The US dollar climbed against most major currencies on Thursday as several Federal Reserve officials made hawkish remarks about interest-rate hikes.

Boston Fed President Eric Rosengren said on Thursday that recent economic data warrants continued gradual interest-rate increases.

"If the incoming economic data continue to be consistent with gradual improvement in labor markets and inflation getting closer to target, the Fed should be ready to gradually normalize interest rates," he said.

Rosengren's words were echoed by his Kansas City counterpart Esther George, who urged the U.S. central bank to increase interest rate to avoid possible asset-price bubbles.

"I view the current level as too low for today's economic conditions," George said in a speech on Thursday, adding that interest-sensitive sectors can take on too much debt in response to low rates and grow quickly, and "then unwind in ways that are disruptive."

The dollar index, which measures the greenback against six major peers, was up 0.33 percent at 94.135 in late trading.
