NatWest faces £140m Iran-war hit as UK growth slows, inflation rises

NatWest said on May 1 that it booked a £283m net impairment in the first quarter, roughly £140m of which reflected an update to its macroeconomic scenarios to account for the economic fallout from the Iran war. The lender reported operating profit before tax of around £2.0bn for January–March, slightly above analyst consensus, and said total income rose year‑on‑year.

The bank’s disclosure indicates the additional charge stems from a multiple economic scenario (MES) update, which incorporated higher geopolitical risk and weaker equity markets. Management highlighted that while revenue and net interest income improved, the outlook for UK growth was downgraded and inflationary pressures had increased, prompting a prudent provisioning stance.

Market reaction was notable: NatWest shares fell after the report and UK equity benchmarks, including the FTSE 100, reflected sensitivity to the region’s geopolitical developments. Although the impairment reduced headline profit, NatWest emphasised ongoing cost savings and resilient lending income as offsets that support near‑term profitability. Investors are watching whether revenue momentum can absorb future provisioning needs.

The move echoes similar provisions taken by other European lenders this quarter as banks reassess downside scenarios amid the Middle East conflict. The additional provisions follow post‑2008 accounting frameworks designed to capture expected credit losses earlier, and signal a broader industry shift toward more conservative loss recognition in the face of heightened macro uncertainty. UK macro indicators—slower GDP projections and rising inflation—compound the sector’s risks.

Analysts say NatWest’s core franchise remains profitable, but warn that further deterioration in the UK economy or prolonged geopolitical instability could lead to higher impairment charges in coming quarters. Key items to monitor are the group’s income guidance for 2026, loan impairment rate trends and capital ratios; continued cost discipline may help preserve returns if top‑line growth moderates.
