Analysts said the monetary policy divergence between the tightening Fed and stimulative European Central Bank and Bank of Japan was firmly in place and drawing demand for the greenback.
The Fed's tightening policy fuels demand for higher-yielding U.S. debt compared to bonds in Europe and Japan, driving investment flows into the United States and boosting the dollar.
The euro fell 1 percent against the dollar to $1.08020, its lowest in a week and a half and last held near that level at $1.08070
"The Fed is gradually moving higher whereas other central banks, including the European Central Bank and the Bank of Japan, are maintaining accommodative policy," said Eric Viloria, currency strategist at Wells Fargo Securities in New York. "This is supportive of the dollar over time," he said.
Although Fed Chair Janet Yellen said Wednesday that tightening would be gradual, Fed officials' median projected target rate for 2016 remained at 1.375 percent. This implies four quarter-point rate hikes next year.
Analysts said some traders' surprise that the Fed's rate forecasts were not reduced continued to support the dollar.
"The median projection stuck to a trajectory for fed funds which is more hawkish than the market has been and even continues to price in," said Thierry Albert Wizman, global interest rates and currencies strategist at Macquarie Limited in New York.
