The US dollar index is up by 0.8% at 103.01 as of 7:21 a.m. ET - an almost 14-year high.
On Wednesday, the Federal Reserve decided to raise its benchmark interest rate by 25 basis points to a range of 0.50% to 0.75%, as virtually all market watchers were expecting.
In its unanimous decision, the Federal Open Market Committee (FOMC) noted improvement in the jobs market and the drop in the unemployment rate to a pre-recession low.
Additionally, the committee raised its expectation for the number of hikes in 2017, up to three from the prior forecast of two.
The dollar first started strengthening against most major and emerging market currencies after Donald Trump's election in mid-November.
