It's 55-year-old Kevin Warsh.

Wall Street isn't sure what to make of Warsh yet.

Many are optimistic that Warsh will preserve the Federal Reserve's independence, even as they're also concerned he might be far from the easy-money kind of Fed chair that President Trump wants.

The conflicting views were reflected today by falling stocks, a rallying dollar, and the worst day for gold and silver in more than four decades.

Gold fell 11 percent and silver dropped 31 percent.

Warsh still has to be confirmed by the Senate, and the government's criminal investigation into current Fed Chair Jerome Powell might complicate that.

Republican Senator Tom Tillis of North Carolina said today that, though he considers Warsh a qualified nominee, he would oppose Warsh's confirmation until the Powell probe is resolved.
