London, May 12, 2026, 17:14 BST
- NatWest shares in London slipped roughly 4% to 561.6p, moving lower alongside other UK banks in a broader sector slide, not on any company-specific jolt.
- Higher gilt yields piled on, with sterling sliding and worries about Middle East-fueled inflation adding to the strain. Uncertainty over Labour’s leadership—and the risk of bigger bank taxes—also weighed.
- Bulls point to robust Q1 income, resilient capital generation, and the expectation that rates will stay elevated. Bears, though, see trouble: those higher rates are now paired with softer growth, rising political risk, and costlier credit.
NatWest Group shares slid hard on Tuesday—down 4.11% at 561.6p—but this wasn’t just about its earnings. The move spoke more to a broader UK risk-off mood. Reuters flagged declines across London banks: Barclays, Standard Chartered, NatWest and Lloyds all dropped between 2.2% and 4.2%, with financials dragging the wider European market lower.
NatWest stands out now as the closest thing to a straightforward, large-cap proxy for the UK economy. Bank shares tend to move quickly—almost a real-time gauge—when gilts drop, sterling slides, and traders lean toward pricing in looser government spending. On Tuesday, 30-year gilt yields climbed to 5.81%, that’s a level not seen since 1998; 10-year yields also jumped, hitting 5.13%. According to Reuters, shares in Barclays, NatWest, and Lloyds each lost more than 3%.
Politics delivered a jolt. Keir Starmer, battered by Labour’s disappointing local election showing, saw the pressure mount: four ministers had resigned by late afternoon, adding their names to a list of more than 80 MPs demanding he step down. But in the markets, it’s not just about who sits in No. 10. Traders are weighing whether the next leader might push policy further left—bigger spending, tougher taxes on banks.
The sector took the hit from that tax point. According to Reuters, JPMorgan analysts are now penciling in a jump in Britain’s banking surcharge—from 3% to 5%—if there’s a shift in the policy mix. That’s not great news for NatWest: higher state take means high returns and all that extra capital don’t look quite as compelling in the equity case.
Rates complicate things. Sure, higher interest rates typically boost banks by widening net interest margins—the gap between loan income and deposit costs. But that simple margin story doesn’t quite hold anymore. On Polymarket, odds of no move from the Bank of England in June stood at 82%. Another market gave a 65% probability for at least one BoE rate hike sometime in 2026. So, investors aren’t betting on a smooth rate-cutting cycle; they’re still wary of sticky inflation.
Prediction markets picked up on the political uncertainty, too. Polymarket traders, as reported by Reuters, put the odds of Starmer stepping down by the end of June at about 50-50. By year-end, they saw an 80% chance he’d be gone. Kalshi-connected probabilities, per OddsChecker on Monday, gave him a 36% chance of leaving before July 1, and 59% before September. Not numbers tied to any specific bank, but they end up shaping how investors value UK banks.
NatWest turned in a first-quarter operating profit before tax of £2.0 billion, edging past analyst estimates and up from £1.8 billion a year ago. The bank expects full-year income to land toward the upper end of its £17.2 billion to £17.6 billion guidance. CEO Paul Thwaite, however, flagged “market conditions are uncertain.” Reuters
The call kept a firm tone, with CFO Katie Murray noting a net interest margin of 247 basis points, a slight uptick of 2 basis points. The 2026 plan has shifted, now expecting Bank Rate to stay put at 3.75% instead of dropping to 3.25%. Management highlighted the structural hedge—a portfolio designed to lock in returns on a chunk of the balance sheet—as a buffer for income looking ahead.
The bullish argument stands out: NatWest posted £7.3 billion in loan growth and £3.1 billion in new deposits for the quarter, with return on tangible equity hitting 18.2%. CET1 capital ratio came in at 14.3%—an important gauge for the bank’s resilience. Should interest rates remain elevated and credit quality hold up, those numbers set the stage for ongoing income, steady dividends, and buybacks.
The bearish read is straightforward enough. NatWest logged a £283 million impairment charge—cash earmarked for potential loan losses. Out of that, £140 million reflects updated economic assumptions, factoring in fallout from the Middle East conflict. The bank now expects UK GDP to grow just 0.4% this year, down from its previous 1.0% call, and it’s pared back its house-price growth projection to 0.7% from 3.4%. That’s what the chart’s picking up on right now.
Peer action showed this wasn’t just a NatWest story. Lloyds faces heavier exposure to UK consumers, while Barclays leans on its investment bank but still deals with UK-specific political and tax clouds. Standard Chartered slipped along with the rest of the London-listed banks. Across the continent, European financials dropped 2% and the STOXX 600 lost ground as oil prices climbed and prospects for a U.S.-Iran peace deal dimmed.
Sentiment leans cautious, not outright negative. Michael Brown at Pepperstone flagged that gilts and the pound “could get worse before it gets better.” XTB’s Kathleen Brooks pointed to bond traders reacting to both Starmer’s possible exit and the threat of a messy leadership contest. For NatWest, it’s less about balance sheets right now—stability in Westminster and the gilt market is what matters most. Reuters
