FTSE 100 futures plummeted over 1% in pre-market trading as investors fled equities on escalating Middle East tensions. Pound sterling fell sharply against the dollar, hitting a 2-year low, as geopolitical risk aversion surged. The sell-off follows Iran's alleged attack on a Saudi oil facility, raising fears of broader regional conflict. Market analysts warn this could trigger a sustained equity retreat and force central banks to maintain hawkish policies. Oil prices spiked over 5% at one point, reflecting immediate supply concerns.

The rout underscores how quickly sentiment can shift in volatile markets, with UK stocks now facing a potential 3-5% correction. Traders are closely monitoring Saudi Arabia's response and potential US military involvement. This sudden volatility highlights the fragility of post-pandemic market gains and the persistent impact of geopolitical shocks on global finance.
