As tensions in the Middle East escalate, the repercussions are being felt far beyond the region, with gas prices in the UK reaching a three-year high and global stock markets experiencing notable declines. The conflict, primarily driven by recent military actions involving Israel and the United States against Iran, has left investors anxious about the potential long-term economic consequences, particularly concerning inflation and interest rates.
Gas Prices Hit Record Levels
On Tuesday, the benchmark UK gas price soared past 165p a therm, a level not seen since the early days of the Ukraine war. This increase follows a significant rise over the preceding days, doubling since airstrikes commenced on Iran last Saturday. Although the price ultimately settled at 138p a therm, it remains over 20% higher than the previous day’s rates, signalling serious market instability.
The sharp rise in gas prices stems from QatarEnergy, a leading global exporter, halting production due to military attacks on its facilities. In addition to gas, the company has also suspended the production of other materials such as aluminium, methanol, and urea, which are essential for fertiliser production. Such developments raise concerns about increased household energy bills in the UK, although the full impact may not be felt until later in the year due to existing price caps.
Stock Markets Suffer Significant Losses
The financial markets reacted swiftly to the unfolding crisis. The FTSE 100, comprising the largest companies listed in London, plummeted by 2.75% by the end of trading on Tuesday. Other European indices were similarly affected, with Germany’s DAX and France’s CAC 40 closing down 3.44% and 3.46%, respectively. In the United States, the S&P 500 saw a sharp decline at the market’s opening, ultimately ending the day down 0.9%. Asian markets were not immune either; Japan’s Nikkei index fell by 3.3%, while the Hang Seng and Shanghai Composite indices also registered losses.

Investors are grappling with the potential economic fallout from this conflict, reminiscent of the aftermath of Russia’s invasion of Ukraine four years ago, which triggered a surge in energy prices that impacted consumers and businesses globally. The UK’s Office for Budget Responsibility has warned that the current situation could have “very significant impacts on the global and UK economies.”
Shipping Routes Under Threat
The Strait of Hormuz, a vital corridor for global oil and gas supplies, has come under severe threat. Approximately 20% of the world’s energy passes through this narrow waterway, yet recent attacks on vessels have resulted in a near halt of traffic. Ebrahim Jabbari, an adviser to Iran’s Islamic Revolutionary Guard Corps, warned that any ships entering the region would face severe repercussions.
The conflict has not only driven up prices on global energy markets but has also significantly increased shipping costs. Reports indicate that hiring a supertanker to transport oil from the Middle East to China reached a staggering £298,300 per day—almost double the rates just a week prior. Sanne Manders, president of logistics technology platform Flexport, described the Strait of Hormuz as “effectively closed,” attributing this to both the unwillingness of carriers to risk passage and the reluctance of insurers to underwrite such ventures.
The Broader Economic Implications
The ramifications of rising energy costs extend beyond the immediate context of gas and oil. Higher prices inevitably translate into increased costs for transport, food, and consumer goods—factors that could exacerbate inflation. If inflation continues to rise, central banks may be less inclined to cut interest rates, further complicating economic recovery efforts.

Alasdair Locke, chairman of the Motor Fuel Group, cautioned that sustained high oil prices would inevitably lead to increased fuel costs for UK households. “The price of oil going up is going to feed through to higher prices at the pump in due course,” he stated. Ultimately, the extent of this increase will depend on the duration and magnitude of the oil price hike.
Why it Matters
The unfolding situation in the Middle East is not merely a regional crisis; it has profound implications for global economics, energy prices, and the financial markets. As the conflict escalates, the interconnectedness of our economies means that the effects will ripple across borders, affecting consumers and businesses alike. The volatility in energy prices and financial markets serves as a stark reminder of how geopolitical tensions can quickly translate into economic challenges, making the resolution of this conflict critical for stability on a global scale.
