The dollar index fell to a two-week low, down 0.68%, after a weaker-than-expected US June payroll report dampened speculation of imminent Federal Reserve tightening. US nonfarm payrolls rose by 57,000, well below the 113,000 forecast, while May's figure was revised down to 129,000 from 172,000. The unemployment rate unexpectedly dipped to a one-year low of 4.2%, and average hourly earnings matched expectations with a 0.3% monthly increase. The euro climbed to a one-and-a-half-week high, up 0.61%, supported by Italy's unemployment rate unexpectedly falling to a record low of 5.0%. The yen rallied sharply to a two-week high against the dollar, down 0.97%, amid a Reuters report that Japanese authorities may intervene abruptly to support the currency, with Finance Minister Satsuki Katayama noting alignment with the US on bold currency steps. Gold and silver prices surged to one-week highs, with August gold up 1.48% and September silver up 2.60%, as the weaker dollar and reduced rate-hike expectations boosted precious metals.
