Iran Crisis Challenges Bank of England's Quantitative Tightening Path

Key Facts

Amid a period of heightened global uncertainty, the recent Iran crisis has raised fundamental questions regarding the sustainability of the Bank of England's Quantitative Tightening (QT) program. According to reports, liquidity pressures stemming from the geopolitical shock are complicating the central bank's policy path, as market stability may require liquidity support that directly contradicts bond-selling objectives. Analysts suggest that persisting with bond sales during this crisis poses a significant risk to broader market stability.

These pressures emerge as UK economic data shows signs of cooling; mortgage approvals fell to 56.21k in June, missing the 62.9k forecast per market data. Additionally, mortgage lending dropped to £2.89 billion from a previous £4.44 billion. These figures, combined with Middle Eastern tensions, increase the burden on policymakers to re-evaluate the pace of balance sheet reduction to prevent a potential credit crunch or severe liquidity shortfall.

Traders should closely monitor upcoming policy signals following the UK Annual GDP data, which showed 0.9% growth as of June 30, 2026. The persistence of geopolitical instability remains a primary catalyst that could force a shift toward liquidity provision rather than withdrawal.
