Dollar near one-week high as markets grapple with Gulf tensions

The U.S. dollar held near a one-week peak as Middle East conflicts created energy supply fears. Markets also watched inflation risks as oil prices swung sharply near six-week highs. U.S. Treasury yields edged higher, reflecting concerns about rising consumer prices. Meanwhile, the New Zealand dollar strengthened after robust inflation data supported rate hike expectations. The euro and British pound showed little change against the dollar on Tuesday.
