(Reuters) - San Francisco Federal Reserve Bank President Mary Daly on Friday called out the elevated uncertainties around the economic outlook, and said the U.S. central bank should be careful and deliberate with monetary policy. 

"Economic research will tell you that uncertainty is a source of demand restraint," Daly said in a post on LinkedIn. "We are also getting some mixed signals from markets. From a monetary policy perspective, all of that is a reason to be careful and deliberate."

The Fed has short-term borrowing costs in a "good place," she said, "and there are plenty of signs that the economy is solid."
