On 7 Oct 2026, WTI fell to US$88.28 a barrel (down US$1.16) and Brent to US$100.20 (down US$0.38) after the IEA agreed to speed up stock releases, with diesel first. The IEA says the release could add about 100 million barrels to supply. Prices remain near record highs amid the Iran conflict, so no fuel relief is guaranteed. Keep diesel and fuel budgets under review for the quarter, and do not assume a sustained price drop from one day's move.
