Lacker says bubble "possible" in long-term U.S. debt

Long-term U.S. debt markets could overshoot and create a bubble, although such a phenomenon would be hard to assess in real time, Richmond Fed President Jeffrey Lacker said on Friday.

"It's virtually impossible to say something is a bubble in real time. I do think markets at times overshoot, and that could be possible in the long-term debt market," he told reporters after a speech.
