KUALA LUMPUR (Jan 29): The ringgit is expected to trade in a tight range with downside bias between 4.19 and 4.20 against the US dollar next week. “As such the ringgit is expected to move in a tight range next week. However the upside bias for ringgit could come from crude oil prices which strengthened further following geopolitical risks,” he continued. For the week just ended, the ringgit ended slightly lower against the US dollar at 4.1880/1915 compared with last Friday's 4.1840/1870. The ringgit gained versus the euro to 4.6621/6660 from 4.7434/7468 a week earlier and rose against the British pound to 5.6031/6078 from 5.6764/6805 previously.
