Globally, the dollar held near a 19-month high on Friday after a strong week of gains on rising bets of a larger Federal Reserve rate hike, Reuters reported.
The dollar index, which measures the greenback against a basket of currencies, was last down 0.05% at 103.17, remaining at its highest since April 2025.
The euro dropped 0.1% to $1.1049, hovering near its lowest level against the dollar since April 2025. For the week, it was down 0.8%, on track for its largest weekly loss since late September.
The Japanese yen was largely unchanged at 159.875 per dollar, near its lowest level since early September, fueling intervention concerns.
“If we do see a further sharp selloff in equity markets, that could be a negative for the US dollar,” said Carol Kong, currency strategist at Commonwealth Bank of Australia.
But “if we see further support for a 50-basis-point hike, there’s further upside in the dollar too,” Kong added.
