New york: The US dollar is on track to post its second consecutive weekly loss on Friday, amid escalating global tensions over the possibility of a US military operation against Iran, as well as the imposition of new tariffs on countries supplying Cuba with oil. The dollar index, which measures the US currency's performance against a basket of major currencies, rose 0.2% to 96.35 points, trimming its weekly losses to around 1.1%.

According to Qatar News Agency, the euro slipped 0.2% to $1.1940, while the Japanese yen weakened 0.17% to 153.39 per dollar. Sterling also edged lower, falling 0.1% to $1.3791, while the Australian dollar declined 0.2% to $0.7033. The New Zealand dollar eased 0.2% to $0.6066.

The dollar ended last week with its steepest weekly decline since April last year, reflecting mounting geopolitical uncertainty and concerns over global trade tensions.
