FTSE 100 Share Price Decline
The FTSE 100 has slumped nearly 8% since the Iran conflict began, dropping from 10,900 to around 10,100. On March 9, 2026, the index closed down 35.23 points, or 0.3%, at 10,249.52.
In addition to the FTSE 100, the FTSE 250 ended down 357.65 points, or 1.6%, at 22,143.30, while the AIM all-share closed down 17.46 points, or 2.2%, at 767.24.
The recent decline in the FTSE 100 reflects broader market concerns, particularly as Brent crude oil prices have surged. Brent oil was higher at 100.02 dollars a barrel on Monday afternoon, up from 90.85 late on Friday, and traded as high as 119.25 dollars a barrel earlier in the day.
Market analysts are closely monitoring the situation, with Helima Croft stating, “With no clear definition of what winning looks like, it is hard to forecast whether this will be a multi-week or multi-month conflict.” This uncertainty contributes to the volatility in the markets.
The yield on a ten-year gilt briefly touched 4.78 percent on Monday morning, its highest since October, while the yield on a two-year gilt rose above 4.23 percent for the first time in a year.
Historically, the FTSE 100 has dropped 6 percent since the end of February but remains 3 percent above where it started in 2026. This context highlights the ongoing fluctuations in investor sentiment amid geopolitical tensions.
As Warren Buffett famously said, “be greedy when others are fearful,” a sentiment that may resonate with investors navigating this turbulent period.
Details remain unconfirmed regarding the potential long-term impacts of the Iran conflict on the FTSE 100 and broader market trends.
