The restrictions will also prohibit affected employees from purchasing individual stocks, holding investments in individual bonds, holding investments in agency securities (directly or indirectly), or entering into derivatives, the Fed said in a press release.
"These tough new rules raise the bar high in order to assure the public we serve that all of our senior officials maintain a single-minded focus on the public mission of the Federal Reserve," Federal Reserve Board Chair Jerome Powell stated.
The rules require 45 days' advance notice and prior approval for purchases and sales of securities, that investments be held at least a year. In addition, no purchases or sales will be allowed during periods of heightened financial market stress, the release added.
As a result of the new policies, senior Federal Reserve officials will be limited to purchasing diversified investment vehicles, such as mutual funds, according to the release.
The rules are intended to help guard against even the appearance of any conflict of interest in the timing of investment decisions, the release said.
