London – Global stock markets wobbled Wednesday as escalating tensions in the Middle East fueled concerns about a potential surge in energy prices and a renewed bout of inflation. The FTSE 100 experienced its largest daily fall in eleven months on Tuesday, mirroring declines across European and US markets, as investors reacted to the rapidly evolving conflict between Israel and Iran.
The immediate trigger for the market downturn was a series of strikes across the Middle East, including Israeli bombardments in Lebanon and a drone attack on the US embassy in Riyadh, Saudi Arabia, according to reports. These actions followed initial strikes by the US and Israel on Iranian soil over the weekend, prompting retaliatory attacks from Iran and raising fears of a wider regional war. Iran has explicitly threatened to disrupt global energy supplies, particularly through the Strait of Hormuz, a critical shipping lane.
The FTSE 100 closed down 2.8% at 10,484.13 on Tuesday, even as the FTSE 250 fell 3.1% to 22,694.21 and the AIM All-Share dropped 3.6% to 786.43. Major European indexes also experienced significant losses, with the CAC 40 in Paris and the DAX 40 in Frankfurt both declining by 3.5%. Wall Street followed suit, with the Dow Jones Industrial Average down 1.7%, the S&P 500 down 1.6%, and the Nasdaq Composite down 1.7%.
Energy Prices and Inflationary Pressures
The primary driver of market anxiety is the potential impact on global energy prices. Brent crude oil traded at $83.06 a barrel on Tuesday afternoon, up from $77.92 at the same time on Monday, according to reports. Economists warn that sustained higher oil and natural gas prices could reignite inflationary pressures, potentially forcing central banks to maintain or even raise interest rates. “The longer oil and natural gas prices remain elevated, the greater the risk of a meaningful impact on inflation which could mean higher interest rates, an event that’s typically negative for equity markets,” said Dan Coatsworth, head of markets at AJ Bell.
The UK is particularly vulnerable due to its reliance on imported energy. The UK gas price surged to its highest level in three years on Tuesday, nearly doubling in two days to highs of 165p a therm before settling at 138p a therm – still over a fifth higher than Monday’s price. S&P Global Market Intelligence director Raj Badiani cautioned that a prolonged conflict could lead to a “steep rise in UK industrial and residential energy bills” when the novel energy price is announced on July 1, potentially pushing up headline inflation in the second half of the year.
Reeves’s Spring Statement and Economic Forecasts
The market turmoil unfolded shortly after Chancellor Rachel Reeves delivered her Spring Statement, presenting new forecasts from the Office for Budget Responsibility (OBR). While the OBR revised down growth forecasts for 2026, it modestly upgraded projections for future years. However, economists in the City quickly questioned the relevance of these forecasts given the rapidly changing geopolitical landscape. The OBR also warned that the conflict in the Middle East could have a “very significant” impact on the UK economy, as reported by The Guardian.
The uncertainty surrounding the conflict also impacted the UK bond market, with the 10-year gilt yield rising around 20 basis points before settling 10 basis points higher. This indicates increased borrowing costs for the government.
Shipping Disruption Concerns
Adding to the concerns, reports indicate that insurance coverage for ships passing through the Strait of Hormuz has been removed, effectively closing a key shipping lane. Joshua Mahony at Scope Markets noted that this development represents an “effective closure” of the strait, potentially disrupting global trade flows. Iran’s Revolutionary Guards have also threatened to “burn any ship” attempting to navigate the waterway, further exacerbating the situation.
The situation remains fluid, and markets are likely to remain volatile in the coming days and weeks. Investors are closely monitoring developments in the Middle East and assessing the potential impact on the global economy. The next key data point will be the announcement of the new energy price cap on July 1, which will provide a clearer picture of the potential inflationary pressures facing the UK.
