LONDON—The dollar was headed for its third weekly gain in a row and was near two-decade highs against other major currencies, as investors focused on U.S. jobs data due later on Friday that could bolster the case for aggressive interest rate hikes.
The U.S. currency has been riding high since Federal Reserve Chair Jerome Powell said at the Jackson Hole symposium in Wyoming last Friday that rates would need to be high “for some time” to combat inflation.
