Brent crude oil has witnessed an unprecedented surge in March 2026, climbing by 51% as conflict in Iran disrupts global markets. With the price reaching $112.57 a barrel, the escalation of tensions in the Middle East has sent shockwaves through various asset classes, prompting significant volatility in both commodities and equities. This month’s turmoil marks the largest monthly increase in oil prices in recorded history.
Brent Crude Hits Historic Highs
The geopolitical instability stemming from the Iran conflict has led to a dramatic rise in Brent crude prices, which have soared from $72.48 per barrel on February 27 to $112.57 by the end of March. Market analysts note that this increase surpasses the previous record monthly gain of 46%, which occurred during the initial Gulf War in September 1990. During March, Brent crude even peaked at $119.50, a level not seen since June 2022, as Iran effectively restricted passage through the Strait of Hormuz, a critical conduit for approximately 20% of the world’s oil and gas shipments.
The surge in oil prices has been mirrored in U.S. markets, where West Texas Intermediate (WTI) has recorded a 48% increase, marking its strongest performance since May 2020, when the global economy was grappling with the COVID-19 pandemic. Despite these rises, the broader market response has been tumultuous, with various sectors experiencing declines.
The Market’s Response: A Broader Downturn
In a striking contrast to the rally in oil, gold—typically a safe haven during times of economic uncertainty—has faced its own challenges. The price of gold has plummeted by nearly 15% since the beginning of March, positioning it for its most severe monthly decline since 2008. Factors contributing to this downward trend include significant sell-offs prompted by investors needing to liquidate positions to cover losses elsewhere in the market.
Adding to the pressure, the Turkish Central Bank’s substantial sale of approximately $3 billion in gold to bolster the lira has further exacerbated gold’s decline. The sale reduced Turkey’s reserves by nearly 50 tonnes, highlighting the interconnectedness of global markets and the impact of national policy decisions on commodity prices.
On the equities front, U.S. markets have also reacted negatively. The Dow Jones Industrial Average entered correction territory, dropping more than 10% from its recent peak. This decline occurred despite President Donald Trump’s assurances of progress in negotiations with Iran, which were initially seen as a stabilising force. However, investors are increasingly focused on the persistent supply risks posed by ongoing disruptions in the Gulf.
UK Markets and Global Implications
The fallout from rising oil prices and declining equities has not spared the UK. The FTSE 100 index fell over 8% in March, marking its worst performance since the onset of the pandemic in March 2020. The index has erased nearly all gains made in the earlier months of the year, closing below the 10,000-point mark.
Moreover, UK government bonds have experienced a significant sell-off as market participants adjusted their expectations for the Bank of England’s monetary policy. The yield on 10-year UK bonds surged nearly 17% to approach 5%, the most substantial increase since the mini-budget crisis in September 2022. Similar trends were observed across other European markets, with Italian two-year debt facing its most significant declines since May 2018.
Economist Modupe Adegbembo from Jefferies cautioned that European governments are starting from a weaker fiscal position than in the previous energy crisis, leaving them with limited capacity for substantial fiscal interventions. This could result in a more pronounced impact on demand, further straining economic growth prospects as the region grapples with rising energy prices.
Why it Matters
The current geopolitical climate underscores the fragility of global markets and the interconnectedness of commodities, equities, and government policies. The record surge in oil prices not only reflects immediate supply chain disruptions but also signals deeper vulnerabilities within the global economy. As nations navigate the complex interplay of energy dependence and political stability, the ramifications of these developments are likely to reverberate throughout financial markets, influencing growth trajectories and monetary policies for the foreseeable future.
