The dollar rose to fresh 20-year highs on Wednesday and the euro tumbled to a new two-decade low as rising energy prices cast a long shadow over the euro zone's economy but bolstered the U.S. currency's safe-haven appeal.
The dollar and euro were little changed after the release of minutes from the Federal Reserve's meeting in June, when the U.S. central bank hiked interest rates by an outsized 75 basis points in an effort to corral inflation.
Earlier, the dollar index , which tracks the greenback against six currencies, shot above 107 while the euro tumbled below $1.02, both levels last seen in December 2002. The index is up 12% year to date and is set for its best year since 2014.
The dollar has strengthened as energy prices are high and the Federal Reserve has been raising interest rates more quickly than most other central banks, said Shahab Jalinoos, global head of macro trading strategy at Credit Suisse.
"You have traditional macro factors that are driving dollar strength right now rather than a risk-adverse move," Jalinoos added.
The United States is a net energy exporter, while Germany is running a trade deficit for the first time since 1991, Jalinoos said.
"High interest rates in the U.S. and a trade shift which is beneficial to the U.S. adds to sustainability of the dollar's strength," Jalinoos added.
The dollar index rose 0.5% to 107.07, with the euro down 0.8% to $1.02. The index hit a high of 107.27 and the euro slipped 1% to a low of $1.063 earlier.
