Globally, the US dollar headed for its third straight week of gains on Friday, perched at a 17-month high as a bond market rout pushed borrowing costs across the globe to multi-decade peaks in the face of inflationary fears over higher oil prices, Reuters reported.
The dollar index, which measures the US currency against six rivals, was at 102.08, set for a 1% gain this week, its third consecutive weekly gain, a run it last had in May 2025.
The euro was at $1.1237, hugging its lowest level since May 2025, dragged by worries around France’s fiscal health. The yen was steady at 158 per US dollar.
Sterling was at $1.3187 while the Australian dollar was 0.18% softer at $0.6918, both hovering around their three-month lows.
Much of the dollar’s recent strength has come at the expense of the euro as the rising political risk in Europe and the energy shock from the seven-month-long war in the Middle East dented sentiment on the single currency.
