Shares plunged as much as 9.4% on October 30 after NatWest Group's third-quarter earnings revealed a paradox: the bank is firing on nearly every cylinder, yet the one metric investors care about most — the outlook for income earned on loans and deposits — landed flat. The result wiped roughly £5 billion off the lender's market value in a single session as traders recalibrated what one of Britain's largest retail banks can earn next year.
The Numbers Were Good — Until You Looked Ahead
NatWest delivered a 21.6% return on tangible equity and £4.6 billion in quarterly income, with earnings per share up 13.2% to 57.4p.
But the stock fell sharply, suggesting investors were more focused on the bank's outlook than on the small earnings beat.
Management guided for "broadly stable" net interest margin into 2027, disappointing analysts who had expected margin expansion from the bank's large hedging book.
Jefferies warned that pressure on margins from new lending and more expensive funding could constrain net interest income growth next year.
Impairments Nearly Doubled, Signaling the End of Easy Credit
Impairment losses — money set aside for loans that may not be repaid — almost doubled to £277 million from £140 million the prior quarter and rose 81% year-on-year.
NatWest attributed the jump to the non-recurrence of prior-quarter releases and higher Stage 3 charges. At 24 basis points, the charge skirts the bank's own sub-25bp ceiling, leaving almost no cushion if the UK economy softens.
Competition and a Tax Hike Squeeze the Runway
CFO Katie Murray acknowledged deposit-margin expansion was offset by mortgage repricing and lending-mix pressure , a direct consequence of fierce competition among UK lenders for mortgage and savings customers. RBC flagged NatWest as especially exposed because virtually all of its revenue is UK-generated, and the bank's decision to defer its next buyback to February removed a near-term capital-return catalyst.
The Bull Case Rests on Volume, Not Price
Management expects the structural hedge — long-dated rate bets that lock in income — to contribute more than £1 billion of additional income in 2027, lifting total hedge income above £7 billion.
Customer assets and liabilities grew 14.2%, and lending rose 7.7% for the eighth consecutive year of above-target balance growth. If volume can compensate for flat margins, NatWest may still deliver income growth — but investors are no longer giving it the benefit of the doubt.
