Stock Market Today: FTSE 100 Futures Edge Up On OBR Debt Outlook

UK stocks are set for a marginally positive start on Friday, 30 Oct 2026, with FTSE 100 futures edging up as sentiment tracks the Office for Budget Responsibility’s latest debt and growth outlook. The OBR projects UK growth of 1.2% for 2026 and 1.0% for 2027, but also higher borrowing and an altered debt path, implying a looser fiscal stance and raising the key question of how gilt markets absorb extra supply. Higher borrowing can lift yields and feed into household and corporate borrowing costs, pressuring sectors with heavy refinancing needs. On company news, IMI expects a sixth consecutive year of mid-single-digit organic revenue growth, while Seplat Energy lifted production guidance to 145,000–155,000 boe/d and declared a 19.0p quarterly dividend.
