£12.6bn public sector borrowing in March exceeded expectations, driven by Middle East conflict impacts. The figure, £1.4bn below last year’s level, reflects fiscal discipline but masks deeper pressures. Energy cost spikes from the Iran war have inflated government borrowing costs, even as gilt yields fell from peaks. Weaker economic activity may reduce tax revenues, while limited policy support—focusing on fixed-price energy contracts and oil-dependent households—risks further strain.

The war’s ripple effects are reshaping fiscal planning. The Resolution Foundation warns a severe escalation could push borrowing up £16bn, highlighting vulnerability. Last year’s £132bn total, 13.1% lower than forecast, underscores resilience but not immunity. Higher energy prices and potential recessionary pressures create a fragile balance. The government’s approach—targeted aid over broad subsidies—prioritizes fiscal control but may inadequately address widespread hardship.

Long-term implications hinge on conflict duration. Persistent borrowing could erode market confidence, particularly if energy costs remain volatile. Investors should monitor gilt yields and policy shifts. While current figures suggest stability, the underlying risks from geopolitical uncertainty demand vigilance. A concrete outcome remains the war’s trajectory and its economic fallout.
