Britain's factory sector showed signs of revival in December, expanding at the fastest pace in 15 months according to the final S&P Global Purchasing Managers' Index (PMI) for manufacturing. The index climbed to 50.6 from 50.2 in November, surpassing contraction territory for the first time since prior to a 13-month downturn, though it fell short of the initial flash estimate of 51.2.

Key Drivers of December's Uptick

Several factors contributed to the modest growth. Stock-building played a role, while new orders increased slightly for the first time since September 2024. Exports and hiring showed stabilisation after periods of weakness. Relief from Finance Minister Rachel Reeves' recent budget, which imposed 26 billion in tax hikes but delayed most and spared businesses from harsher measures unlike her 2024 budget, helped ease uncertainty.

The recovery at carmaker Jaguar Land Rover, following a cyber-attack shutdown, also provided a boost. Additionally, the Bank of England's recent interest rate cut is expected to support demand in the coming months.

Lingering Concerns for 2026

Despite the positive PMI reading, challenges loom. Business optimism fell in December for the first time in three months, with firms citing high costs, increased taxation, reduced international competitiveness, geopolitical uncertainty and potential government policy impacts as key worries.

Inflation pressures ticked higher, driven by elevated labour costs stemming from Reeves' 2024 payroll tax hike. The Bank of England had previously forecast zero growth for the fourth quarter of 2025, reflecting an economy struggling for momentum amid budget anticipation.

Rob Dobson, director at S&P Global Market Intelligence, cautioned that 'the start of 2026 will show if growth can be sustained after these temporary boosts subside.' He noted the rate cut's potential benefits but highlighted persistent headwinds.

Broader Economic Context

• The manufacturing uptick aligns with a preliminary services PMI reaching a two-month high, with final data due Tuesday.
• The economy faces tests from weakening consumer spending and global risks, even as the FTSE 100 enjoyed strong 2025 gains.

This PMI marks a cautious bright spot for UK industry, but sustained expansion will hinge on navigating fiscal pressures and external shocks in the year ahead.
