LIVE: UK Office for Budget Responsibility appears before Treasury Committee

Commodity prices surge on supply fears

Spot oil prices rose approximately 23% and gas prices jumped 50-55% relative to pre-conflict levels, creating immediate inflationary pressure for import-dependent Britain.

Inflation trajectory revised upward

If current price levels persist, consumer prices could be 1% higher by year-end, pushing December inflation toward 3% rather than the forecast 2%.

Staggered impact on household bills

Motorists face immediate petrol price increases while household energy costs remain frozen until the OFGEM price cap resets in July, delaying the full inflationary effect.

Scale pales versus Ukraine shock

The current 50% gas price increase is far smaller than the fivefold spike seen after Russia's 2022 invasion, which required £50 billion in government support.

Minimal headroom for crisis support

With only £23 billion of fiscal headroom against borrowing rules, the government lacks capacity to fund a support package comparable to the £50 billion 2022 energy scheme without breaching targets.

Tax burden reaching historic peaks

The forecast relies on tax-to-GDP rising to 38%, a historic high for the UK, driven largely by frozen personal tax thresholds and capital tax receipts vulnerable to asset price movements.

Borrowing stuck at elevated levels

Public borrowing has persisted at roughly 5% of GDP for four years and is projected to decline only gradually to 1.6% by the medium term, leaving debt at sensitive elevated levels.

Productivity growth critical to stability

If productivity remains at decade-low levels, annual borrowing could increase by £40 billion, whereas a return to pre-financial crisis trends would improve the fiscal position by £50 billion.

SEND and defense spending pressures mount

Government commitments leave a £2 billion annual shortfall in SEND funding by 2028-29, while reaching the 3.5% GDP defense target by 2035 requires an additional £4 billion annually.

Market sensitivity constrains flexibility

With debt at elevated levels and markets highly sensitive to fiscal policy changes, the government faces limited room to absorb further shocks without triggering adverse borrowing cost reactions.
