The London stock market experienced a notable decline on Thursday as uncertainty loomed over ongoing negotiations aimed at resolving the conflict in the Middle East. The FTSE 100 index fell sharply, reflecting investor concerns following Iran’s counterproposal to the US’s peace initiatives.

Market Overview

The FTSE 100 index closed down 134.67 points, a decline of 1.3%, finishing the day at 9,972.17. The FTSE 250 also suffered, dropping 179.38 points or 0.8%, to settle at 21,296.07. Meanwhile, the Aim all-share index fell by 10.18 points, closing at 719.06, a 1.4% decrease. European markets mirrored this trend, with the Cac 40 in Paris down 1.0% and Germany’s Dax 40 closing 1.5% lower.

In currency markets, the pound dipped against the dollar, trading at 1.3338, down from 1.3377 on Wednesday. However, it gained slightly against the euro, rising to 1.1563 from 1.1558. The euro itself declined against the dollar, trading at 1.1534 compared to 1.1572 the previous day.

Geopolitical Tensions Fuel Market Anxiety

The recent volatility can be traced back to escalating tensions surrounding US-Iran negotiations. President Donald Trump indicated that US military operations are progressing faster than anticipated, despite the conflict now entering its fourth week. “They’re lousy fighters, but they’re great negotiators, and they are begging to work out a deal,” Trump remarked during a White House briefing. He also noted that Iran had allowed ten oil tankers to pass through the Strait of Hormuz as a gesture of goodwill.

Iran’s response to the US’s 15-point peace plan has been to send a five-point counterproposal, which includes demands for an end to hostilities, financial compensation, and guarantees against future aggression from both Israel and the US. This back-and-forth has left investors anxious about the potential for further escalation.

Consequently, Brent crude oil prices surged to $108.80 per barrel, up from $100.91 late on Wednesday. This increase pushed oil giants like BP and Shell higher, with respective gains of 2.8% and 1.2%.

Economic Outlook Dims

The Organisation for Economic Co-operation and Development (OECD) has issued a grim forecast for the global economy, citing that the ongoing conflict has adversely affected major economies, including the UK. They now project UK inflation to average 4% in 2026, significantly higher than the previous estimate of 2.5%. The forecast for the UK’s GDP growth has also been downgraded, now expected to be 0.7% in 2026, a reduction of 0.5 percentage points from earlier predictions.

Joshua Mahony, an analyst at Scope Markets, stated, “The market rollercoaster continues, with traders waking up to the high likelihood that Trump’s five-day extension passes without an agreement.” With the deadline for the energy infrastructure strikes approaching, concerns about potential escalations are mounting.

Corporate Highlights

Amid the broader market declines, some companies reported positive earnings. Next saw its shares surge 6.4% after announcing a 21% increase in pre-tax profit, reaching £1.19 billion for the year ending January 31. The clothing retailer also reported group sales rising 11% to £7.00 billion.

In contrast, 3i Group’s shares plummeted by 18% after revealing guidance for 2026 that disappointed investors. The private equity firm highlighted that its portfolio company Action aims to open its first US store by 2028, but its growth forecast fell short of expectations.

On the Aim market, Checkit shares rose 26% following the company’s announcement of a formal sales process, citing increased interest from credible parties. Meanwhile, Playtech’s shares fell by 12% after the company reported a significant pre-tax loss of €128.6 million.

Why it Matters

The current market downturn, driven by geopolitical uncertainties and disappointing economic projections, underscores the fragility of investor confidence. With the spectre of escalating conflict in the Middle East and a potential economic slowdown in the UK, market participants are grappling with increased volatility and the implications of these global dynamics. As negotiations between the US and Iran continue, the ripple effects on oil prices and inflation rates will be closely monitored, potentially reshaping the landscape for investors and policymakers alike.
