Paul Singer, the head of the $25 billion hedge fund Elliott Management, has never been shy about expressing his views.

And he stayed true to form at the DealBook conference on Thursday, blaming the Federal Reserve for widening the inequality gap in the United States.

“They are enablers, and I blame them for that,” Mr. Singer said.

In October, Janet Yellen, the chairwoman of the Fed, had sounded the alarm about rising economic inequality. That led some commentators to say that the Fed’s policy of quantitative easing had exacerbated the problem.

Mr. Singer has made no secret of his distaste for the Federal Reserve’s efforts to keep interest rates low as a way to stimulate the economy. That path, he argued on Thursday, has led to an artificial inflation of the prices of assets like stocks and bonds.

In “levitating” these assets, he continued, those who can invest — the already wealthy — have benefited, while those who cannot, including many in the middle class, are being left behind. Moreover, the Federal Reserve appears to be enjoying its role as, in Mr. Singer’s colorful description, as “the Atlas holding up the world.”

Over all, Mr. Singer appeared skeptical of those in power. Of Argentina, which his firm has fought to pay more on some of its government bonds, the hedge fund magnate argued that the country is trying to elevate a commercial dispute into “a dispute about national dignity.”

And of corporate boards, which Elliott takes on as an activist investor, Mr. Singer said that many boards haven’t fulfilled their role as overseers of management teams.
