June 24 (Reuters) - U.S. cash crude differentials were little changed on Tuesday, the second day of the roll trading period, dealers said, as traders assessed a ceasefire between Israel and Iran.
The ceasefire was initially on shaky ground with U.S. President Donald Trump accusing both Israel and Iran of violating it just hours after it was announced. Oil futures fell 6% on Tuesday. O/R
Meanwhile, the roll trading period continued on Tuesday, a typically volatile three-day trading period during which traders square their positions. The roll begins after the U.S. front-month futures contract expires.
