UK government borrowing increases unexpectedly

What happened: The UK government's borrowing costs surged unexpectedly, with long-term rates reaching their highest level since 1998, driven by geopolitical risks, particularly the conflict in Iran. This increase comes despite the government undershooting its annual borrowing target by £700m. Meanwhile, US construction spending unexpectedly fell in January, indicating broad weakness in private projects.

Market impact: The rise in UK borrowing costs poses a threat to Labour's tax and spending plans, potentially forcing a re-evaluation of fiscal policy. In the US, the drop in construction spending could signal a slowdown in economic activity, impacting related sectors such as construction materials and equipment.

What to watch next: Investors should closely monitor UK government bond yields, with any further increases potentially pressuring Labour's fiscal plans. Additionally, upcoming US economic data, particularly the February construction spending report on April 1, will provide clarity on the trend in construction activity.
