Malaysia's ringgit opened at 4.0895/0960 per dollar on Friday morning, slightly weaker than Thursday's 4.0875/0920 close but firmer against most major currencies, before a sharply weaker-than-expected U.S. jobs report reversed the day's dollar narrative. The U.S. Dollar Index later fell 0.5% to 99.4 near a two-month low after nonfarm payrolls declined by 23,000 in July and the previous two months were revised down substantially; the unemployment rate edged down to 4.1% even as labor force participation weakened. Investors scaled back expectations for a September Federal Reserve rate hike, while uncertainty over the Iran conflict and the Strait of Hormuz persisted after President Donald Trump said Iran and Oman negotiations were moving along but no agreement had been finalized.
