On October 21, 2025, the UK economy faced challenges from rising public borrowing, a major AWS outage, and cautious signals from the Bank of England. These issues reveal
the fragile balance between fiscal policy, technological infrastructure, and market confidence as the nation approaches its next fiscal quarter.In Depth View
The UK economy dealt with a mix of problems that highlighted both fiscal and technological weaknesses. Public sector borrowing rose to £99.8 billion from April to September 2025, exceeding forecasts by £7.2 billion. September’s borrowing alone hit £20.2 billion, the highest for that month since 2020. This trend puts increased pressure on Chancellor Rachel Reeves to create a budget that reassures investors while addressing the issue of debt sustainability.
The rise in borrowing reflects a combination of increased government spending and slower growth in tax revenue. Analysts warn that continuous overshooting could weaken the UK’s credit outlook, raise borrowing costs, and diminish investor confidence. The Bank of England’s cautious approach, influenced by inflation pressures and global uncertainty, added another layer of complexity. Its signals resulted in mixed reactions in equity markets, as investors assessed the risks of tighter monetary policy against the need for economic stability.
At the same time, a major Amazon Web Services (AWS) outage disrupted cloud services across Europe, impacting banking, e-commerce, and logistics. This incident underscored the UK’s heavy reliance on cloud infrastructure for essential operations. Although AWS quickly restored functionality, the outage reminded everyone of the systemic risks associated with digital infrastructure.
Markets showed volatility, but resilience appeared in the tech and retail sectors. The FTSE 100 and FTSE 250 experienced slight fluctuations, reflecting investor caution while also showing adaptability in sectors less affected by fiscal and infrastructure issues.
