The dollar eased against a basket of currencies on Wednesday, but remained near the 2-decade high hit on Monday, as traders braced for more interest rate hikes from the U.S. Federal Reserve.
The dollar index, which measures the greenback against a basket of six currencies, was last down 0.1% at 108.66, after earlier coming within a whisker of Monday's two-decade peak of 109.48.

A steady line of Fed officials have reiterated support for further rate hikes to quell decades-high inflation, the latest being Cleveland Fed President Loretta Mester, who said on Wednesday that rates will have to rise to "somewhat above 4%" by early next year and then be held there for some time.
The comments followed a hawkish speech from Fed Chair Jerome Powell at the Jackson Hole central banking symposium in Wyoming last week that slammed the door shut on the idea that the Fed might pivot and begin lowering rates by mid-2023.
"We're still trading on Jackson Hole," said Joseph Trevisani, senior analyst at FXStreet.com. "The idea that they're going to do a 180 and reverse again if we end up with negative growth in the third quarter just doesn't seem possible."
Traders are now pricing in about a 68.5% chance of a 75 basis point Fed rate hike next month, according to data from Refinitiv.

The euro was last up 0.31% at $1.0047.
Inflation in the euro zone rose to another record in August, beating expectations and solidifying the case for further big European Central Bank (ECB) rate hikes.
A growing number of ECB officials have been calling for oversized rate hikes to combat surging inflation, which could exceed 10% in the coming months.
