** BofA Global Research says that refining margins have fallen from "supernormal peaks," cutting its 2026 forecast by 20% and prompting cuts to its earnings estimates on oil majors
** It notes that refining margins have plummeted by about 45% in the last month, alongside a 5% drop in most major oil company share prices
** It adds that Shell's SHEL.L weak Q4 trading update has kicked off earnings season, signalling potential further consensus downgrades
** BofA cuts Spanish oil and gas company Repsol REP.MC to "underperform" from "neutral," citing rapidly deflating refining margins and expecting its cash return outlook to disappoint, too
** The broker also downgrades Finnish biofuel maker and oil refiner Neste NESTE.HE to "neutral" from "buy," as weaker margins remove upside to 2026 consensus
** It keeps France's TotalEnergies TTEF.PA as its top pick
