FTSE 100 Banks Face £2.6bn Bad-Loan Bill Amid Geopolitical Strain

What the Big Five are expected to report

Earnings season begins on 29 April when Barclays (LSE: BARC) publishes first-quarter results. Lloyds Banking Group (LSE: LLOY) follows on 30 April, Standard Chartered (LSE: STAN) on 1 May, and NatWest Group (LSE: NWG) on 2 May. HSBC (LSE: HSBA), Europe's largest lender, rounds off the cycle on 5 May.

The consensus pre-tax profit haul across the quintet sits just below £16bn, according to City AM's compilation of analyst estimates. That would edge past the £15.2bn secured in Q1 2025 but fall short of the near-£17bn recorded in Q1 2024 and the £18bn posted in Q1 2023, periods that benefited from a higher interest rate environment.

Net interest income is expected to hold firm. Russ Mould, investment director at AJ Bell, told City AM that the metric should be supported by "an almost total halt in interest rate cuts around the world." Stalled monetary easing, driven in part by inflationary pressures from the US, Israel and Iran conflict, has kept deposit margins wider than many forecasters anticipated at the start of the year.

Why loan-loss provisions matter more than profits

The headline profit figures will attract attention. The provisioning lines beneath them deserve closer reading.

Analysts are pencilling in aggregate impairment charges of £2.6bn across the five banks, as reported by City AM. That figure would represent the highest first-quarter charge since the onset of the Covid-19 pandemic in early 2020, when lenders rushed to build buffers against a sudden economic shutdown.

The comparison with the provisioning cycle that followed Russia's invasion of Ukraine in early 2022 is instructive. In Q1 2022, HSBC recorded an impairment charge of $642m (£476m), which dragged quarterly profit down 25 per cent to $3.4bn, according to the bank's filings. Lloyds set aside £117m in the same period, pulling profit to £1.6bn from £1.9bn the previous year.

Those charges, prompted by a seven per cent spike in inflation, proved partly conservative; some provisions were later released as the worst-case scenarios did not fully materialise. Yet the lag effect was real. Within two to three quarters of the 2022 provisioning increase, SME borrowers reported tighter credit terms and higher arrangement fees, according to Bank of England credit conditions surveys from that period.

"It would be no surprise to see [banks] cite geopolitical uncertainty and the absence of expected central bank interest rate cuts if loan impairment rates do go up," Mould said.

The language banks use in their guidance statements, particularly around macroeconomic overlays and sector-specific risk weightings, will be as telling as the numbers themselves.

What the numbers signal for business borrowing

For operators running UK businesses, the provisioning trend carries a practical consequence. When banks increase impairment charges, they are signalling that they expect a higher proportion of loans to sour. That expectation feeds directly into credit committees' risk appetite, which in turn shapes the terms offered to borrowers.

The Bank of England's base rate stands at its current level after a series of pauses that have frustrated expectations of easing. Market-implied rate paths for 2026, which shifted materially after the escalation of the US, Israel and Iran conflict, now suggest fewer cuts than were priced in at the start of the year. The conflict has sent inflationary ripples through energy and shipping markets, complicating the Monetary Policy Committee's calculus.

For SMEs and scale-ups, the effect is twofold. First, the cost of variable-rate borrowing remains elevated for longer than anticipated. Second, lenders building larger loss buffers are likely to tighten underwriting criteria, particularly for sectors exposed to trade disruption or discretionary consumer spending.

The 2022 precedent offers a partial roadmap. Provisions rose sharply, lending terms tightened with a lag, and some of the charges were ultimately written back. But the interim period, roughly six to nine months, was marked by reduced credit availability for smaller firms. Finance directors planning capital expenditure or acquisition activity for the second half of 2026 would do well to note the pattern.

Barclays' investment bank: windfall or warning?

Barclays occupies a distinct position among the Big Five. Its investment banking division, built on the 2008 acquisition of Lehman Brothers' North American operations, makes it the most exposed of the UK-listed banks to capital markets activity.

In Q1 2025, the investment bank generated £2.7bn in pre-tax profit, contributing 67 per cent of group-level earnings, according to the bank's filings. For Q1 2026, the division is forecast to produce £3.9bn in net income, broadly flat year on year.

Analysis from Jefferies, cited by City AM, found that Barclays' income from high-speed volatility trading is 3.5 times larger than income from traditional investment banking advisory and underwriting work. In a quarter defined by sharp market swings, that skew could prove lucrative. Wall Street peers have already demonstrated the potential: the six largest US banks reported a combined $47.4bn in pre-tax profit for Q1, with Goldman Sachs' equities division alone generating a record $5.3bn (£3.9bn) in revenue, surpassing its previous high of $4.3bn set in Q4 2025.

CS Venkatakrishnan, Barclays' group chief executive known as Venkat, has stated his intention to reduce the group's reliance on the investment bank by growing retail banking and wealth management. Progress on that strategic pivot will be closely scrutinised. A strong trading quarter may flatter the income statement, but it also underscores the concentration risk that Venkat is trying to dilute.

For the broader market, Barclays' results will serve as a barometer of whether geopolitical volatility is generating sustainable trading revenue or a short-lived spike that masks underlying pressures on lending and fee income.

The week ahead

The five sets of results will land in quick succession. The profit figures will dominate headlines. The provisioning charges, the guidance language, and the tone on credit risk will tell a more useful story about where UK lending conditions are heading for the remainder of 2026. Operators seeking debt finance in the coming quarters should pay close attention to the detail beneath the numbers.
