Episode notes
Why The UK Is Most Vulnerable To An Energy Shock
- The UK is unusually exposed to higher borrowing costs because of weak growth and heavy reliance on imported energy.
- Low growth, high debt (around 100% of GDP) and energy import dependence amplify market fear and push up government gilt yields.
Steph’s Mortgage Rate Jump While House Buying
- Steph McGovern checked mortgage rates while buying a property and found typical two‑year fixes rose from 4.83% to 5.3% in weeks.
- She locked in her rate earlier, illustrating how the conflict rapidly reversed expectations of imminent Bank Rate cuts.

- Weak structural growth plus large low-income populations mean energy price rises hit living standards and fiscal sustainability.
- Higher benefits or targeted subsidies during a shock reduce tax revenues further and drive up government borrowing needs.
