Dollar at week-high after US resumes attacks on Iran

The dollar index climbed to 101.18, its highest since July 2, as safe-haven demand rose after the US launched fresh strikes on Iran and revoked a licence allowing Iranian oil sales following attacks on three tankers in the Strait of Hormuz. Brent crude surged 2.6 percent to 76.12 dollars a barrel, extending a two-day rally, while the euro and pound eased against the dollar. The developments are negative for India as a major oil importer, with rising crude and a stronger dollar likely to pressure the rupee and weigh on sentiment.
