Will the UK raise taxes in the October Budget?
·PoliticsIf the United Kingdom agrees to or announces tax-policy measures first officially announced in the Budget presented on October 28, 2026 whose combined effect increases UK tax receipts relative to the pre-Budget baseline across the full forecast period in HM Treasury's final Budget policy-decisions scorecard before Oct 29, 2026, then the market resolves to Yes.
An agreement or announcement qualifies if it involves any of the following: Formal signing of treaties Parliamentary approval with binding effect Official ratification Formal commitment by the head of state/government with constitutional authority Official statements by authorized ministers Official press releases Formal declarations during government proceedings Official statements to international bodies Phased implementation announcements and multi-party agreements where the country is a signatory also qualify. The following do NOT qualify: Preliminary discussions Conditional agreements contingent on circumstances Opposition party statements Leaked documents Think-tank recommendations General aspirations without specific commitment Draft legislation without approval Regional actions (unless specified) Retraction of previously announced commitments The net effect on tax receipts is calculated using the tax components of HM Treasury's final Budget policy-decisions scorecard and accompanying policy costings. The calculation sums qualifying tax components across all forecast-year columns, counting each once regardless of the Tax or Spend row label. Tax-receipt increases count positively and tax-receipt reductions negatively; spending components are disregarded. OBR's online scorecard may supply the component breakdown, but HM Treasury's published tax-component costings control any discrepancy. Measures first officially announced before the Budget, including before market Issuance, are excluded even if reproduced in its documents or scorecard. Spending changes, forecast revisions and actual tax collections do NOT count. The sum must be strictly positive; zero or a negative sum resolves to NO. Measures need not be legislated or in force. Only the Budget presented on October 28, 2026 qualifies; a postponed Budget does NOT count.
