Dec. 22, has been extended until Feb. 20, 2017.

The Fed said the extension will give interested parties more time to examine the proposal and make comments.
