Middle East conflict pushes UK borrowing outlook into uncertainty

Middle East conflict pushes UK borrowing outlook into uncertainty- UK government borrowing has fallen to a three-year low, offering a brief moment of relief for public finances, but economists warn that a worsening geopolitical situation in the Middle East could quickly reverse the improvement and place fresh pressure on the Treasury.

According to the Office for National Statistics (ONS), public sector net borrowing — the difference between government spending and tax income — fell by £19.8 billion to £132 billion in the financial year ending March. This marks the lowest level since 2022–23, and comes in slightly below the £132.7 billion forecast by the Office for Budget Responsibility (OBR), the UK’s independent fiscal watchdog.

While the figures suggest a modest improvement in the state of public finances, analysts stress that the outlook is becoming increasingly fragile due to external shocks, particularly rising energy costs linked to tensions involving Iran and the wider Middle East.

Energy shock drives new economic uncertainty

The escalation of conflict involving the US, Israel, and Iran has triggered renewed volatility in global energy markets. A key concern is the Strait of Hormuz, a narrow but strategically vital shipping route that carries around 20% of global oil and liquefied natural gas supplies.

Any disruption in this corridor immediately affects global energy prices, and markets have already responded with a sharp increase in crude oil and gas costs. These increases have fed through into higher petrol and diesel prices in the UK, with households and businesses already beginning to feel the impact.

Economists warn that the current inflationary pressure is only the early stage of the shock. As energy costs filter through supply chains, further price increases are expected in the coming months, potentially reversing recent progress in bringing inflation under control.

Inflation risks threaten fiscal stability

Higher energy prices are particularly significant for the UK economy because they directly influence inflation — the rate at which prices rise. After a period of easing inflation, the recent energy spike risks pushing price growth upward again.

Ruth Gregory, deputy chief UK economist at Capital Economics, said the “full impact from the energy price shock is still to come”, warning that households and businesses have not yet absorbed the full effect of higher global energy costs.

If inflation accelerates again, it could force the government into a difficult position. Higher inflation typically leads to increased spending on areas such as pensions, welfare payments, and public sector wages. At the same time, the government may come under political pressure to introduce new support measures for households, such as energy bill subsidies or cost-of-living assistance.

Such interventions would weaken the recent improvement in borrowing figures and potentially push public debt higher once again.

Growth downgrade adds further pressure

The International Monetary Fund (IMF) has already responded to the global energy shock by revising down its UK growth forecast. It now expects UK GDP to grow by just 0.8% this year, down from an earlier projection of 1.3%.

The IMF warned that the UK could be among the most affected advanced economies, due to its reliance on energy imports and sensitivity to inflationary pressures.

Slower economic growth presents another challenge for the government’s fiscal position. Weak growth tends to reduce tax revenues from income tax, corporate tax, and consumption-based taxes such as VAT, while simultaneously increasing demand for public spending.

Temporary improvement in public finances

Despite the uncertain outlook, the latest borrowing figures show that the UK has made some progress in stabilising its public finances over the past year. The fall to £132 billion in borrowing suggests that tax revenues have held up reasonably well and that some pandemic-era and cost-of-living-related spending pressures have eased.

The fact that borrowing came in slightly below the OBR’s forecast also indicates that fiscal performance has been marginally better than expected.

However, analysts caution that this improvement may prove short-lived. Much of the recent stability was achieved in a relatively calm energy environment, before the latest geopolitical escalation disrupted global markets.

Outlook: fragile balance between inflation and growth

Looking ahead, the UK economy now faces a delicate balancing act between inflation risks and slowing growth.

On one hand, higher energy prices threaten to reignite inflation, increasing pressure on households and forcing the government to consider further support measures. On the other hand, weaker growth risks undermining tax revenues and widening the budget deficit.

Key risks identified by economists include:

• Sustained disruption in Middle East energy routes, particularly the Strait of Hormuz
• Renewed inflation pressures feeding into wages and public spending
• Possible government intervention to cushion households from rising energy bills
• Slower economic growth reducing tax income and weakening fiscal stability

Together, these factors could quickly erase the recent improvement in borrowing and push the UK back into a more challenging fiscal position.

Final Thoughts

While the fall in government borrowing to a three-year low offers short-term reassurance, the broader economic picture is increasingly shaped by external risks beyond the UK’s control. The escalation of conflict in the Middle East has introduced fresh uncertainty into global energy markets, and its full impact on inflation, growth, and public finances has yet to be felt.

For now, the UK’s fiscal position appears stable — but that stability may depend heavily on how long energy markets remain volatile and whether inflationary pressures continue to build in the months ahead.
