At the New York Stock Exchange, the neo-classical bastion of American capitalism, blue-smocked traders gathered around TVs to watch Fed Chair Janet Yellen explain the move.

A trader turned up the sound.

“Turn it down!” someone yelled.

Laughter.

“Maybe Janet Yellen is in the bathroom,” a trader quipped.

The hike was “almost anticlimactic,” said Peter Costa of Empire Executions and a NYSE governor.

Costa wasn’t even at his booth, where he executes trades. He was letting the market settle down before getting back in, he said.

Peter Tuchman of Quattro Securities, a fixture on the exchange floor for 30 years, agreed.

“It’s crazy,” he said. “There’s nine years of anticipation.”

Stephen Guilfoyle of Deep Value Execution Services savored the Fed’s grand moment.
