GBPUSD still sees notable two-way risk headed into today's Budget - despite trickling details of policy measures across the UK press this morning. This week's spot recovery works against the bearish trend theme, which would resume on a break below 1.3010, the Nov 4 / 5 low, but we also see positioning dynamics possibly creating room for a GBP squeeze, raising the risk of a short squeeze given the amount of Budget scrutiny the currency has been under this month.
The front-end of the vol curve remains well elevated in anticipation of the Budget. An overnight GBPUSD straddle breaks-even on a ~90 pip swing, close to double the running YTD average, indicating greater expectations of intraday vol across the Budget today.
Compared to previous Budgets, markets are clearly cautious of not being caught offguard with market vol as was the case in 2024 - however vol gauges are still more moderate when compared to Budget events in 2022, 2023 - and in particular the Truss-Kwarteng mini-Budget 3 years ago (see below).

We still see scope for market surprises, with key uncertainties remaining over headline changes in tax, disinflationary measures, fiscal headroom and scope for Gilt sales (see more here: https://www.mnimarkets.com/articles/five-factors-that-will-drive-the-budget-market-reaction-12-1763984878006 ).
