Prime Minister Andy Burnham has announced the removal of the 5% VAT charge on household electricity bills from 1 October, positioning it as the opening measure in a wider cost-of-living package. The government estimates the change will save families about £45 a year, while costing £850mn in 2026–27, and says it will be financed by dropping the previous administration’s digital ID plan. Officials added that the move could reduce headline inflation by 0.1 percentage point.
Market reaction has been cautious, with weakness in gilts and sterling drawing attention to concerns around fiscal credibility and whether the easing is fully funded. The policy sits alongside discussion of potential business-rates relief, though broader energy price pressures remain elevated.
Debt Markets and Fiscal Risk Strategies
With the October 1 energy tax cut looming, we expect pressure on UK government debt to intensify over the coming weeks as markets question the government’s funding plans. Given that 10-year Gilt yields have already crept back up toward the 4.3% mark in recent weeks, we should look to short gilt futures or buy put options on UK debt. This positioning protects our portfolios against further yield spikes as investors demand a higher premium for UK fiscal risk.
Sterling Vulnerability and Inflation Hedges
We also suggest targeting the British Pound, which has shown clear vulnerability, dropping near the 1.27 level against the US dollar following the fiscal announcement. Derivative traders can exploit this downward trend by buying short-term GBP/USD put options to hedge against a broader sell-off. Historically, unfunded fiscal measures in the UK, such as those seen during the 2022 mini-budget crisis when sterling hit historic lows, have led to rapid currency depreciation.
While the projected 0.1 percentage point drop in headline inflation might prompt some to price in immediate rate cuts, we believe the structural fiscal deficit will keep long-term inflation expectations elevated. We recommend entering into payer inflation swaps, which will benefit if long-term UK inflation expectations rise despite the short-term VAT relief. This balanced approach allows us to capitalize on the discrepancy between immediate consumer relief and long-term fiscal credibility concerns.
