OBR Economist Discusses Budget Mistake, Tax Hikes, and UK Economic Outlook

OBR Budget Release Incident

• 🚨 An investigation is underway, led by Baroness Sarah Hawke and Professor Kieran Martin, into a serious incident involving the early release of budget measures.
• 🔍 The investigation aims to uncover what happened, ensure it doesn't recur, and will report to the Treasury Select Committee and the Chancellor within days.

UK Budget and Tax Increases

• 📈 The recent budget includes one of the largest tax-raising measures on record, with policy measures expected to raise approximately £26 billion in extra revenues, primarily in future years.
• 📊 Despite substantial tax rises and spending increases, the Office for Budget Responsibility (OBR) forecasts minimal impact on economic output by 2030.
• ⚠️ The UK tax burden is projected to reach 38% of GDP, the highest level since shortly after World War II.

Economic Growth Forecasts

• 📉 The OBR has downgraded economic growth forecasts for the UK, not due to government measures, but a reassessment of the realistic trend productivity growth rate.
• 📉 The downgrade reflects a disappointing failure to see a bounce-back in productivity growth after the shocks of COVID-19 and energy price rises.
• 📊 The central estimate for UK output growth is now around 1.5% per year by historical standards.

Budgetary Measures and Concerns

• 🧩 The budget employs a series of diverse measures rather than focusing on a single large tax reform.
• 💰 A significant portion of the revenue is expected from a freeze in income tax thresholds, continuing a policy from 2022.
• ⏳ There are concerns about the backloading of tax increases, with spending occurring earlier than the revenue generation from tax hikes.

Forecast Uncertainty and Headroom

• ⚖️ OBR estimates for revenue are central forecasts, acknowledging risks and uncertainties, including novel measures like the mileage levy on electronic vehicles.
• 📈 The pre-measures forecast indicated a very small buffer of about £4 billion to meet the government's budget balance target, necessitating policy tightening.
• 📊 The government chose a package of measures to build headroom, with market rate paths agreed upon at the start of the forecasting process.
