Jim O'Neill on UK Economy, Taxes

Former Goldman Sachs chief economist Jim O’Neill warned that proposed UK tax increases on banks and businesses could undermine economic growth. He said the recent rise in gilt yields could reverse before the October 28 budget, leaving uncertainty over Chancellor John Healey’s required tax-and-spend measures.

Analysis

The investable issue is not the commentary itself but the budget’s potential to reprice UK bank earnings durability. BARC.L, LLOY.L and NWG.L have unusually high domestic exposure to a combination of bank-levy/tax risk, weaker loan growth and a possible reversal in long-end gilt yields; the latter would reduce reinvestment income and could pressure net-interest-income expectations. A tax increase is therefore more damaging than its direct EPS effect if it prompts analysts to lower payout assumptions and apply a wider UK-policy discount to excess capital.

Near term, this is not a signal to trade GS: its UK revenue exposure is too diversified and indirect for a domestic fiscal headline to move group estimates materially. Over the next 1-3 months, gilt volatility and pre-budget leaks matter more than the final tax rate because they determine whether fiscal tightening is interpreted as credibility-enhancing or growth-destructive. The contrarian case is that a credible fiscal package compresses the gilt term premium, lowers mortgage funding costs and ultimately supports UK credit demand; that outcome would favor domestically geared banks after an initial policy-risk selloff.

For a 6-18 month horizon, the key second-order risk is a feedback loop from higher business taxation into lower investment, weaker SME lending and increased impairments—most acute for LLOY.L and NWG.L. Falsification of the bearish domestic-bank view would be stable or rising 2026 NII guidance, no incremental sector-specific levy, and a sustained decline in UK 10-year gilt yields without deterioration in PMI or unemployment data.

Key Decisions for Investors

• Do not initiate a directional GS position on this development; monitor UK investment-banking fee commentary and sterling/gilt volatility instead, as any impact on GS is second-order and unlikely to alter consensus earnings.
• Ahead of the October 28 budget, favor a hedged UK-bank expression: long HSBA.L / short equal-beta LLOY.L or NWG.L for 1-3 months. HSBC’s geographic earnings mix should be relatively insulated from UK fiscal drag; exit if proposed bank-specific measures are excluded or if the domestic-bank spread widens materially before details emerge.
• For existing BARC.L, LLOY.L and NWG.L longs, reduce exposure or buy short-dated downside protection into budget leaks rather than sell indiscriminately. The risk/reward is asymmetric if a bank levy is announced: direct EPS pressure can be compounded by lower payout multiples, while a benign outcome can be re-entered after policy clarity.
• Set a macro trigger on UK 10-year gilt yields: a sustained move lower alongside stable growth indicators supports adding domestic banks after the budget; yields rising on fiscal credibility concerns would favor maintaining the HSBA.L versus domestic-bank hedge and avoiding UK credit-sensitive cyclicals.
